i am implementing a jsp application and i am looking for packages that allows me to build some nice charts in java using data retrieved from my database . I tried free jspChart but is does not give me nicest jpeg pics that i could insert in my jsp file.

So i am looking for another free package that allow me to have nice and parametrable pics sothat i can modify colors , backgrounds and so on !!

Take a look at JFreeChart:

http://www.object-refinery.com/jfreechart/index.html

It is free (GNU LGPL) and can be used to generate many different chart types.

P.S. I wouldn't recommend JPEG as an image format for charts. You will get better quality results using PNG.

It has built in support for PNG and JPEG (the latter because someone wanted it, I still wouldn't recommend using JPEG). GIF would be very easy to add...Dave Gilbertwww.object-refinery.com

You can use RChart: http://www.java4less.com/charts_e.htmit supports more than 20 types of charts and has a Visual Tool for designing the charts. It can be used as Applet , Servlet or Bean.

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
