From source file:de.berlios.statcvs.xml.report.ActivityProgressionChart.java

private JFreeChart createContourPlot() {
    Grouper grouper = settings.getGrouper(new ModuleGrouper(settings.getModules(content)));

    ContourDataset data = createDataset(grouper);
    if (data == null) {
        return null;
    }// w  ww . ja  v  a  2  s.  c o  m

    ValueAxis xAxis = new DateAxis(I18n.tr("Date"));

    SymbolicAxis yAxis = new SymbolicAxis(grouper.getName(), (String[]) groupNames.toArray(new String[0]));
    yAxis.setInverted(true);
    yAxis.setLowerMargin(0.0);
    yAxis.setUpperMargin(0.0);

    ColorBar zAxis = new ColorBar(I18n.tr("Commit Activity (%)"));
    zAxis.getAxis();

    ContourPlot plot = new ContourPlot(data, xAxis, yAxis, zAxis);
    //plot.setRenderAsPoints(true);
    // don't use plot units for ratios when x axis is date
    plot.setDataAreaRatio(0.0);
    plot.setColorBarLocation(RectangleEdge.BOTTOM);

    return new JFreeChart(settings.getProjectName(), null, plot, false);
