Interface BarPainter

All Known Implementing Classes:

GradientBarPainter, StandardBarPainter

public interface BarPainter

The interface for plugin painter for the BarRenderer 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.

Since:

1.0.11
