Interface XYBarPainter

All Known Implementing Classes:

GradientXYBarPainter, StandardXYBarPainter

public interface XYBarPainter

The interface for plugin painter for the XYBarRenderer class. When developing a class that implements this interface, bear in mind the following:

• the equals(Object) method should be overridden;
• instances of the class should be immutable OR implement the PublicCloneable interface, so that a renderer using the painter can be cloned reliably;
• the class should be Serializable, otherwise chart serialization will not be supported.

Method Summary

Modifier and Type	Method	Description
void	paintBar(Graphics2D g2, XYBarRenderer renderer, int row, int column, RectangularShape bar, RectangleEdge base)	Paints a single bar on behalf of a renderer.
void	paintBarShadow(Graphics2D g2, XYBarRenderer renderer, int row, int column, RectangularShape bar, RectangleEdge base, boolean pegShadow)	Paints the shadow for a single bar on behalf of a renderer.
