JpGraph

Author: Vo.Aug.

this is a really big and great library with tons of features. easy to use, very nice documentation. this is one of the best free libraries i found. but unfortunately i found that using the library in any of my projects will break licenses. because its qpl licensed you could not offer a preconfigured bundled version with your software. you have to offer patches and can't redistribute it with gpl software. so, sorry, can't use it. :(

This script is great! The boat-load of examples could be easily customized to make your own charts within minutes. The documentation is pretty good too. The only thing missing is gradient fills within pie-charts... otherwise I think they covered what you need to start making great graphs/charts fast and easy.

I have been using JpGraph for over a year and am very impressed with the power and flexibility. It is easy to use and allows on-the-fly image generation. I use it by pulling data from a MySQL database to create dynamic information. I was so impressed that I recommended to my company to include as part of a commercial software package (commercial licensing is available through the website).

I recently re-wrote my entire website in PHP, just in order to accomodate the features provided by this class! And it was well worth it... The class in incredibly powerful and allows the highest level of customisation. With support for TTFs as well as a very handy caching function (outputs generated graphs as files that can be cached direct on your server), it comes very highly recommended! Just try doing anything like it in ASP!
