-# tkblt
-Introduction to the TkBLT library
-
-TkBLT is a library of extensions to the Tk library. It adds new
-commands and variables to the application's interpreter.
-
-TkBLT is a derived version of the BLT Toolkit by George A. Howlett,
-for Tcl/Tk 8.5/8.6, is TEA compatible, with full support for MacOSX and
-Windows, and is fully compatible with the Tk API. TkBLT is released
-under the original BSD license. TkBLT includes only the Graph and
-Barchart Tk widgets, and the Tcl Vector command.
-
-The following commands are added to the interpreter from the TkBLT library:
-
-Graph: A 2D plotting widget. Plots two variable data in a window with an optional 
-legend and annotations. It has of several components; coordinate axes, 
-crosshairs, a legend, and a collection of elements and tags.
-
-Barchart: A barchart widget. Plots two-variable data as rectangular bars in a 
-window. The x-coordinate values designate the position of the bar along 
-the x-axis, while the y-coordinate values designate the magnitude.
-The barchart widget has of several components; coordinate axes, 
-crosshairs, a legend, and a collection of elements and tags.
-
-Vector: Creates a vector of floating point values. The vector's components
-can be manipulated in three ways: through a Tcl array variable, a Tcl
-command, or the C API.

-Usage: $0 [OPTION]... [VAR=VALUE]...
-
-To assign environment variables (e.g., CC, CFLAGS...), specify them as
-VAR=VALUE.  See below for descriptions of some of the useful variables.
-
-Defaults for the options are specified in brackets.
-
-Configuration:
-  -h, --help              display this help and exit
-      --help=short        display options specific to this package
-      --help=recursive    display the short help of all the included packages
-  -V, --version           display version information and exit
-  -q, --quiet, --silent   do not print \`checking ...' messages
-      --cache-file=FILE   cache test results in FILE [disabled]
-  -C, --config-cache      alias for \`--cache-file=config.cache'
-  -n, --no-create         do not create output files
-      --srcdir=DIR        find the sources in DIR [configure dir or \`..']
-
-Installation directories:
-  --prefix=PREFIX         install architecture-independent files in PREFIX
-                          [$ac_default_prefix]
-  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX
-                          [PREFIX]
-
-By default, \`make install' will install all the files in
-\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc.  You can specify
-an installation prefix other than \`$ac_default_prefix' using \`--prefix',
-for instance \`--prefix=\$HOME'.
-
-For better control, use the options below.
-
-Fine tuning of the installation directories:
-  --bindir=DIR            user executables [EPREFIX/bin]
-  --sbindir=DIR           system admin executables [EPREFIX/sbin]

-<H2>DESCRIPTION</H2><PRE>
-       The  <B>barchart</B>  command creates a bar chart for plotting two-dimensional
-       data (X-Y coordinates). A bar chart is a  graphic  means  of  comparing
-       numbers by displaying bars of lengths proportional to the y-coordinates
-       of the points they represented.  The bar chart  has  many  configurable
-       components: coordinate axes, elements, legend, grid lines, cross hairs,
-       etc.  They allow you to customize the look and feel of the graph.
-
-
-</PRE>
-<H2>INTRODUCTION</H2><PRE>
-       The <B>barchart</B> command creates a new window for plotting  two-dimensional
-       data  (X-Y coordinates), using bars of various lengths to represent the
-       data points.  The bars are drawn in a rectangular area displayed in the
-       center  of  the new window.  This is the <I>plotting</I> <I>area</I>.  The coordinate
-       axes are drawn in  the  margins  surrounding  the  plotting  area.   By
-       default,  the  legend  is drawn in the right margin.  The title is dis-
-       played in top margin.
-
-       A <B>barchart</B> widget has several configurable components: coordinate axes,
-       data elements, legend, grid, cross hairs, pens, postscript, and annota-
-       tion markers.  Each component can be queried or modified.
-
-       axis       Up to four coordinate axes (two X-coordinate and two Y-coor-
-                 dinate axes) can be displayed, but you can create and use any
-                 number of axes. Axes control what region of data is displayed
-                 and  how  the  data is scaled. Each axis consists of the axis
-                 line, title, major and minor ticks,  and  tick  labels.  Tick
-                 labels display the value at each major tick.
-
-       crosshairs
-                 Cross  hairs  are used to position the mouse pointer relative
-                 to the X and Y  coordinate  axes.  Two  perpendicular  lines,
-                 intersecting  at  the  current  location of the mouse, extend
-                 across the plotting area to the coordinate axes.
-
-       element   An element represents a set of data to be plotted.   It  con-
-                 tains  an  x  and  y  vector  of values representing the data
-                 points.  Each data point is displayed  as  a  bar  where  the
-                 length  of the bar is proportional to the ordinate (Y-coordi-
-                 nate) of the data point.  The appearance of the bar, such  as
-                 its color, stipple, or relief is configurable.
-
-                 A  special  case exists when two or more data points have the
-                 same abscissa (X-coordinate).  By default, the bars are over-
-                 layed,  one  on  top of the other.  The bars are drawn in the
-                 order of the element display list.  But you can also  config-
-                 ure  the bars to be displayed in two other ways.  They may be

-<H2>EXAMPLE</H2><PRE>
-       The <B>barchart</B> command creates a new bar  chart.   #  Create  a  new  bar
-       chart.   Plotting  area  is black.  barchart .b -plotbackground black A
-       new Tcl command .b is created.  This command can be used to  query  and
-       modify the bar chart.  For example, to change the title of the graph to
-       "My Plot", you use the new command  and  the  <B>configure</B>  operation.   #
-       Change  the title.  .b configure -title "My Plot" To add data elements,
-       you use the command and the <B>element</B> component.  # Create a new  element
-       named  "e1" .b element create e1 \      -xdata { 1 2 3 4 5 6 7 8 9 10 }
-       \       -ydata  {  26.18  50.46  72.85  93.31  111.86   128.47   143.14
-                 155.85  166.60  175.38  }  The  element's X-Y coordinates are
-       specified using lists of numbers.  Alternately, BLT  vectors  could  be
-       used to hold the X-Y coordinates.  # Create two vectors and add them to
-       the barchart.  vector xVector yVector xVector set { 1 2 3 4 5 6 7  8  9
-       10  } yVector set { 26.18 50.46 72.85 93.31 111.86 128.47 143.14 155.85
-            166.60 175.38 } n.b element create e1 -xdata xVector -ydata  yVec-
-       tor  The  advantage  of  using vectors is that when you modify one, the
-       sure we change the bar width  too.   .b  configure  -barwidth  0.2  The
-       height  of  each  bar is proportional to the ordinate (Y-coordinate) of
-       the data point.
-
-       If two or more data points have the same abscissa (X-coordinate value),
-       the  bars  representing those data points may be drawn in various ways.
-       The default is to overlay the bars, one  on  top  of  the  other.   The
-       ordering  is  determined  from  the  of  element  display list.  If the
-       stacked mode is selected (using the <B>-barmode</B> configuration option), the
-       bars  are stacked, each bar above the previous.  # Display the elements
-       as stacked.  .b configure -barmode  stacked  If  the  aligned  mode  is
-       selected,  the bars having the same x-coordinates are displayed side by
-       side.  The width of each bar is a fraction of its normal  width,  based
-       upon the number of bars with the same x-coordinate.  # Display the ele-
-       ments side-by-side.  .b configure -barmode aligned By default, the ele-
-       ment's  label in the legend will be also e1.  You can change the label,
-       or specify no legend entry, again using the element's <B>configure</B>  opera-
-       tion.   #  Don't  display  "e1" in the legend.  .b element configure e1
-       -label "" You can configure more than just  the  element's  label.   An
-       element  has many attributes such as stipple, foreground and background
-       colors, relief, etc.  .b element  configure  e1  -fg  red  -bg  pink  \
-            -stipple gray50 Four coordinate axes are automatically created: x,
-       x2, y, and y2.  And by default, elements are mapped onto the axes x and
-       y.   This  can be changed with the <B>-mapx</B> and <B>-mapy</B> options.  # Map "e1"
-       on the alternate y axis "y2".  .b element configure e1  -mapy  y2  Axes
-       can  be configured in many ways too.  For example, you change the scale
-       of the Y-axis from linear to log using the <B>axis</B> component.  # Y-axis is
-       log  scale.   .b  axis configure y -logscale yes One important way axes
-       are used is to zoom in on a particular data region.  Zooming is done by
-       simply specifying new axis limits using the <B>-min</B> and <B>-max</B> configuration
-       options.  .b axis configure x -min 1.0 -max 1.5  .b  axis  configure  y
-       -min  12.0 -max 55.15 To zoom interactively, you link the<B>axis</B> <B>configure</B>
-       operations with some user interaction (such as pressing the mouse  but-
-       ton),  using  the  <B>bind</B>  command.   To convert between screen and graph
-       coordinates, use the <B>invtransform</B> operation.  # Click the button to set
-       a new minimum bind .b &lt;ButtonPress-1&gt; {
-           %W axis configure x -min [%W axis invtransform x %x]
-           %W  axis configure x -min [%W axis invtransform x %y] } By default,
-       the limits of the axis are determined from data values.  To reset  back
-       to  the  default  limits,  set  the  <B>-min</B> and <B>-max</B> options to the empty
-       value.  # Reset the axes to autoscale again.  .b axis configure x  -min
-       {}  -max  {} .b axis configure y -min {} -max {} By default, the legend
-       is drawn in the right margin.  You can change this or any  legend  con-
-       figuration  options using the <B>legend</B> component.  # Configure the legend
-       font, color, and relief .b  legend  configure  -position  left  -relief
-       raised  \       -font  fixed  -fg blue To prevent the legend from being
-       displayed, turn on the <B>-hide</B> option.  # Don't display the  legend.   .b
-       legend  configure  -hide yes The <B>barchart</B> has simple drawing procedures
-       called markers.  They can be used to highlight or annotate data in  the
-       graph.  The types of markers available are bitmaps, polygons, lines, or
-       windows.  Markers can be used, for example, to mark  or  brush  points.
-       For  example  there may be a line marker which indicates some low-water
-       chart into file "file.ps" .b postscript  output  file.ps  -maxpect  yes
-       -decorations  no  This generates a file file.ps containing the encapsu-
-       lated PostScript of the graph.  The option <B>-maxpect</B> says to  scale  the
-       plot  to  the  size  of  the page.  Turning off the <B>-decorations</B> option
-       denotes that no borders or color backgrounds should be drawn (i.e.  the
-       background of the margins, legend, and plotting area will be white).

-
-              <B>-plotrelief</B> <I>relief</I>
-                     Specifies  the  3-D effect for the plotting area.  <I>Relief</I>
-                     specifies how the interior of the  plotting  area  should
-                     appear relative to rest of the graph; for example, raised
-                     means the plot should appear to protrude from the  graph,
-                     relative  to  the  surface  of the graph.  The default is
-                     sunken.
-
-              <B>-relief</B> <I>relief</I>
-                     Specifies the 3-D effect for the barchart widget.  <I>Relief</I>
-                     specifies  how the graph should appear relative to widget
-                     it is packed into; for example, raised  means  the  graph
-                     should appear to protrude.  The default is flat.
-
-              <B>-rightmargin</B> <I>pixels</I>
-                     Sets  the  size  of  margin from the plotting area to the
-                     right edge of the window.   By  default,  the  legend  is
-                     drawn  in  this  margin.  If <I>pixels</I> is than 1, the margin
-                     size is selected automatically.
-
-              <B>-takefocus</B> <I>focus</I>
-                     Provides information used when moving the focus from win-
-                     dow  to  window  via  keyboard  traversal  (e.g., Tab and
-                     Shift-Tab).  If <I>focus</I> is 0, this means that  this  window
-                     should  be skipped entirely during keyboard traversal.  1
-                     means that the this  window  should  always  receive  the
-                     input  focus.   An  empty  value means that the traversal
-                     scripts make the decision whether to focus on the window.
-                     The default is "".

-
-       <I>pathName</I> <B>transform</B> <I>x</I> <I>y</I>
-       A graph is composed of several components: coordinate axes,  data  ele-
-       ments,  legend,  grid, cross hairs, postscript, and annotation markers.
-       Instead of one big set of configuration  options  and  operations,  the
-       graph  is  partitioned,  where each component has its own configuration
-       options and operations that specifically control that aspect or part of
-       the graph.
-
-   <B>AXIS</B> <B>COMPONENTS</B>
-       Four  coordinate  axes are automatically created: two X-coordinate axes
-       (x and x2) and two Y-coordinate axes (y, and y2).  By default, the axis
-       x  is located in the bottom margin, y in the left margin, x2 in the top
-       margin, and y2 in the right margin.
-
-       An axis consists of the axis line, title, major and  minor  ticks,  and
-       tick  labels.   Major  ticks  are  drawn at uniform intervals along the
-       axis.  Each tick is labeled with its coordinate value.  Minor ticks are
-       drawn at uniform intervals within major ticks.
-
-       The  range  of  the axis controls what region of data is plotted.  Data
-       points outside the minimum and maximum limits of the axis are not plot-
-       ted.   By  default,  the minimum and maximum limits are determined from
-       the data, but you can reset either limit.
-
-       You can create and use several axes. To create an axis, invoke the axis
-       component  and  its create operation.  # Create a new axis called "tem-
-       perature" .b axis create temperature You map data elements to  an  axis
-       using the element's -mapy and -mapx configuration options. They specify
-       the coordinate axes an element is mapped onto.  # Now map the  tempera-
-       ture  data  to  this  axis.   .b element create "temp" -xdata $x -ydata
-       $tempData \
-           -mapy temperature While you can have many axes, only four axes  can
-       be  displayed  simultaneously.   They  are drawn in each of the margins
-       surrounding the plotting area.  The axes x and y are drawn in the  bot-
-       tom  and  left  margins.  The axes x2 and y2 are drawn in top and right
-       margins.  Only x and y are shown by default. Note  that  the  axes  can
-       have different scales.
-
-       To  display  a  different  axis, you invoke one of the following compo-
-       nents: <B>xaxis</B>, <B>yaxis</B>, <B>x2axis</B>, and <B>y2axis</B>.  The <B>use</B> operation  designates
-       the  axis to be drawn in the corresponding margin: <B>xaxis</B> in the bottom,
-       <B>yaxis</B> in the left, <B>x2axis</B> in the top, and <B>y2axis</B> in the right.  #  Dis-
-       play the axis temperature in the left margin.  .b yaxis use temperature
-
-       You can configure axes in many ways. The axis scale can  be  linear  or
-       logarithmic.   The  values  along  the  axis  can  either monotonically
-       increase or decrease.  If you need custom tick labels, you can  specify
-       a  Tcl procedure to format the label any way you wish.  You can control
-       how ticks are drawn, by changing the major tick interval or the  number
-       of minor ticks.  You can define non-uniform tick intervals, such as for
-       time-series plots.
-
-
-              <B>-autorange</B> <I>range</I>
-                     Sets the range of values for the axis to <I>range</I>.  The axis
-                     limits are automatically reset to display the most recent
-                     data points in this range.  If <I>range</I> is 0.0, the range is
-                     determined  from the limits of the data.  If <B>-min</B> or <B>-max</B>
-                     are specified, they override this option.  The default is
-                     0.0.
-
-              <B>-color</B> <I>color</I>
-                     Sets  the color of the axis and tick labels.  The default
-                     is black.
-
-              <B>-command</B> <I>prefix</I>
-                     Specifies a Tcl command to be invoked when formatting the
-                     axis  tick labels. <I>Prefix</I> is a string containing the name
-                     of a Tcl proc and any extra arguments for the  procedure.
-                     This  command is invoked for each major tick on the axis.
-                     Two additional arguments are passed to the procedure: the
-                     pathname  of the widget and the current the numeric value
-                     of the tick.  The procedure returns  the  formatted  tick
-                     label.   If  "" is returned, no label will appear next to
-                     the tick.  You can get the standard tick labels again  by
-                     setting <I>prefix</I> to "".  The default is "".
-
-                     Please  note that this procedure is invoked while the bar
-                     chart is redrawn.  You may query the widget's  configura-
-                     tion options.  But do not reset options, because this can
-                     have unexpected results.
-
-              <B>-descending</B> <I>boolean</I>
-                     Indicates whether the values along the axis are monotoni-
-                     cally  increasing or decreasing.  If <I>boolean</I> is true, the
-                     axis values will be decreasing.  The default is 0.
-
-              <B>-hide</B> <I>boolean</I>
-                     Indicates whether the axis is displayed.
-
-              <B>-justify</B> <I>justify</I>
-                     Specifies how the axis title should be  justified.   This
-                     matters  only  when the axis title contains more than one
-                     line of text. <I>Justify</I> must be  left,  right,  or  center.
-                     The default is center.
-
-              <B>-limits</B> <I>formatStr</I>
-                     Specifies a printf-like description to format the minimum
-                     and maximum limits of the axis.  The limits are displayed
-                     at  the  top/bottom  or  left/right sides of the plotting
-                     area.  <I>FormatStr</I> is a list of one or two format  descrip-
-                     tions.   If one description is supplied, both the minimum
-                     and maximum limits are formatted in  the  same  way.   If
-                     two,  the  first  designates  the  format for the minimum
-                     limit, the second for the maximum.  If  ""  is  given  as
-                     data points tightly, at the  outermost  data  points,  or
-                     loosely,  at  the outer tick intervals.  This is relevant
-                     only when the axis limit is automatically calculated.  If
-                     <I>boolean</I>  is true, the axis range is "loose".  The default
-                     is 0.
-
-              <B>-majorticks</B> <I>majorList</I>
-                     Specifies where to display major axis ticks.  You can use
-                     this  option  to  display ticks at non-uniform intervals.
-                     <I>MajorList</I> is a list of axis coordinates  designating  the
-                     location  of  major ticks.  No minor ticks are drawn.  If
-                     <I>majorList</I> is "", major ticks will be  automatically  com-
-                     puted. The default is "".
-
-              <B>-max</B> <I>value</I>
-                     Sets  the  maximum  limit  of  <I>axisName</I>.   Any data point
-                     greater than <I>value</I> is not displayed.  If <I>value</I> is "", the
-                     maximum limit is calculated using the largest data value.
-                     The default is "".
-
-              <B>-min</B> <I>value</I>
-                     Sets the minimum limit of <I>axisName</I>. Any data  point  less
-                     than <I>value</I> is not displayed.  If <I>value</I> is "", the minimum
-                     limit is calculated using the smallest data  value.   The
-                     default is "".
-
-              <B>-minorticks</B> <I>minorList</I>
-                     Specifies where to display minor axis ticks.  You can use
-                     this option to display minor ticks at non-uniform  inter-
-                     vals.  <I>MinorList</I>  is  a list of real values, ranging from
-                     0.0 to 1.0, designating the placement of  a  minor  tick.
-                     No minor ticks are drawn if the <B>-majortick</B> option is also
-                     set.  If <I>minorList</I> is "", minor ticks will  be  automati-
-                     cally computed. The default is "".
-
-              <B>-rotate</B> <I>theta</I>
-                     Specifies  the  how  many degrees to rotate the axis tick
-                     labels.  <I>Theta</I> is a real value representing the number of
-                     degrees  to  rotate  the tick labels.  The default is 0.0
-                     degrees.
-
-              <B>-shiftby</B> <I>value</I>
-                     Specifies how much to automatically shift  the  range  of
-                     the  axis.   When  the  new data exceeds the current axis
-                     maximum, the maximum is increased in increments of <I>value</I>.
-                     You  can  use this option to prevent the axis limits from
-                     being recomputed at each new time point. If <I>value</I> is 0.0,
-                     then no automatic shifting is down. The default is 0.0.
-
-              <B>-showticks</B> <I>boolean</I>
-                     Indicates  whether axis ticks should be drawn. If <I>boolean</I>
-                     is true, ticks are drawn.  If false, only the  axis  line
-
-              <B>-tickfont</B> <I>fontName</I>
-                     Specifies  the  font for axis tick labels. The default is
-                     *-Courier-Bold-R-Normal-*-100-*.
-
-              <B>-ticklength</B> <I>pixels</I>
-                     Sets the length of major and minor ticks (minor ticks are
-                     half  the  length of major ticks). If <I>pixels</I> is less than
-                     zero, the axis will be inverted with ticks drawn pointing
-                     towards the plot.  The default is 0.1i.
-
-              <B>-title</B> <I>text</I>
-                     Sets  the title of the axis. If <I>text</I> is "", no axis title
-                     will be displayed.
-
-              <B>-titlecolor</B> <I>color</I>
-                     Sets the color of the axis title. The default is black.
-
-              <B>-titlefont</B> <I>fontName</I>
-                     Specifies the font for axis title. The default is  *-Hel-
-                     vetica-Bold-R-Normal-*-14-140-*.
-
-              Axis configuration options may be also be set by the <B>option</B> com-
-              mand.  The resource class is Axis.  The resource names  are  the
-              names  of  the  axes  (such  as  x  or  x2).   option  add *Bar-
-              chart.Axis.Color  blue  option  add  *Barchart.x.LogScale   true
-              option add *Barchart.x2.LogScale false
-
-       <I>pathName</I> <B>axis</B> <B>create</B> <I>axisName</I> ?<I>option</I> <I>value</I>?...
-              Creates  a  new  axis by the name <I>axisName</I>.  No axis by the same
-              name can already exist. <I>Option</I> and <I>value</I> are described in  above
-              in the axis <B>configure</B> operation.
-
-       <I>pathName</I> <B>axis</B> <B>delete</B> ?<I>axisName</I>?...
-              Deletes  the  named axes. An axis is not really deleted until it
-              is not longer in use, so it's safe to delete axes mapped to ele-
-              ments.
-
-       <I>pathName</I> <B>axis</B> <B>invtransform</B> <I>axisName</I> <I>value</I>
-              Performs the inverse transformation, changing the screen-coordi-
-              nate <I>value</I> to a graph-coordinate, mapping the  value  mapped  to
-              <I>axisName</I>.  Returns the graph-coordinate.
-
-       <I>pathName</I> <B>axis</B> <B>limits</B> <I>axisName</I>
-              Returns  a  list of the minimum and maximum limits for <I>axisName</I>.
-              The order of the list is min max.
-
-       <I>pathName</I> <B>axis</B> <B>names</B> ?<I>pattern</I>?...
-              Returns a list of axes matching zero or more  patterns.   If  no
-              <I>pattern</I> argument is give, the names of all axes are returned.
-
-       <I>pathName</I> <B>axis</B> <B>transform</B> <I>axisName</I> <I>value</I>
-              Transforms  the  coordinate <I>value</I> to a screen-coordinate by map-
-
-       right Y-axis.
-
-       They implicitly control the axis that is currently using to that  loca-
-       tion.  By default, <B>xaxis</B> uses the x axis, <B>yaxis</B> uses y, <B>x2axis</B> uses x2,
-       and <B>y2axis</B> uses y2.  These components can be  more  convenient  to  use
-       than  always  determining  what axes are current being displayed by the
-       graph.
-
-       The following operations are available for axes.  They  mirror  exactly
-       the operations of the <B>axis</B> component.  The <I>axis</I> argument must be <B>xaxis</B>,
-       <B>x2axis</B>, <B>yaxis</B>, or <B>y2axis</B>.

-
-       <I>pathName</I> <I>axis</I> <B>use</B> ?<I>axisName</I>?
-              Designates the axis <I>axisName</I> is to be displayed  at  this  loca-
-              tion.   <I>AxisName</I>  can not be already in use at another location.
-              This command returns the name of the axis currently  using  this
-              location.
-
-   <B>CROSSHAIRS</B> <B>COMPONENT</B>
-       Cross  hairs  consist  of  two intersecting lines (one vertical and one
-       horizontal) drawn completely across the plotting area.  They  are  used
-       to  position the mouse in relation to the coordinate axes.  Cross hairs
-       differ from line markers in that they are implemented using XOR drawing
-       primitives.  This means that they can be quickly drawn and erased with-
-       out redrawing the entire widget.
-
-       The following operations are available for cross hairs:
-

-<H2>ELEMENTS</H2><PRE>
-       A data element represents a set of data.  It contains x and  y  vectors
-       which  are  the coordinates of the data points.  Elements are displayed
-       as bars where the length of the bar is proportional to the ordinate  of
-       the data point.  Elements also control the appearance of the data, such
-       as the color, stipple, relief, etc.
-
-       When new data elements are created, they are automatically added  to  a
-       list  of  displayed elements.   The display list controls what elements
-       are drawn and in what order.
-
-       The following operations are available for elements.
-
-       <I>pathName</I> <B>element</B> <B>activate</B> <I>elemName</I> ?<I>index</I>?...
-              Specifies the data points of element <I>elemName</I> to be drawn  using
-              active  foreground  and background colors.  <I>ElemName</I> is the name
-              of the element and <I>index</I> is a number representing the  index  of
-              the  data  point. If no indices are present then all data points
-              become active.
-
-       <I>pathName</I> <B>element</B> <B>bind</B> <I>tagName</I> ?<I>sequence</I>?  ?<I>command</I>?
-              Associates <I>command</I> with <I>tagName</I> such  that  whenever  the  event
-              sequence  given by <I>sequence</I> occurs for an element with this tag,
-              <I>command</I> will be invoked.  The syntax is similar to the <B>bind</B> com-
-              mand except that it operates on graph elements, rather than wid-
-              gets. See the <B>bind</B> manual entry for complete details on <I>sequence</I>
-              and the substitutions performed on <I>command</I> before invoking it.
-
-
-       <I>pathName</I> <B>element</B> <B>closest</B> <I>x</I> <I>y</I> ?<I>option</I> <I>value</I>?... ?<I>elemName</I>?...
-              Finds  the data point representing the bar closest to the window
-              coordinates <I>x</I> and <I>y</I> in the element <I>elemName</I>.   <I>ElemName</I>  is  the
-              name  of  an  element, which must be currently displayed.  If no
-              elements  are  specified,  then  all  displayed   elements   are
-              searched.   It  returns  a key-value list containing the name of
-              the closest element, the index of its  closest  point,  and  the
-              graph-coordinates  of  the  point.  If  no data point within the
-              threshold distance can be found, "" is returned.  The  following
-              <I>option</I>-<I>value</I> pairs are available.
-
-              <B>-halo</B> <I>pixels</I>
-                     Specifies a threshold distance where selected data points
-                     are ignored.  <I>Pixels</I> is a valid screen distance, such  as
-                     2  or  1.2i.   If  this  option  isn't specified, then it
-                     defaults to the value of the <B>barchart</B>'s <B>-halo</B> option.
-
-       <I>pathName</I> <B>element</B> <B>configure</B> <I>elemName</I> ?<I>elemName</I>... ?<I>option</I> <I>value</I>?...
-              Queries or modifies  the  configuration  options  for  elements.
-              Several  elements  can  be  modified at the same time. If <I>option</I>
-              isn't specified, a list describing all the current  options  for
-              <I>elemName</I>  is  returned.   If <I>option</I> is specified, but not <I>value</I>,
-              then a list describing the option <I>option</I> is returned.  If one or
-              more  <I>option</I>  and <I>value</I> pairs are specified, then for each pair,
-              the element option  <I>option</I>  is  set  to  <I>value</I>.   The  following
-              options are valid for elements.
-
-              <B>-activepen</B> <I>penName</I>
-                     Specifies  pen to use to draw active element.  If <I>penName</I>
-                     is "", no active elements will be drawn.  The default  is
-                     activeLine.
-
-              <B>-bindtags</B> <I>tagList</I>
-                     Specifies the binding tags for the element.  <I>TagList</I> is a
-                     list of binding tag names.  The tags and their order will
-                     determine  how events for elements.  Each tag in the list
-                     matching the current event sequence  will  have  its  Tcl
-                     command  executed.  Implicitly the name of the element is
-                     always the first tag in the list.  The default  value  is
-                     all.
-
-              <B>-background</B> <I>color</I>
-                     Sets  the  the  color of the border around each bar.  The
-                     default is white.
-
-              <B>-barwidth</B> <I>value</I>
-                     Specifies the width  the  bars  drawn  for  the  element.
-                     <I>Value</I>  is  the  width  in  X-coordinates.  If this option
-                     isn't specified, the width of each bar is  the  value  of
-                     the widget's <B>-barwidth</B> option.
-
-                     a list of numeric expressions representing the X-Y  coor-

-              <B>-foreground</B> <I>color</I>
-                     Sets the color of the interior of the bars.
-
-              <B>-hide</B> <I>boolean</I>
-                     Indicates  whether the element is displayed.  The default
-                     is no.
-
-              <B>-label</B> <I>text</I>
-                     Sets the element's label in the legend.  If <I>text</I>  is  "",
-                     the  element  will  have  no  entry  in  the legend.  The
-                     default label is the element's name.
-
-              <B>-mapx</B> <I>xAxis</I>
-                     Selects the X-axis to  map  the  element's  X-coordinates
-                     onto.  <I>XAxis</I> must be the name of an axis.  The default is
-                     x.
-
-              <B>-mapy</B> <I>yAxis</I>
-                     Selects the Y-axis to  map  the  element's  Y-coordinates
-                     onto.   <I>YAxis</I> must be the name of an axis. The default is
-                     y.
-
-              <B>-relief</B> <I>string</I>
-                     Specifies the 3-D effect desired for bars.  <I>Relief</I>  indi-
-                     cates  how the interior of the bar should appear relative
-                     to the surface of the chart; for  example,  raised  means
-                     the bar should appear to protrude from the surface of the
-                     plotting area.  The default is raised.
-
-              <B>-stipple</B> <I>bitmap</I>
-                     Specifies a stipple pattern with which to draw the  bars.
-                     If  <I>bitmap</I>  is "", then the bar is drawn in a solid fash-
-                     ion.
-
-              <B>-xdata</B> <I>xVector</I>
-                     Specifies the x-coordinate vector of the  data.   <I>XVector</I>

-
-   <B>LEGEND</B> <B>COMPONENT</B>
-       The legend displays a list of the data elements.  Each  entry  consists
-       of the element's symbol and label.  The legend can appear in any margin
-       (the default location is in the right margin).  It can  also  be  posi-
-       tioned anywhere within the plotting area.
-
-       The following operations are valid for the legend.
-
-       <I>pathName</I> <B>legend</B> <B>activate</B> <I>pattern</I>...
-              Selects  legend entries to be drawn using the active legend col-
-              ors and relief.  All entries whose element names  match  <I>pattern</I>
-              are  selected.  To be selected, the element name must match only
-              one <I>pattern</I>.
-
-       <I>pathName</I> <B>legend</B> <B>bind</B> <I>tagName</I> ?<I>sequence</I>?  ?<I>command</I>?
-              Associates <I>command</I> with <I>tagName</I> such  that  whenever  the  event
-              sequence  given  by <I>sequence</I> occurs for a legend entry with this
-              tag, <I>command</I> will be invoked.  Implicitly the element  names  in
-              the  entry  are tags.  The syntax is similar to the <B>bind</B> command
-              except that it operates on legend entries, rather than  widgets.
-              See  the  <B>bind</B> manual entry for complete details on <I>sequence</I> and
-              the substitutions performed on <I>command</I> before invoking it.
-
-              If all arguments are specified then a new  binding  is  created,
-              replacing  any  existing  binding for the same <I>sequence</I> and <I>tag-</I>
-              <I>Name</I>.  If the first character of <I>command</I> is + then <I>command</I>  aug-
-              ments  an existing binding rather than replacing it.  If no <I>com-</I>
-              <I>mand</I> argument is provided then the command currently  associated
-              with  <I>tagName</I>  and  <I>sequence</I> (it's an error occurs if there's no
-              such binding) is returned.  If both  <I>command</I>  and  <I>sequence</I>  are
-              missing  then  a list of all the event sequences for which bind-
-              ings have been defined for <I>tagName</I>.
-
-              <B>-activebackground</B> <I>color</I>
-                     Sets the background color for active legend entries.  All
-                     legend  entries  marked  active  (see the legend <B>activate</B>
-                     operation) are drawn using this background color.
-
-              <B>-activeborderwidth</B> <I>pixels</I>
-                     Sets the width of the 3-D border around the outside  edge
-                     of the active legend entries.  The default is 2.
-
-              <B>-activeforeground</B> <I>color</I>
-                     Sets the foreground color for active legend entries.  All
-                     legend entries marked as active (see the legend  <B>activate</B>
-                     operation) are drawn using this foreground color.
-
-              <B>-activerelief</B> <I>relief</I>
-                     Specifies  the  3-D  effect  desired  for  active  legend
-                     entries.  <I>Relief</I> denotes how the interior  of  the  entry
-                     should appear relative to the legend; for example, raised
-                     means the entry should appear to protrude from  the  leg-
-                     end,  relative to the surface of the legend.  The default
-                     is flat.
-
-              <B>-anchor</B> <I>anchor</I>
-                     Tells how to position the legend relative  to  the  posi-
-                     tioning  point  for the legend.  This is dependent on the
-                     value of the <B>-position</B> option.  The default is center.
-
-                     left or right
-                                 The anchor describes how to position the leg-

-
-                     @x,y        The anchor specifies how to position the leg-
-                                 end  relative  to  the positioning point. For
-                                 example, if <I>anchor</I> is center then the  legend
-                                 is centered on the point; if <I>anchor</I> is n then
-                                 the legend will be drawn such  that  the  top
-                                 center  point of the rectangular region occu-
-                                 pied by the legend will be at the positioning
-                                 point.

