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.

        yAxis.setFixedDimension(100.0);
        BufferedImage image = new BufferedImage(500, 300, 
                BufferedImage.TYPE_INT_RGB);
        Graphics2D g2 = image.createGraphics();
        ChartRenderingInfo info = new ChartRenderingInfo();
        chart.draw(g2, new Rectangle2D.Double(0, 0, 500, 300), info);
        g2.dispose();
        Rectangle2D rect = info.getPlotInfo().getDataArea();
        double x = rect.getMinX();
        assertEquals(100.0, x, 1.0);
