Interface IntervalXYDataset

All Superinterfaces:

Dataset, SeriesDataset, XYDataset

All Known Implementing Classes:

AbstractIntervalXYDataset, CategoryTableXYDataset, CombinedDataset, DefaultIntervalXYDataset, DefaultTableXYDataset, DynamicTimeSeriesCollection, HistogramDataset, SimpleHistogramDataset, SubSeriesDataset, TimePeriodValuesCollection, TimeSeriesCollection, TimeTableXYDataset, XIntervalSeriesCollection, XYBarDataset, XYIntervalSeriesCollection, XYSeriesCollection, XYTaskDataset, YIntervalSeriesCollection

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 interface is used to support (among other things) bar plots against numerical axes.
