Interface CategoryToolTipGenerator

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

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

                              int column)
Generates the tool tip text for an item in a dataset. Note: in the current dataset implementation, each row is a series, and each column contains values for a particular category.
