org.jfree.chart.labels
Interface CategoryItemLabelGenerator
- IntervalCategoryItemLabelGenerator, StandardCategoryItemLabelGenerator
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
org.jfree.util.PublicCloneable
interface.

public String generateColumnLabel(CategoryDataset dataset,
int column)
