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

org.jfree.chart.JFreeChart.createBufferedImage()
Creates and returns a buffered image into which the chart has been drawn. @param width the width. @param height the height. @return A buffered image.

            chart.getXYPlot().setDomainAxis(0, new DateAxis());
            chart.getXYPlot().setDomainAxis(1, new DateAxis());
            chart.getXYPlot().setInsets(new RectangleInsets(-15, 0, 0, 10));


            response.setHeader("Content-type", "image/png");
            response.getOutputStream().write(ChartUtilities.encodeAsPNG(chart.createBufferedImage(width, height)));
        }


        return null;
