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.

      PlotOrientation po = PlotOrientation.VERTICAL;
      JFreeChart chart = ChartFactory.createStackedBarChart(title, "Month", "Amount", dataset, po, true, true, true);


      CategoryPlot plot = (CategoryPlot) chart.getPlot();
      plot.setForegroundAlpha(0.5f);
      BufferedImage bi = chart.createBufferedImage(chartWidth, chartHeight, BufferedImage.TRANSLUCENT, null);
      byte[] bytes = EncoderUtil.encode(bi, ImageFormat.PNG, true);


      AImage chartImage = new AImage("Stacked Bar Chart", bytes);


      Image img = new Image();
