Hi Venkata,
thanks for the hint. Unfortunately it doesn't solve my problem. I added the
functions to myChartModel Class but the problem remains the same. Am I
using the tag right? This works fine:
<tr:chart id="myChart" value="#{chart.value}" type="pie"></tr:chart>
This shows a blank space though the border of the box is visible.
<tr:chart id="myChart" value="#{chart.value}" type="verticalBar"></tr:chart>
Would be cool if I could make it work. It's an impressing component.

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.
