public class CategoryTableXYDataset
extends AbstractIntervalXYDataset
implements TableXYDataset, IntervalXYDataset, DomainInfo

An implementation variant of the `TableXYDataset` where every series shares the same x-values (required for generating stacked area charts). This implementation uses a `DefaultKeyedValues2D` Object as backend implementation and is hence more "category oriented" than the `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 `IntervalXYDataset` interface, but this implementation is provisional.
