GraPHPite is a highly customizable utility written in OO PHP for creating charts or graphs (Bar, Area, Pie, etc).
Users are encouraged to switch to PEAR::Image_Graph which is based on GraPHPite source. GraPHPite is in maintenance only state.
It doesn't work. The docs mention a downloadable zip file, but only an exe is available (not much use on my CentOS server). However, having "installed" from the exe, it put stuff under the Programs directory - certainly not where I'd develop web content. Having moved the directory structure to a directory on my server, nothing worked so I gave up. I hope you get it all fixed and docs updated soon, the project sounds interesting and with potential.
Thanks for Graphpite, it's excellent!
Very simple and usefull.
