public class MinMaxCategoryRenderer extends AbstractCategoryItemRenderer
Renderer for drawing min max plot. This renderer draws all the series under the same category in the same x position using objectIcon and a line from the maximum value to the minimum value. For use with the CategoryPlot class. The example shown here is generated by the MinMaxCategoryPlotDemo1.java program included in the JFreeChart Demo Collection:
