Radar Chart - Problem with implementation

ahe

Hello

I try to make Radar Charts work.
It seems that radar charts are not really supported by BIRT. But in the svn-package
"org.eclipse.birt.chart.examples" the package "radar" is included.

So I build it with the ant-script, now I have the jar file "org.eclipse.birt.chart.examples_2.6.0.qualifier.jar".

I tryed to write a radar chart:

public Chart createRadar() {
ChartWithoutAxes cwoa = ChartWithoutAxesImpl.create();
cwoa.setType("Radar Chart");
cwoa.setSubType("Spider");
cwoa.setDimension(ChartDimension.TWO_DIMENSIONAL_LITERAL);

TextDataSet categoryValues = TextDataSetImpl.create( new String[]{"New York", "Boston", "Chicago", "San Francisco", "Dallas"});
NumberDataSet seriesValues = NumberDataSetImpl.create( new double[]{54, 21, 75, 91, 37});

// X
Series category = SeriesImpl.create();
category.setDataSet(categoryValues);

SeriesDefinition sdX = SeriesDefinitionImpl.create();
cwoa.getSeriesDefinitions().add(sdX);
sdX.getSeriesPalette().shift(0);
sdX.getSeries().add(category);

// Y
RadarSeries radarSeries = RadarSeriesImpl.create();
radarSeries.setDataSet(seriesValues);
radarSeries.setVisible(true);

SeriesDefinition sdY = SeriesDefinitionImpl.create();
sdX.getSeriesDefinitions().add(sdY);
sdY.getSeries().add(radarSeries);

return cwoa;
}

I always get the same exception:

So I added in "plugin.xml" in "org.eclipse.birt.chart.engine.extension_2.5.2.v20100121.jar" the lines:

<modelRenderer
renderer="org.eclipse.birt.chart.examples.radar.render.Radar"
series="org.eclipse.birt.chart.examples.radar.model.type.impl.RadarSeriesImpl"/>

<datasetProcessor
processor="org.eclipse.birt.chart.extension.datafeed.DataSetProcessorImpl"
series="org.eclipse.birt.chart.examples.radar.model.type.impl.RadarSeriesImpl"/>

but it also does not work yet. So what I have to do? Can anybody help me?
