Examples of org.jfree.data.category.DefaultIntervalCategoryDataset

org.jfree.data.category.DefaultIntervalCategoryDataset
A convenience class that provides a default implementation of the {@link 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.
