Class Overview

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.

Public Constructors

public DefaultIntervalXYDataset ()

Creates a new DefaultIntervalXYDataset instance, initially containing no data.

Public Methods

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).

public Object clone ()

Returns a clone of this dataset.

Returns
  • A clone.
Throws
CloneNotSupportedException if the dataset contains a series with a key that cannot be cloned.

public boolean equals (Object obj)

Tests this DefaultIntervalXYDataset instance for equality with an arbitrary object. This method returns true if and only if:

  • obj is not null;
  • obj is an instance of DefaultIntervalXYDataset;
  • both datasets have the same number of series, each containing exactly the same values.

Parameters
obj the object (null permitted).
Returns
  • A boolean.

public Number getEndX (int series, int item)

Returns the ending x-value for an item within a series.

Parameters
series the series index (in the range 0 to getSeriesCount() - 1).
item the item index (in the range 0 to getItemCount(series)).
Returns
  • The ending x-value.
Throws
ArrayIndexOutOfBoundsException if series is not within the specified range.
ArrayIndexOutOfBoundsException if item is not within the specified range.
See Also

public double getEndXValue (int series, int item)
