Usage

From source file:sturesy.voting.gui.VotingEvaluationPanelUI.java

private JFreeChart createChart(final CategoryDataset dataset, String questiontext, Color background,
        boolean showAnswers, List<Integer> correctAnswers, boolean showPercent) {
    String valueAxisLabel = Localize.getString(showPercent ? "label.votes.percent" : "label.votes.absolute");

    final JFreeChart chart = ChartFactory.createBarChart(questiontext, Localize.getString("label.answers"),
            valueAxisLabel, dataset, PlotOrientation.VERTICAL, false, true, false);

    chart.setBackgroundPaint(background);

    final CategoryPlot plot = chart.getCategoryPlot();
    plot.setNoDataMessage("NO DATA!");

    final CategoryItemRenderer renderer = new AnswersBarRenderer(showAnswers, correctAnswers);

    renderer.setBaseItemLabelsVisible(true);
    renderer.setBaseItemLabelFont(renderer.getBaseItemLabelFont().deriveFont(16.0f));

    final ItemLabelPosition p = new ItemLabelPosition(ItemLabelAnchor.CENTER, TextAnchor.CENTER,
            TextAnchor.CENTER, 45.0);/*from  w w w.ja v a2  s . c o m*/

    renderer.setBasePositiveItemLabelPosition(p);

    plot.setRenderer(renderer);

    // change the margin at the top of the range axis...
    final ValueAxis rangeAxis = plot.getRangeAxis();
    rangeAxis.setStandardTickUnits(NumberAxis.createIntegerTickUnits());
    rangeAxis.setLowerMargin(0.15);
    rangeAxis.setUpperMargin(0.15);
    double upperrange = rangeAxis.getRange().getUpperBound();

    if (showPercent) {
        renderer.setBaseItemLabelGenerator(new AppendPercentRenderer());
        rangeAxis.setRange(new Range(0, upperrange > 100 ? 100 : upperrange), false, false);
    } else {
