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.

        double[][] starts = new double[][] {starts_S1, starts_S2};
        double[][] ends = new double[][] {ends_S1, ends_S2};
        DefaultIntervalCategoryDataset d1 = new DefaultIntervalCategoryDataset(
                new Comparable[] {"Series 1", "Series 2"},
                new Comparable[] {"Category 1", "Category 2", "Category 3"},
                DataUtilities.createNumberArray2D(starts),
                DataUtilities.createNumberArray2D(ends));
        DefaultIntervalCategoryDataset d2 = null;

        // check that the clone doesn't share the same underlying arrays.
        d1.setStartValue(0, "Category 1", new Double(0.99));
