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.

        // a redraw should NOT trigger another change event
        BufferedImage image = new BufferedImage(200, 100,
                BufferedImage.TYPE_INT_RGB);
        Graphics2D g2 = image.createGraphics();
        this.events.clear();
        chart.draw(g2, new Rectangle2D.Double(0.0, 0.0, 200.0, 100.0));
        assertTrue(this.events.isEmpty());
