        final XYDataset dataset = createDataset();
        final JFreeChart chart = createChart(dataset);
       
        try {
            File f1 = new File("myline.png");
            ChartUtilities.saveChartAsPNG(f1, chart, 500, 400);
        } catch (Exception e) {
            e.printStackTrace();
        }
