JpGraph is a fully OO (Object-Oriented) Graph creating class library for PHP >= 4.3.0. The library can be used to create numerous types of graphs on-line. JpGraph makes it easy to draw both "quick and dirty" graphs with a minimum of code as well as complex graphs which requires a very fine grained control. The library assigns context sensitive default values for most of the parameters which minimizes the learning curve. The features are there when you need it - they don't get in your way! Check the JpGraph website for more information about the class library and usage. The JpGraph library has been ported with permission of the author for usage in the mambo open source content management system. Porting of this version of JpGraph has been done by Wilco Jansen.JpGraph is released under a dual license.
