Interface CategoryItemLabelGenerator

All Known Implementing Classes:
IntervalCategoryItemLabelGenerator, StandardCategoryItemLabelGenerator
public interface CategoryItemLabelGenerator
A category item label generator is an object that can be assigned to a CategoryItemRenderer and that assumes responsibility for creating text items to be used as labels for the items in a CategoryPlot.

To assist with cloning charts, classes that implement this interface should also implement the PublicCloneable interface.
