createXYBarChart, IntervalXYDataset and StackedXYBarRenderer

[peetzer]

I use the 'XYBarDataset' to adjust the width of the bar, the (xy) dataset contains timeperiods..
All works fine using the 'XYBarRenderer' but when two series overlap, one gets on top of the other. So that is why I want to use the 'StackedXYBarRenderer' but I get an java.lang.ClassCastException org.jfree.data.xy.XYBarDataset in StackedXYBarRenderer.findRangeBounds

Please advise,

Regards Peter
