public class EnhancedStackedXYBarRenderer
extends org.jfree.chart.renderer.xy.StackedXYBarRenderer
implements EnhancedItemRenderer

Handles some additional drawing for StackedXYBarCharts. It can draw labels with the total value of all the series at each point above the bar. It also draws regular item labels since the default StackedXYBarRenderer doesn't do that yet (though that may included in a new release of jfreechart). It also allows for setting the stroke and paint of individual items in a series. This is useful for hilighting or focusing on an item.
