Examples of org.jfree.chart.JFreeChart.draw()

org.jfree.chart.JFreeChart.draw()
Draws the chart on a Java 2D graphics device (such as the screen or a printer).
This method is the focus of the entire JFreeChart library. @param g2 the graphics device. @param area the area within which the chart should be drawn.




        BufferedImage img = new BufferedImage
            (width, height, BufferedImage.TYPE_INT_RGB);
        Graphics2D g2 = img.createGraphics();
        chart.draw(g2, new Rectangle2D.Double(0, 0, width, height));
        g2.dispose();


        int quality = (parameters.containsKey("EXPORT") ? 85 : 100);
        JpegEncoder jpegEncoder = new JpegEncoder(img, quality, outStream);
        jpegEncoder.Compress();
