Re: Problems using Charts

[venkata guddanti]

Hi Sven,

There is a bug in the chart rendering where it is expecting a maxYValue and
minYValue. The following will fix chart:

       @Override
       public Double getMaxYValue()
       {
           return 200000.0;
       }

       @Override
       public Double getMinYValue()
       {
         return 0.0;
       }

Per documentation you do not need to specify these. The min value should
default to 0.0 and max value should be 120% of the max of the yValues. Can
you please log a JIRA issue for this? I will submit a patch.

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;
    }
}
