Examples of org.jfree.data.xy.DefaultIntervalXYDataset

org.jfree.data.xy.DefaultIntervalXYDataset
A dataset that defines a range (interval) for both the x-values and the y-values. This implementation uses six arrays to store the x, start-x, end-x, y, start-y and end-y values.

An alternative implementation of the {@link IntervalXYDataset} interfaceis provided by the {@link XYIntervalSeriesCollection} class. @since 1.0.3
