    BarRenderer renderer = (BarRenderer) chart.getCategoryPlot().getRenderer();     
    CategoryItemLabelGenerator generator = new StandardCategoryItemLabelGenerator();

    /* Remove Bar Border*/
    renderer.setDrawBarOutline(false);

    //Spaces between bars
    renderer.setItemMargin(0.05);
    renderer.setSeriesPaint(0, Color.red);

    CategoryPlot plot = chart.getCategoryPlot();
    plot.setRangeGridlinesVisible(false);

    CategoryAxis axis = plot.getDomainAxis();
