Spider Chart?

    Although JFreeChart includes a Spider Chart graph feature, it appears this is not yet supported in CeWolf.  Is this true?  Any chance this will be possible in the near future?

      You can register custom chart factories, here's the pattern, see CewolfChartFactory class:

      // histogram chart type
      CewfolfChartFactory.registerFactory(new CewolfChartFactory("histogram") {
              public JFreeChart getChartInstance(String title, String xAxisLabel, String yAxisLabel, Dataset data) throws IncompatibleDatasetException {
                  check(data, IntervalXYDataset.class, this.chartType);
                  return ChartFactory.createHistogram(title, xAxisLabel, yAxisLabel, (IntervalXYDataset) data, PlotOrientation.VERTICAL, true, false, false);
