org.jfree.chart.renderer.category.BarRenderer
A {@link CategoryItemRenderer} that draws individual data items as bars.The example shown here is generated by the BarChartDemo1.java program included in the JFreeChart Demo Collection:

        rangeAxis.setStandardTickUnits(NumberAxis.createIntegerTickUnits());


        // disable bar outlines...
        BarRenderer renderer = (BarRenderer) plot.getRenderer();
        renderer.setDrawBarOutline(false);


        // set up gradient paints for series...
        GradientPaint gp0 = new GradientPaint(0.0f, 0.0f, Color.blue,
                0.0f, 0.0f, new Color(0, 0, 64));
