Interface CategoryToolTipGenerator

public interface CategoryToolTipGenerator

A category tool tip generator is an object that can be assigned to a CategoryItemRenderer and that assumes responsibility for creating text items to be used as tooltips for the items in a CategoryPlot.

To assist with cloning charts, classes that implement this interface should also implement the org.jfree.util.PublicCloneable interface (in JCommon).

Method Summary
