org.jfree.chart.renderer.category.GroupedStackedBarRenderer
A renderer that draws stacked bars within groups. This will probably be merged with the {@link StackedBarRenderer} class at some point. The exampleshown here is generated by the StackedBarChartDemo4.java program included in the JFreeChart Demo Collection:
