Problems using Charts

[Sven Wagner]

Hello,

I'm trying to use the tr:chart component. The demo works fine as it is, but
when I try using my own classes with the demo data, it only shows pie charts
(and funnel charts). for all other types I get an empty space. I have tried
simply using the demo as it is and not rendering the the table which has the
same effect. Can anyone help?

Thanks,

Sven

P.S. Sorry if I spam you with this problem, I tried sending it twice
already.


These are my classes:

public class MyChartModel extends ChartModel{

   @Override
   public List<String> getGroupLabels() {
       // TODO Auto-generated method stub
       return Arrays.asList(new String[]{"June", "July", "August",
"September","October"});
   }

   @Override
   public List<String> getSeriesLabels() {
       // TODO Auto-generated method stub
       return Arrays.asList(new String[]{"Previous", "Target", "Actual"});
   }

   @Override
   public List<List<Double>> getYValues() {
       ArrayList<List<Double>> _chartYValues = new
ArrayList<List<Double>>();
         _chartYValues.add(Arrays.asList(new Double[]{135235.0, 155535.0,
141725.0}));
         _chartYValues.add( Arrays.asList(new Double[]{106765., 131725.,
127868.}));
         _chartYValues.add(Arrays.asList(new Double[]{108456., 119326.,
139326.}));
         _chartYValues.add(Arrays.asList(new Double[]{136765., 147265.,
184349.}));
         _chartYValues.add(Arrays.asList(new Double[]{107868., 113968.,
174349.}));
         return _chartYValues;
   }

}

----------------
public class ChartBean {
   MyChartModel value=new MyChartModel();

   public ChartModel getValue(){
       return value;
   }
}
