public class DefaultIntervalCategoryDataset
extends AbstractSeriesDataset
implements IntervalCategoryDataset

A convenience class that provides a default implementation of the IntervalCategoryDataset interface.

The standard constructor accepts data in a two dimensional array where the first dimension is the series, and the second dimension is the category.

Field Summary

protected java.lang.Object[]	categories The categories.
protected java.lang.Number[][]	endData Storage for the end value data.
protected java.lang.String[]	seriesNames The series names.
protected java.lang.Number[][]	startData Storage for the start value data.

Constructor Detail

DefaultIntervalCategoryDataset

public DefaultIntervalCategoryDataset(double[][] starts,
                                      double[][] ends)

DefaultIntervalCategoryDataset

public DefaultIntervalCategoryDataset(java.lang.Number[][] starts,
                                      java.lang.Number[][] ends)

Constructs a dataset and populates it with data from the array.

The arrays are indexed as data[series][category]. Series and category names are automatically generated - you can change them using the setSeriesName(...) and setCategory(...) methods.

Parameters:

starts - The start values data.

ends - The end values data.

DefaultIntervalCategoryDataset

public DefaultIntervalCategoryDataset(java.lang.String[] seriesNames,
                                      java.lang.Number[][] starts,
                                      java.lang.Number[][] ends)

Constructs a DefaultIntervalCategoryDataset, populates it with data from the arrays, and uses the supplied names for the series.

Category names are generated automatically ("Category 1", "Category 2", etc).

Parameters:

seriesNames - The series names.

starts - The start values data, indexed as data[series][category].

ends - The end values data, indexed as data[series][category].

DefaultIntervalCategoryDataset

public DefaultIntervalCategoryDataset(java.lang.String[] seriesNames,
                                      java.lang.Object[] categories,
                                      java.lang.Number[][] starts,
                                      java.lang.Number[][] ends)

Constructs a DefaultIntervalCategoryDataset, populates it with data from the arrays, and uses the supplied names for the series and the supplied objects for the categories.

Parameters:

seriesNames - The series names.

categories - The categories.

starts - The start values data, indexed as data[series][category].

ends - The end values data, indexed as data[series][category].
