Pie Chart Shrinks - Help please...

[raffimd]

Hi,

I have a report, which inturn has 2 subreport, each one has a pie chart in it. I have enabled the legend in the pie chart.

When the data points increases, the legend area grows and the pie chart shrinks...:(

 

Is there any way to mention in the jasper report, so that the pie chart does not shrink and allow the legend to grow outwards instead of growing inwards.

 

Thanks in advance...

All,

Is this a bug?

Did anyone face this problem?

 

Problem:Pie chart shrinks with more data points because of legend.

 

Thanks,

Hi,

 

I don't think there is anything we can do about it.

We draw the chart on a limited area defined by the element in JRXML. Charts have to fit inside there.

 

Thank you,

Teodor

Hi Teodor,

Thanks for the response.

Is it possible to make the legend to grow outwards and make some behavious like stretch with overflow?

 

Thanks,

Unfortunately the behavior you describe (legend grows, so the pie shrinks) is the way JFreeChart behaves. One workaround is to turn the legend off for the pie and then create a subreport with the same data as the pie and place it next to the pie as the legend.

 

You can also try making the chart area siginificantly wider than it is tall, so the size of the pie is determined by the height and there is plenty of room off to the side for the legend.

Hi Barry,

Thanks for the idea. Let me try those options.
