DifferenceChart with more than 2 series

[DeO]

Hi everybody,

i have played a bit with the difference chart, to create a certain look for the stroke. See image below.



Is there a way to use multiple series in a difference chart? So that series 0 and 1 are "connected", series 2&3 are connected, series 4&5 are connected?

Code: Select all

       // ia
        XYDifferenceRenderer iaRenderer = new XYDifferenceRenderer(iaColor ,iaColor , false);
        iasProbeRenderer.setSeriesPaint(0, iaColor );
        iasProbeRenderer.setSeriesPaint(1, iaColor );
        chart.getXYPlot().setDataset(0, datasetIA);
        chart.getXYPlot().setRenderer(0, iaRenderer);

        // iv
        XYDifferenceRenderer ivRenderer = new XYDifferenceRenderer(ivColor, ivColor, false);
        chart.getXYPlot().setDataset(1, datasetIV);
        chart.getXYPlot().setRenderer(1, ivRenderer);
        ivRenderer.setSeriesPaint(0, ivColor);
        ivRenderer.setSeriesPaint(1, ivColor);

edit: not solved

now i get an indexOutOfBoundsException in :