-                                 end relative to the plotting area. For  exam-
-                                 ple,  if  <I>anchor</I> is center then the legend is
-                                 centered in the plotting area; if  <I>anchor</I>  is
-                                 ne  then  the  legend will be drawn such that
-                                 occupies the upper right corner of the  plot-
-                                 ting area.

-                     of  the legend (if such border is being drawn; the <B>relief</B>
-                     option determines this).  The default is 2 pixels.
-
-              <B>-font</B> <I>fontName</I>
-                     <I>FontName</I> specifies a font to use when drawing the  labels
-                     of  each  element into the legend.  The default is *-Hel-
-                     vetica-Bold-R-Normal-*-12-120-*.
-
-              <B>-foreground</B> <I>color</I>
-                     Sets the foreground color of the text drawn for the  ele-
-                     ment's label.  The default is black.
-
-              <B>-hide</B> <I>boolean</I>
-                     Indicates  whether  the  legend  should  be displayed. If
-                     <I>boolean</I> is true,  the  legend  will  not  be  draw.   The
-                     default is no.
-
-              <B>-ipadx</B> <I>pad</I>
-                     Sets  the  amount  of internal padding to be added to the
-                     width of each legend entry.  <I>Pad</I> can be a list of one  or
-                     two  screen distances.  If <I>pad</I> has two elements, the left
-                     side of the legend entry is padded by the first  distance
-                     and  the  right  side  by the second.  If <I>pad</I> is just one
-                     distance, both  the  left  and  right  sides  are  padded
-                     evenly.  The default is 2.
-
-              <B>-ipady</B> <I>pad</I>
-                     Sets  an  amount  of  internal padding to be added to the
-                     height of each legend entry.  <I>Pad</I> can be a list of one or
-                     two  screen  distances.  If <I>pad</I> has two elements, the top
-                     of the entry is padded by the first distance and the bot-
-                     tom by the second.  If <I>pad</I> is just one distance, both the
-                     top and bottom of  the  entry  are  padded  evenly.   The
-                     default is 2.
-
-              <B>-padx</B> <I>pad</I>
-                     Sets  the  padding to the left and right exteriors of the

-                     tances.   If  <I>pad</I>  has two elements, the left side of the
-                     legend is padded by the first distance and the right side
-                     by  the  second.   If <I>pad</I> has just one distance, both the
-                     left and right sides are padded evenly.  The  default  is
-                     4.
-
-              <B>-pady</B> <I>pad</I>
-                     Sets  the padding above and below the legend.  <I>Pad</I> can be
-                     a list of one or two screen distances.  If  <I>pad</I>  has  two
-                     elements,  the  area  above  the  legend is padded by the
-                     first distance and the area below by the second.  If  <I>pad</I>
-                     is  just  one distance, both the top and bottom areas are
-                     padded evenly.  The default is 0.
-
-                     drawn on top of any elements that  may  overlap  it.  The

-
-              <B>-relief</B> <I>relief</I>
-                     Specifies  the  3-D effect for the border around the leg-
-                     end.  <I>Relief</I> specifies how the  interior  of  the  legend
-                     should  appear  relative  to  the bar chart; for example,
-                     raised means the legend should appear  to  protrude  from
-                     the  bar chart, relative to the surface of the bar chart.
-                     The default is sunken.

-              Selects  legend entries to be drawn using the normal legend col-
-              ors and relief.  All entries whose element names  match  <I>pattern</I>
-              are  selected.  To be selected, the element name must match only

-       <I>pathName</I> <B>legend</B> <B>get</B> <I>pos</I>
-              Returns the name of the element whose entry  is  at  the  screen
-              position  <I>pos</I>  in  the  legend.  <I>Pos</I> must be in the form "<I>@x,y</I>",
-              where <I>x</I> and <I>y</I> are window coordinates.  If the given  coordinates
-              do not lie over a legend entry, "" is returned.
-
-   <B>PEN</B> <B>COMPONENTS</B>
-       Pens  define  attributes  for  elements.  Pens mirror the configuration
-       options of data elements that pertain to  how  symbols  and  lines  are
-       drawn.  Data elements use pens to determine how they are drawn.  A data
-       element may use several pens at once.  In this case, the pen used for a
-       particular  data  point is determined from each element's weight vector
-       (see the element's <B>-weight</B> and <B>-style</B> options).
-
-       One pen, called activeBar, is automatically created.  It's used as  the
-       default  active  pen  for  elements.  So  you  can  change  the  active
-       attributes for all elements by simply reconfiguring this pen.   .g  pen
-       configure  "activeBar" -fg green -bg green4 You can create and use sev-
-       eral pens. To create a pen, invoke the pen  component  and  its  create
-       operation.   .g  pen  create myPen You map pens to a data element using
-       either the element's <B>-pen</B> or <B>-activepen</B>  options.   .g  element  create
-       "e1" -xdata $x -ydata $tempData \
-           -pen myPen An element can use several pens at once. This is done by
-       specifying the name of the pen in the element's  style  list  (see  the
-       <B>-styles</B>  option).   .g element configure "e1" -styles { myPen 2.0 3.0 }
-       This says that any data point with a weight between 2.0 and 3.0  is  to
-       be drawn using the pen myPen.  All other points are drawn with the ele-
-       ment's default attributes.
-
-       The following operations are available for pen components.
-              <I>value</I>.  The following options are valid for pens.
-
-              <B>-background</B> <I>color</I>
-                     Sets the the color of the border around  each  bar.   The
-                     default is white.
-
-              <B>-borderwidth</B> <I>pixels</I>
-                     Sets  the border width of the 3-D border drawn around the
-                     outside of each bar.  The <B>-relief</B>  option  determines  if
-                     such  a  border  is drawn.  <I>Pixels</I> must be a valid screen
-                     distance like 2 or 0.25i. The default is 2.
-
-              <B>-foreground</B> <I>color</I>
-                     Sets the color of the interior of the bars.
-
-              <B>-relief</B> <I>string</I>
-                     Specifies the 3-D effect desired for bars.  <I>Relief</I>  indi-
-                     cates  how the interior of the bar should appear relative
-                     to the surface of the chart; for  example,  raised  means
-                     the  bar  should  appear  to protrude from the bar chart,
-                     relative to  the  surface  of  the  plotting  area.   The
-                     default is raised.
-
-              <B>-stipple</B> <I>bitmap</I>
-                     Specifies  a stipple pattern with which to draw the bars.
-                     If <I>bitmap</I> is "", then the bar is drawn in a  solid  fash-
-                     ion.
-
-              <B>-type</B> <I>elemType</I>
-                     Specifies the type of element the pen is to be used with.
-                     This option should only be  employed  when  creating  the
-                     pen.   This is for those that wish to mix different types
-                     of elements (bars and lines)  on  the  same  graph.   The
-                     default type is "bar".
-
-              Pen  configuration options may be also be set by the <B>option</B> com-
-              mand.  The resource class is Pen.  The resource  names  are  the
-              names  of  the  pens.   option add *Barchart.Pen.Foreground

-
-       <I>pathName</I> <B>pen</B> <B>create</B> <I>penName</I> ?<I>option</I> <I>value</I>?...
-              Creates a new pen by the name <I>penName</I>.  No pen by the same  name
-              can  already  exist.  <I>Option</I> and <I>value</I> are described in above in
-              the pen <B>configure</B> operation.
-
-       <I>pathName</I> <B>pen</B> <B>delete</B> ?<I>penName</I>?...
-              Deletes the named pens. A pen is not really deleted until it  is
-              not  longer  in  use, so it's safe to delete pens mapped to ele-
-              ments.
-
-       <I>pathName</I> <B>pen</B> <B>names</B> ?<I>pattern</I>?...
-              Returns a list of pens matching zero or more  patterns.   If  no
-              <I>option</I>.   <I>Option</I> may be any option described below for the post-
-              script <B>configure</B> operation.
-
-       <I>pathName</I> <B>postscript</B> <B>configure</B> ?<I>option</I> <I>value</I>?...
-              Queries or modifies the  configuration  options  for  PostScript
-              generation.   If  <I>option</I>  isn't specified, a list describing the
-              current postscript options for <I>pathName</I> is returned.  If  <I>option</I>
-              is  specified,  but  not <I>value</I>, then a list describing <I>option</I> is
-              returned.  If one or more <I>option</I> and <I>value</I> pairs are  specified,
-              then  for  each  pair,  the  postscript  option <I>option</I> is set to
-              <I>value</I>.  The following postscript options are available.
-
-              <B>-center</B> <I>boolean</I>
-                     Indicates whether the plot  should  be  centered  on  the
-                     PostScript  page.   If <I>boolean</I> is false, the plot will be
-                     placed in the upper left corner of the page.  The default
-                     is 1.
-
-              <B>-colormap</B> <I>varName</I>
-                     <I>VarName</I>  must be the name of a global array variable that
-                     specifies a color mapping from the X color name to  Post-
-                     Script.   Each  element  of <I>varName</I> must consist of Post-
-                     Script code to set a particular color value  (e.g.  ``1.0
-                     1.0  0.0  setrgbcolor'').  When generating color informa-
-                     tion in PostScript, the array variable <I>varName</I> is checked
-                     if  an element of the name as the color exists. If so, it
-                     uses its value as  the  PostScript  command  to  set  the
-                     color.  If this option hasn't been specified, or if there
-                     isn't an entry in <I>varName</I> for a given color, then it uses
-                     the red, green, and blue intensities from the X color.
-
-              <B>-colormode</B> <I>mode</I>
-                     Specifies  how to output color information.  <I>Mode</I> must be
-                     either color (for full color output), gray  (convert  all
-                     colors  to their gray-scale equivalents) or mono (convert
-                     foreground colors  to  black  and  background  colors  to
-                     white).  The default mode is color.
-
-              <B>-fontmap</B> <I>varName</I>
-                     <I>VarName</I>  must be the name of a global array variable that
-                     specifies a font mapping from the X font  name  to  Post-
-                     Script.   Each  element  of <I>varName</I> must consist of a Tcl
-                     list with one or two elements; the name and point size of
-                     a  PostScript  font.  When outputting PostScript commands
-                     for a particular font,  the  array  variable  <I>varName</I>  is
-                     checked  to  see  if  an  element  by  the specified font
-                     exists.  If there is  such  an  element,  then  the  font
-                     information  contained  in  that  element  is used in the
-                     PostScript output.  (If the point size  is  omitted  from
-                     the  list, the point size of the X font is used).  Other-
-                     wise the X font is examined in an attempt to  guess  what
-                     PostScript  font to use.  This works only for fonts whose
-                     widget's height.  The default is 0.
-
-              <B>-landscape</B> <I>boolean</I>
-                     If <I>boolean</I> is true, this specifies the printed area is to
-                     be  rotated 90 degrees.  In non-rotated output the X-axis
-                     of the printed area runs along the short dimension of the
-                     page  (``portrait''  orientation);  in rotated output the
-                     X-axis runs along the long dimension of the page (``land-
-                     scape'' orientation).  Defaults to 0.
-
-              <B>-maxpect</B> <I>boolean</I>
-                     Indicates  to  scale  the plot so that it fills the Post-
-                     Script page.  The aspect ratio of the barchart  is  still
-                     retained.  The default is 0.
-
-              <B>-padx</B> <I>pad</I>
-                     Sets  the  horizontal padding for the left and right page
-                     borders.  The borders are exterior to the plot.  <I>Pad</I>  can
-                     be a list of one or two screen distances.  If <I>pad</I> has two
-                     elements, the left border is padded by the first distance
-                     and  the right border by the second.  If <I>pad</I> has just one
-                     distance, both the left  and  right  borders  are  padded
-                     evenly.  The default is 1i.
-
-              <B>-pady</B> <I>pad</I>
-                     Sets  the  vertical  padding  for the top and bottom page
-                     borders. The borders are exterior to the plot.   <I>Pad</I>  can
-                     be a list of one or two screen distances.  If <I>pad</I> has two
-                     elements, the top border is padded by the first  distance
-                     and the bottom border by the second.  If <I>pad</I> has just one
-                     distance, both the top  and  bottom  borders  are  padded
-                     evenly.  The default is 1i.
-
-              <B>-paperheight</B> <I>pixels</I>
-                     Sets the height of the postscript page.  This can be used
-                     to select between different page sizes (letter, A4, etc).
-                     The default height is 11.0i.
-
-              <B>-paperwidth</B> <I>pixels</I>
-                     Sets  the width of the postscript page.  This can be used
-                     to select between different page sizes (letter, A4, etc).
-                     The default width is 8.5i.
-
-              <B>-width</B> <I>pixels</I>
-                     Sets  the  width  of  the plot.  This lets you generate a
-                     plot of a width different from that of  the  widget.   If
-                     <I>pixels</I> is 0, the width is the same as the widget's width.
-                     The default is 0.
-
-              Postscript configuration options may  be  also  be  set  by  the
-              <B>option</B>  command.  The resource name and class are postscript and
-              Postscript respectively.  option add  *Barchart.postscript.Deco-
-
-       with  a  particular  element, so that when the element is hidden or un-
-       hidden, so is the marker.  By  default,  markers  are  the  last  items
-       drawn,  so  that  data  elements  will  appear in behind them.  You can
-       change this by configuring the <B>-under</B> option.
-
-       Markers, in contrast to elements, don't affect the scaling of the coor-
-       dinate axes.  They can also have <I>elastic</I> coordinates (specified by -Inf
-       and Inf respectively) that translate into the minimum or maximum  limit
-       of  the axis.  For example, you can place a marker so it always remains
-       in the lower left corner of the plotting area, by using the coordinates
-       -Inf,-Inf.
-
-       The following operations are available for markers.
-
-       <I>pathName</I> <B>marker</B> <B>after</B> <I>markerId</I> ?<I>afterId</I>?
-              Changes the order of the markers, drawing the first marker after
-              the second.  If no second <I>afterId</I>  argument  is  specified,  the
-              marker  is  placed at the end of the display list.  This command
-              can be used to control how markers are displayed  since  markers
-              are drawn in the order of this display list.
-
-       <I>pathName</I> <B>marker</B> <B>before</B> <I>markerId</I> ?<I>beforeId</I>?
-              Changes  the  order  of  the  markers,  drawing the first marker
-              before the second.  If no second <I>beforeId</I> argument is specified,
-              the marker is placed at the beginning of the display list.  This
-              command can be used to control how markers are  displayed  since
-              markers are drawn in the order of this display list.
-
-       <I>pathName</I> <B>marker</B> <B>bind</B> <I>tagName</I> ?<I>sequence</I>?  ?<I>command</I>?
-              Associates  <I>command</I>  with  <I>tagName</I>  such that whenever the event
-              sequence given by <I>sequence</I> occurs for a marker  with  this  tag,
-              <I>command</I> will be invoked.  The syntax is similar to the <B>bind</B> com-
-              mand except that it operates on graph markers, rather than  wid-
-              gets. See the <B>bind</B> manual entry for complete details on <I>sequence</I>
-              and the substitutions performed on <I>command</I> before invoking it.
-
-              If all arguments are specified then a new  binding  is  created,
-              replacing  any  existing  binding for the same <I>sequence</I> and <I>tag-</I>
-              <I>Name</I>.  If the first character of <I>command</I> is + then <I>command</I>  aug-
-              ments  an existing binding rather than replacing it.  If no <I>com-</I>
-              <I>mand</I> argument is provided then the command currently  associated
-              with  <I>tagName</I>  and  <I>sequence</I> (it's an error occurs if there's no
-              such binding) is returned.  If both  <I>command</I>  and  <I>sequence</I>  are
-              missing  then  a list of all the event sequences for which bind-
-              ings have been defined for <I>tagName</I>.
-
-       <I>pathName</I> <B>marker</B> <B>cget</B> <I>option</I>
-              Returns the current value of  the  marker  configuration  option
-              given  by  <I>option</I>.   <I>Option</I> may be any option described below in
-              the <B>configure</B> operation.
-
-       <I>pathName</I> <B>marker</B> <B>configure</B> <I>markerId</I> ?<I>option</I> <I>value</I>?...
-                     determine  how  events for markers are handled.  Each tag
-                     in the list matching the current event sequence will have
-                     its  Tcl  command  executed.   Implicitly the name of the
-                     marker is always the first tag in the list.  The  default
-                     value is all.
-
-              <B>-coords</B> <I>coordList</I>
-                     Specifies  the coordinates of the marker.  <I>CoordList</I> is a
-                     list of graph-coordinates.   The  number  of  coordinates
-                     required  is  dependent  on  the  type  of marker.  Text,
-                     image, and window markers need only two  coordinates  (an
-                     X-Y  coordinate).   Bitmap markers can take either two or
-                     four coordinates (if four, they represent the corners  of
-                     the bitmap). Line markers need at least four coordinates,
-                     polygons at least six.  If <I>coordList</I> is  "",  the  marker
-                     will not be displayed.  The default is "".
-
-              <B>-element</B> <I>elemName</I>
-                     Links  the  marker with the element <I>elemName</I>.  The marker
-                     is drawn only if the element is also currently  displayed
-                     (see  the  element's <B>show</B> operation).  If <I>elemName</I> is "",
-                     the marker is always drawn.  The default is "".
-
-              <B>-hide</B> <I>boolean</I>
-                     Indicates whether the marker  is  drawn.  If  <I>boolean</I>  is
-                     true, the marker is not drawn.  The default is no.
-
-              <B>-mapx</B> <I>xAxis</I>
-                     Specifies  the  X-axis  to map the marker's X-coordinates
-                     onto.  <I>XAxis</I> must the name of an axis.  The default is x.
-
-              <B>-mapy</B> <I>yAxis</I>
-                     Specifies  the  Y-axis  to map the marker's Y-coordinates
-                     onto.  <I>YAxis</I> must the name of an axis.  The default is y.
-
-              <B>-name</B> <I>markerId</I>
-                     Changes  the  identifier  for the marker.  The identifier
-                     <I>markerId</I> can not already be used by another  marker.   If
-                     this   option  isn't  specified,  the  marker's  name  is
-                     uniquely generated.
-
-              <B>-under</B> <I>boolean</I>
-                     Indicates whether the marker is  drawn  below/above  data
-                     elements.   If  <I>boolean</I>  is  true, the marker is be drawn
-                     underneath the data elements.  Otherwise, the  marker  is
-                     drawn on top of the element.  The default is 0.
-
-              <B>-xoffset</B> <I>pixels</I>
-                     Specifies a screen distance to offset the marker horizon-
-                     tally.  <I>Pixels</I> is a valid screen distance, such as  2  or
-                     1.2i.  The default is 0.
-
-              Creates  a marker of the selected type. <I>Type</I> may be either text,
-              line, bitmap, image, polygon, or window.  This  command  returns
-              the  marker  identifier,  used  as  the <I>markerId</I> argument in the
-              other marker-related commands.  If the  <B>-name</B>  option  is  used,
-              this  overrides  the normal marker identifier.  If the name pro-
-              vided is already used for another marker, the  new  marker  will
-              replace the old.
-
-       <I>pathName</I> <B>marker</B> <B>delete</B> ?<I>name</I>?...
-              Removes  one  of  more markers.  The graph will automatically be
-              redrawn without the marker..
-
-       <I>pathName</I> <B>marker</B> <B>exists</B> <I>markerId</I>
-              Returns 1 if the marker <I>markerId</I> exists and 0 otherwise.
-
-       <I>pathName</I> <B>marker</B> <B>names</B> ?<I>pattern</I>?
-              Returns the names of all the markers that currently  exist.   If
-              <I>pattern</I>  is  supplied,  only  those markers whose names match it
-              will be returned.
-
-       <I>pathName</I> <B>marker</B> <B>type</B> <I>markerId</I>
-              Returns the type of the marker given by <I>markerId</I>, such  as  line
-              or  text.  If <I>markerId</I> is not a valid a marker identifier, "" is
-              returned.
-
-   <B>BITMAP</B> <B>MARKERS</B>
-       A bitmap marker displays a bitmap.  The size  of  the  bitmap  is  con-
-       trolled  by  the  number of coordinates specified.  If two coordinates,
-       they specify the position of the top-left corner of  the  bitmap.   The
-       bitmap  retains  its normal width and height.  If four coordinates, the
-       first and second pairs of coordinates represent the corners of the bit-
-       map.   The bitmap will be stretched or reduced as necessary to fit into
-       the bounding rectangle.
-
-       Bitmap markers are created with the marker's <B>create</B>  operation  in  the
-       form:  <I>pathName</I>  <B>marker</B>  <B>create</B>  <B>bitmap</B> ?<I>option</I> <I>value</I>?...  There may be
-       many <I>option</I>-<I>value</I> pairs, each sets  a  configuration  options  for  the
-       marker.   These  same  <I>option</I>-<I>value</I> pairs may be used with the marker's
-       <B>configure</B> operation.
-
-       The following options are specific to bitmap markers:
-
-       <B>-background</B> <I>color</I>
-              Same as the <B>-fill</B> option.
-
-       <B>-bitmap</B> <I>bitmap</I>
-              Specifies the bitmap to be displayed.   If  <I>bitmap</I>  is  "",  the
-              marker will not be displayed.  The default is "".
-
-       <B>-fill</B> <I>color</I>
-              Sets  the background color of the bitmap.  If <I>color</I> is the empty
-              string, no background will be transparent.   The  default  back-
-
-       <B>-rotate</B> <I>theta</I>
-              Sets  the rotation of the bitmap.  <I>Theta</I> is a real number repre-
-              senting the angle of rotation in degrees.  The marker  is  first
-              rotated  and  then placed according to its anchor position.  The
-              default rotation is 0.0.
-
-   <B>IMAGE</B> <B>MARKERS</B>
-       A image marker displays an image.  Image markers are created  with  the
-       marker's  <B>create</B>  operation  in  the form: <I>pathName</I> <B>marker</B> <B>create</B> <B>image</B>
-       ?<I>option</I> <I>value</I>?...  There may be many <I>option</I>-<I>value</I> pairs,  each  sets  a
-       configuration option for the marker.  These same <I>option</I>-<I>value</I> pairs may
-       be used with the marker's <B>configure</B> operation.
-
-       The following options are specific to image markers:
-
-       <B>-anchor</B> <I>anchor</I>
-              <I>Anchor</I> tells how to position the image relative to the position-
-              ing  point  for the image. For example, if <I>anchor</I> is center then
-              the image is centered on the point;  if <I>anchor</I>  is  n  then  the
-              image  will be drawn such that the top center point of the rect-
-              angular region occupied by the image will be at the  positioning
-              point.  This option defaults to center.
-
-       <B>-image</B> <I>image</I>
-              Specifies  the  image  to  be drawn.  If <I>image</I> is "", the marker
-              will not be drawn.  The default is "".
-
-   <B>LINE</B> <B>MARKERS</B>
-       A line marker displays one or more connected line segments.  Line mark-
-       ers  are  created  with marker's <B>create</B> operation in the form: <I>pathName</I>
-       <B>marker</B> <B>create</B> <B>line</B> ?<I>option</I> <I>value</I>?...  There may  be  many  <I>option</I>-<I>value</I>
-       pairs,  each  sets  a  configuration option for the marker.  These same
-       <I>option</I>-<I>value</I> pairs may be used with the marker's <B>configure</B> operation.
-
-       The following options are specific to line markers:
-
-       <B>-dashes</B> <I>dashList</I>
-              Sets the dash style of the line. <I>DashList</I> is a list of up to  11
-              numbers that alternately represent the lengths of the dashes and
-              gaps on the line.  Each number must be between 1  and  255.   If
-              <I>dashList</I> is "", the marker line will be solid.
-
-       <B>-fill</B> <I>color</I>
-              Sets  the background color of the line.  This color is used with
-              striped lines (see the <B>-dashes</B> option). If <I>color</I>  is  the  empty
-              string,  no  background color is drawn (the line will be dashed,
-              not striped).  The default background color is "".
-
-       <B>-linewidth</B> <I>pixels</I>
-              Sets the width of the lines.  The default width is 0.
-
-       in  the  form:  <I>pathName</I> <B>marker</B> <B>create</B> <B>polygon</B> ?<I>option</I> <I>value</I>?...  There
-       may be many <I>option</I>-<I>value</I> pairs, each sets a  configuration  option  for
-       the  marker.  These same <I>option</I>-<I>value</I> pairs may be used with the <B>marker</B>
-       <B>configure</B> command to change the marker's configuration.  The  following
-       options are supported for polygon markers:
-
-       <B>-dashes</B> <I>dashList</I>
-              Sets the dash style of the outline of the polygon. <I>DashList</I> is a
-              list of up to 11 numbers that alternately represent the  lengths
-              of  the  dashes  and  gaps  on the outline.  Each number must be
-              between 1 and 255. If <I>dashList</I> is "",  the  outline  will  be  a
-              solid line.
-
-       <B>-fill</B> <I>color</I>
-              Sets  the  fill  color of the polygon.  If <I>color</I> is "", then the
-              interior of the polygon is transparent.  The default is white.
-
-       <B>-linewidth</B> <I>pixels</I>
-              Sets the width of the outline of the polygon. If <I>pixels</I> is zero,
-              no outline is drawn. The default is 0.
-
-       <B>-outline</B> <I>color</I>
-              Sets the color of the outline of the polygon.  If the polygon is
-              stippled (see the <B>-stipple</B> option),  then  this  represents  the
-              foreground color of the stipple.  The default is black.
-
-       <B>-stipple</B> <I>bitmap</I>
-              Specifies  that the polygon should be drawn with a stippled pat-
-              tern rather than a solid color. <I>Bitmap</I> specifies a bitmap to use
-              as  the  stipple  pattern.  If <I>bitmap</I> is "", then the polygon is
-              filled with a solid color (if the <B>-fill</B>  option  is  set).   The
-              default is "".
-
-   <B>TEXT</B> <B>MARKERS</B>
-       A  text  marker displays a string of characters on one or more lines of
-       text.  Embedded newlines cause line breaks.  They may be used to  anno-
-       tate  regions  of  the graph.  Text markers are created with the <B>create</B>
-       operation in the form: <I>pathName</I> <B>marker</B> <B>create</B>  <B>text</B>  ?<I>option</I>  <I>value</I>?...
-       There  may be many <I>option</I>-<I>value</I> pairs, each sets a configuration option
-       for the text marker.  These same <I>option</I>-<I>value</I> pairs may  be  used  with
-       the marker's <B>configure</B> operation.
-
-       The following options are specific to text markers:
-
-       <B>-anchor</B> <I>anchor</I>
-              <I>Anchor</I>  tells how to position the text relative to the position-
-              ing point for the text. For example, if <I>anchor</I>  is  center  then
-              the  text is centered on the point; if <I>anchor</I> is n then the text
-              will be drawn such that the top center point of the  rectangular
-              region  occupied  by  the text will be at the positioning point.
-              This default is center.
-
-
-       <B>-justify</B> <I>justify</I>
-              Specifies  how  the text should be justified.  This matters only
-              when the marker contains more than one  line  of  text.  <I>Justify</I>
-              must be left, right, or center.  The default is center.
-
-       <B>-outline</B> <I>color</I>
-              Sets the color of the text. The default value is black.
-
-       <B>-padx</B> <I>pad</I>
-              Sets  the  padding  to the left and right exteriors of the text.
-              <I>Pad</I> can be a list of one or two screen distances.   If  <I>pad</I>  has
-              two  elements,  the left side of the text is padded by the first
-              distance and the right side by the second.  If <I>pad</I> has just  one
-              distance,  both the left and right sides are padded evenly.  The
-              default is 4.
-
-       <B>-pady</B> <I>pad</I>
-              Sets the padding above and below the text.  <I>Pad</I> can be a list of
-              one  or two screen distances.  If <I>pad</I> has two elements, the area
-              above the text is padded by the  first  distance  and  the  area
-              below  by the second.  If <I>pad</I> is just one distance, both the top
-              and bottom areas are padded evenly.  The default is 4.
-
-       <B>-rotate</B> <I>theta</I>
-              Specifies the number of degrees to rotate the text.  <I>Theta</I> is  a
-              real  number  representing the angle of rotation.  The marker is
-              first rotated along its center and is then  drawn  according  to
-              its anchor position. The default is 0.0.
-
-       <B>-text</B> <I>text</I>
-              Specifies  the  text  of  the marker.  The exact way the text is
-              displayed may be affected by other options such  as  <B>-anchor</B>  or
-              <B>-rotate</B>.
-
-   <B>WINDOW</B> <B>MARKERS</B>
-       A  window marker displays a widget at a given position.  Window markers
-       are created with the marker's <B>create</B> operation in  the  form:  <I>pathName</I>
-       <B>marker</B>  <B>create</B> <B>window</B> ?<I>option</I> <I>value</I>?...  There may be many <I>option</I>-<I>value</I>
-       pairs, each sets a configuration option for  the  marker.   These  same
-       <I>option</I>-<I>value</I> pairs may be used with the marker's <B>configure</B> command.
-
-       The following options are specific to window markers:
-
-       <B>-anchor</B> <I>anchor</I>
-              <I>Anchor</I>  tells  how  to position the widget relative to the posi-
-              tioning point for the widget. For example, if <I>anchor</I>  is  center
-              then  the  widget  is centered on the point; if <I>anchor</I> is n then
-              the widget will be displayed such that the top center  point  of
-              the  rectangular  region  occupied  by the widget will be at the
-              positioning point.  This option defaults to center.

-<H2>GRAPH COMPONENT BINDINGS</H2><PRE>
-       Specific barchart components, such  as  elements,  markers  and  legend
-       entries,  can  have  a  command trigger when event occurs in them, much
-       like canvas items in Tk's canvas widget.  Not all event  sequences  are
-       valid.  The only binding events that may be specified are those related
-       to the mouse and keyboard (such as <B>Enter</B>, <B>Leave</B>,  <B>ButtonPress</B>,  <B>Motion</B>,
-       and <B>KeyPress</B>).
-
-       Only  one element or marker can be picked during an event.  This means,
-       that if the mouse is directly over both an element and a  marker,  only
-       the  uppermost  component  is  selected.   This  isn't  true for legend
-       entries.  Both a legend entry and an element (or marker)  binding  com-
-       mands will be invoked if both items are picked.
-
-       It is possible for multiple bindings to match a particular event.  This
-       could occur, for example, if one binding is associated with the element
-       name  and another is associated with one of the element's tags (see the
-       <B>-bindtags</B> option).  When this occurs, all of the matching bindings  are
-       invoked.   A binding associated with the element name is invoked first,
-       followed by one binding for each of the element's bindtags.   If  there
-       are  multiple  matching  bindings  for a single tag, then only the most
-       specific binding is invoked.  A continue command in  a  binding  script
-       terminates  that script, and a break command terminates that script and
-       skips any remaining scripts for the event, just as for  the  bind  com-
-       mand.
-
-       The  <B>-bindtags</B>  option for these components controls addition tag names
-       which can be matched.  Implicitly elements and markers always have tags
-       matching  their  names.   Setting  the  value  of  the <B>-bindtags</B> option
-       doesn't change this.
-
-
-</PRE>
-<H2>C LANGUAGE API</H2><PRE>
-       You can manipulate data elements from the C  language.   There  may  be
-       situations  where it is too expensive to translate the data values from
-       ASCII strings.  Or you might want to read data in a special  file  for-
-       mat.
-
-       Data  can manipulated from the C language using BLT vectors.  You spec-
-       ify the X-Y data coordinates of an element as  vectors  and  manipulate
-       the  vector  from  C.  The barchart will be redrawn automatically after
-       the vectors are updated.
-
-       From Tcl, create the vectors and configure the  element  to  use  them.
-       vector  X  Y  .g  element configure line1 -xdata X -ydata Y To set data
-       points from C, you pass the values  as  arrays  of  doubles  using  the
-       <B>Blt_ResetVector</B> call.  The vector is reset with the new data and at the
-       next idle point (when Tk re-enters its event loop), the graph  will  be
-       redrawn automatically.  #include &lt;tcl.h&gt; #include &lt;blt.h&gt;
-
-       register int i; Blt_Vector *xVec, *yVec; double x[50], y[50];
-
-       /*  Get  the  BLT  vectors  "X"  and "Y" (created above from Tcl) */ if
-       There may be cases where the bar chart needs to be drawn and updated as
-       quickly as possible.  If drawing speed becomes a big problem, here  are
-       a few tips to speed up displays.
-
-       <B>o</B> Try  to  minimize  the  number  of data points.  The more data points
-         looked at, the more work the bar chart must do.
-
-       <B>o</B> If your data is generated as floating point values, the time required
-         to  convert the data values to and from ASCII strings can be signifi-
-         cant, especially when there any many data points.  You can avoid  the
-         redundant  string-to-decimal  conversions using the C API to BLT vec-
-         tors.
-
-       <B>o</B> Don't stipple or dash the element.  Solid bars are much faster.
-
-       <B>o</B> If you update data elements frequently, try turning off the  widget's
-         <B>-bufferelements</B>  option.   When  the bar chart is first displayed, it
-         draws data elements into an internal pixmap.  The pixmap  acts  as  a
-         cache,  so that when the bar chart needs to be redrawn again, and the
-         data elements or coordinate axes haven't changed, the pixmap is  sim-
-         ply  copied  to  the  screen.  This is especially useful when you are
-         using markers to highlight points and regions on the bar chart.   But
-         if  the  bar chart is updated frequently, changing either the element
-         data or coordinate axes, the buffering becomes redundant.
-
-
-</PRE>
-<H2>LIMITATIONS</H2><PRE>
-       Auto-scale routines do not use requested min/max limits  as  boundaries
-       when the axis is logarithmically scaled.
-
-       The PostScript output generated for polygons with more than 1500 points
-       may exceed the limits of some printers (See PostScript Language  Refer-
-       ence  Manual,  page 568).  The work-around is to break the polygon into
-       separate pieces.

