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.

        ends[0][2] = 6.0;
        ends[1][0] = 16.0;
        ends[1][1] = 15.0;
        ends[1][2] = 14.0;


        DefaultIntervalCategoryDataset d = new DefaultIntervalCategoryDataset(
                starts, ends);
        Range r = DatasetUtilities.iterateRangeBounds(d, false);
        assertEquals(4.0, r.getLowerBound(), EPSILON);
        assertEquals(16.0, r.getUpperBound(), EPSILON);
        r = DatasetUtilities.iterateRangeBounds(d, true);

            CategoryPlot plot = new CategoryPlot(dataset, 
                    new CategoryAxis("Category"), new NumberAxis("Value"), 
                    renderer);
            JFreeChart chart = new JFreeChart(plot);
