Using multiple renderers causes an Exception

tdk · Post by **tdk** » Wed Feb 07, 2007 8:48 am

Folks'es,

i have a question/problem when using different renderers for a chart.
i have 4 XYSeries which i want to show in the following way:
- series 1, 2, and 3 should be drawn with a XYStepAreaRenderer
- series 4 should be drawn with a XYStepRenderer

however, when the plot is drawn i get the following exception:

Code: Select all

Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: Index
 'index' out of bounds.
    at org.jfree.chart.plot.XYPlot.getDomainAxisForDataset(XYPlot.java:2697)
    at org.jfree.chart.plot.XYPlot.drawDomainMarkers(XYPlot.java:2851)

    at org.jfree.chart.ChartPanel.paintComponent(ChartPanel.java:1269)
    at javax.swing.JComponent.paint(JComponent.java:1003)

following are the jfree related bits of my code:

Code: Select all

        dataPoints = new XYSeriesCollection();
        dataPoints.addSeries(yellowThreshold);
        dataPoints.addSeries(orangeThreshold);
        dataPoints.addSeries(redThreshold);
        dataPoints.addSeries(values);

        lineChart = ChartFactory.createTimeSeriesChart("", "", "Day+Hour:Minute:Second",
                dataPoints, true, true, false);
        ((NumberAxis)lineChart.getXYPlot().getRangeAxis()).setNumberFormatOverride(new DecimalFormat() {
            public StringBuffer format(double number, StringBuffer result, FieldPosition fieldPosition) {
                return format((long)number, result, fieldPosition);
            }
            public StringBuffer format(long number, StringBuffer result, FieldPosition fieldPosition) {
                result.insert(fieldPosition.getBeginIndex(), ElapsedTime.format(number));
                return result;
            }
        });
        lineChart.getXYPlot().setRenderer(0, new XYStepAreaRenderer());
        lineChart.getXYPlot().setRenderer(1, new XYStepAreaRenderer());
        lineChart.getXYPlot().setRenderer(2, new XYStepAreaRenderer());
        lineChart.getXYPlot().setRenderer(3, new XYStepRenderer());

could there be a relation to the issue described in http://www.jfree.org/phpBB2/viewtopic.p ... +renderers?

Did you make any calls to mapDatasetToDomainAxis()?

No, i had not. but now i have:

Code: Select all

        xAxis.setLabelInfo(bands);
        lineChart.getXYPlot().setDomainAxis(0, xAxis);
        lineChart.getXYPlot().mapDatasetToDomainAxis(0, 0);
        lineChart.getXYPlot().mapDatasetToDomainAxis(1, 0);
        lineChart.getXYPlot().mapDatasetToDomainAxis(2, 0);
        lineChart.getXYPlot().mapDatasetToDomainAxis(3, 0);

        XYStepAreaRenderer renderer = new XYStepAreaRenderer();
        lineChart.getXYPlot().setRenderer(0, new XYStepRenderer(), false);
        lineChart.getXYPlot().setRenderer(1, renderer, false);
        lineChart.getXYPlot().setRenderer(2, renderer, false);
        lineChart.getXYPlot().setRenderer(3, renderer, false);

but the result is still the same exception:

Code: Select all

Exception in thread "AWT-EventQueue-0" java.lang.IllegalArgumentException: Index

OK, I've managed to reproduce the problem now. If you add a renderer to the XYPlot, but don't add a corresponding dataset, this exception is thrown. I've added the following bug to the database, and will look at how to fix this:

Dave,

i don't quite understand this. my data is a XYSeriesCollection which has 4 XYSeries (see initial posting). doesn't that qualify as 4 datasets?

confused,

thomas

No, it is one dataset containing four series. If you want four datasets, you need to create four instances of XYSeriesCollection, and add one series to each.
