Examples of SlidingCategoryDataset

org.jfree.data.category.SlidingCategoryDataset
A {@link CategoryDataset} implementation that presents a subset of thecategories in an underlying dataset. The index of the first "visible" category can be modified, which provides a means of "sliding" through the categories in the underlying dataset. @since 1.0.10
