Interface CategoryToolTipGenerator

All Known Implementing Classes:

BoxAndWhiskerToolTipGenerator, IntervalCategoryToolTipGenerator, StandardCategoryToolTipGenerator

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

java.lang.String

generateToolTip(CategoryDataset dataset, int row, int column) Generates the tool tip text for an item in a dataset.
