public DefaultIntervalCategoryDataset(Comparable[] seriesKeys, Comparable[] categoryKeys, Number[][] starts, 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:
seriesKeys
- the series keys.categoryKeys
- the categories.starts
- the start values data, indexed as data[series][category].ends
- the end values data, indexed as data[series][category].
public DefaultIntervalCategoryDataset(Number[][] starts, Number[][] ends)

starts
- the start values data.ends
- the end values data.
public DefaultIntervalCategoryDataset(String[] seriesNames, Number[][] starts, 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].
