Examples of StackedXYAreaRenderer

org.jfree.chart.renderer.xy.StackedXYAreaRenderer
A stacked area renderer for the {@link XYPlot} class.

The example shown here is generated by the StackedXYAreaRendererDemo1.java program included in the JFreeChart demo collection:

SPECIAL NOTE: This renderer does not currently handle negative data values correctly. This should get fixed at some point, but the current workaround is to use the {@link StackedXYAreaRenderer2} class instead.