-.SH NAME
-barchart \-  Bar chart for plotting X-Y coordinate data.
-.SH SYNOPSIS
-\fBbarchart\fI \fIpathName \fR?\fIoption value\fR?...
-.BE
-.SH DESCRIPTION
-The \fBbarchart\fR command creates a bar chart for plotting
-two-dimensional data (X-Y coordinates). A bar chart is a graphic means
-of comparing numbers by displaying bars of lengths proportional to the
-y-coordinates of the points they represented.  The bar chart has many
-configurable components: coordinate axes, elements, legend, grid
-lines, cross hairs, etc.  They allow you to customize the look and
-feel of the graph.
-.SH INTRODUCTION
-The \fBbarchart\fR command creates a new window for plotting
-two-dimensional data (X-Y coordinates), using bars of
-various lengths to represent the data points.  The bars are drawn in a
-rectangular area displayed in the center of the new window.  This is the
-\fIplotting area\fR.  The coordinate axes are drawn in
-the margins surrounding the plotting area.  By default, the legend is
-drawn in the right margin.  The title is displayed in top margin.
-.PP
-A \fBbarchart\fR widget has several configurable components:
-coordinate axes, data elements, legend, grid, cross hairs, pens,
-postscript, and annotation markers.  Each component can be queried or
-modified.
-.TP 1i
-\f(CWaxis\fR 
-
-Up to four coordinate axes (two X\-coordinate and two Y\-coordinate
-axes) can be displayed, but you can create and use any number of
-axes. Axes control what region of data is displayed and how the data
-is scaled. Each axis consists of the axis line, title, major and minor
-ticks, and tick labels. Tick labels display the value at each major
-tick.
-.TP 1i
-\f(CWcrosshairs\fR 
-Cross hairs are used to position the mouse pointer relative to the X
-and Y coordinate axes. Two perpendicular lines, intersecting at the
-current location of the mouse, extend across the plotting area to the
-coordinate axes.
-.TP 1i
-\f(CWelement\fR 
-An element represents a set of data to be plotted.  It contains an x
-and y vector of values representing the data points.  Each
-data point is displayed as a bar where the length of the bar is
-proportional to the ordinate (Y-coordinate) of the data point.
-The appearance of the bar, such as its color, stipple, or relief
-is configurable.
-.sp
-A special case exists when two or more data points have the same
-abscissa (X-coordinate).  By default, the bars are overlayed, one on
-top of the other.  The bars are drawn in the order of the element
-display list.  But you can also configure the bars to be displayed in
-two other ways.  They may be displayed as a stack, where each bar
-(with the same abscissa) is stacked on the previous.  Or they can be
-drawn side-by-side as thin bars.  The width of each bar is a function
-of the number of data points with the same abscissa.
-.TP 1i
-\f(CWgrid\fR
-Extends the major and minor ticks of the X\-axis and/or Y\-axis across the 
-plotting area. 
-.TP 1i
-\f(CWlegend\fR 
-The legend displays the name and symbol of each data element. 
-The legend can be drawn in any margin or in the plotting area.
-.TP 1i
-\f(CWmarker\fR
-Markers are used annotate or highlight areas of the graph. For
-example, you could use a text marker to label a particular data
-point. Markers come in various forms: text strings, bitmaps, connected
-line segments, images, polygons, or embedded widgets.
-.TP 1i
-\f(CWpen\fR 
-Pens define attributes for elements.  Data elements use pens to
-specify how they should be drawn.  A data element may use many pens at
-once.  Here the particular pen used for a data point is determined
-from each element's weight vector (see the element's \fB\-weight\fR
-and \fB\-style\fR options).
-.TP 1i
-\f(CWpostscript\fR
-The widget can generate encapsulated PostScript output. This component
-has several options to configure how the PostScript is generated.
-.SH SYNTAX
-.DS
-\fBbarchart \fIpathName \fR?\fIoption value\fR?...
-.DE
-The \fBbarchart\fR command creates a new window \fIpathName\fR and makes
-it into a \fBbarchart\fR widget.  At the time this command is invoked, there
-must not exist a window named \fIpathName\fR, but \fIpathName\fR's
-parent must exist.  Additional options may be specified on the
-command line or in the option database to configure aspects of the
-graph such as its colors and font.  See the \fBconfigure\fR operation
-below for the exact details about what \fIoption\fR and \fIvalue\fR
-pairs are valid.
-.PP
-If successful, \fBbarchart\fR returns the path name of the widget.  It
-also creates a new Tcl command by the same name.  You can use this
-command to invoke various operations that query or modify the graph.
-The general form is:
-.DS
-\fIpathName \fIoperation\fR \fR?\fIarg\fR?...
-.DE
-Both \fIoperation\fR and its arguments determine the exact behavior of
-the command.  The operations available for the graph are described in 
-the 
-.SB "BARCHART OPERATIONS"
-section.
-.PP
-The command can also be used to access components of the graph.
-.DS
-\fIpathName component operation\fR ?\fIarg\fR?...
-.DE
-The operation, now located after the name of the component, is the
-function to be performed on that component. Each component has its own
-set of operations that manipulate that component.  They will be
-described below in their own sections.
-.SH EXAMPLE
-The \fBbarchart\fR command creates a new bar chart.  
-.CS
-# Create a new bar chart.  Plotting area is black.
-barchart .b -plotbackground black
-.CE
-A new Tcl command \f(CW.b\fR is created.  This command can be used
-to query and modify the bar chart.  For
-example, to change the title of the graph to "My Plot", you use the
-new command and the \fBconfigure\fR operation.
-.CS
-# Change the title.
-\&.b configure -title "My Plot"
-.CE
-To add data elements, you use the command and the \fBelement\fR component.
-.CS
-# Create a new element named "e1"
-\&.b element create e1 \\
-	-xdata { 1 2 3 4 5 6 7 8 9 10 } \\
-	-ydata { 26.18 50.46 72.85 93.31 111.86 128.47 143.14 
-		155.85 166.60 175.38 }
-.CE
-The element's X-Y coordinates are specified using lists of
-numbers.  Alternately, BLT vectors could be used to hold the X-Y
-coordinates.
-.CS
-# Create two vectors and add them to the barchart.
-vector xVector yVector
-xVector set { 1 2 3 4 5 6 7 8 9 10 }
-yVector set { 26.18 50.46 72.85 93.31 111.86 128.47 143.14 155.85 
-	166.60 175.38 }
-\&n.b element create e1 -xdata xVector -ydata yVector
-.CE
-The advantage of using vectors is that when you modify one, the graph
-is automatically redrawn to reflect the new values.
-.CS
-# Change the y coordinate of the first point.
-set yVector(0) 25.18
-.CE
-An element named \f(CWe1\fR is now created in \f(CW.b\fR.  It 
-is automatically added to the display list of elements.  You can
-use this list to control in what order elements are displayed.
-To query or reset the element display list, you use the element's 
-\fBshow\fR operation.
-.CS
-# Get the current display list 
-set elemList [.b element show]
-# Remove the first element so it won't be displayed.
-\&.b element show [lrange $elemList 0 end]
-.CE
-The element will be displayed by as many bars as there are data points
-(in this case there are ten).  The bars will be drawn centered at the
-x-coordinate of the data point.  All the bars will have the same
-attributes (colors, stipple, etc).  The width of each bar is by
-default one unit.  You can change this with using the \fB\-barwidth\fR
-option.
-.CS
-# Change the scale of the x-coordinate data 
-xVector set { 0.2 0.4 0.6 0.8 1.0 1.2 1.4 1.6 1.8 2.0 }
-# Make sure we change the bar width too.
-\&.b configure -barwidth 0.2
-.CE
-The height of each bar is proportional to the ordinate (Y-coordinate)
-of the data point.
-.PP
-If two or more data points have the same abscissa (X-coordinate
-value), the bars representing those data points may be drawn in 
-various ways.
-The default is to overlay the bars, one on top of the other.
-The ordering is determined from the of element display list.  If
-the stacked mode is selected (using the \fB\-barmode\fR configuration
-option), the bars are stacked, each bar above the previous.
-.CS
-# Display the elements as stacked.
-\&.b configure -barmode stacked
-.CE
-If the aligned mode is selected, the bars having the same
-x-coordinates are displayed side by side.  The width of each bar is a
-fraction of its normal width, based upon the number of bars with the
-same x-coordinate.
-.CS
-# Display the elements side-by-side.
-\&.b configure -barmode aligned
-.CE
-By default, the element's label in the legend will be also
-\f(CWe1\fR.  You can change the label, or specify no legend entry,
-again using the element's \fBconfigure\fR operation.
-.CS
-# Don't display "e1" in the legend.
-\&.b element configure e1 -label ""
-.CE
-You can configure more than just the element's label.  An element has
-many attributes such as stipple, foreground and background colors,
-relief, etc.
-.CS
-\&.b element configure e1 -fg red -bg pink \\
-	-stipple gray50
-.CE
-Four coordinate axes are automatically created: \f(CWx\fR, \f(CWx2\fR,
-\f(CWy\fR, and \f(CWy2\fR.  And by default, elements are mapped onto the
-axes \f(CWx\fR and \f(CWy\fR.  This can be changed with the \fB\-mapx\fR
-and \fB\-mapy\fR options.
-.CS
-# Map "e1" on the alternate y axis "y2".
-\&.b element configure e1 -mapy y2
-.CE
-Axes can be configured in many ways too.  For example, you change the
-scale of the Y\-axis from linear to log using the \fBaxis\fR component.
-.CS
-# Y-axis is log scale.
-\&.b axis configure y -logscale yes
-.CE
-One important way axes are used is to zoom in on a particular data
-region.  Zooming is done by simply specifying new axis limits using
-the \fB\-min\fR and \fB\-max\fR configuration options.
-.CS
-\&.b axis configure x \-min 1.0 \-max 1.5
-\&.b axis configure y \-min 12.0 \-max 55.15
-.CE
-To zoom interactively, you link the\fBaxis configure\fR operations with
-some user interaction (such as pressing the mouse button), using the
-\fBbind\fR command.  To convert between screen and graph coordinates,
-use the \fBinvtransform\fR operation.
-.CS
-# Click the button to set a new minimum 
-bind .b <ButtonPress-1> { 
-    %W axis configure x \-min [%W axis invtransform x %x]
-    %W axis configure x \-min [%W axis invtransform x %y]
-}
-.CE
-By default, the limits of the axis are determined from data values.
-To reset back to the default limits, set the \fB\-min\fR and
-\fB\-max\fR options to the empty value.
-.CS
-# Reset the axes to autoscale again.
-\&.b axis configure x \-min {} \-max {}
-\&.b axis configure y \-min {} \-max {}
-.CE
-By default, the legend is drawn in the right margin.  You can
-change this or any legend configuration options using the
-\fBlegend\fR component.
-.CS
-# Configure the legend font, color, and relief
-\&.b legend configure -position left -relief raised \\
-	-font fixed -fg blue
-.CE
-To prevent the legend from being displayed, turn on the \fB\-hide\fR
-option.
-.CS
-# Don't display the legend.
-\&.b legend configure \-hide yes\fR
-.CE
-The \fBbarchart\fR has simple drawing procedures called markers.  They can be
-used to highlight or annotate data in the graph. The types of markers
-available are bitmaps, polygons, lines, or windows.  Markers can be
-used, for example, to mark or brush points.  For example there may be
-a line marker which indicates some low-water value.  Markers are created
-using the \fBmarker\fR operation.
-.CS
-# Create a line represent the low water mark at 10.0
-\&.b marker create line -name "low_water" \\
-	-coords { -Inf 10.0 Inf 10.0 } \\
-	-dashes { 2 4 2 } -fg red -bg blue 
-.CE
-This creates a line marker named \f(CWlow_water\fR.  It will display a
-horizontal line stretching across the plotting area at the
-y-coordinate 10.0.  The coordinates "-Inf" and "Inf" indicate the
-relative minimum and maximum of the axis (in this case the x-axis).  By
-default, markers are drawn last, on top of the bars.  You can change this
-with the \fB\-under\fR option.
-.CS
-# Draw the marker before elements are drawn.
-\&.b marker configure low_water -under yes

-You can add cross hairs or grid lines using the \fBcrosshairs\fR and
-\fBgrid\fR components.
-.CS
-# Display both cross hairs and grid lines.
-\&.b crosshairs configure -hide no -color red

-component.
-.CS
-# Print the bar chart into file "file.ps"
-\&.b postscript output file.ps -maxpect yes -decorations no
-.CE
-This generates a file \f(CWfile.ps\fR containing the encapsulated
-PostScript of the graph.  The option \fB\-maxpect\fR says to scale the
-plot to the size of the page.  Turning off the \fB\-decorations\fR
-option denotes that no borders or color backgrounds should be
-drawn (i.e. the background of the margins, legend, and plotting
-area will be white).

-.SH "BARCHART COMPONENTS"
-A graph is composed of several components: coordinate axes, data
-elements, legend, grid, cross hairs, postscript, and annotation
-markers. Instead of one big set of configuration options and
-operations, the graph is partitioned, where each component has its own
-configuration options and operations that specifically control that
-aspect or part of the graph. 
-.SS "AXIS COMPONENTS"
-Four coordinate axes are automatically created: two X\-coordinate axes
-(\f(CWx\fR and \f(CWx2\fR) and two Y\-coordinate axes (\f(CWy\fR, and
-\f(CWy2\fR).  By default, the axis \f(CWx\fR is located in the bottom
-margin, \f(CWy\fR in the left margin, \f(CWx2\fR in the top margin, and
-\f(CWy2\fR in the right margin.
-.PP
-An axis consists of the axis line, title, major and minor ticks, and
-tick labels.  Major ticks are drawn at uniform intervals along the
-axis.  Each tick is labeled with its coordinate value.  Minor ticks
-are drawn at uniform intervals within major ticks.  
-.PP
-The range of the axis controls what region of data is plotted.
-Data points outside the minimum and maximum limits of the axis are
-not plotted.  By default, the minimum and maximum limits are
-determined from the data, but you can reset either limit.
-.PP
-You can create and use several axes. To create an axis, invoke
-the axis component and its create operation.
-.CS
-# Create a new axis called "temperature"
-\&.b axis create temperature
-.CE
-You map data elements to an axis using the element's \-mapy and \-mapx
-configuration options. They specify the coordinate axes an element
-is mapped onto.
-.CS
-# Now map the temperature data to this axis.
-\&.b element create "temp" \-xdata $x \-ydata $tempData \\
-    \-mapy temperature
-.CE
-While you can have many axes, only four axes can be displayed
-simultaneously.  They are drawn in each of the margins surrounding
-the plotting area.  The axes \f(CWx\fR and \f(CWy\fR are drawn in the
-bottom and left margins. The axes \f(CWx2\fR and \f(CWy2\fR are drawn in
-top and right margins.  Only \f(CWx\fR and \f(CWy\fR are shown by
-default. Note that the axes can have different scales.
-.PP
-To display a different axis, you invoke one of the following
-components: \fBxaxis\fR, \fByaxis\fR, \fBx2axis\fR, and \fBy2axis\fR.
-The \fBuse\fR operation designates the axis to be drawn in the
-corresponding margin: \fBxaxis\fR in the bottom, \fByaxis\fR in the left, 
-\fBx2axis\fR in the top, and \fBy2axis\fR in the right.
-.CS
-# Display the axis temperature in the left margin.
-\&.b yaxis use temperature
-.CE
-.PP
-You can configure axes in many ways. The axis scale can be linear or
-logarithmic.  The values along the axis can either monotonically
-increase or decrease.  If you need custom tick labels, you can specify
-a Tcl procedure to format the label any way you wish.  You can
-control how ticks are drawn, by changing the major tick interval
-or the number of minor ticks.  You can define non-uniform tick intervals,
-such as for time-series plots.

-information contained in that element is used in the PostScript
-output.  (If the point size is omitted from the list, the point size
-of the X font is used).  Otherwise the X font is examined in an
-attempt to guess what PostScript font to use.  This works only for

-If \fIimage\fR is \f(CW""\fR, the marker will not be
-drawn.  The default is \f(CW""\fR.
-.SS "LINE MARKERS"
-A line marker displays one or more connected line segments.
-Line markers are created with marker's \fBcreate\fR operation in the form:
-.DS
-\fIpathName \fBmarker create line \fR?\fIoption value\fR?...
-.DE
-There may be many \fIoption\fR-\fIvalue\fR
-pairs, each sets a configuration option
-for the marker.  These same \fIoption\fR-\fIvalue\fR pairs may be
-used with the marker's \fBconfigure\fR operation.
-.PP
-The following options are specific to line markers:
-.TP
-\fB\-dashes \fIdashList\fR
-Sets the dash style of the line. \fIDashList\fR is a list of up to 11
-numbers that alternately represent the lengths of the dashes and gaps
-on the line.  Each number must be between 1 and 255.  If
-\fIdashList\fR is \f(CW""\fR, the marker line will be solid.
-.TP
-\fB\-fill \fIcolor\fR
-Sets the background color of the line.  This color is used with
-striped lines (see the \fB\-dashes\fR option). If \fIcolor\fR is
-the empty string, no background color is drawn (the line will be
-dashed, not striped).  The default background color is \f(CW""\fR.
-.TP
-\fB\-linewidth \fIpixels\fR
-Sets the width of the lines.
-The default width is \f(CW0\fR.
-.TP
-\fB\-outline \fIcolor\fR
-Sets the foreground color of the line. The default value is \f(CWblack\fR.
-.TP
-\fB\-stipple \fIbitmap\fR
-Specifies a stipple pattern used to draw the line, rather than
-a solid line.
-\fIBitmap\fR specifies a bitmap to use as the stipple
-pattern.  If \fIbitmap\fR is \f(CW""\fR, then the
-line is drawn in a solid fashion. The default is \f(CW""\fR.
-.SS "POLYGON MARKERS"
-A polygon marker displays a closed region described as two or more
-connected line segments.  It is assumed the first and
-last points are connected.  Polygon markers are created using the
-marker \fBcreate\fR operation in the form:
-.DS
-\fIpathName \fBmarker create polygon \fR?\fIoption value\fR?...
-.DE
-There may be many \fIoption\fR-\fIvalue\fR
-pairs, each sets a configuration option
-for the marker.  These same \fIoption\fR\-\fIvalue\fR pairs may be
-used with the \fBmarker configure\fR command to change the marker's
-configuration.
-The following options are supported for polygon markers:
-.TP
-\fB\-dashes \fIdashList\fR
-Sets the dash style of the outline of the polygon. \fIDashList\fR is a
-list of up to 11 numbers that alternately represent the lengths of
-the dashes and gaps on the outline.  Each number must be between 1 and
-255. If \fIdashList\fR is \f(CW""\fR, the outline will be a solid line.
-.TP
-\fB\-fill \fIcolor\fR
-Sets the fill color of the polygon.  If \fIcolor\fR is \f(CW""\fR, then
-the interior of the polygon is transparent.
-The default is \f(CWwhite\fR.
-.TP
-\fB\-linewidth \fIpixels\fR
-Sets the width of the outline of the polygon. If \fIpixels\fR is zero, 
-no outline is drawn. The default is \f(CW0\fR.
-.TP
-\fB\-outline \fIcolor\fR
-Sets the color of the outline of the polygon.  If the polygon is
-stippled (see the \fB\-stipple\fR option), then this represents the
-foreground color of the stipple.  The default is \f(CWblack\fR.
-.TP
-\fB\-stipple \fIbitmap\fR
-Specifies that the polygon should be drawn with a stippled pattern
-rather than a solid color. \fIBitmap\fR specifies a bitmap to use as
-the stipple pattern.  If \fIbitmap\fR is \f(CW""\fR, then the polygon is
-filled with a solid color (if the \fB\-fill\fR option is set).  The
-default is \f(CW""\fR.
-.SS "TEXT MARKERS"
-A text marker displays a string of characters on one or more lines of
-text.  Embedded newlines cause line breaks.  They may be used to
-annotate regions of the graph.  Text markers are created with the
-\fBcreate\fR operation in the form:
-.DS
-\fIpathName \fBmarker create text \fR?\fIoption value\fR?...
-.DE
-There may be many \fIoption\fR-\fIvalue\fR pairs, 
-each sets a configuration option for the text marker.  
-These same \fIoption\fR\-\fIvalue\fR pairs may be used with the 
-marker's \fBconfigure\fR operation.  
-.PP
-The following options are specific to text markers:
-.TP
-\fB\-anchor \fIanchor\fR
-\fIAnchor\fR tells how to position the text relative to the
-positioning point for the text. For example, if \fIanchor\fR is
-\f(CWcenter\fR then the text is centered on the point; if
-\fIanchor\fR is \f(CWn\fR then the text will be drawn such that the
-top center point of the rectangular region occupied by the text will
-be at the positioning point.  This default is \f(CWcenter\fR.
-.TP
-\fB\-background \fIcolor\fR
-Same as the \fB\-fill\fR option.
-.TP
-\fB\-font \fIfontName\fR
-Specifies the font of the text.  The default is
-\f(CW*-Helvetica-Bold-R-Normal-*-120-*\fR.
-.TP
-\fB\-fill \fIcolor\fR
-Sets the background color of the text.  If \fIcolor\fR is the empty
-string, no background will be transparent.  The default background color is
-\f(CW""\fR.
-.TP
-\fB\-foreground \fIcolor\fR
-Same as the \fB\-outline\fR option.
-.TP
-\fB\-justify \fIjustify\fR
-Specifies how the text should be justified.  This matters only when
-the marker contains more than one line of text. \fIJustify\fR must be
-\f(CWleft\fR, \f(CWright\fR, or \f(CWcenter\fR.  The default is
-\f(CWcenter\fR.
-.TP
-\fB\-outline \fIcolor\fR
-Sets the color of the text. The default value is \f(CWblack\fR.
-.TP
-\fB\-padx \fIpad\fR
-Sets the padding to the left and right exteriors of the text.
-\fIPad\fR can be a list of one or two screen distances.  If \fIpad\fR
-has two elements, the left side of the text is padded by the first
-distance and the right side by the second.  If \fIpad\fR has just one
-distance, both the left and right sides are padded evenly.  The
-default is \f(CW4\fR.
-.TP
-\fB\-pady \fIpad\fR
-Sets the padding above and below the text.  \fIPad\fR can be a list of
-one or two screen distances.  If \fIpad\fR has two elements, the area above the
-text is padded by the first distance and the area below by the second.
-If \fIpad\fR is just one distance, both the top and bottom areas
-are padded evenly.  The default is \f(CW4\fR.
-.TP
-\fB\-rotate \fItheta\fR
-Specifies the number of degrees to rotate the text.  \fITheta\fR is a
-real number representing the angle of rotation.  The marker is first
-rotated along its center and is then drawn according to its anchor
-position. The default is \f(CW0.0\fR.
-.TP
-\fB\-text \fItext\fR
-Specifies the text of the marker.  The exact way the text is
-displayed may be affected by other options such as \fB\-anchor\fR or
-\fB\-rotate\fR.
-.SS "WINDOW MARKERS"
-A window marker displays a widget at a given position.
-Window markers are created with the marker's \fBcreate\fR operation in
-the form:
-.DS
-\fIpathName \fBmarker create window \fR?\fIoption value\fR?...
-.DE
-There may be many \fIoption\fR-\fIvalue\fR
-pairs, each sets a configuration option
-for the marker.  These same \fIoption\fR\-\fIvalue\fR pairs may be
-used with the marker's \fBconfigure\fR command.
-.PP
-The following options are specific to window markers:
-.TP
-\fB\-anchor \fIanchor\fR
-\fIAnchor\fR tells how to position the widget relative to the
-positioning point for the widget. For example, if \fIanchor\fR is
-\f(CWcenter\fR then the widget is centered on the point; if \fIanchor\fR
-is \f(CWn\fR then the widget will be displayed such that the top center
-point of the rectangular region occupied by the widget will be at the
-positioning point.  This option defaults to \f(CWcenter\fR.
-.TP
-\fB\-height \fIpixels\fR
-Specifies the height to assign to the marker's window.  If this option
-isn't specified, or if it is specified as \f(CW""\fR, then the window is
-given whatever height the widget requests internally.
-.TP
-\fB\-width \fIpixels\fR
-Specifies the width to assign to the marker's window.  If this option
-isn't specified, or if it is specified as \f(CW""\fR, then the window is
-given whatever width the widget requests internally.
-.TP
-\fB\-window \fIpathName\fR
-Specifies the widget to be managed by the barchart.  \fIPathName\fR must
-be a child of the \fBbarchart\fR widget.
-.SH "GRAPH COMPONENT BINDINGS"
-Specific barchart components, such as elements, markers and legend
-entries, can have a command trigger when event occurs in them, much
-like canvas items in Tk's canvas widget.  Not all event sequences are
-valid.  The only binding events that may be specified are those
-related to the mouse and keyboard (such as \fBEnter\fR, \fBLeave\fR,
-\fBButtonPress\fR, \fBMotion\fR, and \fBKeyPress\fR).
-.PP
-Only one element or marker can be picked during an event.  This means,
-that if the mouse is directly over both an element and a marker, only
-the uppermost component is selected.  This isn't true for legend entries.  
-Both a legend entry and an element (or marker) binding commands 
-will be invoked if both items are picked.
-.PP
-It is possible for multiple bindings to match a particular event.
-This could occur, for example, if one binding is associated with the
-element name and another is associated with one of the element's tags
-(see the \fB\-bindtags\fR option).  When this occurs, all of the 
-matching bindings are invoked.  A binding associated with the element
-name is invoked first, followed by one binding for each of the element's 
-bindtags.  If there are multiple matching bindings for a single tag, 
-then only the most specific binding is invoked.  A continue command 
-in a binding script terminates that script, and a break command 
-terminates that script and skips any remaining scripts for the event, 
-just as for the bind command.
-.PP
-The \fB\-bindtags\fR option for these components controls addition
-tag names which can be matched.  Implicitly elements and markers
-always have tags matching their names.  Setting the value of
-the \fB\-bindtags\fR option doesn't change this.
-.SH "C LANGUAGE API"
-You can manipulate data elements from the C language.  There
-may be situations where it is too expensive to translate the data
-values from ASCII strings.  Or you might want to read data in a
-special file format.
-.PP
-Data can manipulated from the C language using BLT vectors.
-You specify the X-Y data coordinates of an element as vectors and
-manipulate the vector from C.  The barchart will be redrawn automatically
-after the vectors are updated.
-.PP
-From Tcl, create the vectors and configure the element to use them.
-.CS
-vector X Y
-\&.g element configure line1 -xdata X -ydata Y
-.CE
-To set data points from C, you pass the values as arrays of doubles
-using the \fBBlt_ResetVector\fR call.  The vector is reset with the
-new data and at the next idle point (when Tk re-enters its event
-loop), the graph will be redrawn automatically.

-.SH SPEED TIPS
-There may be cases where the bar chart needs to be drawn and updated as
-quickly as possible.  If drawing speed becomes a big
-problem, here are a few tips to speed up displays.
-.TP 2
-\(bu 
-Try to minimize the number of data points.  The more data points 
-looked at, the more work the bar chart must do.  
-.TP 2
-\(bu 
-If your data is generated as floating point values, the time required
-to convert the data values to and from ASCII strings can be
-significant, especially when there any many data points.  You can
-avoid the redundant string-to-decimal conversions using the C API to
-BLT vectors.
-.TP 2
-\(bu
-Don't stipple or dash the element.  Solid bars are much faster.
-.TP 2
-\(bu 
-If you update data elements frequently, try turning off the
-widget's \fB\-bufferelements\fR option.  When the bar chart is first
-displayed, it draws data elements into an internal pixmap.  The pixmap
-acts as a cache, so that when the bar chart needs to be redrawn again, and
-the data elements or coordinate axes haven't changed, the pixmap is
-simply copied to the screen.  This is especially useful when you are
-using markers to highlight points and regions on the bar chart.  But if
-the bar chart is updated frequently, changing either the element data or
-coordinate axes, the buffering becomes redundant.
-.SH LIMITATIONS
-Auto-scale routines do not use requested min/max limits
-as boundaries when the axis is logarithmically scaled.  
-.PP
-The PostScript output generated for polygons with more than 1500
-points may exceed the limits of some printers (See PostScript Language
-Reference Manual, page 568).  The work-around is to break the polygon
-into separate pieces.

-<H2>DESCRIPTION</H2><PRE>
-       The  <B>graph</B>  command  creates  a graph for plotting two-dimensional data
-       (X-Y coordinates). It  has  many  configurable  components:  coordinate
-       axes,  elements,  legend, grid lines, cross hairs, etc.  They allow you
-       to customize the look and feel of the graph.
-
-
-</PRE>
-<H2>INTRODUCTION</H2><PRE>
-       The <B>graph</B> command creates a new  window  for  plotting  two-dimensional
-       data  (X-Y coordinates).  Data points are plotted in a rectangular area
-       displayed in the center of the new window.  This is the <I>plotting</I>  <I>area</I>.
-       The  coordinate axes are drawn in the margins around the plotting area.
-       By default, the legend is displayed in the right margin.  The title  is
-       displayed in top margin.
-
-       The  <B>graph</B>  widget  is composed of several components: coordinate axes,
-       data elements, legend, grid, cross hairs, pens, postscript, and annota-
-       tion markers.
-
-       axis      The  graph has four standard axes (x, x2, y, and y2), but you
-                 can create and display any number of axes.  Axes control what
-                 region  of data is displayed and how the data is scaled. Each
-                 axis consists of the axis line, title, major and minor ticks,
-                 and tick labels.  Tick labels display the value at each major
-                 tick.
-
-       crosshairs
-                 Cross hairs are used to position the mouse  pointer  relative
-                 to  the  X  and  Y  coordinate axes. Two perpendicular lines,
-                 intersecting at the current location  of  the  mouse,  extend
-                 across the plotting area to the coordinate axes.
-
-       element   An  element  represents a set of data points. Elements can be
-                 plotted with a symbol at each data point and lines connecting
-                 the  points.  The appearance of the element, such as its sym-
-                 bol, line width, and color is configurable.
-
-       grid      Extends the major and minor ticks of the X-axis and/or Y-axis
-                 across the plotting area.
-
-       legend    The legend displays the name and symbol of each data element.
-                 The legend can be drawn in any  margin  or  in  the  plotting
-                 area.
-
-       marker    Markers  are  used  annotate or highlight areas of the graph.
-                 For example, you could use a polygon marker to fill  an  area
-                 under  a  curve,  or a text marker to label a particular data
-                 point. Markers come in various forms: text strings,  bitmaps,
-                 connected  line  segments, images, polygons, or embedded wid-
-                 gets.
-
-       <B>graph</B>  <I>pathName</I> ?<I>option</I> <I>value</I>?...  The <B>graph</B> command creates a new win-
-       dow <I>pathName</I> and makes it into a <B>graph</B> widget.  At the time  this  com-
-       mand  is  invoked,  there  must  not exist a window named <I>pathName</I>, but
-       <I>pathName</I>'s parent must exist.  Additional options may be  specified  on
-       the  command line or in the option database to configure aspects of the
-       graph such as its colors and font.  See the <B>configure</B>  operation  below
-       for the exact details about what <I>option</I> and <I>value</I> pairs are valid.
-
-       If successful, <B>graph</B> returns the path name of the widget.  It also cre-
-       ates a new Tcl command by the same name.  You can use this  command  to
-       invoke  various operations that query or modify the graph.  The general
-       form is: <I>pathName</I> <I>operation</I> ?<I>arg</I>?...  Both <I>operation</I> and its  arguments
-       determine  the exact behavior of the command.  The operations available
-       for the graph are described in the <B>GRAPH</B> <B>OPERATIONS</B> section.
-
-       The command can also be used to access components of the graph.   <I>path-</I>
-       <I>Name</I> <I>component</I> <I>operation</I> ?<I>arg</I>?...  The operation, now located after the
-       name of the component, is the function to be performed on  that  compo-
-       nent. Each component has its own set of operations that manipulate that
-       component.  They will be described below in their own sections.
-
-
-</PRE>
-<H2>EXAMPLE</H2><PRE>
-       The <B>graph</B> command creates a new graph.  # Create a new graph.  Plotting
-       area  is black.  graph .g -plotbackground black A new Tcl command .g is
-       also created.  This command can be used to query and modify the  graph.
-       For example, to change the title of the graph to "My Plot", you use the
-       new command and the graph's <B>configure</B> operation.  # Change  the  title.
-       .g configure -title "My Plot" A graph has several components. To access
-       a particular component you use the component's name.  For  example,  to
-       add  data  elements, you use the new command and the <B>element</B> component.
-       # Create a  new  element  named  "line1"  .g  element  create  line1  \
-            -xdata { 0.2 0.4 0.6 0.8 1.0 1.2 1.4 1.6 1.8 2.0 } \      -ydata {
-       26.18 50.46 72.85 93.31 111.86 128.47  143.14            155.85  166.60
-       175.38  }  The  element's  X-Y coordinates are specified using lists of
-       numbers.  Alternately, BLT vectors could be used to hold the X-Y  coor-
-       dinates.   # Create two vectors and add them to the graph.  vector xVec
-       yVec xVec set { 0.2 0.4 0.6 0.8 1.0 1.2 1.4 1.6 1.8 2.0 }  yVec  set  {
-       26.18  50.46 72.85 93.31 111.86 128.47 143.14 155.85      166.60 175.38
-       } .g element create line1 -xdata xVec  -ydata  yVec  The  advantage  of
-       using  vectors  is that when you modify one, the graph is automatically
-       redrawn to reflect the new values.  # Change the y  coordinate  of  the
-       first  point.   set <B>yVector(0)</B> 25.18 An element named e1 is now created
-       in .b.  It is automatically added to the display list of elements.  You
-       can  use this list to control in what order elements are displayed.  To
-       query or reset the element display list, you  use  the  element's  <B>show</B>
-       operation.   #  Get  the  current display list set elemList [.b element
-       show] # Remove the first element so it won't be displayed.  .b  element
-       show  [lrange $elemList 0 end] The element will be displayed by as many
-       bars as there are data points (in this case there are ten).   The  bars
-       will  be drawn centered at the x-coordinate of the data point.  All the
-       bars will have the same attributes (colors, stipple, etc).   The  width
-       of each bar is by default one unit.  You can change this with using the
-       example, you change the scale of the Y-axis from linear  to  log  using
-       the  <B>axis</B>  component.   #  Y-axis  is  log  scale.  .g axis configure y
-       -logscale yes One important way axes are used is to zoom in on  a  par-
-       ticular  data  region.   Zooming  is done by simply specifying new axis
-       limits using the <B>-min</B> and <B>-max</B> configuration options.  .g axis  config-
-       ure  x  -min  1.0  -max 1.5 .g axis configure y -min 12.0 -max 55.15 To
-       zoom interactively, you link the <B>axis</B> <B>configure</B>  operations  with  some
-       user  interaction  (such  as pressing the mouse button), using the <B>bind</B>
-       command.  To convert between screen  and  graph  coordinates,  use  the
-       <B>invtransform</B>  operation.   # Click the button to set a new minimum bind
-       .g &lt;ButtonPress-1&gt; {
-           %W axis configure x -min [%W axis invtransform x %x]
-           %W axis configure x -min [%W axis invtransform x %y] } By  default,
-       the  limits of the axis are determined from data values.  To reset back
-       to the default limits, set the <B>-min</B>  and  <B>-max</B>  options  to  the  empty
-       value.   # Reset the axes to autoscale again.  .g axis configure x -min
-       {} -max {} .g axis configure y -min {} -max {} By default,  the  legend
-       is  drawn  in the right margin.  You can change this or any legend con-
-       figuration options using the <B>legend</B> component.  # Configure the  legend
-       font,  color,  and  relief  .g  legend configure -position left -relief
-       raised \      -font fixed -fg blue To prevent  the  legend  from  being
-       displayed,  turn  on the <B>-hide</B> option.  # Don't display the legend.  .g
-       legend configure -hide yes The <B>graph</B> widget has simple  drawing  proce-
-       dures  called  markers.  They can be used to highlight or annotate data
-       in the graph. The types of markers available are bitmaps, images, poly-
-       gons,  lines, or windows.  Markers can be used, for example, to mark or
-       brush points.  In this example, is a text marker that labels  the  data
-       first point.  Markers are created using the <B>marker</B> component.  # Create
-       a label for the first data point of "line1".   .g  marker  create  text
-       -name  first_marker  -coords { 0.2 26.18 } \      -text "start" -anchor
-       se  -xoffset  -10  -yoffset  -10  This  creates  a  text  marker  named
-       first_marker.  It will display the text "start" near the coordinates of
-       the first data point.  The <B>-anchor</B>, <B>-xoffset</B>, and <B>-yoffset</B> options  are
-       used  to display the marker above and to the left of the data point, so
-       that the data point isn't covered by the marker.  By  default,  markers
-       are  drawn  last,  on top of data.  You can change this with the <B>-under</B>
-       option.  # Draw the label before elements are drawn.  .g marker config-
-       ure first_marker -under yes You can add cross hairs or grid lines using
-       the <B>crosshairs</B> and <B>grid</B> components.  # Display  both  cross  hairs  and
-       grid  lines.   .g crosshairs configure -hide no -color red .g grid con-
-       figure -hide no -dashes { 2 2 } # Set up a binding  to  reposition  the
-       crosshairs.  bind .g &lt;Motion&gt; {
-           .g crosshairs configure -position @%x,%y } The crosshairs are repo-
-       sitioned as the mouse pointer is moved in the graph.  The  pointer  X-Y
-       coordinates define the center of the crosshairs.
-
-       Finally, to get hardcopy of the graph, use the <B>postscript</B> component.  #
-       Print the graph into file "file.ps" .g postscript output file.ps  -max-
-       pect  yes  -decorations no This generates a file file.ps containing the
-       encapsulated PostScript of the graph.   The  option  <B>-maxpect</B>  says  to
-       scale  the  plot to the size of the page.  Turning off the <B>-decorations</B>
-       option denotes that no borders or color  backgrounds  should  be  drawn
-              <I>option</I>.   <I>Option</I>  may be any option described below for the <B>con-</B>
-              <B>figure</B> operation.
-
-       <I>pathName</I> <B>configure</B> ?<I>option</I> <I>value</I>?...
-              Queries or modifies the configuration options of the graph.   If
-              <I>option</I>  isn't  specified,  a list describing the current options
-              for <I>pathName</I> is returned.   If  <I>option</I>  is  specified,  but  not
-              <I>value</I>,  then  a  list  describing <I>option</I> is returned.  If one or
-              more <I>option</I> and <I>value</I> pairs are specified, then for  each  pair,
-              the  option  <I>option</I>  is set to <I>value</I>.  The following options are
-              valid.
-
-              <B>-aspect</B> <I>width/height</I>
-                     Force a fixed aspect ratio of  <I>width/height</I>,  a  floating
-                     point number.
-
-              <B>-background</B> <I>color</I>
-                     Sets  the background color. This includes the margins and
-                     legend, but not the plotting area.
-
-              <B>-borderwidth</B> <I>pixels</I>
-                     Sets the width of the 3-D border around the outside  edge
-                     of the widget.  The <B>-relief</B> option determines if the bor-
-                     der is to be drawn.  The default is 2.
-
-              <B>-bottommargin</B> <I>pixels</I>
-                     If non-zero, overrides the computed size  of  the  margin
-                     extending  below  the X-coordinate axis.  If <I>pixels</I> is 0,
-                     the automatically computed size is used.  The default  is
-                     0.
-
-              <B>-bufferelements</B> <I>boolean</I>
-                     Indicates  whether  an internal pixmap to buffer the dis-
-                     play of data elements should  be  used.   If  <I>boolean</I>  is
-                     true,  data  elements  are  drawn  to an internal pixmap.
-                     This option  is  especially  useful  when  the  graph  is
-                     redrawn  frequently while the remains data unchanged (for
-                     example, moving a marker across the plot).  See the <B>SPEED</B>
-                     <B>TIPS</B> section.  The default is 1.
-
-              <B>-cursor</B> <I>cursor</I>
-                     Specifies  the  widget's  cursor.   The default cursor is
-                     crosshair.
-
-              <B>-font</B> <I>fontName</I>
-                     Specifies the font of the graph  title.  The  default  is
-                     *-Helvetica-Bold-R-Normal-*-18-180-*.
-
-              <B>-halo</B> <I>pixels</I>
-                     Specifies  a  maximum distance to consider when searching
-                     for the closest data point  (see  the  element's  <B>closest</B>
-                     operation  below).   Data points further than <I>pixels</I> away
-                     text.  <I>Justify</I>  must  be  left,  right,  or  center.  The
-                     default is center.
-
-              <B>-leftmargin</B> <I>pixels</I>
-                     If non-zero, overrides the computed size  of  the  margin
-                     extending from the left edge of the window to the Y-coor-
-                     dinate axis.  If <I>pixels</I> is 0, the automatically  computed
-                     size is used.  The default is 0.
-
-              <B>-plotbackground</B> <I>color</I>
-                     Specifies the background color of the plotting area.  The
-                     default is white.
-
-              <B>-plotborderwidth</B> <I>pixels</I>
-                     Sets the width of the  3-D  border  around  the  plotting
-                     area.   The  <B>-plotrelief</B> option determines if a border is
-                     drawn.  The default is 2.
-
-              <B>-plotpadx</B> <I>pad</I>
-                     Sets the amount of padding to be added to  the  left  and
-                     right  sides  of the plotting area.  <I>Pad</I> can be a list of
-                     one or two screen distances.  If <I>pad</I>  has  two  elements,
-                     the left side of the plotting area entry is padded by the
-                     first distance and the right side by the second.  If  <I>pad</I>
-                     is  just  one distance, both the left and right sides are
-                     padded evenly.  The default is 8.
-
-              <B>-plotpady</B> <I>pad</I>
-                     Sets the amount of padding to be added  to  the  top  and
-                     bottom of the plotting area.  <I>Pad</I> can be a list of one or
-                     two screen distances.  If <I>pad</I> has two elements,  the  top
-                     of  the plotting area is padded by the first distance and
-                     the bottom by the second.  If <I>pad</I> is just  one  distance,
-                     both  the  top and bottom are padded evenly.  The default
-                     is 8.
-
-              <B>-plotrelief</B> <I>relief</I>
-                     Specifies the 3-D effect for the plotting  area.   <I>Relief</I>
-                     specifies  how  the  interior of the plotting area should
-                     appear relative to rest of the graph; for example, raised
-                     means  the plot should appear to protrude from the graph,
-                     relative to the surface of the  graph.   The  default  is
-                     sunken.
-
-              <B>-relief</B> <I>relief</I>
-                     Specifies  the  3-D  effect for the graph widget.  <I>Relief</I>
-                     specifies how the graph should appear relative to  widget
-                     it  is  packed  into; for example, raised means the graph
-                     should appear to protrude.  The default is flat.
-
-              <B>-rightmargin</B> <I>pixels</I>
-                     If non-zero, overrides the computed size  of  the  margin
-
-              <B>-tile</B> <I>image</I>
-                     Specifies  a  tiled  background for the widget.  If <I>image</I>
-                     isn't "", the background is tiled  using  <I>image</I>.   Other-
-                     wise,  the  normal  background  color  is  drawn (see the
-                     <B>-background</B> option).  <I>Image</I>  must  be  an  image  created
-                     using the Tk <B>image</B> command.  The default is "".

-
-              <B>-topmargin</B> <I>pixels</I>
-                     If non-zero, overrides the computed size  of  the  margin
-                     above  the  x2  axis.   If <I>pixels</I> is 0, the automatically
-                     computed size is used.  The default is 0.
-
-              <B>-width</B> <I>pixels</I>
-                     Specifies the requested width of the widget.  The default

-<H2>GRAPH COMPONENTS</H2><PRE>
-       A graph is composed of several components: coordinate axes,  data  ele-
-       ments,  legend,  grid, cross hairs, postscript, and annotation markers.
-       Instead of one big set of configuration  options  and  operations,  the
-       graph  is  partitioned,  where each component has its own configuration
-       options and operations that specifically control that aspect or part of
-       the graph.
-
-   <B>AXIS</B> <B>COMPONENTS</B>
-       Four  coordinate  axes are automatically created: two X-coordinate axes
-       You can have several axes. To create an axis, invoke the axis component
-       and  its  create  operation.   # Create a new axis called "tempAxis" .g
-       axis create tempAxis You map data elements to an axis  using  the  ele-
-       ment's  -mapy and -mapx configuration options. They specify the coordi-
-       nate axes an element is mapped onto.  # Now map the  tempAxis  data  to
-       this  axis.   .g element create "e1" -xdata $x -ydata $y -mapy tempAxis
-       Any number of axes can be displayed simultaneously. They are  drawn  in
-       the  margins  surrounding  the plotting area.  The default axes x and y
-       are drawn in the bottom and left margins. The axes x2 and y2 are  drawn
-       in  top  and  right  margins.  By default, only x and y are shown. Note
-       that the axes can have different scales.
-
-       To display a different axis or more than one axis, you  invoke  one  of
-       the  following components: <B>xaxis</B>, <B>yaxis</B>, <B>x2axis</B>, and <B>y2axis</B>.  Each com-
-       ponent has a <B>use</B> operation that designates the axis  (or  axes)  to  be
-       drawn  in  that corresponding margin: <B>xaxis</B> in the bottom, <B>yaxis</B> in the
-       left, <B>x2axis</B> in the top, and <B>y2axis</B> in the right.  # Display  the  axis
-       tempAxis  in  the left margin.  .g yaxis use tempAxis The <B>use</B> operation
-       takes a list of axis names as its last argument.  This is the  list  of
-       axes to be drawn in this margin.
-
-       You  can  configure  axes in many ways. The axis scale can be linear or
-       logarithmic.  The  values  along  the  axis  can  either  monotonically
-       increase  or decrease.  If you need custom tick labels, you can specify
-       a Tcl procedure to format the label any way you wish.  You can  control
-       how  ticks are drawn, by changing the major tick interval or the number
-       of minor ticks.  You can define non-uniform tick intervals, such as for
-       time-series plots.
-
-
-       <I>pathName</I> <B>axis</B> <B>bind</B> <I>tagName</I> ?<I>sequence</I>?  ?<I>command</I>?
-              Associates  <I>command</I>  with  <I>tagName</I>  such that whenever the event
-              sequence given by <I>sequence</I> occurs for an  axis  with  this  tag,
-              <I>command</I> will be invoked.  The syntax is similar to the <B>bind</B> com-
-              mand except that it operates on graph axes, rather than widgets.
-              See  the  <B>bind</B> manual entry for complete details on <I>sequence</I> and
-              the substitutions performed on <I>command</I> before invoking it.
-
-              If all arguments are specified then a new  binding  is  created,
-              replacing  any  existing  binding for the same <I>sequence</I> and <I>tag-</I>
-              <I>Name</I>.  If the first character of <I>command</I> is + then <I>command</I>  aug-
-              ments  an existing binding rather than replacing it.  If no <I>com-</I>
-              <I>mand</I> argument is provided then the command currently  associated
-              with  <I>tagName</I>  and  <I>sequence</I> (it's an error occurs if there's no
-              such binding) is returned.  If both  <I>command</I>  and  <I>sequence</I>  are
-              missing  then  a list of all the event sequences for which bind-
-              ings have been defined for <I>tagName</I>.
-
-       <I>pathName</I> <B>axis</B> <B>cget</B> <I>axisName</I> <I>option</I>
-              Returns the current value of the  option  given  by  <I>option</I>  for
-              <I>axisName</I>.  <I>Option</I> may be any option described below for the axis
-              <B>configure</B> operation.
-                     the  list  matching  the current event sequence will have
-                     its Tcl command executed.  Implicitly  the  name  of  the
-                     element is always the first tag in the list.  The default
-                     value is all.
-
-              <B>-color</B> <I>color</I>
-                     Sets the color of the axis and tick labels.  The  default
-                     is black.
-
-              <B>-descending</B> <I>boolean</I>
-                     Indicates whether the values along the axis are monotoni-
-                     cally increasing or decreasing.  If <I>boolean</I> is true,  the
-                     axis values will be decreasing.  The default is 0.
-
-              <B>-hide</B> <I>boolean</I>
-                     Indicates  if  the axis is displayed. If <I>boolean</I> is false
-                     the axis will be displayed. Any  element  mapped  to  the
-                     axis is displayed regardless.  The default value is 0.
-
-              <B>-justify</B> <I>justify</I>
-                     Specifies  how  the axis title should be justified.  This
-                     matters only when the axis title contains more  than  one
-                     line  of  text.  <I>Justify</I>  must be left, right, or center.
-                     The default is center.
-
-              <B>-limits</B> <I>formatStr</I>
-                     Specifies a printf-like description to format the minimum
-                     and maximum limits of the axis.  The limits are displayed
-                     at the top/bottom or left/right  sides  of  the  plotting
-                     area.   <I>FormatStr</I> is a list of one or two format descrip-
-                     tions.  If one description is supplied, both the  minimum
-                     and  maximum  limits  are  formatted in the same way.  If
-                     two, the first designates  the  format  for  the  minimum
-                     limit,  the  second  for  the maximum.  If "" is given as
-                     either description, then the that limit will not be  dis-
-                     loosely, at the outer tick intervals.  If the axis  limit
-                     is  set  with  the -min or -max option, the axes are dis-
-                     played tightly.  If <I>boolean</I> is true, the  axis  range  is
-                     "loose".  The default is 0.
-
-              <B>-majorticks</B> <I>majorList</I>
-                     Specifies where to display major axis ticks.  You can use
-                     this option to display ticks  at  non-uniform  intervals.
-                     <I>MajorList</I>  is  a list of axis coordinates designating the
-                     location of major ticks.  No minor ticks are  drawn.   If
-                     <I>majorList</I>  is  "", major ticks will be automatically com-
-                     puted. The default is "".
-
-              <B>-max</B> <I>value</I>
-                     Sets the maximum  limit  of  <I>axisName</I>.   Any  data  point
-                     greater than <I>value</I> is not displayed.  If <I>value</I> is "", the
-                     maximum limit is calculated using the largest data value.
-                     The default is "".
-
-              <B>-min</B> <I>value</I>
-                     Sets  the  minimum limit of <I>axisName</I>. Any data point less
-                     than <I>value</I> is not displayed.  If <I>value</I> is "", the minimum
-                     limit  is  calculated using the smallest data value.  The
-                     default is "".
-
-              <B>-minorticks</B> <I>minorList</I>
-                     Specifies where to display minor axis ticks.  You can use
-                     this  option to display minor ticks at non-uniform inter-
-                     vals. <I>MinorList</I> is a list of real  values,  ranging  from
-                     0.0  to  1.0,  designating the placement of a minor tick.
-                     No minor ticks are drawn if the <B>-majortick</B> option is also
-                     set.   If  <I>minorList</I> is "", minor ticks will be automati-
-                     cally computed. The default is "".
-
-              <B>-rotate</B> <I>theta</I>
-                     Specifies the how many degrees to rotate  the  axis  tick
-                     labels.  <I>Theta</I> is a real value representing the number of
-                     degrees to rotate the tick labels.  The  default  is  0.0
-                     degrees.
-
-              <B>-scrollcommand</B> <I>command</I>
-                     Specify the prefix for a command used to communicate with
-                     scrollbars for this axis, such as <I>.sbar</I> <I>set</I>.
-
-              <B>-scrollmax</B> <I>value</I>
-                     Sets the maximum limit of the  axis  scroll  region.   If
-                     <I>value</I>  is  "",  the maximum limit is calculated using the
-                     largest data value.  The default is "".
-
-              <B>-scrollmin</B> <I>value</I>
-                     Sets the minimum limit of axis scroll region.   If  <I>value</I>
-                     is "", the minimum limit is calculated using the smallest
-                     Indicates how many minor axis ticks are to be drawn.  For
-                     example, if <I>number</I> is two, only one minor tick is  drawn.
-                     If  <I>number</I>  is  one,  no  minor ticks are displayed.  The
-                     default is 2.
-
-              <B>-tickfont</B> <I>fontName</I>
-                     Specifies the font for axis tick labels. The  default  is
-                     *-Courier-Bold-R-Normal-*-100-*.
-
-              <B>-tickformat</B> <I>formatStr</I>
-                     Specifies a printf-like description to format teh axis
-                     tick labels.  You can get the standard tick labels again by
-                     setting <I>formatStr</I> to "".  The default is "".
-
-              <B>-tickformatcommand</B>, <B>-command</B> <I>prefix</I>
-                     Specifies a Tcl command to be invoked when formatting the
-                     axis tick labels. <I>Prefix</I> is a string containing the  name
-                     of  a Tcl proc and any extra arguments for the procedure.
-                     This command is invoked for each major tick on the  axis.
-                     Two additional arguments are passed to the procedure: the
-                     pathname of the widget and the current the numeric  value
-                     of  the  tick.   The procedure returns the formatted tick
-                     label.  If "" is returned, no label will appear  next  to
-                     the  tick.  You can get the standard tick labels again by
-                     setting <I>prefix</I> to "".  The default is "".
-
-                     The numeric value for the tick might change when using the
-                     <B>-logscale</B> and <B>-tickformat</B> options.
-
-                     Please note that this  procedure  is  invoked  while  the
-                     graph  is  redrawn.  You may query configuration options.
-                     But  do  not  them,  because  this  can  have  unexpected
-                     results.
-
-              <B>-ticklength</B> <I>pixels</I>
-                     Sets the length of major and minor ticks (minor ticks are
-                     half the length of major ticks). If <I>pixels</I> is  less  than
-                     zero, the axis will be inverted with ticks drawn pointing
-                     towards the plot.  The default is 0.1i.
-
-              <B>-title</B> <I>text</I>
-                     Sets the title of the axis. If <I>text</I> is "", no axis  title
-                     will be displayed.
-
-              <B>-titlealternate</B> <I>boolean</I>
-                     Indicates  to  display  the  axis  title in its alternate
-                     location.  Normally the axis title is centered along  the
-                     axis.   This  option  places the axis either to the right
-                     (horizontal axes) or above (vertical axes) the axis.  The
-                     default is 0.
-
-              <B>-titlecolor</B> <I>color</I>
-                     Sets the color of the axis title. The default is black.
-
-              <B>-titlefont</B> <I>fontName</I>
-                     Specifies  the font for axis title. The default is *-Hel-
-                     vetica-Bold-R-Normal-*-14-140-*.
-
-              Axis configuration options may be also be set by the <B>option</B> com-
-              mand.   The  resource class is Axis.  The resource names are the
-              names  of  the  axes  (such   as   x   or   x2).    option   add
-              *Graph.Axis.Color    blue  option  add  *Graph.x.LogScale   true
-              option add *Graph.x2.LogScale false
-
-       <I>pathName</I> <B>axis</B> <B>create</B> <I>axisName</I> ?<I>option</I> <I>value</I>?...
-              Creates a new axis by the name <I>axisName</I>.  No axis  by  the  same
-              name  can already exist. <I>Option</I> and <I>value</I> are described in above
-              in the axis <B>configure</B> operation.
-
-       <I>pathName</I> <B>axis</B> <B>delete</B> ?<I>axisName</I>?...
-              Deletes the named axes. An axis is not really deleted  until  it
-              is not longer in use, so it's safe to delete axes mapped to ele-
-              ments.
-
-       <I>pathName</I> <B>axis</B> <B>invtransform</B> <I>axisName</I> <I>value</I>
-              Performs the inverse transformation, changing the screen coordi-
-              nate  <I>value</I>  to  a graph coordinate, mapping the value mapped to
-
-       <I>pathName</I> <B>axis</B> <B>view</B> <I>axisName</I>
-              Change the viewable area of this axis. Use as an argument  to  a
-              scrollbar's "<I>-command</I>".
-
-       The  default  axes are x, y, x2, and y2.  But you can display more than
-       four axes simultaneously.  You can also swap in a different  axis  with
-       <B>use</B> operation of the special axis components: <B>xaxis</B>, <B>x2axis</B>, <B>yaxis</B>, and
-       <B>y2axis</B>.  .g create axis temp .g create axis time ...  .g xaxis use temp
-       .g  yaxis use time Only the axes specified for use are displayed on the
-       screen.
-
-       The <B>xaxis</B>, <B>x2axis</B>, <B>yaxis</B>, and <B>y2axis</B>  components  operate  on  an  axis
-       location  rather than a specific axis like the more general <B>axis</B> compo-
-       nent does.  They implicitly control the axis that is currently using to
-       that location.  By default, <B>xaxis</B> uses the x axis, <B>yaxis</B> uses y, <B>x2axis</B>
-       uses x2, and <B>y2axis</B> uses y2.  When more than one axis is displayed in a
-       margin, it represents the first axis displayed.
-
-       The  following  operations  are available for axes. They mirror exactly
-       the operations of the <B>axis</B> component.  The <I>axis</I> argument must be <B>xaxis</B>,
-       <B>x2axis</B>,  <B>yaxis</B>,  or <B>y2axis</B>.  This feature is deprecated since more than
-       one axis can now be used a margin.  You  should  only  use  the  <B>xaxis</B>,
-       <B>x2axis</B>,  <B>yaxis</B>,  and <B>y2axis</B> components with the <B>use</B> operation.  For all
-       other operations, use the general <B>axis</B> component instead.
-
-       <I>pathName</I> <I>axis</I> <B>cget</B> <I>option</I>
-
-       <I>pathName</I> <I>axis</I> <B>configure</B> ?<I>option</I> <I>value</I>?...
-
-       <I>pathName</I> <I>axis</I> <B>invtransform</B> <I>value</I>
-
-       <I>pathName</I> <I>axis</I> <B>limits</B>
-
-       <I>pathName</I> <I>axis</I> <B>transform</B> <I>value</I>
-
-       <I>pathName</I> <I>axis</I> <B>use</B> ?<I>axisName</I>?
-              Designates the axis <I>axisName</I> is to be displayed  at  this  loca-
-              tion.   <I>AxisName</I>  can not be already in use at another location.
-              This command returns the name of the axis currently  using  this
-              location.
-
-   <B>CROSSHAIRS</B> <B>COMPONENT</B>
-       Cross  hairs  consist  of  two intersecting lines (one vertical and one
-       horizontal) drawn completely across the plotting area.  They  are  used
-       to  position the mouse in relation to the coordinate axes.  Cross hairs
-       differ from line markers in that they are implemented using XOR drawing
-       primitives.  This means that they can be quickly drawn and erased with-
-       out redrawing the entire graph.
-
-       The following operations are available for cross hairs:
-
-              <B>-color</B> <I>color</I>
-                     Sets the color of the cross hairs.  The default is black.
-
-              <B>-dashes</B> <I>dashList</I>
-                     Sets  the  dash  style  of the cross hairs. <I>DashList</I> is a
-                     list of up to 11 numbers that alternately  represent  the
-                     lengths  of  the dashes and gaps on the cross hair lines.
-                     Each number must be between 1 and 255.   If  <I>dashList</I>  is
-                     "", the cross hairs will be solid lines.
-
-              <B>-hide</B> <I>boolean</I>
-                     Indicates  whether  cross  hairs are drawn. If <I>boolean</I> is
-                     true, cross hairs are not drawn.  The default is yes.
-
-              <B>-linewidth</B> <I>pixels</I>
-                     Set the width of the cross hair lines.  The default is 1.
-
-              <B>-position</B> <I>pos</I>
-                     Specifies  the  screen  position  where  the  cross hairs
-                     intersect.  <I>Pos</I> must be in the form "<I>@x,y</I>", where <I>x</I> and <I>y</I>
-                     are the window coordinates of the intersection.
-
-              Cross  hairs  configuration  options  may  be also be set by the
-              <B>option</B> command.  The resource name and class are crosshairs  and
-              Crosshairs respectively.  option add *Graph.Crosshairs.LineWidth
-              2 option add *Graph.Crosshairs.Color     red
-
-       <I>pathName</I> <B>crosshairs</B> <B>off</B>
-              Turns off the cross hairs.
-
-       <I>pathName</I> <B>crosshairs</B> <B>on</B>
-              Turns on the display of the cross hairs.
-
-       <I>pathName</I> <B>crosshairs</B> <B>toggle</B>
-              Toggles the current state of the cross hairs,  alternately  map-
-              ping and unmapping the cross hairs.
-
-   <B>ELEMENT</B> <B>COMPONENTS</B>
-       A  data  element represents a set of data.  It contains x and y vectors
-       containing the coordinates of the data points.  Elements  can  be  dis-
-       played  with  a  symbol  at  each  data  point and lines connecting the
-       points.  Elements also control the appearance of the data, such as  the
-       symbol type, line width, color etc.
-
-       When  new  data elements are created, they are automatically added to a
-       list of displayed elements.   The display list controls  what  elements
-       are drawn and in what order.
-
-       The following operations are available for elements.
-
-       <I>pathName</I> <B>element</B> <B>activate</B> <I>elemName</I> ?<I>index</I>?...

-              replacing  any  existing  binding for the same <I>sequence</I> and <I>tag-</I>
-              <I>Name</I>.  If the first character of <I>command</I> is + then <I>command</I>  aug-
-              ments  an existing binding rather than replacing it.  If no <I>com-</I>
-              <I>mand</I> argument is provided then the command currently  associated
-              with  <I>tagName</I>  and  <I>sequence</I> (it's an error occurs if there's no
-              such binding) is returned.  If both  <I>command</I>  and  <I>sequence</I>  are
-              missing  then  a list of all the event sequences for which bind-
-              ings have been defined for <I>tagName</I>.

-              and  <I>y</I>.  By default, all elements are searched.  Hidden elements
-              (see the <B>-hide</B> option is false) are ignored.  You can limit  the
-              search  by  specifying  only the elements you want to be consid-
-              ered.  <I>ElemName</I> must be the name of an element that can  not  be
-              hidden.   It returns a key-value list containing the name of the
-              closest element, the index of the closest data  point,  and  the
-              graph-coordinates  of  the  point.  Returns "", if no data point
-              within the  threshold  distance  can  be  found.  The  following

-                     list of binding tag names.  The tags and their order will
-                     determine how events are handled for elements.  Each  tag
-                     in the list matching the current event sequence will have
-                     its Tcl command executed.  Implicitly  the  name  of  the
-                     element is always the first tag in the list.  The default
-                     value is all.

-                     the <B>-dashes</B> option).  If <I>color</I> is "", then the "off" pix-
-                     els  will represent gaps instead of stripes.  If <I>color</I> is
-                     defcolor, then the color will be the same as  the  <B>-color</B>
-                     option.  The default is defcolor.

-              <B>-outline</B> <I>color</I>
-                     Sets  the  color  or  the outline around each symbol.  If
-                     <I>color</I> is "", then no outline is drawn. If <I>color</I>  is  def-
-                     color,  then  the  color  will  be the same as the <B>-color</B>
-                     option.  The default is defcolor.
-
-              <B>-pen</B> <I>penname</I>
-                     Set the pen to use for this element.

-
-              <B>-scalesymbols</B> <I>boolean</I>
-                     If  <I>boolean</I>  is  true,  the size of the symbols drawn for
-                     <I>elemName</I> will change with scale of the X-axis and Y-axis.
-                     At the time this option is set, the current ranges of the
-                     axes are saved as the normalized scales (i.e scale factor
-                     is  1.0)  and the element is drawn at its designated size
-                     (see the <B>-pixels</B> option).   As  the  scale  of  the  axes
-                     change,  the  symbol  will  be  scaled  according  to the
-                     smaller of the X-axis and Y-axis scales.  If  <I>boolean</I>  is
-                     dratic spline is used.  The default is <I>linear</I>.

-                     in  this  range, are drawn with this pen.  If no range is
-                     specified it defaults to the index  of  the  pen  in  the
-                     list.   Note  that  this  affects only symbol attributes.
-                     Line attributes, such as line  width,  dashes,  etc.  are

-                     decreasing) are drawn.   <I>Direction</I>  must  be  increasing,
-                     decreasing,  or  both.   For  example,  if  <I>direction</I>  is
-                     increasing, connecting lines will be drawn  only  between
-                     those data points where X-coordinate values are monotoni-
-                     cally increasing.  If <I>direction</I> is both, connecting lines
-                     will  be  draw  between  all data points.  The default is

-   <B>LEGEND</B> <B>COMPONENT</B>
-       The legend displays a list of the data elements.  Each  entry  consists
-       of the element's symbol and label.  The legend can appear in any margin
-       (the default location is in the right margin).  It can  also  be  posi-
-       tioned anywhere within the plotting area.
-
-       The following operations are valid for the legend.
-
-       <I>pathName</I> <B>legend</B> <B>activate</B> <I>pattern</I>...
-              Selects  legend entries to be drawn using the active legend col-
-              ors and relief.  All entries whose element names  match  <I>pattern</I>
-              are  selected.  To be selected, the element name must match only
-              one <I>pattern</I>.
-
-       <I>pathName</I> <B>legend</B> <B>bind</B> <I>tagName</I> ?<I>sequence</I>?  ?<I>command</I>?
-              Associates <I>command</I> with <I>tagName</I> such  that  whenever  the  event
-              sequence  given  by <I>sequence</I> occurs for a legend entry with this
-              tag, <I>command</I> will be invoked.  Implicitly the element  names  in
-              the  entry  are tags.  The syntax is similar to the <B>bind</B> command
-              except that it operates on legend entries, rather than  widgets.
-              See  the  <B>bind</B> manual entry for complete details on <I>sequence</I> and
-              the substitutions performed on <I>command</I> before invoking it.
-
-              If all arguments are specified then a new  binding  is  created,
-              replacing  any  existing  binding for the same <I>sequence</I> and <I>tag-</I>
-              <I>Name</I>.  If the first character of <I>command</I> is + then <I>command</I>  aug-
-              ments  an existing binding rather than replacing it.  If no <I>com-</I>
-              <I>mand</I> argument is provided then the command currently  associated
-              with  <I>tagName</I>  and  <I>sequence</I> (it's an error occurs if there's no
-              such binding) is returned.  If both  <I>command</I>  and  <I>sequence</I>  are
-              missing  then  a list of all the event sequences for which bind-
-              ings have been defined for <I>tagName</I>.
-
-              <B>-activebackground</B> <I>color</I>
-                     Sets the background color for active legend entries.  All
-                     legend  entries  marked  active  (see the legend <B>activate</B>
-                     operation) are drawn using this background color.
-
-              <B>-activeborderwidth</B> <I>pixels</I>
-                     Sets the width of the 3-D border around the outside  edge
-                     of the active legend entries.  The default is 2.
-
-              <B>-activeforeground</B> <I>color</I>
-                     Sets the foreground color for active legend entries.  All
-                     legend entries marked as active (see the legend  <B>activate</B>
-                     operation) are drawn using this foreground color.
-
-              <B>-activerelief</B> <I>relief</I>
-                     Specifies  the  3-D  effect  desired  for  active  legend
-                     entries.  <I>Relief</I> denotes how the interior  of  the  entry
-                     should appear relative to the legend; for example, raised
-                     means the entry should appear to protrude from  the  leg-
-                     end,  relative to the surface of the legend.  The default
-                     is flat.
-
-              <B>-anchor</B> <I>anchor</I>
-                     Tells how to position the legend relative  to  the  posi-
-                     tioning  point  for the legend.  This is dependent on the
-                     value of the <B>-position</B> option.  The default is center.
-
-                     left or right
-                                 The anchor describes how to position the leg-
-                                 end vertically.
-
-                     top or bottom
-                                 The anchor describes how to position the leg-
-                                 end horizontally.
-
-                     @x,y        The anchor specifies how to position the leg-
-                                 end  relative  to  the positioning point. For
-                                 example, if <I>anchor</I> is center then the  legend
-                                 is centered on the point; if <I>anchor</I> is n then
-                                 the legend will be drawn such  that  the  top
-                                 center  point of the rectangular region occu-
-                                 pied by the legend will be at the positioning
-                                 point.
-
-                     plotarea    The anchor specifies how to position the leg-
-                                 end relative to the plotting area. For  exam-
-                                 ple,  if  <I>anchor</I> is center then the legend is
-                                 centered in the plotting area; if  <I>anchor</I>  is
-                                 ne  then  the  legend will be drawn such that
-                                 occupies the upper right corner of the  plot-
-                                 ting area.
-
-                     Sets  the width of the 3-D border around the outside edge
-                     of the legend (if such border is being drawn; the  <B>relief</B>
-                     option determines this).  The default is 2 pixels.
-
-              <B>-font</B> <I>fontName</I>
-                     <I>FontName</I>  specifies a font to use when drawing the labels
-                     of each element into the legend.  The default  is  *-Hel-
-                     vetica-Bold-R-Normal-*-12-120-*.
-
-              <B>-foreground</B> <I>color</I>
-                     Sets  the foreground color of the text drawn for the ele-
-                     ment's label.  The default is black.
-
-              <B>-hide</B> <I>boolean</I>
-                     Indicates whether the  legend  should  be  displayed.  If
-                     <I>boolean</I>  is  true,  the  legend  will  not  be draw.  The
-                     default is no.
-
-              <B>-ipadx</B> <I>pad</I>
-                     Sets the amount of internal padding to be  added  to  the
-                     width  of each legend entry.  <I>Pad</I> can be a list of one or
-                     two screen distances.  If <I>pad</I> has two elements, the  left
-                     side  of the legend entry is padded by the first distance
-                     and the right side by the second.  If  <I>pad</I>  is  just  one
-                     distance,  both  the  left  and  right  sides  are padded
-                     evenly.  The default is 2.
-
-              <B>-ipady</B> <I>pad</I>
-                     Sets an amount of internal padding to  be  added  to  the
-                     height of each legend entry.  <I>Pad</I> can be a list of one or
-                     two screen distances.  If <I>pad</I> has two elements,  the  top
-                     of the entry is padded by the first distance and the bot-
-                     tom by the second.  If <I>pad</I> is just one distance, both the
-                     top  and  bottom  of  the  entry  are padded evenly.  The
-                     default is 2.
-
-              <B>-padx</B> <I>pad</I>
-                     Sets the padding to the left and right exteriors  of  the
-                     legend.   <I>Pad</I>  can  be  a  list of one or two screen dis-
-                     tances.  If <I>pad</I> has two elements, the left  side  of  the
-                     legend is padded by the first distance and the right side
-                     by the second.  If <I>pad</I> has just one  distance,  both  the
-                     left  and  right sides are padded evenly.  The default is
-                     4.
-
-              <B>-pady</B> <I>pad</I>
-                     Sets the padding above and below the legend.  <I>Pad</I> can  be
-                     a  list  of  one or two screen distances.  If <I>pad</I> has two
-                     elements, the area above the  legend  is  padded  by  the
-                     first  distance and the area below by the second.  If <I>pad</I>
-                     is just one distance, both the top and bottom  areas  are
-                     padded evenly.  The default is 0.
-                     plotting area.  If <I>boolean</I> is true, the  legend  will  be
-                     drawn  on  top  of  any elements that may overlap it. The
-                     default is no.
-
-              <B>-relief</B> <I>relief</I>
-                     Specifies the 3-D effect for the border around  the  leg-
-                     end.   <I>Relief</I>  specifies  how  the interior of the legend
-                     should appear relative to the graph; for example,  raised
-                     means  the  legend  should  appear  to  protrude from the

-              Selects legend entries to be drawn using the normal legend  col-
-              ors  and  relief.  All entries whose element names match <I>pattern</I>
-              are selected.  To be selected, the element name must match  only

-       <I>pathName</I> <B>legend</B> <B>get</B> <I>pos</I>
-              Returns  the  name  of  the element whose entry is at the screen
-              position <I>pos</I> in the legend.  <I>Pos</I> must be  in  the  form  "<I>@x,y</I>",
-              where  <I>x</I> and <I>y</I> are window coordinates.  If the given coordinates
-              do not lie over a legend entry, "" is returned.
-
-   <B>PEN</B> <B>COMPONENTS</B>
-       Pens define attributes (both symbol and line style) for elements.  Pens
-       mirror  the  configuration options of data elements that pertain to how
-       symbols and lines are drawn.  Data elements use pens to  determine  how
-       they  are drawn.  A data element may use several pens at once.  In this
-       case, the pen used for a particular data point is determined from  each
-       element's weight vector (see the element's <B>-weight</B> and <B>-style</B> options).
-
-       One pen, called activeLine, is automatically created.  It's used as the
-       default  active  pen  for  elements.  So  you  can  change  the  active
-       attributes for all elements by simply reconfiguring this pen.   .g  pen
-       configure  "activeLine"  -color  green  You  can create and use several
-       pens. To create a pen, invoke the pen component and its  create  opera-
-       tion.   .g pen create myPen You map pens to a data element using either
-       the element's <B>-pen</B> or <B>-activepen</B> options.  .g  element  create  "line1"
-       -xdata $x -ydata $tempData \
-           -pen myPen An element can use several pens at once. This is done by
-       specifying the name of the pen in the element's  style  list  (see  the
-       <B>-styles</B>  option).  .g element configure "line1" -styles { myPen 2.0 3.0
-       } This says that any data point with a weight between 2.0 and 3.0 is to
-       be drawn using the pen myPen.  All other points are drawn with the ele-
-       ment's default attributes.
-
-              specified,  then  for each pair, the pen option <I>option</I> is set to
-              <I>value</I>.  The following options are valid for pens.
-
-              <B>-color</B> <I>color</I>
-                     Sets the color of the traces connecting the data  points.
-
-              <B>-dashes</B> <I>dashList</I>
-                     Sets  the  dash style of element line. <I>DashList</I> is a list
-                     of up  to  11  numbers  that  alternately  represent  the
-                     lengths of the dashes and gaps on the element line.  Each
-                     number must be between 1 and 255.  If <I>dashList</I> is "", the
-                     lines will be solid.
-
-              <B>-fill</B> <I>color</I>
-                     Sets the interior color of symbols.  If <I>color</I> is "", then
-                     the interior of the symbol is transparent.  If  <I>color</I>  is
-                     defcolor,  then  the color will be the same as the <B>-color</B>
-                     option.  The default is defcolor.
-
-              <B>-linewidth</B> <I>pixels</I>
-                     Sets the width  of  the  connecting  lines  between  data
-                     points.   If  <I>pixels</I>  is  0,  no connecting lines will be
-                     drawn between symbols.  The default is 0.
-
-              <B>-offdash</B> <I>color</I>
-                     Sets the color of the stripes when traces are dashed (see
-                     the <B>-dashes</B> option).  If <I>color</I> is "", then the "off" pix-
-                     els will represent gaps instead of stripes.  If <I>color</I>  is
-                     defcolor,  then  the color will be the same as the <B>-color</B>
-                     option.  The default is defcolor.
-
-              <B>-outline</B> <I>color</I>
-                     Sets the color or the outline  around  each  symbol.   If
-                     <I>color</I>  is  "", then no outline is drawn. If <I>color</I> is def-
-                     color, then the color will be  the  same  as  the  <B>-color</B>
-                     option.  The default is defcolor.
-
-              <B>-outlinewidth</B> <I>pixels</I>
-                     Sets  the width of the outline bordering each symbol.  If
-                     <I>pixels</I> is 0, no outline will be drawn. The default is  1.
-
-              <B>-pixels</B> <I>pixels</I>
-                     Sets  the  size  of  symbols.  If <I>pixels</I> is 0, no symbols
-                     will be drawn.  The default is 0.125i.
-
-              <B>-symbol</B> <I>symbol</I>
-                     Specifies the symbol for  data  points.   <I>Symbol</I>  can  be
-                     either  square,  circle,  diamond,  plus,  cross,  splus,
-                     scross, triangle, "" (where no symbol  is  drawn),  or  a
-                     bitmap.   Bitmaps are specified as "<I>source</I> ?<I>mask</I>?", where
-                     <I>source</I> is the name of the bitmap, and <I>mask</I>  is  the  bit-
-                     map's optional mask.  The default is circle.
-
-              Creates a new pen by the name <I>penName</I>.  No pen by the same  name
-              can  already  exist.  <I>Option</I> and <I>value</I> are described in above in
-              the pen <B>configure</B> operation.

-       <I>pathName</I> <B>pen</B> <B>delete</B> ?<I>penName</I>?...
-              Deletes the named pens. A pen is not really deleted until it  is
-              not  longer  in  use, so it's safe to delete pens mapped to ele-
-              ments.
-
-       <I>pathName</I> <B>pen</B> <B>names</B> ?<I>pattern</I>?...
-              Returns a list of pens matching zero or more  patterns.   If  no
-              <I>pattern</I> argument is give, the names of all pens are returned.
-
-   <B>POSTSCRIPT</B> <B>COMPONENT</B>
-       The  graph can generate encapsulated PostScript output.  There are sev-
-       eral configuration options you can specify to control how the plot will
-       be  generated.   You  can  change the page dimensions and borders.  The
-       plot itself can be scaled, centered,  or  rotated  to  landscape.   The
-       PostScript output can be written directly to a file or returned through
-       the interpreter.
-
-       The following postscript operations are available.
-
-       <I>pathName</I> <B>postscript</B> <B>cget</B> <I>option</I>
-              Returns the current value of  the  postscript  option  given  by
-              <I>option</I>.   <I>Option</I> may be any option described below for the post-
-              script <B>configure</B> operation.
-
-       <I>pathName</I> <B>postscript</B> <B>configure</B> ?<I>option</I> <I>value</I>?...
-              Queries or modifies the  configuration  options  for  PostScript
-              generation.   If  <I>option</I>  isn't specified, a list describing the
-              current postscript options for <I>pathName</I> is returned.  If  <I>option</I>
-              is  specified,  but  not <I>value</I>, then a list describing <I>option</I> is
-              returned.  If one or more <I>option</I> and <I>value</I> pairs are  specified,
-              then  for  each  pair,  the  postscript  option <I>option</I> is set to
-              <I>value</I>.  The following postscript options are available.
-
-              <B>-center</B> <I>boolean</I>
-                     Indicates whether the plot  should  be  centered  on  the
-                     PostScript  page.   If <I>boolean</I> is false, the plot will be
-                     placed in the upper left corner of the page.  The default
-                     is 1.
-
-              <B>-colormap</B> <I>varName</I>
-                     <I>VarName</I>  must be the name of a global array variable that
-                     specifies a color mapping from the X color name to  Post-
-                     Script.   Each  element  of <I>varName</I> must consist of Post-
-                     Script code to set a particular color value  (e.g.  ``1.0
-                     1.0  0.0  setrgbcolor'').  When generating color informa-
-                     tion in PostScript, the array variable <I>varName</I> is checked
-                     if  an element of the name as the color exists. If so, it
-                     uses its value as  the  PostScript  command  to  set  the
-                     Script.   Each  element  of <I>varName</I> must consist of a Tcl
-                     list with one or two elements; the name and point size of
-                     a  PostScript  font.  When outputting PostScript commands
-                     for a particular font,  the  array  variable  <I>varName</I>  is
-                     checked  to  see  if  an  element  by  the specified font
-                     exists.  If there is  such  an  element,  then  the  font
-                     information  contained  in  that  element  is used in the
-                     PostScript output.  (If the point size  is  omitted  from
-                     the  list, the point size of the X font is used).  Other-
-                     wise the X font is examined in an attempt to  guess  what
-                     PostScript  font to use.  This works only for fonts whose
-                     foundry property is  <I>Adobe</I>  (such  as  Times,  Helvetica,
-                     Courier,  etc.).   If  all  of  this  fails then the font
-                     defaults to Helvetica-Bold.
-
-              <B>-decorations</B> <I>boolean</I>
-                     Indicates whether PostScript commands to  generate  color
-                     backgrounds  and  3-D borders will be output.  If <I>boolean</I>
-                     is false, the background will be white and no 3-D borders
-                     will be generated. The default is 1.
-
-              <B>-height</B> <I>pixels</I>
-                     Sets  the  height  of  the plot.  This lets you print the
-                     graph with a height different from the one drawn  on  the
-                     screen.   If  <I>pixels</I>  is 0, the height is the same as the
-                     widget's height.  The default is 0.
-
-              <B>-landscape</B> <I>boolean</I>
-                     If <I>boolean</I> is true, this specifies the printed area is to
-                     be  rotated 90 degrees.  In non-rotated output the X-axis
-                     of the printed area runs along the short dimension of the
-                     page  (``portrait''  orientation);  in rotated output the
-                     X-axis runs along the long dimension of the page (``land-
-                     scape'' orientation).  Defaults to 0.
-
-              <B>-maxpect</B> <I>boolean</I>
-                     Indicates  to  scale  the plot so that it fills the Post-
-                     Script page.  The aspect ratio  of  the  graph  is  still
-                     retained.  The default is 0.
-
-              <B>-padx</B> <I>pad</I>
-                     Sets  the  horizontal padding for the left and right page
-                     borders.  The borders are exterior to the plot.  <I>Pad</I>  can
-                     be a list of one or two screen distances.  If <I>pad</I> has two
-                     elements, the left border is padded by the first distance
-                     and  the right border by the second.  If <I>pad</I> has just one
-                     distance, both the left  and  right  borders  are  padded
-                     evenly.  The default is 1i.
-
-              <B>-pady</B> <I>pad</I>
-                     Sets  the  vertical  padding  for the top and bottom page
-                     borders. The borders are exterior to the plot.   <I>Pad</I>  can
-                     The default width is 8.5i.
-
-              <B>-width</B> <I>pixels</I>
-                     Sets  the  width  of  the plot.  This lets you generate a
-                     plot of a width different from that of  the  widget.   If
-                     <I>pixels</I> is 0, the width is the same as the widget's width.
-                     The default is 0.
-
-              Postscript configuration options may  be  also  be  set  by  the
-              <B>option</B>  command.  The resource name and class are postscript and
-              Postscript respectively.  option  add  *Graph.postscript.Decora-
-              tions false option add *Graph.Postscript.Landscape   true
-
-       <I>pathName</I> <B>postscript</B> <B>output</B> ?<I>fileName</I>? ?<I>option</I> <I>value</I>?...
-              Outputs  a file of encapsulated PostScript.  If a <I>fileName</I> argu-
-              ment isn't present, the command returns the PostScript.  If  any
-              <I>option-value</I>  pairs  are present, they set configuration options
-              controlling how the PostScript is generated.  <I>Option</I>  and  <I>value</I>
-              can  be  anything accepted by the postscript <B>configure</B> operation
-              above.
-
-   <B>MARKER</B> <B>COMPONENTS</B>
-       Markers are simple drawing procedures used  to  annotate  or  highlight
-       areas of the graph.  Markers have various types: text strings, bitmaps,
-       images, connected lines, windows, or polygons.  They can be  associated
-       with  a  particular  element, so that when the element is hidden or un-
-       hidden, so is the marker.  By  default,  markers  are  the  last  items
-       drawn,  so  that  data  elements  will  appear in behind them.  You can
-       change this by configuring the <B>-under</B> option.
-
-       Markers, in contrast to elements, don't affect the scaling of the coor-
-       dinate axes.  They can also have <I>elastic</I> coordinates (specified by -Inf
-       and Inf respectively) that translate into the minimum or maximum  limit
-       of  the axis.  For example, you can place a marker so it always remains
-       in the lower left corner of the plotting area, by using the coordinates
-       -Inf,-Inf.
-
-       The following operations are available for markers.
-
-       <I>pathName</I> <B>marker</B> <B>after</B> <I>markerId</I> ?<I>afterId</I>?
-              Changes the order of the markers, drawing the first marker after
-              the second.  If no second <I>afterId</I>  argument  is  specified,  the
-              marker  is  placed at the end of the display list.  This command
-              can be used to control how markers are displayed  since  markers
-              are drawn in the order of this display list.
-
-       <I>pathName</I> <B>marker</B> <B>before</B> <I>markerId</I> ?<I>beforeId</I>?
-              Changes  the  order  of  the  markers,  drawing the first marker
-              before the second.  If no second <I>beforeId</I> argument is specified,
-              the marker is placed at the beginning of the display list.  This
-              command can be used to control how markers are  displayed  since
-              markers are drawn in the order of this display list.
-              with  <I>tagName</I>  and  <I>sequence</I> (it's an error occurs if there's no
-              such binding) is returned.  If both  <I>command</I>  and  <I>sequence</I>  are
-              missing  then  a list of all the event sequences for which bind-
-              ings have been defined for <I>tagName</I>.
-
-       <I>pathName</I> <B>marker</B> <B>cget</B> <I>option</I>
-              Returns the current value of  the  marker  configuration  option
-              given  by  <I>option</I>.   <I>Option</I> may be any option described below in
-              the <B>configure</B> operation.
-
-       <I>pathName</I> <B>marker</B> <B>configure</B> <I>markerId</I> ?<I>option</I> <I>value</I>?...
-              Queries or modifies the configuration options for  markers.   If
-              <I>option</I>  isn't  specified,  a list describing the current options
-              for <I>markerId</I> is returned.   If  <I>option</I>  is  specified,  but  not
-              <I>value</I>,  then  a  list  describing <I>option</I> is returned.  If one or
-              more <I>option</I> and <I>value</I> pairs are specified, then for  each  pair,
-              the marker option <I>option</I> is set to <I>value</I>.
-
-              The  following  options are valid for all markers.  Each type of
-              marker  also  has  its  own  type-specific  options.   They  are
-              described in the sections below.
-
-              <B>-bindtags</B> <I>tagList</I>
-                     Specifies  the binding tags for the marker.  <I>TagList</I> is a
-                     list of binding tag names.  The tags and their order will
-                     determine  how  events for markers are handled.  Each tag
-                     in the list matching the current event sequence will have
-                     its  Tcl  command  executed.   Implicitly the name of the
-                     marker is always the first tag in the list.  The  default
-                     value is all.
-
-              <B>-coords</B> <I>coordList</I>
-                     Specifies  the coordinates of the marker.  <I>CoordList</I> is a
-                     list of graph coordinates.   The  number  of  coordinates
-                     required  is  dependent  on  the  type  of marker.  Text,
-                     image, and window markers need only two  coordinates  (an
-                     X-Y  coordinate).   Bitmap markers can take either two or
-                     four coordinates (if four, they represent the corners  of
-                     the bitmap). Line markers need at least four coordinates,
-                     polygons at least six.  If <I>coordList</I> is  "",  the  marker
-                     will not be displayed.  The default is "".
-
-              <B>-element</B> <I>elemName</I>
-                     Links  the  marker with the element <I>elemName</I>.  The marker
-                     is drawn only if the element is also currently  displayed
-                     (see  the  element's <B>show</B> operation).  If <I>elemName</I> is "",
-                     the marker is always drawn.  The default is "".
-
-              <B>-hide</B> <I>boolean</I>
-                     Indicates whether the marker  is  drawn.  If  <I>boolean</I>  is
-                     true, the marker is not drawn.  The default is no.
-
-              <B>-under</B> <I>boolean</I>
-                     Indicates whether the marker is  drawn  below/above  data
-                     elements.   If  <I>boolean</I>  is  true, the marker is be drawn
-                     underneath the data element symbols  and  lines.   Other-
-                     wise,  the  marker  is  drawn on top of the element.  The
-                     default is 0.
-
-              <B>-xoffset</B> <I>pixels</I>
-                     Specifies a screen distance to offset the marker horizon-
-                     tally.   <I>Pixels</I>  is a valid screen distance, such as 2 or
-                     1.2i.  The default is 0.
-
-              <B>-yoffset</B> <I>pixels</I>
-                     Specifies a screen distance to offset the markers  verti-
-                     cally.   <I>Pixels</I>  is a valid screen distance, such as 2 or
-                     1.2i.  The default is 0.
-
-              Marker configuration options may also be set by the <B>option</B>  com-
-              mand.   The resource class is either BitmapMarker,  ImageMarker,
-              LineMarker, PolygonMarker, TextMarker, or WindowMarker,  depend-
-              ing on the type of marker.  The resource name is the name of the
-              marker.  option add  *Graph.TextMarker.Foreground  white  option

-
-       <I>pathName</I> <B>marker</B> <B>create</B> <I>type</I> ?<I>option</I> <I>value</I>?...
-              Creates a marker of the selected type. <I>Type</I> may be either  text,
-              line,  bitmap,  image, polygon, or window.  This command returns
-              the marker identifier, used as  the  <I>markerId</I>  argument  in  the
-              other  marker-related  commands.   If  the <B>-name</B> option is used,
-              this overrides the normal marker identifier.  If the  name  pro-
-              vided  is  already  used for another marker, the new marker will
-              replace the old.
-
-       <I>pathName</I> <B>marker</B> <B>delete</B> ?<I>name</I>?...
-              Removes one of more markers.  The graph  will  automatically  be
-              redrawn without the marker..
-
-       <I>pathName</I> <B>marker</B> <B>exists</B> <I>markerId</I>
-              Returns 1 if the marker <I>markerId</I> exists and 0 otherwise.
-
-       <I>pathName</I> <B>marker</B> <B>names</B> ?<I>pattern</I>?
-              Returns  the  names of all the markers that currently exist.  If
-              <I>pattern</I> is supplied, only those markers  whose  names  match  it
-              will be returned.
-
-       <I>pathName</I> <B>marker</B> <B>type</B> <I>markerId</I>
-              Returns  the  type of the marker given by <I>markerId</I>, such as line
-              or text.  If <I>markerId</I> is not a valid a marker identifier, ""  is
-              returned.
-
-   <B>BITMAP</B> <B>MARKERS</B>
-       The following options are specific to bitmap markers:
-
-       <B>-background</B> <I>color</I>
-              Same as the <B>-fill</B> option.
-
-       <B>-bitmap</B> <I>bitmap</I>
-              Specifies  the  bitmap  to  be  displayed.  If <I>bitmap</I> is "", the
-              marker will not be displayed.  The default is "".
-
-       <B>-fill</B> <I>color</I>
-              Sets the background color of the bitmap.  If <I>color</I> is the  empty
-              string,  no  background  will be transparent.  The default back-
-              ground color is "".
-
-       <B>-foreground</B> <I>color</I>
-              Same as the <B>-outline</B> option.
-
-       <B>-mask</B> <I>mask</I>
-              Specifies a mask for the bitmap to be displayed. This mask is  a
-              bitmap  itself,  denoting  the  pixels that are transparent.  If
-              <I>mask</I> is "", all pixels of the bitmap will be drawn.  The default
-              is "".
-
-       <B>-outline</B> <I>color</I>
-              Sets  the  foreground  color of the bitmap. The default value is
-              black.
-
-       <B>-rotate</B> <I>theta</I>
-              Sets the rotation of the bitmap.  <I>Theta</I> is a real number  repre-
-              senting  the  angle of rotation in degrees.  The marker is first
-              rotated and then placed according to its anchor  position.   The
-              default rotation is 0.0.
-
-   <B>IMAGE</B> <B>MARKERS</B>
-       A  image  marker displays an image.  Image markers are created with the
-       marker's <B>create</B> operation in the form:  <I>pathName</I>  <B>marker</B>  <B>create</B>  <B>image</B>
-       ?<I>option</I>  <I>value</I>?...   There  may be many <I>option</I>-<I>value</I> pairs, each sets a
-       configuration option for the marker.  These same <I>option</I>-<I>value</I> pairs may
-       be used with the marker's <B>configure</B> operation.
-
-       The following options are specific to image markers:
-
-       <B>-anchor</B> <I>anchor</I>
-              <I>Anchor</I> tells how to position the image relative to the position-
-              ing point for the image. For example, if <I>anchor</I> is  center  then
-              the  image  is  centered  on the point;  if <I>anchor</I> is n then the
-              image will be drawn such that the top center point of the  rect-
-              angular  region occupied by the image will be at the positioning
-              point.  This option defaults to center.
-
-       <B>-image</B> <I>image</I>
-              Specifies the image to be drawn.  If <I>image</I>  is  "",  the  marker
-              gaps  on  the  line.  Each number must be between 1 and 255.  If
-              <I>dashList</I> is "", the marker line will be solid.
-
-       <B>-fill</B> <I>color</I>
-              Sets the background color of the line.  This color is used  with
-              striped  lines  (see the <B>-fdashes</B> option). If <I>color</I> is the empty
-              string, no background color is drawn (the line will  be  dashed,
-              not striped).  The default background color is "".
-
-       <B>-linewidth</B> <I>pixels</I>
-              Sets the width of the lines.  The default width is 0.
-
-       <B>-outline</B> <I>color</I>
-              Sets  the  foreground  color  of  the line. The default value is
-              black.
-
-       <B>-stipple</B> <I>bitmap</I>
-              Specifies a stipple pattern used to draw the line, rather than a
-              solid  line.   <I>Bitmap</I>  specifies  a bitmap to use as the stipple
-              pattern.  If <I>bitmap</I> is "", then the line is  drawn  in  a  solid
-              fashion. The default is "".
-
-   <B>POLYGON</B> <B>MARKERS</B>
-       A polygon marker displays a closed region described as two or more con-
-       nected line segments.  It is assumed the first and last points are con-
-       nected.   Polygon markers are created using the marker <B>create</B> operation
-       in the form: <I>pathName</I> <B>marker</B> <B>create</B> <B>polygon</B>  ?<I>option</I>  <I>value</I>?...   There
-       may  be  many  <I>option</I>-<I>value</I> pairs, each sets a configuration option for
-       the marker.  These same <I>option</I>-<I>value</I> pairs may be used with the  <B>marker</B>
-       <B>configure</B>  command to change the marker's configuration.  The following
-       options are supported for polygon markers:
-
-       <B>-dashes</B> <I>dashList</I>
-              Sets the dash style of the outline of the polygon. <I>DashList</I> is a
-              list  of up to 11 numbers that alternately represent the lengths
-              of the dashes and gaps on the  outline.   Each  number  must  be
-              between  1  and  255.  If  <I>dashList</I> is "", the outline will be a
-              solid line.
-
-       <B>-fill</B> <I>color</I>
-              Sets the fill color of the polygon.  If <I>color</I> is  "",  then  the
-              interior of the polygon is transparent.  The default is white.
-
-       <B>-linewidth</B> <I>pixels</I>
-              Sets the width of the outline of the polygon. If <I>pixels</I> is zero,
-              no outline is drawn. The default is 0.
-
-       <B>-outline</B> <I>color</I>
-              Sets the color of the outline of the polygon.  If the polygon is
-              stippled  (see  the  <B>-stipple</B>  option), then this represents the
-              foreground color of the stipple.  The default is black.
-
-       the marker's <B>configure</B> operation.
-
-       The following options are specific to text markers:
-
-       <B>-anchor</B> <I>anchor</I>
-              <I>Anchor</I> tells how to position the text relative to the  position-
-              ing  point  for  the text. For example, if <I>anchor</I> is center then
-              the text is centered on the point; if <I>anchor</I> is n then the  text
-              will  be drawn such that the top center point of the rectangular
-              region occupied by the text will be at  the  positioning  point.
-              This default is center.
-
-       <B>-background</B> <I>color</I>
-              Same as the <B>-fill</B> option.
-
-       <B>-font</B> <I>fontName</I>
-              Specifies  the  font  of  the text.  The default is *-Helvetica-
-              Bold-R-Normal-*-120-*.
-
-       <B>-fill</B> <I>color</I>
-              Sets the background color of the text.  If <I>color</I>  is  the  empty
-              string,  no  background  will be transparent.  The default back-
-              ground color is "".
-
-       <B>-foreground</B> <I>color</I>
-              Same as the <B>-outline</B> option.
-
-       <B>-justify</B> <I>justify</I>
-              Specifies how the text should be justified.  This  matters  only
-              when  the  marker  contains  more than one line of text. <I>Justify</I>
-              must be left, right, or center.  The default is center.
-
-       <B>-outline</B> <I>color</I>
-              Sets the color of the text. The default value is black.
-
-       <B>-padx</B> <I>pad</I>
-              Sets the padding to the left and right exteriors  of  the  text.
-              <I>Pad</I>  can  be  a list of one or two screen distances.  If <I>pad</I> has
-              two elements, the left side of the text is padded by  the  first
-              distance  and the right side by the second.  If <I>pad</I> has just one
-              distance, both the left and right sides are padded evenly.   The
-              default is 4.
-
-       <B>-pady</B> <I>pad</I>
-              Sets the padding above and below the text.  <I>Pad</I> can be a list of
-              one or two screen distances.  If <I>pad</I> has two elements, the  area
-              above  the  text  is  padded  by the first distance and the area
-              below by the second.  If <I>pad</I> is just one distance, both the  top
-              and bottom areas are padded evenly.  The default is 4.
-
-       <B>-rotate</B> <I>theta</I>
-              Specifies  the number of degrees to rotate the text.  <I>Theta</I> is a
-
-       <I>option</I>-<I>value</I> pairs may be used with the marker's <B>configure</B> command.
-
-       The following options are specific to window markers:
-
-       <B>-anchor</B> <I>anchor</I>
-              <I>Anchor</I> tells how to position the widget relative  to  the  posi-
-              tioning  point  for the widget. For example, if <I>anchor</I> is center
-              then the widget is centered on the point; if <I>anchor</I>  is  n  then
-              the  widget  will be displayed such that the top center point of
-              the rectangular region occupied by the widget  will  be  at  the
-              positioning point.  This option defaults to center.
-
-       <B>-height</B> <I>pixels</I>
-              Specifies  the height to assign to the marker's window.  If this
-              option isn't specified, or if it is specified as  "",  then  the
-              window  is given whatever height the widget requests internally.
-
-       <B>-width</B> <I>pixels</I>
-              Specifies the width to assign to the marker's window.   If  this
-              option  isn't  specified,  or if it is specified as "", then the
-              window is given whatever width the widget requests internally.
-
-       <B>-window</B> <I>pathName</I>
-              Specifies the widget to be managed by the graph.  <I>PathName</I>  must
-              be a child of the <B>graph</B> widget.

-<H2>GRAPH COMPONENT BINDINGS</H2><PRE>
-       Specific  graph  components,  such  as  elements,  markers  and  legend
-       entries, can have a command trigger when event  occurs  in  them,  much
-       like  canvas  items in Tk's canvas widget.  Not all event sequences are
-       valid.  The only binding events that may be specified are those related
-       to  the  mouse and keyboard (such as <B>Enter</B>, <B>Leave</B>, <B>ButtonPress</B>, <B>Motion</B>,
-       and <B>KeyPress</B>).
-
-       Only one element or marker can be picked during an event.  This  means,
-       that  if  the mouse is directly over both an element and a marker, only
-       the uppermost component  is  selected.   This  isn't  true  for  legend
-       entries.   Both  a legend entry and an element (or marker) binding com-
-       mands will be invoked if both items are picked.
-
-       It is possible for multiple bindings to match a particular event.  This
-       could occur, for example, if one binding is associated with the element
-       name and another is associated with one of the element's tags (see  the
-       <B>-bindtags</B>  option).  When this occurs, all of the matching bindings are
-       invoked.  A binding associated with the element name is invoked  first,
-       followed  by  one binding for each of the element's bindtags.  If there
-       are multiple matching bindings for a single tag,  then  only  the  most
-       specific  binding  is  invoked.  A continue command in a binding script
-       terminates that script, and a break command terminates that script  and
-       skips  any  remaining  scripts for the event, just as for the bind com-
-       mand.
-
-       vectors are updated.
-
-       From  Tcl,  create  the  vectors and configure the element to use them.
-       vector X Y .g element configure line1 -xdata X -ydata  Y  To  set  data
-       points  from  C,  you  pass  the  values as arrays of doubles using the
-       <B>Blt_ResetVector</B> call.  The vector is reset with the new data and at the
-       next  idle  point (when Tk re-enters its event loop), the graph will be
-       redrawn automatically.  #include &lt;tcl.h&gt; #include &lt;blt.h&gt;
-
-       register int i; Blt_Vector *xVec, *yVec; double x[50], y[50];
-
-       /* Get the BLT vectors "X" and "Y"  (created  above  from  Tcl)  */  if
-       ((Blt_GetVector(interp, "X", &amp;xVec) != TCL_OK) ||
-           (Blt_GetVector(interp, "Y", &amp;yVec) != TCL_OK)) {
-           return TCL_ERROR; }
-
-       for (i = 0; i &lt; 50; i++) {
-           x[i] = i * 0.02;
-           y[i] = sin(x[i]); }
-
-       /*  Put  the data into BLT vectors */ if ((Blt_ResetVector(xVec, x, 50,
-       50, TCL_VOLATILE) != TCL_OK) ||
-           (Blt_ResetVector(yVec, y, 50, 50, TCL_VOLATILE) != TCL_OK)) {
-          return TCL_ERROR; } See the <B>vector</B> manual page for more details.

-<H2>SPEED TIPS</H2><PRE>
-       There may be cases where the graph needs to be  drawn  and  updated  as
-       quickly  as possible.  If drawing speed becomes a big problem, here are
-       a few tips to speed up displays.
-
-       <B>o</B> Try to minimize the number of data points.  The more data points  the
-         looked at, the more work the graph must do.
-
-       <B>o</B> If your data is generated as floating point values, the time required
-         to convert the data values to and from ASCII strings can be  signifi-
-         cant,  especially when there any many data points.  You can avoid the
-         redundant string-to-decimal conversions using the C API to  BLT  vec-
-         tors.
-
-       <B>o</B> Data  elements  without  symbols  are drawn faster than with symbols.
-         Set the data element's <B>-symbol</B> option to none.  If you need  to  draw
-         symbols, try using the simple symbols such as splus and scross.
-
-       <B>o</B> Don't stipple or dash the element.  Solid lines are much faster.
-
-       <B>o</B> If  you update data elements frequently, try turning off the widget's
-         <B>-bufferelements</B> option.  When the graph is first displayed, it  draws
-         data  elements  into an internal pixmap.  The pixmap acts as a cache,
-         so that when the graph needs to be redrawn again, and the  data  ele-
-         ments or coordinate axes haven't changed, the pixmap is simply copied
-         to the screen.  This is especially useful when you are using  markers
-         to  highlight  points  and regions on the graph.  But if the graph is

-.SH NAME
-graph \-  2D graph for plotting X\-Y coordinate data.
-.SH SYNOPSIS
-\fBgraph\fI \fIpathName \fR?\fIoption value\fR?...
-.BE
-.SH DESCRIPTION
-The \fBgraph\fR command creates a graph for plotting
-two-dimensional data (X\-Y coordinates). It has many configurable
-components: coordinate axes, elements, legend, grid lines, cross
-hairs, etc.  They allow you to customize the look and feel of the
-graph.
-.SH INTRODUCTION
-The \fBgraph\fR command creates a new window for plotting
-two-dimensional data (X\-Y coordinates).  Data points are plotted in a
-rectangular area displayed in the center of the new window.  This is the
-\fIplotting area\fR.  The coordinate axes are drawn in the
-margins around the plotting area.  By default, the legend is displayed
-in the right margin.  The title is displayed in top margin.
-.PP
-The \fBgraph\fR widget is composed of several components: coordinate
-axes, data elements, legend, grid, cross hairs, pens, postscript, and
-annotation markers.
-.TP 1i
-\f(CWaxis\fR 
-The graph has four standard axes (\f(CWx\fR, \f(CWx2\fR,
-\f(CWy\fR, and \f(CWy2\fR), but you can create and display any number 
-of axes.  Axes control what region of data is
-displayed and how the data is scaled. Each axis consists of the axis
-line, title, major and minor ticks, and tick labels.  Tick labels
-display the value at each major tick.
-.TP 1i
-\f(CWcrosshairs\fR 
-Cross hairs are used to position the mouse pointer relative to the X
-and Y coordinate axes. Two perpendicular lines, intersecting at the
-current location of the mouse, extend across the plotting area to the
-coordinate axes.
-.TP 1i
-\f(CWelement\fR 
-An element represents a set of data points. Elements can be plotted 
-with a symbol at each data point and lines connecting the points. 
-The appearance of the element, such as its symbol, line width, and 
-color is configurable.
-.TP 1i
-\f(CWgrid\fR
-Extends the major and minor ticks of the X\-axis and/or Y\-axis across the 
-plotting area. 
-.TP 1i
-\f(CWlegend\fR 
-The legend displays the name and symbol of each data element. 
-The legend can be drawn in any margin or in the plotting area.
-.TP 1i
-\f(CWmarker\fR
-Markers are used annotate or highlight areas of the graph. For 
-example, you could use a polygon marker to fill an area under a 
-curve, or a text marker to label a particular data point. Markers 
-come in various forms: text strings, bitmaps, connected line 
-segments, images, polygons, or embedded widgets.
-.TP 1i
-\f(CWpen\fR 
-Pens define attributes (both symbol and line style) for elements. 
-Data elements use pens to specify how they should be drawn.  A data 
-element may use many pens at once.  Here, the particular pen 
-used for a data point is determined from each element's weight 
-vector (see the element's \fB\-weight\fR and \fB\-style\fR options).  
-.TP 1i
-\f(CWpostscript\fR
-The widget can generate encapsulated PostScript output. This component
-has several options to configure how the PostScript is generated.
-.SH SYNTAX
-.DS
-\fBgraph \fIpathName \fR?\fIoption value\fR?...
-.DE
-The \fBgraph\fR command creates a new window \fIpathName\fR and makes
-it into a \fBgraph\fR widget.  At the time this command is invoked, there
-must not exist a window named \fIpathName\fR, but \fIpathName\fR's
-parent must exist.  Additional options may be specified on the
-command line or in the option database to configure aspects of the
-graph such as its colors and font.  See the \fBconfigure\fR operation
-below for the exact details about what \fIoption\fR and \fIvalue\fR
-pairs are valid.
-.PP
-If successful, \fBgraph\fR returns the path name of the widget.  It
-also creates a new Tcl command by the same name.  You can use this
-command to invoke various operations that query or modify the graph.
-The general form is:
-.DS
-\fIpathName \fIoperation\fR \fR?\fIarg\fR?...
-.DE
-Both \fIoperation\fR and its arguments determine the exact behavior of
-the command.  The operations available for the graph are described in 
-the 
-.SB "GRAPH OPERATIONS"
-section.
-.PP
-The command can also be used to access components of the graph.
-.DS
-\fIpathName component operation\fR ?\fIarg\fR?...
-.DE
-The operation, now located after the name of the component, is the
-function to be performed on that component. Each component has its own
-set of operations that manipulate that component.  They will be
-described below in their own sections.
-.SH EXAMPLE
-The \fBgraph\fR command creates a new graph.  
-.CS
-# Create a new graph.  Plotting area is black.
-graph .g \-plotbackground black
-.CE
-A new Tcl command \f(CW.g\fR is also created.  This command can be used
-to query and modify the graph.  For example, to change the title of
-the graph to "My Plot", you use the new command and the graph's
-\fBconfigure\fR operation.
-.CS
-# Change the title.
-\&.g configure \-title "My Plot"
-.CE
-A graph has several components. To access a particular component you
-use the component's name. For example, to add data elements, you use
-the new command and the \fBelement\fR component.
-.CS
-# Create a new element named "line1"

-An element named \f(CWe1\fR is now created in \f(CW.b\fR.  It 
-is automatically added to the display list of elements.  You can
-use this list to control in what order elements are displayed.
-To query or reset the element display list, you use the element's 
-\fBshow\fR operation.
-.CS
-# Get the current display list 
-set elemList [.b element show]
-# Remove the first element so it won't be displayed.
-\&.b element show [lrange $elemList 0 end]
-.CE
-The element will be displayed by as many bars as there are data points
-(in this case there are ten).  The bars will be drawn centered at the
-x-coordinate of the data point.  All the bars will have the same
-attributes (colors, stipple, etc).  The width of each bar is by
-default one unit.  You can change this with using the \fB\-barwidth\fR

-An element named \f(CWline1\fR is now created in \f(CW.g\fR.  By
-default, the element's label in the legend will be also \f(CWline1\fR.
-You can change the label, or specify no legend entry, again using the
-element's \fBconfigure\fR operation.
-.CS
-# Don't display "line1" in the legend.
-\&.g element configure line1 \-label ""
-.CE
-You can configure more than just the element's label.  An element has
-many attributes such as symbol type and size, dashed or solid lines,
-colors, line width, etc.
-.CS
-\&.g element configure line1 \-symbol square \-color red \\
-	\-dashes { 2 4 2 } \-linewidth 2 \-pixels 2c
-.CE
-Four coordinate axes are automatically created: \f(CWx\fR, \f(CWx2\fR,
-\f(CWy\fR, and \f(CWy2\fR.  And by default, elements are mapped onto the
-axes \f(CWx\fR and \f(CWy\fR.  This can be changed with the \fB\-mapx\fR
-and \fB\-mapy\fR options.
-.CS
-# Map "line1" on the alternate Y\-axis "y2".
-\&.g element configure line1 \-mapy y2
-.CE
-Axes can be configured in many ways too.  For example, you change the
-scale of the Y\-axis from linear to log using the \fBaxis\fR component.
-.CS
-# Y\-axis is log scale.
-\&.g axis configure y \-logscale yes
-.CE
-One important way axes are used is to zoom in on a particular data
-region.  Zooming is done by simply specifying new axis limits using
-the \fB\-min\fR and \fB\-max\fR configuration options.
-.CS
-\&.g axis configure x \-min 1.0 \-max 1.5
-\&.g axis configure y \-min 12.0 \-max 55.15
-.CE
-To zoom interactively, you link the \fBaxis configure\fR operations with
-some user interaction (such as pressing the mouse button), using the
-\fBbind\fR command.  To convert between screen and graph coordinates,
-use the \fBinvtransform\fR operation.
-.CS
-# Click the button to set a new minimum 
-bind .g <ButtonPress-1> { 
-    %W axis configure x \-min [%W axis invtransform x %x]
-    %W axis configure x \-min [%W axis invtransform x %y]
-}
-.CE
-By default, the limits of the axis are determined from data values.
-To reset back to the default limits, set the \fB\-min\fR and
-\fB\-max\fR options to the empty value.
-.CS
-# Reset the axes to autoscale again.
-\&.g axis configure x \-min {} \-max {}
-\&.g axis configure y \-min {} \-max {}
-.CE
-By default, the legend is drawn in the right margin.  You can
-change this or any legend configuration options using the
-\fBlegend\fR component.
-.CS
-# Configure the legend font, color, and relief
-\&.g legend configure \-position left \-relief raised \\
-	\-font fixed \-fg blue
-.CE
-To prevent the legend from being displayed, turn on the \fB\-hide\fR
-option.
-.CS
-# Don't display the legend.
-\&.g legend configure \-hide yes\fR
-.CE
-The \fBgraph\fR widget has simple drawing procedures called markers.
-They can be used to highlight or annotate data in the graph. The types
-of markers available are bitmaps, images, polygons, lines, or windows.
-Markers can be used, for example, to mark or brush points.  In this
-example, is a text marker that labels the data first point.  Markers
-are created using the \fBmarker\fR component.
-.CS
-# Create a label for the first data point of "line1".
-\&.g marker create text \-name first_marker \-coords { 0.2 26.18 } \\
-	\-text "start" \-anchor se \-xoffset -10 \-yoffset -10
-.CE
-This creates a text marker named \f(CWfirst_marker\fR.  It will display
-the text "start" near the coordinates of the first data point.  The
-\fB\-anchor\fR, \fB\-xoffset\fR, and \fB\-yoffset\fR options are used
-to display the marker above and to the left of the data point, so that
-the data point isn't covered by the marker.  By default,
-markers are drawn last, on top of data.  You can change this with the
-\fB\-under\fR option.
-.CS
-# Draw the label before elements are drawn.
-\&.g marker configure first_marker \-under yes
-.CE
-You can add cross hairs or grid lines using the \fBcrosshairs\fR and
-\fBgrid\fR components.
-.CS
-# Display both cross hairs and grid lines.
-\&.g crosshairs configure \-hide no \-color red
-\&.g grid configure \-hide no \-dashes { 2 2 }
-# Set up a binding to reposition the crosshairs.
-bind .g <Motion> {
-    .g crosshairs configure -position @%x,%y
-}
-.CE
-The crosshairs are repositioned as the mouse pointer is moved
-in the graph.  The pointer X-Y coordinates define the center
-of the crosshairs.
-.PP
-Finally, to get hardcopy of the graph, use the \fBpostscript\fR
-component.
-.CS
-# Print the graph into file "file.ps"
-\&.g postscript output file.ps \-maxpect yes \-decorations no
-.CE
-This generates a file \f(CWfile.ps\fR containing the encapsulated
-PostScript of the graph.  The option \fB\-maxpect\fR says to scale the
-plot to the size of the page.  Turning off the \fB\-decorations\fR
-option denotes that no borders or color backgrounds should be
-drawn (i.e. the background of the margins, legend, and plotting
-area will be white).

-.SH "GRAPH COMPONENTS"
-A graph is composed of several components: coordinate axes, data
-elements, legend, grid, cross hairs, postscript, and annotation
-markers. Instead of one big set of configuration options and
-operations, the graph is partitioned, where each component has its own
-configuration options and operations that specifically control that
-aspect or part of the graph. 
-.SS "AXIS COMPONENTS"
-Four coordinate axes are automatically created: two X\-coordinate axes
-(\f(CWx\fR and \f(CWx2\fR) and two Y\-coordinate axes (\f(CWy\fR, and
-\f(CWy2\fR).  By default, the axis \f(CWx\fR is located in the bottom
-margin, \f(CWy\fR in the left margin, \f(CWx2\fR in the top margin, and
-\f(CWy2\fR in the right margin.
-.PP
-An axis consists of the axis line, title, major and minor ticks, and
-tick labels.  Major ticks are drawn at uniform intervals along the
-axis.  Each tick is labeled with its coordinate value.  Minor ticks
-are drawn at uniform intervals within major ticks.  
-.PP
-The range of the axis controls what region of data is plotted.
-Data points outside the minimum and maximum limits of the axis are
-not plotted.  By default, the minimum and maximum limits are
-determined from the data, but you can reset either limit.
-.PP
-You can have several axes. To create an axis, invoke
-the axis component and its create operation.
-.CS
-# Create a new axis called "tempAxis"
-\&.g axis create tempAxis
-.CE
-You map data elements to an axis using the element's \-mapy and \-mapx
-configuration options. They specify the coordinate axes an element
-is mapped onto.
-.CS
-# Now map the tempAxis data to this axis.
-\&.g element create "e1" \-xdata $x \-ydata $y \-mapy tempAxis
-.CE
-Any number of axes can be displayed simultaneously. They are drawn in
-the margins surrounding the plotting area.  The default axes \f(CWx\fR
-and \f(CWy\fR are drawn in the bottom and left margins. The axes
-\f(CWx2\fR and \f(CWy2\fR are drawn in top and right margins.  By
-default, only \f(CWx\fR and \f(CWy\fR are shown. Note that the axes
-can have different scales.
-.PP
-To display a different axis or more than one axis, you invoke one of
-the following components: \fBxaxis\fR, \fByaxis\fR, \fBx2axis\fR, and
-\fBy2axis\fR.  Each component has a \fBuse\fR operation that
-designates the axis (or axes) to be drawn in that corresponding
-margin: \fBxaxis\fR in the bottom, \fByaxis\fR in the left,
-\fBx2axis\fR in the top, and \fBy2axis\fR in the right.
-.CS
-# Display the axis tempAxis in the left margin.
-\&.g yaxis use tempAxis
-.CE
-The \fBuse\fR operation takes a list of axis names as its last
-argument.  This is the list of axes to be drawn in this margin.
-.PP
-You can configure axes in many ways. The axis scale can be linear or
-logarithmic.  The values along the axis can either monotonically
-increase or decrease.  If you need custom tick labels, you can specify
-a Tcl procedure to format the label any way you wish.  You can control
-how ticks are drawn, by changing the major tick interval or the number
-of minor ticks.  You can define non-uniform tick intervals, such as
-for time-series plots.
-.PP
-.TP
-\fIpathName \fBaxis bind \fItagName\fR ?\fIsequence\fR?  ?\fIcommand\fR? 
-Associates \fIcommand\fR with \fItagName\fR such that whenever the
-event sequence given by \fIsequence\fR occurs for an axis with this
-tag, \fIcommand\fR will be invoked.  The syntax is similar to the 
-\fBbind\fR command except that it operates on graph axes, rather 
-than widgets. See the \fBbind\fR manual entry for
-complete details on \fIsequence\fR and the substitutions performed on 
-\fIcommand\fR before invoking it.  
-.sp
-If all arguments are specified then a new binding is created, replacing 
-any existing binding for the same \fIsequence\fR and \fItagName\fR.
-If the first character of \fIcommand\fR is \f(CW+\fR then \fIcommand\fR 
-augments an existing binding rather than replacing it. 
-If no \fIcommand\fR argument is provided then the command currently
-associated with \fItagName\fR and \fIsequence\fR (it's an error occurs 
-if there's no such binding) is returned.  If both \fIcommand\fR and 
-\fIsequence\fR are missing then a list of all the event sequences for 
-which bindings have been defined for \fItagName\fR.

-.TP
-\fIpathName \fBaxis \fBconfigure \fIaxisName \fR?\fIaxisName\fR?... ?\fIoption value\fR?...
-Queries or modifies the configuration options of \fIaxisName\fR.
-Several axes can be changed.  If \fIoption\fR isn't specified, a list
-describing all the current options for \fIaxisName\fR is returned.  If
-\fIoption\fR is specified, but not \fIvalue\fR, then a list describing
-\fIoption\fR is returned.  If one or more \fIoption\fR and \fIvalue\fR
-pairs are specified, then for each pair, the axis option \fIoption\fR
-is set to \fIvalue\fR.  The following options are valid for axes.
-.RS
-.TP
-\fB\-bindtags \fItagList\fR
-Specifies the binding tags for the axis.  \fITagList\fR is a list
-of binding tag names.  The tags and their order will determine how
-events for axes are handled.  Each tag in the list matching the current event
-sequence will have its Tcl command executed.  Implicitly the name of

-When outputting PostScript commands for a particular font, the array
-variable \fIvarName\fR is checked to see if an element by the 
-specified font exists.  If there is such an element, then the font
-information contained in that element is used in the PostScript
-output.  (If the point size is omitted from the list, the point size
-of the X font is used).  Otherwise the X font is examined in an
-attempt to guess what PostScript font to use.  This works only for
-fonts whose foundry property is \fIAdobe\fR (such as Times, Helvetica,
-Courier, etc.).  If all of this fails then the font defaults to
-\f(CWHelvetica-Bold\fR.

-.SS "MARKER COMPONENTS"
-Markers are simple drawing procedures used to annotate or highlight
-areas of the graph.  Markers have various types: text strings,
-bitmaps, images, connected lines, windows, or polygons.  They can be
-associated with a particular element, so that when the element is
-hidden or un-hidden, so is the marker.  By default, markers are the
-last items drawn, so that data elements will appear in
-behind them.  You can change this by configuring the \fB\-under\fR
-option.
-.PP
-Markers, in contrast to elements, don't affect the scaling of the
-coordinate axes.  They can also have \fIelastic\fR coordinates
-(specified by \f(CW-Inf\fR and \f(CWInf\fR respectively) that translate
-into the minimum or maximum limit of the axis.  For example, you can
-place a marker so it always remains in the lower left corner of the
-plotting area, by using the coordinates \f(CW-Inf\fR,\f(CW-Inf\fR.
-.PP
-The following operations are available for markers.
-.TP
-\fIpathName \fBmarker after \fImarkerId\fR ?\fIafterId\fR?
-Changes the order of the markers, drawing the first
-marker after the second.  If no second \fIafterId\fR argument is
-specified, the marker is placed at the end of the display list.  This
-command can be used to control how markers are displayed since markers
-are drawn in the order of this display list.
-.TP
-\fIpathName \fBmarker before \fImarkerId\fR ?\fIbeforeId\fR?
-Changes the order of the markers, drawing the first
-marker before the second.  If no second \fIbeforeId\fR argument is
-specified, the marker is placed at the beginning of the display list.
-This command can be used to control how markers are displayed since
-markers are drawn in the order of this display list.
-.TP
-\fIpathName \fBmarker bind \fItagName\fR ?\fIsequence\fR?  ?\fIcommand\fR? 
-Associates \fIcommand\fR with \fItagName\fR such that whenever the
-event sequence given by \fIsequence\fR occurs for a marker with this
-tag, \fIcommand\fR will be invoked.  The syntax is similar to the 
-\fBbind\fR command except that it operates on graph markers, rather 
-than widgets. See the \fBbind\fR manual entry for
-complete details on \fIsequence\fR and the substitutions performed on 
-\fIcommand\fR before invoking it.  
-.sp
-If all arguments are specified then a new binding is created, replacing 
-any existing binding for the same \fIsequence\fR and \fItagName\fR.
-If the first character of \fIcommand\fR is \f(CW+\fR then \fIcommand\fR 
-augments an existing binding rather than replacing it. 
-If no \fIcommand\fR argument is provided then the command currently
-associated with \fItagName\fR and \fIsequence\fR (it's an error occurs 
-if there's no such binding) is returned.  If both \fIcommand\fR and

-events for markers are handled.  Each tag in the list matching the 
-current event sequence will have its Tcl command executed.  Implicitly 
-the name of the marker is always the first tag in the list.
-The default value is \f(CWall\fR.
-.TP
-\fB\-coords \fIcoordList\fR
-Specifies the coordinates of the marker.  \fICoordList\fR is 
-a list of graph coordinates.  The number of coordinates required

-name is invoked first, followed by one binding for each of the element's 
-bindtags.  If there are multiple matching bindings for a single tag, 
-then only the most specific binding is invoked.  A continue command 
-in a binding script terminates that script, and a break command 
-terminates that script and skips any remaining scripts for the event, 
-just as for the bind command.

-.SH SPEED TIPS
-There may be cases where the graph needs to be drawn and updated as
-quickly as possible.  If drawing speed becomes a big
-problem, here are a few tips to speed up displays.
-.TP 2
-\(bu 
-Try to minimize the number of data points.  The more data points
-the looked at, the more work the graph must do.
-.TP 2
-\(bu 
-If your data is generated as floating point values, the time required
-to convert the data values to and from ASCII strings can be
-significant, especially when there any many data points.  You can
-avoid the redundant string-to-decimal conversions using the C API to
-BLT vectors.
-.TP 2
-\(bu
-Data elements without symbols are drawn faster than with symbols.
-Set the data element's \fB\-symbol\fR option to \f(CWnone\fR.  If you need to
-draw symbols, try using the simple symbols such as \f(CWsplus\fR and
-\f(CWscross\fR.
-.TP 2
-\(bu
-Don't stipple or dash the element.  Solid lines are much faster.
-.TP 2
-\(bu 
-If you update data elements frequently, try turning off the
-widget's \fB\-bufferelements\fR option.  When the graph is first
-displayed, it draws data elements into an internal pixmap.  The pixmap
-acts as a cache, so that when the graph needs to be redrawn again, and
-the data elements or coordinate axes haven't changed, the pixmap is
-simply copied to the screen.  This is especially useful when you are
-using markers to highlight points and regions on the graph.  But if
-the graph is updated frequently, changing either the element data or
-coordinate axes, the buffering becomes redundant.
-.SH LIMITATIONS
-Auto-scale routines do not use requested min/max limits as boundaries
-when the axis is logarithmically scaled.
-.PP
-The PostScript output generated for polygons with more than 1500
-points may exceed the limits of some printers (See PostScript Language
-Reference Manual, page 568).  The work-around is to break the polygon
-into separate pieces.

-<H2>DESCRIPTION</H2><PRE>
-       The <B>vector</B> command creates an array of floating point values.  The vec-
-       tor's components can be manipulated in three ways: through a Tcl  array
-       variable, a Tcl command, or the C API.
-

-<H2>INTRODUCTION</H2><PRE>
-       A vector is an ordered set of real numbers.  The components of a vector
-       are indexed by integers.
-
-       Vectors are common data structures for many applications.  For example,
-       a  graph  may  use  two vectors to represent the X-Y coordinates of the
-       data plotted.  The graph will automatically be redrawn when the vectors
-       are  updated or changed. By using vectors, you can separate data analy-
-       sis from the graph widget.  This makes it easier, for example,  to  add
-       data  transformations, such as splines.  It's possible to plot the same
-       data to in multiple graphs, where each graph presents a different  view
-       or scale of the data.
-
-       You  could  try to use Tcl's associative arrays as vectors.  Tcl arrays
-       are easy to use.  You can access individual elements randomly by speci-
-       fying  the  index,  or  the set the entire array by providing a list of
-       index and value pairs for each element.  The disadvantages of  associa-
-       tive  arrays  as  vectors  lie in the fact they are implemented as hash
-       tables.
-
-       <B>o</B> There's no implied ordering to the associative arrays.  If  you  used
-         vectors  for  plotting, you would want to insure the second component
-         comes after the first, an so on.  This isn't  possible  since  arrays
-         are actually hash tables.  For example, you can't get a range of val-
-         ues between two indices.  Nor can you sort an array.
-
-       <B>o</B> Arrays consume lots of memory when the  number  of  elements  becomes
-         large  (tens of thousands).  This is because each element's index and
-         value are stored as strings in the hash table.
-
-       <B>o</B> The C programming interface is unwieldy.  Normally with vectors,  you
-         would  like to view the Tcl array as you do a C array, as an array of
-         floats or doubles.  But with hash tables, you must convert  both  the
-         index  and  value to and from decimal strings, just to access an ele-
-         ment in the array.  This makes it cumbersome to perform operations on
-         the array as a whole.
-
-       The  <B>vector</B>  command  tries to overcome these disadvantages while still
-       0.0.  In addition, both a Tcl command and array variable, both named y,
-       are created.  You can use either the command or variable  to  query  or
-       modify components of the vector.  # Set the first value.  set <B>y(0)</B> 9.25
-       puts "y has [y length] components" The array y can be used to  read  or
-       set individual components of the vector.  Vector components are indexed
-       from zero.  The array index must be a number less than  the  number  of
-       components.  For example, it's an error if you try to set the 51st ele-
-       ment of y.  # This is an error. The vector only has 50 components.  set
-       <B>y(50)</B> 0.02 You can also specify a range of indices using a colon (:) to
-       separate the first and last indices of the range.  # Set the first  six
-       components  of y set y(0:5) 25.2 If you don't include an index, then it
-       will default to the first and/or last component of the vector.  # Print
-       out  all  the  components  of y puts "y = $y(:)" There are special non-
-       numeric indices.  The index end, specifies the last  component  of  the
-       vector.  It's an error to use this index if the vector is empty (length
-       is zero).  The index ++end can be used to extend the vector by one com-
-       ponent  and initialize it to a specific value.  You can't read from the
-       array using this index, though.  # Extend the vector by one  component.
-       set  y(++end)  0.02  The  other  special indices are min and max.  They
-       return the current smallest and largest components of  the  vector.   #
-       Print the bounds of the vector puts "min=$y(min) max=$y(max)" To delete
-       components from a vector, simply unset the corresponding array element.
-       In the following example, the first component of y is deleted.  All the
-       remaining components of y will be moved down by one index as the length
-       of  the  vector  is reduced by one.  # Delete the first component unset
-       <B>y(0)</B> puts "new first element is $<B>y(0)</B>" The  vector's  Tcl  command  can
-       also  be  used to query or set the vector.  # Create and set the compo-
-       nents of a new vector blt::vector create x x set { 0.02 0.04 0.06  0.08
-       0.10 0.12 0.14 0.16 0.18 0.20 } Here we've created a vector x without a
-       initial length specification.  In this case, the length is  zero.   The
-       <B>set</B>  operation  resets  the vector, extending it and setting values for
-       each new component.
-
-       There are several operations for vectors.  The  <B>range</B>  operation  lists
-       the  components of a vector between two indices.  # List the components
-       puts "x = [x range 0 end]" You can search for a particular value  using
-       the  <B>search</B>  operation.  It returns a list of indices of the components
-       with the same value.  If no component has the same  value,  it  returns
-       "".   #  Find  the index of the biggest component set indices [x search
-       $x(max)] Other operations copy,  append,  or  sort  vectors.   You  can
-       append  vectors  or  new values onto an existing vector with the <B>append</B>
-       operation.  # Append assorted vectors and values to x x append x2 x3  {
-       2.3  4.5  }  x4 The <B>sort</B> operation sorts the vector.  If any additional
-       vectors are specified, they are rearranged in the  same  order  as  the
-       vector.   For example, you could use it to sort data points represented
-       by x and y vectors.  # Sort the data points x sort y The  vector  x  is
-       sorted  while  the  components of y are rearranged so that the original
-       x,y coordinate pairs are retained.
-
-       The <B>expr</B> operation lets you perform arithmetic on vectors.  The  result
-       is stored in the vector.  # Add the two vectors and a scalar x expr { x
-       + y } x expr { x * 2 } When a vector is modified, resized, or  deleted,
-       Vectors are created using the <B>vector</B> <B>create</B> operation.  Th <B>create</B> oper-
-       ation can be invoked in one of three forms:
-
-       <B>blt::vector</B> <B>create</B> <I>vecName</I>
-              This  creates a new vector <I>vecName</I> which initially has no compo-
-              nents.
-
-       <B>blt::vector</B> <B>create</B> <I>vecName</I>(<I>size</I>)
-              This second form creates a new vector which  will  contain  <I>size</I>
-              number  of  components.  The components will be indexed starting
-              from zero (0). The default value for the components is 0.0.
-
-       <B>blt::vector</B> <B>create</B> <I>vecName</I>(<I>first</I>:<I>last</I>)
-              The last form creates a new  vector  of  indexed  <I>first</I>  through
-              <I>last</I>.   <I>First</I> and <I>last</I> can be any integer value so long as <I>first</I>
-              is less than <I>last</I>.
-
-       Vector names must start with a letter and consist of  letters,  digits,
-       or  underscores.   #  Error:  must start with letter blt::vector create
-       1abc You can automatically generate vector names using the "#auto" vec-
-       tor  name.   The  <B>create</B>  operation will generate a unique vector name.
-       set vec [blt::vector create #auto] puts "$vec has [$vec length]  compo-
-       nents"
-
-   <B>VECTOR</B> <B>INDICES</B>
-       Vectors  are indexed by integers.  You can access the individual vector
-       components via its array variable or Tcl command.   The  string  repre-
-       senting  the index can be an integer, a numeric expression, a range, or
-       a special keyword.
-
-       The index must lie within the current range of the vector, otherwise an
-       an  error  message  is  returned.  Normally the indices of a vector are
-       start from 0.  But you can use the <B>offset</B> operation to  change  a  vec-
-       tor's  indices  on-the-fly.   puts  $<B>vecName(0)</B>  vecName offset -5 puts
-       $vecName(-5) You can also use  numeric  expressions  as  indices.   The
-       result  of  the expression must be an integer value.  set n 21 set vec-
-       Name($n+3) 50.2 The following special non-numeric  indices  are  avail-
-       able:  min,  max, end, and ++end.  puts "min = $vecName($min)" set vec-
-       Name(end) -1.2 The indices min and max will return the minimum and max-
-       imum values of the vector.  The index end returns the value of the last
-       component in the vector.  The index ++end is used to append  new  value
-       onto  the vector.  It automatically extends the vector by one component
-       and sets its value.  # Append an new component  to  the  end  set  vec-
-       Name(++end)  3.2 A range of indices can be indicated by a colon (:).  #
-       Set the first six components to 1.0 set vecName(0:5) 1.0 If no index is
-       supplied the first or last component is assumed.  # Print the values of
-       all the components puts $vecName(:)

-       <B>blt::vector</B> <B>create</B> <I>vecName</I>?(<I>size</I>)?... ?<I>switches</I>?
-              The <B>create</B> operation creates a new vector <I>vecName</I>.  Both  a  Tcl
-              command  and  array variable <I>vecName</I> are also created.  The name
-                     then  no  variable  will be mapped.  You can always map a
-                     variable back to the vector using the  vector's  <B>variable</B>
-                     operation.
-
-              <B>-command</B> <I>cmdName</I>
-                     Maps  a  Tcl  command  to  the  vector. The vector can be
-                     accessed using <I>cmdName</I> and one  of  the  vector  instance
-                     operations.   A  Tcl  command by that name cannot already
-                     exist.  If <I>cmdName</I> is the empty string, no  command  map-
-                     ping will be made.
-
-              <B>-watchunset</B> <I>boolean</I>
-                     Indicates  that  the  vector  should automatically delete
-                     itself if the variable  associated  with  the  vector  is
-                     unset.  By default, the vector will not be deleted.  This
-                     is different from  previous  releases.   Set  <I>boolean</I>  to
-                     "true" to get the old behavior.
-
-       <B>blt::vector</B> <B>destroy</B> <I>vecName</I> ?<I>vecName...</I>?
-              Deletes  one  or  more  vectors.  Both the Tcl command and array
-              variable are removed also.
-
-       <B>blt::vector</B> <B>expr</B> <I>expression</I>
-              All binary operators take vectors  as  operands  (remember  that
-              numbers are treated as one-component vectors).  The exact action
-              of binary operators depends upon the length of the second  oper-
-              and.   If  the  second operand has only one component, then each
-              element of the first vector operand is computed by  that  value.
-              For  example,  the  expression "x * 2" multiples all elements of
-              the vector x by 2.  If the second operand has more than one com-
-              ponent,  both  operands  must  be the same length.  Each pair of
-              corresponding elements are computed.  So "x + y"  adds  the  the
-              first components of x and y together, the second, and so on.
-
-              The  valid  operators  are  listed  below, grouped in decreasing
-              order of precedence:
-
-              <B>-</B>  <B>!</B>                Unary minus  and  logical  NOT.   The  unary
-                                  minus  flips  the  sign of each component in
-                                  the  vector.   The  logical   not   operator
-                                  returns  a vector of whose values are 0.0 or
-                                  1.0.  For each  non-zero  component  1.0  is
-                                  returned, 0.0 otherwise.
-
-              <B>^</B>                   Exponentiation.
-
-              <B>*</B>  <B>/</B>  <B>%</B>             Multiply, divide, remainder.
-
-              <B>+</B>  <B>-</B>                Add and subtract.
-
-              <B>&lt;&lt;</B>  <B>&gt;&gt;</B>              Left and right shift.  Circularly shifts the
-                                  values of the vector (not implemented  yet).
-
-              <B>&amp;&amp;</B>                  Logical AND.  Produces a 1  result  if  both
-                                  operands are non-zero, 0 otherwise.
-
-              <B>||</B>                  Logical OR.  Produces a 0 result if both op-
-                                  erands are zero, 1 otherwise.
-
-              <I>x</I><B>?</B><I>y</I><B>:</B><I>z</I>               If-then-else, as  in  C.   (Not  implemented
-                                  yet).
-
-              See  the  C  manual  for more details on the results produced by
-              each operator.  All of the binary operators group  left-to-right
-              within the same precedence level.
-
-              Several  mathematical functions are supported for vectors.  Each
-              of the following functions invokes the math library function  of
-              the  same name; see the manual entries for the library functions
-              for details on what they do.  The operation is  applied  to  all
-              elements     of    the    vector    returning    the    results.
-              <B>acos</B>    <B>cos</B>     <B>hypot</B>   <B>sinh</B>        <B>asin</B>    <B>cosh</B>    <B>log</B>     <B>sqrt</B>
-              <B>atan</B>    <B>exp</B>     <B>log10</B>   <B>tan</B> <B>ceil</B>    <B>floor</B>   <B>sin</B>     <B>tanh</B>
-
-              Additional functions are:
-
-              <B>abs</B>       Returns the absolute value of each component.
-
-              <B>random</B>    Returns a vector of non-negative values uniformly dis-
-                        tributed between [0.0, 1.0) using <I>drand48</I>.   The  seed
-                        comes from the internal clock of the machine or may be
-                        set manual with the srandom function.
-
-              <B>round</B>     Rounds each component of the vector.
-
-              <B>srandom</B>   Initializes the random number generator using <I>srand48</I>.
-                        The high order 32-bits are set using the integral por-
-                        tion of the first vector component. All  other  compo-
-                        nents  are  ignored.  The low order 16-bits are set to
-                        an arbitrary value.
-
-              The following functions return a single value.
-
-              <B>adev</B>      Returns the average deviation (defined as the  sum  of
-                        the  absolute values of the differences between compo-
-                        nent and the mean, divided by the length of  the  vec-
-                        tor).
-
-              <B>kurtosis</B>  Returns  the  degree  of peakedness (fourth moment) of
-                        the vector.
-
-              <B>length</B>    Returns the number of components in the vector.
-
-              <B>max</B>       Returns the vector's maximum value.
-
-
-              <B>skew</B>      Returns  the skewness (or third moment) of the vector.
-                        This characterizes the degree of asymmetry of the vec-
-                        tor about the mean.
-
-              <B>sum</B>       Returns the sum of the components.
-
-              <B>var</B>       Returns  the  variance  of  the vector. The sum of the
-                        squared differences between  each  component  and  the
-                        mean  is computed.  The variance is the sum divided by
-                        the length of the vector minus 1.
-
-              The last set returns a vector of the same length  as  the  argu-
-              ment.
-
-              <B>norm</B>      Scales  the  values  of the vector to lie in the range

-<H2>INSTANCE OPERATIONS</H2><PRE>
-       You  can  also use the vector's Tcl command to query or modify it.  The
-       general form is <I>vecName</I> <I>operation</I>  ?<I>arg</I>?...   Both  <I>operation</I>  and  its
-       arguments  determine the exact behavior of the command.  The operations
-       available for vectors are listed below.
-
-       <I>vecName</I> <B>append</B> <I>item</I> ?<I>item</I>?...
-              Appends the component values from <I>item</I> to <I>vecName</I>.  <I>Item</I> can  be
-              either the name of a vector or a list of numeric values.
-
-       <I>vecName</I> <B>binread</B> <I>channel</I> ?<I>length</I>? ?<I>switches</I>?
-              Reads  binary  values  from  a  Tcl  channel.  Values are either
-              appended to the end of the vector or placed  at  a  given  index
-              (using  the  <B>-at</B>  option), overwriting existing values.  Data is
-              read until EOF is found on the channel or a specified number  of
-              values  <I>length</I>  are  read (note that this is not necessarily the
-              same as the number of bytes). The following  switches  are  sup-
-              ported:
-
-              <B>-swap</B>  Swap  bytes  and  words.   The default endian is the host
-                     machine.
-
-              <B>-at</B> <I>index</I>
-                     New values will start at vector index <I>index</I>.   This  will
-                     overwrite any current values.
-
-              <B>-format</B> <I>format</I>
-                     Specifies  the  format of the data.  <I>Format</I> can be one of
-                     the following: "i1", "i2", "i4", "i8", "u1,  "u2",  "u4",
-
-              This is useful when the vector is large.
-
-       <I>vecName</I> <B>delete</B> <I>index</I> ?<I>index</I>?...
-              Deletes the <I>index</I>th component from the vector <I>vecName</I>.  <I>Index</I> is
-              the  index  of  the  element to be deleted.  This is the same as
-              unsetting the array variable element <I>index</I>.  The vector is  com-
-              pacted after all the indices have been deleted.
-
-       <I>vecName</I> <B>dup</B> <I>destName</I>
-              Copies  <I>vecName</I>  to <I>destName</I>. <I>DestName</I> is the name of a destina-
-              tion vector.  If a vector <I>destName</I> already exists, it  is  over-
-              written  with the components of <I>vecName</I>.  Otherwise a new vector
-              is created.
-
-       <I>vecName</I> <B>expr</B> <I>expression</I>
-              Computes the expression and resets  the  values  of  the  vector
-              accordingly.    Both  scalar  and  vector  math  operations  are
-              allowed.  All values in expressions are either real  numbers  or
-              names of vectors.  All numbers are treated as one component vec-
-              tors.
-
-       <I>vecName</I> <B>length</B> ?<I>newSize</I>?
-              Queries or resets the number of components in <I>vecName</I>.   <I>NewSize</I>
-              is  a  number specifying the new size of the vector.  If <I>newSize</I>
-              is smaller than the current size of <I>vecName</I>,  <I>vecName</I>  is  trun-
-              cated.   If  <I>newSize</I>  is greater, the vector is extended and the
-              new components are initialized to 0.0.  If no  <I>newSize</I>  argument
-              is present, the current length of the vector is returned.
-
-       <I>vecName</I> <B>merge</B> <I>srcName</I> ?<I>srcName</I>?...
-              Merges  the  named  vectors into a single vector.  The resulting
-              vector is formed by merging the components of each source vector
-              one index at a time.
-
-       <I>vecName</I> <B>notify</B> <I>keyword</I>
-              Controls  how vector clients are notified of changes to the vec-
-              tor.  The exact behavior is determined by <I>keyword</I>.
-
-              always Indicates that clients are  to  be  notified  immediately
-                     whenever the vector is updated.
-
-              never  Indicates that no clients are to be notified.
-

-                     Indicates  that  clients  are  to be notified at the next
-                     idle point whenever the vector is updated.
-
-              now    If any client notifications is  currently  pending,  they
-                     are notified immediately.
-
-              cancel Cancels  pending  notifications of clients using the vec-
-                     tor.
-
-              <I>density</I> number of new components, whose values are  evenly  dis-
-              tributed between the original components values.  This is useful
-              for generating abscissas to be interpolated along a spline.
-
-       <I>vecName</I> <B>range</B> <I>firstIndex</I> ?<I>lastIndex</I>?...
-              Returns a list of numeric values representing the vector  compo-
-              nents  between  two  indices.  Both <I>firstIndex</I> and <I>lastIndex</I> are
-              indices representing the range of components to be returned.  If
-              <I>lastIndex</I>  is less than <I>firstIndex</I>, the components are listed in
-              reverse order.
-
-       <I>vecName</I> <B>search</B> <I>value</I> ?<I>value</I>?
-              Searches for a value or range of values among the components  of
-              <I>vecName</I>.   If  one <I>value</I> argument is given, a list of indices of
-              the components which equal <I>value</I> is returned.  If a second <I>value</I>
-              is  also  provided, then the indices of all components which lie
-              within the range of the two values are returned.  If  no  compo-
-              nents are found, then "" is returned.
-
-       <I>vecName</I> <B>set</B> <I>item</I>
-              Resets  the components of the vector to <I>item</I>. <I>Item</I> can be either
-              a list of numeric expressions or another vector.
-
-       <I>vecName</I> <B>seq</B> <I>start</I> ?<I>finish</I>? ?<I>step</I>?
-              Generates a sequence of values starting with  the  value  <I>start</I>.
-              <I>Finish</I>  indicates  the  terminating  value of the sequence.  The
-              vector is automatically resized to contain  just  the  sequence.
-              If three arguments are present, <I>step</I> designates the interval.
-
-              With  only two arguments (no <I>finish</I> argument), the sequence will
-              continue until the vector is filled.   With  one  argument,  the
-              interval defaults to 1.0.
-
-       <I>vecName</I> <B>sort</B> ?<B>-reverse</B>? ?<I>argName</I>?...
-              Sorts  the  vector <I>vecName</I> in increasing order.  If the <B>-reverse</B>
-              flag is present, the vector is sorted in decreasing  order.   If
-              other  arguments <I>argName</I> are present, they are the names of vec-
-              tors which will be rearranged in the  same  manner  as  <I>vecName</I>.
-              Each  vector  must be the same length as <I>vecName</I>.  You could use
-              this to sort the x vector of a graph, while still retaining  the
-              same x,y coordinate pairs in a y vector.
-
-       <I>vecName</I> <B>variable</B> <I>varName</I>
-              Maps  a  Tcl  variable to the vector, creating another means for
-              accessing the vector.  The variable <I>varName</I> can't already exist.
-              This overrides any current variable mapping the vector may have.

-                   Calling <B>Blt_ResetVector</B> will trigger the vector to dispatch
-                   notifications  to its clients. <I>DataArr</I> is the array of dou-

-                   of values stored in it). <I>FreeProc</I> indicates how the storage
-                   for the vector component array (<I>dataArr</I>) was allocated.  It
-                   is used to determine how to reallocate memory when the vec-

-                   free the memory allocated for the vector array. If <I>freeProc</I>
-                   is  TCL_VOLATILE,  it indicates that <I>dataArr</I> must be copied
-                   and saved.  If <I>freeProc</I> is TCL_DYNAMIC, it  indicates  that
-                   <I>dataArr</I>  was dynamically allocated and that Tcl should free
-                   <I>dataArr</I> if necessary.  Static indicates that nothing should

-                   to 0.0.  Calling <B>Blt_ResetVector</B> will trigger the vector to

-
-
-         If  your  application  needs to be notified when a vector changes, it
-         can allocate a unique <I>client</I> <I>identifier</I> for itself.  Using this iden-
-         tifier,  you  can  then  register a call-back to be made whenever the
-         vector is updated or destroyed.  By default, the call-backs are  made
-         at the next idle point.  This can be changed to occur at the time the
-         vector is modified.  An application can allocate more than one  iden-
-         tifier  for any vector.  When the client application is done with the
-         vector, it should free the identifier.
-
-         The call-back routine must of the following type.

-<H2>INCOMPATIBILITIES</H2><PRE>
-       In previous versions, if the array variable isn't global (i.e. local to
-       a Tcl procedure), the vector is automatically destroyed when the proce-
-       dure returns.  proc doit {} {
-           # Temporary vector x

-           set <B>x(9)</B> 2.0
-             ...  }
-
-       This has changed.  Variables are not automatically destroyed when their
-       variable  is  unset.   You  can restore the old behavior by setting the

-.SH DESCRIPTION
-The \fBvector\fR command creates an array of floating point
-values.  The vector's components can be manipulated in three ways:
-through a Tcl array variable, a Tcl command, or the C API.
-.SH INTRODUCTION
-A vector is an ordered set of real numbers.  The components of a
-vector are indexed by integers.
-.PP
-Vectors are common data structures for many applications.  For
-example, a graph may use two vectors to represent the X-Y
-coordinates of the data plotted.  The graph will automatically
-be redrawn when the vectors are updated or changed. By using vectors, 
-you can separate
-data analysis from the graph widget.  This makes it easier, for
-example, to add data transformations, such as splines.  It's possible
-to plot the same data to in multiple graphs, where each graph presents
-a different view or scale of the data.
-.PP
-You could try to use Tcl's associative arrays as vectors.  Tcl arrays
-are easy to use.  You can access individual elements randomly by
-specifying the index, or the set the entire array by providing a list
-of index and value pairs for each element.  The disadvantages of 
-associative arrays as vectors lie in the fact they are implemented as
-hash tables.
-.TP 2
-\(bu 
-There's no implied ordering to the associative arrays.  If you used
-vectors for plotting, you would want to insure the second component
-comes after the first, an so on.  This isn't possible since arrays
-are actually hash tables.  For example, you can't get a range of
-values between two indices.  Nor can you sort an array.
-.TP 2
-\(bu
-Arrays consume lots of memory when the number of elements becomes
-large (tens of thousands).  This is because each element's index and
-value are stored as strings in the hash table.
-.TP 2
-\(bu 
-The C programming interface is unwieldy.  Normally with vectors, you
-would like to view the Tcl array as you do a C array, as an array of
-floats or doubles.  But with hash tables, you must convert both the
-index and value to and from decimal strings, just to access
-an element in the array.  This makes it cumbersome to perform operations on
-the array as a whole.
-.PP
-The \fBvector\fR command tries to overcome these disadvantages while
-still retaining the ease of use of Tcl arrays.  The \fBvector\fR
-command creates both a new Tcl command and associate array which are
-linked to the vector components.  You can randomly access vector
-components though the elements of array.  Not have all indices are
-generated for the array, so printing the array (using the \fBparray\fR
-procedure) does not print out all the component values.  You can use
-the Tcl command to access the array as a whole.  You can copy, append,
-or sort vector using its command.  If you need greater performance, or
-customized behavior, you can write your own C code to manage vectors.
-.SH EXAMPLE
-You create vectors using the \fBvector\fR command and its \fBcreate\fR
-operation.
-.CS
-# Create a new vector. 
-blt::vector create y(50)
-.CE
-This creates a new vector named \f(CWy\fR.  It has fifty components, by
-default, initialized to \f(CW0.0\fR.  In addition, both a Tcl command
-and array variable, both named \f(CWy\fR, are created.  You can use
-either the command or variable to query or modify components of the
-vector.
-.CS
-# Set the first value. 
-set y(0) 9.25
-puts "y has [y length] components"
-.CE
-The array \f(CWy\fR can be used to read or set individual components of
-the vector.  Vector components are indexed from zero.  The array index
-must be a number less than the number of components.  For example,
-it's an error if you try to set the 51st element of \f(CWy\fR.
-.CS
-# This is an error. The vector only has 50 components.
-set y(50) 0.02
-.CE
-You can also specify a range of indices using a colon (:) to separate
-the first and last indices of the range.
-.CS
-# Set the first six components of y 
-set y(0:5) 25.2
-.CE
-If you don't include an index, then it will default to the first
-and/or last component of the vector.
-.CS
-# Print out all the components of y 
-puts "y = $y(:)"
-.CE
-There are special non-numeric indices.  The index \f(CWend\fR, specifies
-the last component of the vector.  It's an error to use this index if
-the vector is empty (length is zero).  The index \f(CW++end\fR can be
-used to extend the vector by one component and initialize it to a specific 
-value.  You can't read from the array using this index, though.
-.CS
-# Extend the vector by one component.
-set y(++end) 0.02
-.CE
-The other special indices are \f(CWmin\fR and \f(CWmax\fR.  They return the
-current smallest and largest components of the vector.  
-.CS
-# Print the bounds of the vector
-puts "min=$y(min) max=$y(max)"
-.CE
-To delete components from a vector, simply unset the corresponding
-array element. In the following example, the first component of
-\f(CWy\fR is deleted.  All the remaining components of \f(CWy\fR will be
-moved down by one index as the length of the vector is reduced by
-one.
-.CS
-# Delete the first component
-unset y(0)
-puts "new first element is $y(0)"
-.CE
-The vector's Tcl command can also be used to query or set the vector.
-.CS
-# Create and set the components of a new vector
-blt::vector create x
-x set { 0.02 0.04 0.06 0.08 0.10 0.12 0.14 0.16 0.18 0.20 }
-.CE
-Here we've created a vector \f(CWx\fR without a initial length specification.
-In this case, the length is zero.  The \fBset\fR operation resets the vector,
-extending it and setting values for each new component.  
-.PP
-There are several operations for vectors.  The \fBrange\fR operation
-lists the components of a vector between two indices.
-.CS
-# List the components 
-puts "x = [x range 0 end]"
-.CE
-You can search for a particular value using the \fBsearch\fR
-operation.  It returns a list of indices of the components with the
-same value.  If no component has the same value, it returns \f(CW""\fR.
-.CS
-# Find the index of the biggest component
-set indices [x search $x(max)]
-.CE
-Other operations copy, append, or sort vectors.  You can append
-vectors or new values onto an existing vector with the \fBappend\fR
-operation.
-.CS
-# Append assorted vectors and values to x
-x append x2 x3 { 2.3 4.5 } x4
-.CE
-The \fBsort\fR operation sorts the vector.  If any additional vectors
-are specified, they are rearranged in the same order as the vector.
-For example, you could use it to sort data points represented by x and
-y vectors.
-.CS
-# Sort the data points
-x sort y
-.CE
-The vector \f(CWx\fR is sorted while the components of \f(CWy\fR are 
-rearranged so that the original x,y coordinate pairs are retained.
-.PP
-The \fBexpr\fR operation lets you perform arithmetic on vectors.  
-The result is stored in the vector.
-.CS
-# Add the two vectors and a scalar
-x expr { x + y }
-x expr { x * 2 }
-.CE
-When a vector is modified, resized, or deleted, it may trigger
-call-backs to notify the clients of the vector.  For example, when a
-vector used in the \fBgraph\fR widget is updated, the vector
-automatically notifies the widget that it has changed.  The graph can
-then redrawn itself at the next idle point.  By default, the
-notification occurs when Tk is next idle.  This way you can modify the
-vector many times without incurring the penalty of the graph redrawing
-itself for each change.  You can change this behavior using the
-\fBnotify\fR operation.
-.CS
-# Make vector x notify after every change
-x notify always
-	...
-# Never notify
-x notify never
-	...
-# Force notification now
-x notify now
-.CE
-To delete a vector, use the \fBvector delete\fR command.  
-Both the vector and its corresponding Tcl command are destroyed.
-.CS
-# Remove vector x
-blt::vector destroy x
-.CE
-.SH SYNTAX
-Vectors are created using the \fBvector create\fR operation.  
-Th \fBcreate\fR operation can be invoked in one of three forms:
-.TP
-\fBblt::vector create \fIvecName\fR
-This creates a new vector \fIvecName\fR which initially has no components.
-.TP
-\fBblt::vector create \fIvecName\fR(\fIsize\fR)
-This second form creates a new vector which will contain \fIsize\fR
-number of components.  The components will be indexed starting from
-zero (0). The default value for the components is \f(CW0.0\fR.
-.TP
-\fBblt::vector create \fIvecName\fR(\fIfirst\fR:\fIlast\fR)
-The last form creates a new vector of indexed \fIfirst\fR through
-\fIlast\fR.  \fIFirst\fR and \fIlast\fR can be any integer value
-so long as \fIfirst\fR is less than \fIlast\fR.
-.PP
-Vector names must start with a letter and consist of letters, digits,
-or underscores.  
-.CS
-# Error: must start with letter
-blt::vector create 1abc
-.CE
-You can automatically generate vector names using the
-"\f(CW#auto\fR" vector name.  The \fBcreate\fR operation will generate a 
-unique vector name.
-.CS
-set vec [blt::vector create #auto]
-puts "$vec has [$vec length] components"
-.CE
-.SS VECTOR INDICES
-Vectors are indexed by integers.  You can access the individual vector
-components via its array variable or Tcl command.  The string
-representing the index can be an integer, a numeric expression, a
-range, or a special keyword.
-.PP
-The index must lie within the current range of the vector, otherwise
-an an error message is returned.  Normally the indices of a vector
-are start from 0.  But you can use the \fBoffset\fR operation to
-change a vector's indices on-the-fly.
-.CS
-puts $vecName(0)
-vecName offset -5
-puts $vecName(-5)
-.CE
-You can also use numeric expressions as indices.  The result
-of the expression must be an integer value.  
-.CS
-set n 21
-set vecName($n+3) 50.2
-.CE
-The following special non-numeric indices are available: \f(CWmin\fR, \f(CWmax\fR, \f(CWend\fR, and
-\f(CW++end\fR.  
-.CS
-puts "min = $vecName($min)"
-set vecName(end) -1.2
-.CE
-The indices \f(CWmin\fR and \f(CWmax\fR will return the minimum and maximum
-values of the vector.  The index \f(CWend\fR returns the value of the 
-last component in the vector.  The index \f(CW++end\fR is used to append
-new value onto the vector.  It automatically extends the vector by
-one component and sets its value.
-.CS
-# Append an new component to the end
-set vecName(++end) 3.2
-.CE
-A range of indices can be indicated by a colon (:).  
-.CS
-# Set the first six components to 1.0
-set vecName(0:5) 1.0
-.CE
-If no index is supplied the first or last component is assumed.
-.CS
-# Print the values of all the components
-puts $vecName(:)
-.CE
-.SH VECTOR OPERATIONS
-.TP
-\fBblt::vector create \fIvecName\fR?(\fIsize\fR)?... \fR?\fIswitches\fR? 
-The \fBcreate\fR operation creates a new vector \fIvecName\fR.  Both a
-Tcl command and array variable \fIvecName\fR are also created.  The
-name \fIvecName\fR must be unique, so another Tcl command or array
-variable can not already exist in that scope.  You can access the
-components of the vector using its variable.  If you change a value in
-the array, or unset an array element, the vector is updated to reflect
-the changes.  When the variable \fIvecName\fR is unset, the vector and
-its Tcl command are also destroyed.
-.sp
-The vector has optional switches that affect how the vector is created. They
-are as follows:
-.RS
-.TP
-\fB\-variable \fIvarName\fR
-Specifies the name of a Tcl variable to be mapped to the vector. If
-the variable already exists, it is first deleted, then recreated. 
-If \fIvarName\fR is the empty string, then no variable will be mapped.
-You can always map a variable back to the vector using the vector's 
-\fBvariable\fR operation.
-.TP
-\fB\-command \fIcmdName\fR
-Maps a Tcl command to the vector. The vector can be accessed using 
-\fIcmdName\fR and one of the vector instance operations.  
-A Tcl command by that name cannot already exist.
-If \fIcmdName\fR is the empty string, no command mapping
-will be made.
-.TP
-\fB\-watchunset \fIboolean\fR
-Indicates that the vector should automatically delete itself if
-the variable associated with the vector is unset.  By default,
-the vector will not be deleted.  This is different from previous
-releases.  Set \fIboolean\fR to "true" to get the old behavior.
-.RE
-.TP
-\fBblt::vector destroy \fIvecName\fR \fR?\fIvecName...\fR?
-Deletes one or more vectors.  Both the Tcl command and array variable
-are removed also.
-.TP
-\fBblt::vector expr \fIexpression\fR
-.RS
-All binary operators take vectors as operands (remember that numbers
-are treated as one-component vectors).  The exact action of binary
-operators depends upon the length of the second operand.  If the
-second operand has only one component, then each element of the first
-vector operand is computed by that value.  For example, the expression
-"x * 2" multiples all elements of the vector x by 2.  If the second
-operand has more than one component, both operands must be the same
-length.  Each pair of corresponding elements are computed.  So "x + y"
-adds the the first components of x and y together, the second, and so on.
-.sp
-The valid operators are listed below, grouped in decreasing order
-of precedence:
-.TP 20
-\fB\-\0\0!\fR

-.SH C API EXAMPLE
-The following example opens a file of binary data and stores it in an
-array of doubles. The array size is computed from the size of the
-file. If the vector "data" exists, calling \fBBlt_VectorExists\fR,
-\fBBlt_GetVector\fR is called to get the pointer to the vector.
-Otherwise the routine \fBBlt_CreateVector\fR is called to create a new
-vector and returns a pointer to it. Just like the Tcl interface, both
-a new Tcl command and array variable are created when a new vector is
-created. It doesn't make any difference what the initial size of the
-vector is since it will be reset shortly. The vector is updated when
-\fBlt_ResetVector\fR is called.  Blt_ResetVector makes the changes
-visible to the Tcl interface and other vector clients (such as a graph
-widget).

- * layoutGraph --
- *
- *	Calculate the layout of the graph.  Based upon the data, axis limits,
- *	X and Y titles, and title height, determine the cavity left which is
- *	the plotting surface.  The first step get the data and axis limits for
- *	calculating the space needed for the top, bottom, left, and right
- *	margins.
- *
- * 	1) The LEFT margin is the area from the left border to the Y axis 
- *	   (not including ticks). It composes the border width, the width an 
- *	   optional Y axis label and its padding, and the tick numeric labels. 
- *	   The Y axis label is rotated 90 degrees so that the width is the 
- *	   font height.
- *
- * 	2) The RIGHT margin is the area from the end of the graph
- *	   to the right window border. It composes the border width,
- *	   some padding, the font height (this may be dubious. It
- *	   appears to provide a more even border), the max of the
- *	   legend width and 1/2 max X tick number. This last part is
- *	   so that the last tick label is not clipped.

- *
- * 4) The BOTTOM margin is area from the bottom window border to the
- *    X axis (not including ticks). It composes the border width, the height
- *    an optional X axis label and its padding, the height of the font
- *    of the tick labels.

- *
- * BinreadOp --
- *
- *	Reads binary values from a TCL channel. Values are either appended to
- *	the end of the vector or placed at a given index (using the "-at"
- *	option), overwriting existing values.  Data is read until EOF is found
- *	on the channel or a specified number of values are read.  (note that
- *	this is not necessarily the same as the number of bytes).
- *
- *	The following flags are supported:
- *		-swap		Swap bytes
- *		-at index	Start writing data at the index.
- *		-format fmt	Specifies the format of the data.
- *
- *	This binary reader was created and graciously donated by Harald Kirsch
- *	(kir@iitb.fhg.de).  Anything that's wrong is due to my (gah) munging
- *	of the code.
- *
- * Results:
- *	Returns a standard TCL result. The interpreter result will contain the
- *	number of values (not the number of bytes) read.
- *
- * Caveats:
- *	Channel reads must end on an element boundary.

-
-	* tcl.m4: My previous commit (2012-04-03) broke the ActiveTcl
-	build for AMD64, because of the quotes in "C:/<path>/AMD64/cl.exe".
-	It turns out that the AC_TRY_COMPILE macro cannot handle that.
-
-2012-07-22  Stuart Cassoff  <stwo@users.sourceforge.net>

-
-	* tcl.m4: [FREQ #3058486] TEA_LOAD_CONFIG doesn't set all BUILD_ vars
-	Slightly related: defining BUILD_$1 on all platforms - not only win -
-	allows the -fvisibility feature to be used in extensions as well, at
-	least if you compile against tcl >= 8.5.
-
-2010-08-26  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: ensure safe quoting for autoheader usage
-
-2010-08-19  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: add TEA_ADD_CLEANFILES macro to make adding cleanfiles
-	easier, and add *.exp to CLEANFILES Windows default.
-	(TEA_MAKE_LIB): Enhanced to check for MSVC that requires manifests
-	and auto-embed it into proj DLL via MAKE_SHARED_LIB.  Also define
-	VC_MANIFEST_EMBED_DLL and VC_MANIFEST_EMBED_EXE that do the same
-	magic in case it is needed for extended TEA projects.
-
-2010-08-16  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	*** Bump to TEA_VERSION 3.9 ***
-	If upgrading from TEA_VERSION 3.8, copy over tcl.m4, change
-	TEA_INIT to use 3.9 and reconfigure (ac-2.59+).
-	BUILD_${PACKAGE_NAME} will be auto-defined on Windows for
-	correct setting of TCL_STORAGE_CLASS.
-	TEA_LOAD_CONFIG users should remove the SHLIB_LD_LIBS setting done
-	in configure.in (LIBS will be automagically populated by
-	TEA_LOAD_CONFIG).
-	TEA_EXPORT_CONFIG has been added for ${pkg}Config.sh creators
-	SHLIB_LD_FLAGS was deprecated a while ago, remove it if it is
-	still in your Makefile.in.
-
-	* tcl.m4: add /usr/lib64 to set of auto-search dirs. [Bug 1230554]
-	Auto-define BUILD_$PACKAGE_NAME so users don't need to.  This
-	needs to correspond with $pkg.h define magic for TCL_STORAGE_CLASS.
-	Auto-define CLEANFILES.  Users can expand it.
-	(SHLIB_LD_LIBS): define to '${LIBS}' default and change it only if
-	necessary.  Platforms not using this may simply not work or have
-	very funky linkers.
-	(TEA_LOAD_CONFIG): When loading config for another extension,
-	auto-add stub libraries found with TEA_ADD_LIBS.  Eases
-	configure.in for modules like itk and img::*.
-	(TEA_EXPORT_CONFIG): Add standardized function for exporting a
-	${pkg}Config.sh.  See use by img::* and itcl.
-
-2010-08-12  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	*** Bump to TEA_VERSION 3.8 ***
-	If upgrading from TEA_VERSION 3.7, copy over tcl.m4, change
-	TEA_INIT to use 3.8 and reconfigure (ac-2.59+).
-	No other changes should be necessary.
-
-	* tcl.m4: remove more vestigial bits from removed platforms.
-	Add back SCO_SV-3.2*.
-	Remove use of DL_LIBS and DL_OBJS and related baggage - these are
-	only needed by the core to support 'load'.
-	Allow for macosx in TEA_ADD_SOURCES.
-	Correct check for found_xincludes=no in TEA_PATH_UNIX_X.
-
-2010-08-11  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: remove the following old platform configurations:
-	UNIX_SV*|UnixWare-5*, SunOS-4.*, SINIX*5.4*, SCO_SV-3.2*<readded>,
-	OSF1-1.*, NEXTSTEP-*, NetBSD-1.*|FreeBSD-[[1-2]].*, MP-RAS-*,
-	IRIX-5.*, HP-UX-*.08.*|HP-UX-*.09.*|HP-UX-*.10.*, dgux*,
-	BSD/OS-2.1*|BSD/OS-3*
-	(AIX): drop AIX-pre4 support and use of ldAix, use -bexpall/-brtl
-
-2010-07-05  Jan Nijtmans  <nijtmans@users.sf.net>
-
-	* tcl.m4: [Patch #1055668] removal of exported internals from
-	tclInt.h (EXTERN macro)
-
-2010-04-14  Jan Nijtmans  <nijtmans@users.sf.net>
-
-	* tcl.m4    - Backport a lot of quoting fixes from tcl8.6/unix/tcl.m4
-	            - Fix determination of CYGPATH for CYGWIN
-	  With those fixes, itcl and tdbc compile fine with CYGWIN
-
-2010-04-06  Jan Nijtmans  <nijtmans@users.sf.net>
-
-	* install-sh         [Bug 2982540] configure and install* script files
-	                     should always have LF
-
-2010-02-19  Stuart Cassoff  <stwo@users.sourceforge.net>
-

-	* tcl.m4 (Darwin): check for 64-bit TkAqua.
-
-2009-03-26  Jan Nijtmans  <nijtmans@users.sf.net>
-
-	* tclconfig/tcl.m4: Adapt LDFLAGS and LD_SEARCH_FLAGS
-	together with SHLIB_LD definition to unbreak building on HPUX.
-
-2009-03-20  Andreas Kupries  <andreask@activestate.com>
-
-	* tclconfig/tcl.m4: Changed SHLIB_LD definition to unbreak
-	building on HPUX.
-
-2009-03-16  Joe English  <jenglish@users.sourceforge.net>
-
-	* tcl.m4(TEA_PUBLIC_TK_HEADERS): Look at ${TK_INCLUDE_SPEC}
-	(found in tkConfig.sh) when trying to guess where tk.h might be
-	[Patch 1960628].
-
-2009-03-11  Joe English  <jenglish@users.sourceforge.net>
-
-	* tcl.m4: Allow ${SHLIB_SUFFIX} to be overridden at

-
-	* tcl.m4: [Bug 2073255] Tcl_GetString(NULL) doesn't crash on HP-UX

-
-2008-11-04  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4 (TEA_PATH_TCLCONFIG, TEA_PATH_TKCONFIG): exit with error
-	when tclConfig.sh cannot be found. [Bug #1997760]

-
-2008-08-12  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4 (Darwin): link shlib with current and compatiblity version

-	*** Tagged tea-3-branch to start TEA 4 development on HEAD ***
-
-2007-09-17  Joe English  <jenglish@users.sourceforge.net>
-
-	* tcl.m4: use '${CC} -shared' instead of 'ld -Bshareable'
-	to build shared libraries on current NetBSDs [Bug 1749251].
-
-2007-09-15  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4: 	replace all direct references to compiler by ${CC} to

-	problems.
-
-2007-03-07  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4 (Darwin): s/CFLAGS/CPPFLAGS/ in -mmacosx-version-min check.
-
-2007-02-15  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: correct private header check to search in generic subdir
-
-2007-02-09  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	*** Bump to TEA_VERSION 3.6 ***
-
-	* tcl.m4: correct -d to -f

-2007-02-04  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4: add caching to -pipe check.
-
-2007-01-25  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4: integrate CPPFLAGS into CFLAGS as late as possible and
-	move (rather than duplicate) -isysroot flags from CFLAGS to CPPFLAGS to
-	avoid errors about multiple -isysroot flags from some older gcc builds.
-
-2006-01-19  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4: ensure CPPFLAGS env var is used when set. [Bug 1586861]
-	(Darwin): add -isysroot and -mmacosx-version-min flags to CPPFLAGS when
-	present in CFLAGS to avoid discrepancies between what headers configure
-	sees during preprocessing tests and compiling tests.
-
-2006-12-19  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4 (Darwin): --enable-64bit: verify linking with 64bit -arch flag
-	succeeds before enabling 64bit build.
-
-2006-12-16  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4 (Linux): fix previous change to use makefile variable
-	LDFLAGS_DEFAULT instead of LDFLAGS in SHLIB_LD, to ensure linker
-	flags in sampleextension Makefile are picked up.
-
-2006-11-26  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4 (Linux): --enable-64bit support. [Patch 1597389], [Bug 1230558]

-	universal builds including x86_64 and for use of -mmacosx-version-min
-	instead of MACOSX_DEPLOYMENT_TARGET. For Tk extensions, remove 64-bit
-	arch flags from CFLAGS like in the Tk configure, as neither TkAqua nor
-	TkX11 can be built for 64-bit at present.

-2006-03-28  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: []-quote AC_DEFUN functions.

-
-2006-01-25  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	*** Bump to TEA version 3.5 ***
-
-	* tcl.m4: keep LD_SEARCH_FLAGS and CC_SEARCH_FLAGS synchronous
-	with core tcl.m4 meaning.
-
-2006-01-24  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4 (Darwin): use makefile variable LDFLAGS_DEFAULT instead of

-2006-01-23  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4 (Darwin): for Tk extensions, remove -arch ppc64 from CFLAGS
-	like in the Tk configure, as neither TkAqua nor TkX11 can be built for
-	64bit at present (no 64bit GUI libraries).
-
-2006-01-22  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: restore system=windows on Windows.
-	Remove error if 'ar' isn't found (it may not be on Windows).
-	Do not add -lxnet or define _XOPEN_SOURCE on HP-UX by default.
-	Ensure the C|LDFLAGS_DEFAULT gets the fully sub'd value at
-	configure time.
-
-2006-01-10  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4: add caching, use AC_CACHE_CHECK instead of AC_CACHE_VAL
-	where possible, consistent message quoting, sync relevant
-	tcl/unix/tcl.m4 HEAD changes and gratuitous formatting differences
-	(notably sunc removal of support for for ancient BSD's, IRIX 4,
-	RISCos and Ultrix by kennykb), Darwin improvements to
-	TEA_LOAD_*CONFIG to make linking work against Tcl/Tk frameworks
-	installed in arbitrary location, change TEA_PROG_* search order
-	(look in *_BIN_DIR parents before *_PREFIX).
-
-2006-01-05  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: add dkf's system config refactor
-
-2006-01-04  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: remove extraneous ' that causes bash 3.1 to choke
-
-2005-12-19  Joe English  <jenglish@users.sourceforge.net>
-
-	* tcl.m4 (TEA_PATH_TCLCONFIG &c): Look for tclConfig.sh &c
-	in ${libdir}, where they are installed by default [Patch #1377407].
-
-2005-12-05  Don Porter  <dgp@users.sf.net>
-
-	* tcl.m4 (TEA_PUBLIC_*_HEADERS):	Better support for finding
-	header files for uninstalled Tcl and Tk.
-
-2005-12-02  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: correctly bump TEA_VERSION var to 3.4
-
-2005-12-01  Daniel Steffen  <das@users.sourceforge.net>
-
-	* unix/tcl.m4 (Darwin): fixed error when MACOSX_DEPLOYMENT_TARGET unset
-
-2005-11-29  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4:  *** Bump to TEA version 3.4 ***
-	Add Windows x64 build support.
-	Remove TEA_PATH_NOSPACE and handle the problem with ""s where
-	necessary - the macro relied on TCLSH_PROG which didn't work for
-	cross-compiles.
-
-2005-11-27  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4 (Darwin): add 64bit support, add CFLAGS to SHLIB_LD to
-	support passing -isysroot in env(CFLAGS) to configure (flag can't
-	be present twice, so can't be in both CFLAGS and LDFLAGS during
-	configure), don't use -prebind when deploying on 10.4.
-	(TEA_ENABLE_LANGINFO, TEA_TIME_HANDLER): add/fix caching.
-
-2005-10-30  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4: fixed two tests for TEA_WINDOWINGSYSTEM = "aqua" that
-	should have been for `uname -s` = "Darwin" instead; added some
-	missing quoting.
-	(TEA_PROG_TCLSH, TEA_PROG_WISH): fix incorrect assumption that
-	install location of tclConfig.sh/tkConfig.sh allows to determine
-	the tclsh/wish install dir via ../bin. Indeed tcl/tk can be
-	configured with arbitrary --libdir and --bindir (independent of
-	prefix) and such a configuration is in fact standard with Darwin
-	framework builds. At least now also check ${TCL_PREFIX}/bin
-	resp. ${TK_PREFIX}/bin for presence of tclsh resp. wish (if tcl/tk
-	have been configured with arbitrary --bindir, this will still not
-	find them, for a general solution *Config.sh would need to contain
-	the values of bindir/libdir/includedir passed to configure).
-
-2005-10-07  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: Fix Solaris 5.10 check and Solaris AMD64 64-bit builds.
-
-2005-10-04  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4 (TEA_PRIVATE_TCL_HEADERS): add / to finish sed macro
-	(TEA_ENABLE_THREADS): don't check for pthread_attr_setstacksize func
-
-2005-09-13  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: *** Update to TEA version 3.3 ***
-	define TEA_WINDOWINGSYSTEM in TEA_LOAD_TKCONFIG.
-	Make --enable-threads the default (users can --disable-threads).
-	Improve AIX ${CC}_r fix to better check existing ${CC} value.
-	Do the appropriate evals to not require the *TOP_DIR_NATIVE vars
-	be set for extensions that use private headers.
-	Make aqua check for Xlib compat headers the same as win32.
-
-2005-07-26  Mo DeJong  <mdejong@users.sourceforge.net>
-
-	* tcl.m4 (TEA_PROG_TCLSH, TEA_BUILD_TCLSH,
-	TEA_PROG_WISH, TEA_BUILD_WISH): Remove
-	TEA_BUILD_TCLSH and TEA_BUILD_WISH because
-	of complaints that it broke the build when
-	only an installed version of Tcl was available
-	at extension build time. The TEA_PROG_TCLSH and
-	TEA_PROG_WISH macros will no longer search the
-	path at all. The build tclsh or installed
-	tclsh shell will now be found by TEA_PROG_TCLSH.
-
-2005-07-24  Mo DeJong  <mdejong@users.sourceforge.net>
-
-	* tcl.m4 (TEA_PROG_TCLSH, TEA_BUILD_TCLSH,
-	TEA_PROG_WISH, TEA_BUILD_WISH):
-	Split confused search for tclsh on PATH and
-	build and install locations into two macros.
-	TEA_PROG_TCLSH and TEA_PROG_WISH search the
-	system PATH for an installed tclsh or wish.
-	The TEA_BUILD_TCLSH and TEA_BUILD_WISH
-	macros determine the name of tclsh or
-	wish in the Tcl or Tk build directory even
-	if tclsh or wish has not yet been built.
-	[Tcl bug 1160114]
-	[Tcl patch 1244153]
-
-2005-06-23  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4 (TEA_PRIVATE_TK_HEADERS): add ${TK_SRC_DIR}/macosx to
-	TK_INCLUDES when building against TkAqua.
-
-	* tcl.m4 (TEA_PATH_X): fixed missing comma in AC_DEFINE
-
-	* tcl.m4: changes to better support framework builds of Tcl and Tk out
-	of the box: search framework install locations for *Config.sh, and if in
-	presence of a framework build, use the framework's Headers and
-	PrivateHeaders directories for public and private includes. [FR 947735]
-
-2005-06-18  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4 (Darwin): add -headerpad_max_install_names to LDFLAGS to
-	ensure we can always relocate binaries with install_name_tool.
-
-2005-06-04  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4 (TEA_PATH_X): for TEA_WINDOWINGSYSTEM == aqua, check if xlib
-	compat headers are available in tkheaders location, otherwise add xlib
-	sourcedir to TK_XINCLUDES.
-
-2005-04-25  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4: added AC_DEFINE* descriptions (from core tcl.m4) to allow
-	use with autoheader.
-	(Darwin): added configure checks for recently added linker flags
-	-single_module and -search_paths_first to allow building with older
-	tools (and on Mac OS X 10.1), use -single_module in SHLIB_LD.
-	(TEA_MISSING_POSIX_HEADERS): added caching of dirent.h check.
-	(TEA_BUGGY_STRTOD): added caching (sync with core tcl.m4).
-
-2005-03-24  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4 (TEA_TCL_64BIT_FLAGS): use Tcl header defaults for wide
-	int type only on Windows when __int64 is detected as valid.
-
-2005-03-24  Don Porter  <dgp@users.sf.net>
-
-	* README.txt:	Update reference to "SC_* macros" to "TEA_* macros".
-	* tcl.m4:	Incorporated recent improvements in SC_PATH_TCLCONFIG
-	and SC_PATH_TKCONFIG into TEA_PATH_TCLCONFIG and TEA_PATH_TKCONFIG.
-	Corrected search path in TEA_PATH_CONFIG and added
-	AC_SUBST($1_BIN_DIR) to TEA_LOAD_CONFIG so that packages that load
-	the configuration of another package can know where they loaded
-	it from.
-
-2005-03-18  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4 (TEA_CONFIG_CFLAGS): correct 2005-03-17 change to have
-	variant LD_SEARCH_FLAGS for gcc and cc builds.
-
-	* tcl.m4 (TEA_PROG_TCLSH, TEA_PROG_WISH): correct x-compile check.
-
-2005-03-17  Jeff Hobbs  <jeffh@ActiveState.com>

-2005-02-08  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4 (TEA_ADD_LIBS): don't touch lib args starting with -.
-	(TEA_CONFIG_CFLAGS): only define _DLL for CE in shared build.
-	(TEA_MAKE_LIB): set RANLIB* to : on Windows (it's not needed).
-
-2005-02-01  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: redo of 2005-01-27 changes to correctly handle paths
-	with spaces.  Win/CE and Win/64 builds now require a prebuilt
-	tclsh to handle conversion to short pathnames.  This is done in
-	the new TEA_PATH_NOSPACE macro.  For Win/CE|64, make CC just the
-	compiler and move the necessary includes to CFLAGS.
-	(TEA_CONFIG_CFLAGS): Add Solaris 64-bit gcc build support.
-	(TEA_PROG_TCLSH, TEA_PROG_WISH): Allow TCLSH_PROG and WISH_PROG to
-	be set in the env and prevent resetting.
-	(TEA_ADD_LIBS): On Windows using GCC (mingw), convert foo.lib
-	args to -lfoo, for use with mingw.
-		*** POTENTIAL INCOMPATABILITY ***
-	(TEA_CONFIG_CFLAGS): Fix AIX gcc builds to work out-of-box.
-	Bumped TEA to 3.2.

-2005-01-27  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: remove cygpath calls to support msys.
-	Update base CE build assumption to "420,ARMV4,ARM,Pocket PC 2003".
-	Make STLIB_LD use $LINKBIN -lib.
-
-2005-01-25  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4 (Darwin): fixed bug with static build linking to dynamic
-	library in /usr/lib etc instead of linking to static library earlier
-	in search path. [Tcl Bug 956908]
-	Removed obsolete references to Rhapsody.
-
-2004-12-29  Jeff Hobbs  <jeffh@ActiveState.com>

-	* tcl.m4: Updates for VC7 compatibility, fixing CFLAGS and LDFLAGS
-	options, using better default -O levels. [Bug 1092952, 1091967]
-
-2004-12-29  Joe English  <jenglish@users.sourceforge.net>
-
-	* tcl.m4: Do not use ${DBGX} suffix when building
-	shared libraries [patch #1081595, TIP #34]
-
-2004-09-07  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4 (TEA_CONFIG_CFLAGS): support eVC4 Win/CE builds
-
-2004-08-10  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4 (TEA_INIT, TEA_PREFIX): update handling of exec_prefix to
-	work around subdir configures since autoconf only propagates the
-	prefix (not exec_prefix).
-
-2004-07-23  Daniel Steffen  <das@users.sourceforge.net>
-
-	* tcl.m4 (TEA_CONFIG_CFLAGS): Darwin section: brought inline with
-	Tcl 8.5 HEAD config, removed core specific & obsolete settings.
-
-2004-07-22  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4 (TEA_PATH_X): check in TK_DEFS for MAC_OSX_TK to see if
-	we are compiling on Aqua.  Add TEA_WINDOWINGSYSTEM var that
-	reflects 'tk windowingsystem' value.
-
-2004-07-16  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4 (TEA_ENABLE_THREADS): force a threaded build when
-	building against a threaded core.
-	(CFLAGS_WARNING): Remove -Wconversion for gcc builds
-	(TEA_CONFIG_CFLAGS): Reorder configure.in for better 64-bit build
-	configuration, replacing EXTRA_CFLAGS with CFLAGS.  [Bug #874058]
-	Update to latest Tcl 8.5 head config settings.
-	Call this TEA version 3.1.
-
-2004-04-29  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4 (TEA_TCL_64BIT_FLAGS): replace AC_TRY_RUN test with
-	AC_TRY_COMPILE for the long vs. long long check. (kenny)
-
-2004-04-26  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4 (TEA_TCL_64BIT_FLAGS): update against core tcl.m4 to
-	define TCL_WIDE_INT_IS_LONG if 'using long'.
-
-2004-03-19  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: correct Windows builds getting LDFLAGS info in MAKE_LIB
-
-2004-02-11  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: correct TCL_INCLUDES for private headers on Windows - it
-	doesn't need the eval.
-
-2004-02-10  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: don't require TK_INCLUDES and TCL_INCLUDES to have the
-	DIR_NATIVE vars defined when using private headers on unix.
-	Allow $... to TEA_ADD_SOURCES for constructs like
-	TEA_ADD_SOURCES([\$(WIN_OBJECTS)]), that allow the developer to
-	place more in the Makefile.in.
-	tkUnixPort.h checks for HAVE_LIMITS_H, so do both HAVE and
-	CHECK on limits.h
-
-2003-12-10  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* Makefile.in:      added TEA_ADD_LIBS, TEA_ADD_INCLUDES and
-	* configure:        TEA_ADD_CFLAGS to configurable parameters with
-	* configure.in:     PKG_* equivs in the Makefile.  This allows the
-	* tclconfig/tcl.m4: user to worry less about actual magic VAR names.
-	Corrected Makefile.in to note that TEA_ADD_TCL_SOURCES requires
-	exact file names.
-
-2003-12-09  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: updated OpenBSD support based on [Patch #775246] (cassoff)
-
-2003-12-05  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* configure:
-	* configure.in:
-	* Makefile.in (VPATH): readd $(srcdir) to front of VPATH as the
-	first part of VPATH can get chopped off.
-	Change .c.$(OBJEXT) rule to .c.@OBJEXT@ to support more makes.
-	* tclconfig/tcl.m4: add TEA_ADD_STUB_SOURCES to support libstub
-	generation and TEA_ADD_TCL_SOURCES to replace RUNTIME_SOURCES as
-	the way the user specifies library files.
-
-2003-12-03  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* configure:           Update of TEA spec to (hopefully) simplify
-	* configure.in:        some aspects of TEA by making use of more
-	* Makefile.in:         AC 2.5x features.  Use PACKAGE_NAME (instead
-	* generic/tclsample.c: of PACKAGE) and PACKAGE_VERSION (instead of
-	* tclconfig/tcl.m4:    VERSION) arguments to AC_INIT as the TEA
-	package name and version.
-	Provide a version argument to TEA_INIT - starting with 3.0.
-	Drop all use of interior shell substs that older makefiles didn't
-	like.  Use PKG_* naming convention instead.
-	Move specification of source files and public headers into
-	configure.in with TEA_ADD_SOURCES and TEA_ADD_HEADERS.  These will
-	be munged during ./configure into the right obj file names (no
-	$(SOURCES:.c=.obj) needed).
-	There is almost nothing that should be touched in Makefile.in now
-	for the developer.  May want to add a TEA_ADD_TCL_SOURCES for the
-	RUNTIME_SOURCES that remains.
-	Use SHLID_LD_FLAGS (instead of SHLID_LDFLAGS) as Tcl does.
-	Only specify the user requested LDFLAGS/CFLAGS in the Makefile,
-	don't mention the _OPTIMIZE/_DEBUG variants.
-
-2003-10-15  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: create a TEA_SETUP_COMPILER_CC the precedes the
-	TEA_SETUP_COMPILER macro.  They are split so the check for CC
-	occurs before any use of CC.  Also add AC_PROG_CPP to the compiler
-	checks.
-
-2003-10-06  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: Updated for autoconf 2.5x prereq.
-	Where TCL_WIDE_INT_TYPE would be __int64, defer to the code checks
-	in tcl.h, which also handles TCL_LL_MODIFIER* properly.
-
-2003-04-22  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: correct default setting of ARCH for WinCE builds.
-	Correct \ escaping for CE sed macros.
-
-2003-04-10  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: replace $(syscal) construct with older `syscall` for
-	systems where sh != bash.
-
-2003-04-09  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4 (TEA_WITH_CELIB): add --enable-wince and --with-celib
-	options for Windows/CE compilation support.  Requires the
-	Microsoft eMbedded SDK and Keuchel's celib emulation layer.
-
-2003-02-18  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4 (TEA_ENABLE_THREADS): Make sure -lpthread gets passed on
-	the link line when checking for the pthread_attr_setstacksize
-	symbol. (dejong)
-
-	* tcl.m4 (TEA_SETUP_COMPILER): added default calls to
-	TEA_TCL_EARLY_FLAGS, TEA_TCL_64BIT_FLAGS,
-	TEA_MISSING_POSIX_HEADERS and TEA_BUGGY_STRTOD.
-
-2003-02-14  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: correct HP-UX ia64 --enable-64bit build flags
-
-2003-01-29  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: check $prefix/lib as well as $exec_prefix/lib when
-	looking for tcl|tkConfig.sh, as this check is done before we would
-	set exec_prefix when the user does not define it.
-
-2003-01-21  Mo DeJong  <mdejong@users.sourceforge.net>
-
-	* tcl.m4 (TEA_CONFIG_CFLAGS): Fix build support
-	for mingw, the previous implementation would
-	use VC++ when compiling with mingw gcc. Don't
-	pass -fPIC since gcc always compiles pic code
-	under win32. Change some hard coded cases
-	of gcc to ${CC}.
-
-2002-10-15  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: move the CFLAGS definition from TEA_ENABLE_SHARED to
-	TEA_MAKE_LIB because setting too early confuses other AC_* macros.
-	Correct the HP-11 SHLIB_LD_LIBS setting.
-
-	* tcl.m4: add the CFLAGS definition into TEA_ENABLE_SHARED and
-	make it pick up the env CFLAGS at configure time.
-
-2002-10-09  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: add --enable-symbols=mem option to enable TCL_MEM_DEBUG.
-	Improved AIX 64-bit build support, allow it on AIX-4 as well.
-	Enable 64-bit HP-11 compilation with gcc.
-	Enable 64-bit IRIX64-6 cc build support.
-	Correct FreeBSD thread library linkage.
-	Add OSF1 static build support.
-	Improve SunOS-5 shared build SHLIB_LD macro.
-
-2002-07-20  Zoran Vasiljevic  <zoran@archiware.com>
-
-	* tcl.m4: Added MINGW32 to list of systems checked for Windows build.
-	Also, fixes some indentation issues with "--with-XXX" options.
-
-2002-04-23  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4 (TEA_ENABLE_THREADS): added USE_THREAD_ALLOC define to
-	use new threaded allocatory by default on Unix for Tcl 8.4.
-	(TEA_CONFIG_CFLAGS): corrected LD_SEARCH_FLAGS for FreeBSD-3+.
-
-2002-04-22  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4 (TEA_SETUP_COMPILER): removed call to AC_CYGWIN so that
-	we can use autoconf 2.5x as well as 2.13.  This prevents us from
-	being able to warn against the use of cygwin gcc at configure
-	time, but allows autoconf 2.5x, which is what is shipped with most
-	newer systems.
-
-2002-04-11  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: Enabled COFF as well as CV style debug info with
-	--enable-symbols to allow Dr. Watson users to see function info.
-	More info on debugging levels can be obtained at:
-	http://msdn.microsoft.com/library/en-us/dnvc60/html/gendepdebug.asp
-
-2002-04-03  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: change all SC_* macros to TEA_*.  The SC_ was for
-	Scriptics, which is no more.  TEA represents a better, independent
-	prefix that won't need changing.
-	Added preliminary mingw gcc support. [Patch #538772]
-	Added TEA_PREFIX macro that handles defaulting the prefix and
-	exec_prefix vars to those used by Tcl if none were specified.
-	Added TEA_SETUP_COMPILER macro that encompasses the AC_PROG_CC
-	check and several other basic AC_PROG checks needed for making
-	executables.  This greatly simplifies user's configure.in files.
-	Collapsed AIX-5 defines into AIX-* with extra checks for doing the
-	ELF stuff on AIX-5-ia64.
-	Updated TEA_ENABLE_THREADS to take an optional arg to allow
-	switching it on by default (for Thread) and add sanity checking to
-	warn the user if configuring threads incompatibly.
-
-2002-03-29  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: made sure that SHLIB_LDFLAGS was set to LDFLAGS_DEFAULT.
-	Removed --enable-64bit support for AIX-4 because it wasn't correct.
-	Added -MT or -MD Windows linker switches to properly support
-	symbols-enabled builds.
-
-2002-03-28  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: called AC_MSG_ERROR when SC_TEA_INIT wasn't called first
-	instead of calling it as that inlines it each time in shell code.
-	Changed Windows CFLAGS_OPTIMIZE to use -O2 instead of -Oti.
-	Noted TCL_LIB_VERSIONS_OK=nodots for Windows builds.
-	A few changes to support itcl (and perhaps others):
-	Added support for making your own stub libraries to SC_MAKE_LIB.
-	New SC_PATH_CONFIG and SC_LOAD_CONFIG that take a package name arg
-	and find that ${pkg}Config.sh file.  itk uses this for itcl.
-
-2002-03-27  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: made SC_LOAD_TKCONFIG recognize when working with a Tk
-	build dir setup.
-	Added EXTRA_CFLAGS and SHLIB_LD_LIBS substs to SC_CONFIG_CFLAGS.
-	Added XLIBSW onto LIBS when it is defined.
-	Remove TCL_LIBS from MAKE_LIB and correctly use SHLIB_LD_LIBS
-	instead to not rely as much on tclConfig.sh cached info.
-	Add TK_BIN_DIR to paths to find wish in SC_PROG_WISH.
-	These move towards making TEA much more independent of *Config.sh.
-
-2002-03-19  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: corrected forgotten (UN)SHARED_LIB_SUFFIX and
-	SHLIB_SUFFIX defines for Win.
-	(SC_PATH_X): made this only do the check on unix platforms.
-
-2002-03-12  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* README.txt: updated to reflect fewer files
-
-2002-03-06  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* config.guess (removed):
-	* config.sub (removed): removed unnecessary files
-
-	* installFile.tcl (removed):
-	* mkinstalldirs (removed): these aren't really necessary for
-	making TEA work
-
-	* tcl.m4 (SC_PUBLIC_TCL_HEADERS, SC_PUBLIC_TK_HEADERS): don't
-	check /usr(/local)/include for includes on Windows when not using
-	gcc
-
-2002-03-05  Jeff Hobbs  <jeffh@ActiveState.com>
-
-	* tcl.m4: added warnings on Windows, removed RELPATH define and
-	added TCL_LIBS to MAKE_LIB macro.
-
-	This import represents 2.0.0, or a new start at attempting to
-	make TEA much easier for C extension developers.
-
-	**** moved from tclpro project to core tcl project, ****
-	**** renamed to 'tclconfig'                         ****
-
-2001-03-15    Karl Lehenbauer <karl@procplace.com>
-
-	* installFile.tcl: Added updating of the modification time of
-	  the target file whether we overwrote it or decided that it
-	  hadn't changed.  This was necessary for us to be able to
-	  determine whether or not a module install touched the file.
-
-2001-03-08    Karl Lehenbauer <karl@procplace.com>
-
-	* installFile.tcl: Added support for converting new-style (1.1+)
-	  Cygnus drive paths to Tcl-style.
-
-2001-01-15    <brent.welch@interwoven.com>
-
-	* tcl.m4: Added FreeBSD clause.
-
-2001-01-03    <brent.welch@interwoven.com>
-
-	* tcl.m4: Fixed typo in SC_LIB_SPEC where it is checking
-	for exec-prefix.
-
-2000-12-01    <brent.welch@interwoven.com>
-
-	* tcl.m4: Concatenated most of the Ajuba acsite.m4 file
-	so we don't need to modify the autoconf installation.
-	* config.guess:
-	* config.sub:
-	* installFile.tcl:
-	Added files from the itcl config subdirectory,
-	which should go away.
-
-2000-7-29    <welch@ajubasolutions.com>
-
-	* Fixed the use of TCL_SRC_DIR and TK_SRC_DIR within
-	TCL_PRIVATE_INCLUDES and TK_PRIVATE_INCLUDES to match their recent
-	change from $(srcdir) to $(srcdir)/..

-#                       as tclsh.

-#                       that tell the run-time dynamic linker where to look
-#                       for shared libraries such as libtcl.so.  Depends on
-#                       the variable LIB_RUNTIME_DIR in the Makefile. Could
-#                       be the same as CC_SEARCH_FLAGS if ${CC} is used to link.
-#       CC_SEARCH_FLAGS-Flags to pass to ${CC}, such as "-Wl,-rpath,/usr/local/tcl/lib",
-#                       that tell the run-time dynamic linker where to look
-#                       for shared libraries such as libtcl.so.  Depends on
-#                       the variable LIB_RUNTIME_DIR in the Makefile.
-#       SHLIB_CFLAGS -  Flags to pass to cc when compiling the components
-#                       of a shared library (may request position-independent
-#                       code, among other things).
-#       SHLIB_LD -      Base command to use for combining object files
-#                       into a shared library.
-#       SHLIB_LD_LIBS - Dependent libraries for the linker to scan when
-#                       creating shared libraries.  This symbol typically
-#                       goes at the end of the "ld" commands that build
-#                       shared libraries. The value of the symbol defaults to
-#                       "${LIBS}" if all of the dependent libraries should
-#                       be specified when creating a shared library.  If
-#                       dependent libraries should not be specified (as on
-#                       SunOS 4.x, where they cause the link to fail, or in
-#                       general if Tcl and Tk aren't themselves shared
-#                       libraries), then this symbol has an empty string
-#                       as its value.
-#       SHLIB_SUFFIX -  Suffix to use for the names of dynamically loadable
-#                       extensions.  An empty string means we don't know how
-#                       to use shared libraries on this platform.
-#       LIB_SUFFIX -    Specifies everything that comes after the "libfoo"
-#                       in a static or shared library name, using the $PACKAGE_VERSION variable
-#                       to put the version in the right place.  This is used
-#                       by platforms that need non-standard library names.
-#                       Examples:  ${PACKAGE_VERSION}.so.1.1 on NetBSD, since it needs
-#                       to have a version after the .so, and ${PACKAGE_VERSION}.a
-#                       on AIX, since a shared library needs to have
-#                       a .a extension whereas shared objects for loadable
-#                       extensions have a .so extension.  Defaults to
-#                       ${PACKAGE_VERSION}${SHLIB_SUFFIX}.
-#	CFLAGS_DEBUG -
-#			Flags used when running the compiler in debug mode
-#	CFLAGS_OPTIMIZE -
-#			Flags used when running the compiler in optimize mode
-#	CFLAGS -	Additional CFLAGS added as necessary (usually 64-bit)
