I am trying to create a StackedXYArea chart using cewolf. I get a ClassCastException in the post processer, presumably when I try to cast the XYItemRenderer to StackedXYAreaRenderer2. I am using chart type areaxy in the cewolf tags. Is this the problem? Does cewolf taglib support stacked area charts? If so, what is the chart type/renderer class that should be used?
StackedXYArea is supported - for simple charts and not for overlaid ones; try the type "stackedarea"
