title: jfreechart customize piechart to show absolute values and percentages
body: <p>How can this compilable minimal code snippet example, which uses JFreeChart as plotting API, adapted in order to show  <strong>both absoulte values AND percentages</strong>?
  I couldn't extract this information neither from any code snippet on the internet nor from the JFreechart manual itself. The code snippet produces a pie chart showing only percentages. The absolute values in my case also matter, so i need to display them right under the percentages.</p>
  
  <p>Here is the code: <em>(Note it lacks the imports)</em></p>
  
  <pre><code>public class MyMinimalPieChartExample {
      public static void main(String[] args) {
      DefaultPieDataset dataset = new DefaultPieDataset();
      dataset.setValue("some data 1",99);
      dataset.setValue("some data 2", 77);
  
      //third adaption
      JFreeChart someChart = ChartFactory.createPieChart(
              "some chart header", dataset,
              true, true, false);
      PiePlot illegalLegalRestPiePlot4 = (PiePlot) someChart.getPlot();
      illegalLegalRestPiePlot4.setSectionPaint("some data 1", new Color(0, 255, 0));
      illegalLegalRestPiePlot4.setSectionPaint("some data 2",
              new Color(255, 0, 0));
      PiePlot plot4 = (PiePlot) someChart.getPlot();
      plot4.setExplodePercent("some data 1", 0.4);
      plot4.setSimpleLabels(true);
  
      PieSectionLabelGenerator generator = new StandardPieSectionLabelGenerator(
              "{0} = {2}", new DecimalFormat("0"), new DecimalFormat("0.00%"));
      plot4.setLabelGenerator(generator);
  
      try {
          ChartUtilities.saveChartAsJPEG(new File("C:/myMinimalPieChartExample.jpeg"),
                  someChart, 1200, 1000);
      } catch (Exception e) {
          System.err.println("couldn't write chart");
      }
      }
  }
  </code></pre>
