Examples of DeviationRenderer

org.jfree.chart.renderer.xy.DeviationRenderer
A specialised subclass of the {@link XYLineAndShapeRenderer} that requiresan {@link IntervalXYDataset} and represents the y-interval by shading anarea behind the y-values on the chart. The example shown here is generated by the DeviationRendererDemo1.java program included in the JFreeChart demo collection:
