Examples of XYErrorRenderer

org.jfree.chart.renderer.xy.XYErrorRenderer
A line and shape renderer that can also display x and/or y-error values. This renderer expects an {@link IntervalXYDataset}, otherwise it reverts to the behaviour of the super class. The example shown here is generated by the XYErrorRendererDemo1.java program included in the JFreeChart demo collection:
