Pie chart Legend format change

piyush · Post by **piyush** » Sun May 07, 2006 2:42 pm

Hi all,
I have a customization to be done in the legends being generated (below the chart) for the Pie charts. I want only the name of the category to be displayed and not the name = value pattern as it currently exists.
If I try new StandardPieSectionLabelGenerator("{1}), it only changes for the labels being displayed next to the pie sections.
Please help me.
Thanks in advance.

Regards,
Piyush

Hi All,
I found out how to do that. It can be done using

Code: Select all

pieplot.setLegendLabelGenerator(new StandardPieSectionLabelGenerator("{0}"));

.

Now I'm facing another problem. If the legend name of any section is too long, then I want to crop it off after some size. Say if my legend name is No of Users in Category X, then I would like to display only the first 10 characters of the above label, followed by trailing spaces. How do I go about it.

Any suggestion / help is highly appreciated.

Thanks in advance,

Regards,
Piyush

For that, you'll need to create your own PieSectionLabelGenerator class (you could start with StandardPieSectionLabelGenerator and modify it as necessary).

Hi,

I try to modify the legend to decrease the lenght of legend labels...
On CategoryPlot or XYPlot on, we can do a setFixedLegendItems(..) to change legends items... But for PiePlot, method doesn't exist... is-there a solution or I do rewrite a custom PiePlot ?

I guess the fixedLegendItems attribute could be moved up into the Plot class...anyone else have any thoughts about that?

What do you display in the legend for the PiePlot? Generally, I hide the legend in this case, because you can easily label the pie sections right on the plot and so the legend is redundant.

It's rigth that I label the pie sections and that the legend is redundant....
I will have a discuss with my training course chief to know if I can not display the legend...

thank you for the response
