Are you sure you are running the same version of JFreeChart on both platforms? In 0.9.17 the way labels are generated on the pie charts changed, so maybe you are running 0.9.17 on Linux.

Yes , Same versions of JFreeChart - 0.9.16 is running on both platforms.
But I am not getting it on Linux.

Hi Dave Gilbert,

I' ve installed linux version of JFreeChart - 0.9.16 on Linux and windows version of JFreeChart - 0.9.16 on windows. And also we purchased developer's guide from you. In developer's guide I found the syntax for labling : plot.setSectionLabelType(Pie3DPlot.PERCENT_LABELS);

I think Linux version of JFreeChart is different from windows version, even is has same version names.

Can you please provide the solution for it....

Thank you & regards
Subahni

The two archives (jfreechart-0.9.17.zip and jfreechart-0.9.17.tar.gz) are built from the *same* source code, I promise. The script that is used to build the archives is included in the distribution (ant/build.xml) if you want to see how it works.

So, to figure out your problem you will need to explain in more precise detail what is going wrong on Linux. Are you seeing any error messages?

Its giving following error:

Generated servlet error:
[javac] Compiling 1 source file
[javac] /home/jboss-3.2.3/server/default/work/MainEngine/localhost/JFreeChartNew/mypie_chart_jsp.java:113: cannot resolve symbol
[javac] symbol : variable PERCENT_LABELS
[javac] location: class org.jfree.chart.plot.PiePlot
[javac] plot.setSectionLabelType(PiePlot.PERCENT_LABELS);
[javac] ^
[javac] 1 error

Can you please provide the solution for it....

And also, I have tested with following code to check variable PERCENT_LABELS is exist or not in PiePlot object. That variable is there in PiePlot object...

Pie3DPlot plot = (Pie3DPlot) chart.getPlot();

java.lang.reflect.Field[] f = plot.getClass().getSuperclass().getDeclaredFields();
for(int i=0;i<f.length;i++){
System.out.println("declared fields in PiePlot object "+f.toString());
}

Thank you & regards

Hi Subhani,

I just checked this on the two versions of JFC that I happen to have around. Plot.PERCENT_LABELS exists in JFC 0.9.15, but it has been removed in JFC 0.9.17.

You have to change your mypie_chart JSP page. You need to make it use org.jfree.chart.labels.StandardPieItemLabelGenerator, with a format string.

In the format string:
{0} is the key of the data item,
{1} is the value,
{2} is the percentage.

So you could use "{0} - {2}" for example, as a formatstring.

HTH

There is some problem in your environment, but I do not know what it is.

Subhani,

Make sure you only have one JFreeChart jar in you classpath. Look in your ear's, war's, and in your lib directory under your server config. This type of thing has caused me all kinds of headaches.
