- All Superinterfaces:
- Dataset, SeriesDataset, XYDataset
- All Known Implementing Classes:
- SubSeriesDataset, TimeSeriesCollection, CombinedDataset, SimpleIntervalXYDataset
- public interface IntervalXYDataset
- extends XYDataset
An extension of the XYDataset interface that allows a range of data to be
defined for the X values, the Y values, or both the X and Y values.
This versatile interface will be used to support (among other things) bar
plots against numerical axes.
