Examples of org.jfree.data.xy.CategoryTableXYDataset

org.jfree.data.xy.CategoryTableXYDataset
An implementation variant of the {@link TableXYDataset} where every seriesshares the same x-values (required for generating stacked area charts). This implementation uses a {@link DefaultKeyedValues2D} Object as backendimplementation and is hence more "category oriented" than the {@link DefaultTableXYDataset} implementation.
This implementation provides no means to remove data items yet. This is due to the lack of such facility in the DefaultKeyedValues2D class.
This class also implements the {@link IntervalXYDataset} interface, but thisimplementation is provisional.
