Examples of org.jfree.chart.renderer.xy.XYBarRenderer.findDomainBounds()

org.jfree.chart.renderer.xy.XYBarRenderer.findDomainBounds()
Returns the lower and upper bounds (range) of the x-values in the specified dataset. Since this renderer uses the x-interval in the dataset, this is taken into account for the range. @param dataset the dataset (null permitted). @return The range (null if the dataset isnull or empty).

        XYIntervalSeriesCollection dataset = new XYIntervalSeriesCollection();
        dataset.addSeries(s1);
        dataset.addSeries(s2);
        
        XYBarRenderer renderer = new XYBarRenderer();
        Range r = renderer.findDomainBounds(dataset);
        assertEquals(0.5, r.getLowerBound(), EPSILON);
        assertEquals(4.1, r.getUpperBound(), EPSILON);
        
        renderer.setSeriesVisible(1, Boolean.FALSE);
        r = renderer.findDomainBounds(dataset);
