Examples of org.jfree.chart.labels.CategoryItemLabelGenerator

org.jfree.chart.labels.CategoryItemLabelGenerator
A category item label generator is an object that can be assigned to a {@link org.jfree.chart.renderer.category.CategoryItemRenderer} and thatassumes responsibility for creating text items to be used as labels for the items in a {@link org.jfree.chart.plot.CategoryPlot}.
To assist with cloning charts, classes that implement this interface should also implement the {@link org.jfree.util.PublicCloneable} interface.
