Interface DialFrame

public interface DialFrame extends DialLayer

A dial frame is the face plate for a dial plot - it is always drawn last. JFreeChart includes a couple of implementations of this interface (StandardDialFrame and ArcDialFrame).

Classes that implement this interface should be Serializable, otherwise chart serialization may fail.

Since: 1.0.7

Method Summary
