public class MyMinimalPieChartExample {

    private static final String KEY1 = "Datum 1";
    public static final String KEY2 = "Datum 2";

    public static void main(String[] args) {
        DefaultPieDataset dataset = new DefaultPieDataset();
        dataset.setValue(KEY1, 99);
        dataset.setValue(KEY2, 77);

        JFreeChart someChart = ChartFactory.createPieChart(
            "Header", dataset, true, true, false);
        PiePlot plot = (PiePlot) someChart.getPlot();
        plot.setSectionPaint(KEY1, Color.green);
        plot.setSectionPaint(KEY2, Color.red);
        plot.setExplodePercent(KEY1, 0.10);
        plot.setSimpleLabels(true);

        PieSectionLabelGenerator gen = new StandardPieSectionLabelGenerator(
            "{0}: {1} ({2})", new DecimalFormat("0"), new DecimalFormat("0%"));
        plot.setLabelGenerator(gen);

        JFrame f = new JFrame("Test");
