Class XYErrorRenderer

Implemented Interfaces:
Cloneable, LegendItemSource, PublicCloneable, Serializable, XYItemRenderer
public class XYErrorRenderer
extends XYLineAndShapeRenderer
A line and shape renderer that can also display x and/or y-error values. This renderer expects an IntervalXYDataset, otherwise it reverts to the behaviour of the super class.
Since:
1.0.3
