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:

equals

public boolean equals(Object obj)

Tests this instance for equality with an arbitrary object. The icon fields are NOT included in the test, so this implementation is a little weak.
