Description

The AreaChart2D() function makes it possible to draw two-dimensional area charts. The 1st data series in the ChartData() function provides the x-values, the 2nd data series the y-values for the first area, the 3rd and 4th data series in ChartData() the x and y-values for the second area, etc.

As for one-dimensional area charts, symbols (appearanceConstants = symbol), shadow (appearanceConstants = shadow) and labels (appearanceConstants = label) can also be added to the areas by using the argument appearanceConstants. The options can be combined arbitrarily by using a plus sign " +". Rotating (appearanceConstants = horizontal) is not supported for two-dimensional charts as this is simply possible by switching the data series in ChartData() .

By using the 2nd argument fillAreaToAxis, it is possible to extend the fill to the x-axis and/or y-axis. The following three options are available:

  • fillAreaToAxis =​ 0: no fill to the axis (default)
  • fillAreaToAxis =​ 1: fill to the x-axis
  • fillAreaToAxis =​ 2: fill to the y-axis
