Pie Chart Percentage Display Problem

[Joanne Li]

As suggested by the previous posting in this forum, I use the following code to display both name and percentage in a pie chart.

PiePlot pp = (PiePlot)chart.getPlot();
pp.setSectionLabelType(6);

However, there is always a "-" sign in front of the percentage (such as -20%). I use the same code for a pie3D chart, it does not show the "-" sign.

Has any of you encountered the same problem?

Any help would be highly appreciated.

Hi,

I am also getting the same problem. Is it a bug? No problem while using pie3D chart.

It is a bug that was fixed in CVS soon after the 0.9.2 release. See this thread for more info:

David,

Thanks for the quick response. However, I cannot find the drawLable() method in the PiePlot class. I downloaded the latest windows version of JFreeChart from http://www.object-refinery.com/jfreechart/ ---0.9.2

Thank you for your time.

Are you sure? Line 828 of the PiePlot.java source file...unless I've messed something up.

David,

Sorry, drawLable() is there.
Where can I download the correct JFreeChart Jar file (corrrected PiePlot class) or I need to rejar myself?

Thanks a lot for you time.

You need to rejar yourself. Alternatively, you can set the 'direction' for the pie chart to ANTICLOCKWISE using the setDirection(int) method. This should restore the percentage labels to positive numbers.
