public class DefaultIntervalXYDataset

extends AbstractIntervalXYDataset

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 IntervalXYDataset interface is provided by the XYIntervalSeriesCollection class.

Since:: 1.0.3

addSeries

public void addSeries(Comparable seriesKey,
                      double[][] data)

Adds a series or if a series with the same key already exists replaces the data for that series, then sends a DatasetChangeEvent to all registered listeners.
Parameters:
seriesKey - the series key (null not permitted).
data - the data (must be an array with length 6, containing six arrays of equal length, the first containing the x-values and the second containing the y-values).
