- All Implemented Interfaces:
Serializable,Cloneable,LegendItemSource,CategoryItemRenderer,PublicCloneable
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:
