- * ON INPUT--

- * 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.

- *
- * 3) The TOP margin is the area from the top window border to the top
- * of the graph. It composes the border width, twice the height of
- * the title font (if one is given) and some padding between the
- * title.
- *
- * 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.
- *
- * The plotting area is between the margins which includes the X and Y axes
- * including the ticks but not the tick numeric labels. The length of the
- * ticks and its padding is 5% of the entire plotting area. Hence the entire
- * plotting area is scaled as 105% of the width and height of the area.
- *
- * The axis labels, ticks labels, title, and legend may or may not be
- * displayed which must be taken into account.
