How to create a dynamic Pie Charts ?

Hi all,

I'm a newbie whose have to create a PieCharts in order to put it on a web site (using JSP, Tomcat). I know that the best way to build dynamic (data coming from db) pie charts is a beans, but I never did a Pie charts before, therefore I'm a little bit in the dark. I've succeed in creating a simple bar charts beans, but I have no idea for the pie charts.

Hope that someone will help me.

Thanks in advance

Have you thought about using third party tools such as Style Reports ?

I've written a pie chart package that does everything but take your mother to dinner, but I didn't use beans. I don't think that pie charts scream "beans" to me personally.As for some help, the Arc2D Class would be a handy place to start.

Maybe you should try Cewolf which is a chart tag library to generate all kinds of charts in a JSP. See http://cewolf.sourceforge.net.Regards,Guido

Hello,

Since morning i was trying to use cewolf 0.8.1. But, didn't got success. I am using Apache 2.0.39 and Tomcat 3.2.2 with jdk 1.3.1.

Just now, i tried with tomcat 4.0.4 without apache configuration and it works fine. But, i need to make it work with the first configuration.

What are the changes i am required to make.

Please guide and help.

Thanks and regards
