Publisher review:JpGraph is a Object-Oriented Graph creating library. JpGraph is a Object-Oriented Graph creating library for PHP >= 4.3.1. The library is completely written in PHP and ready to be used in any PHP scripts (both CGI/APXS/CLI versions of PHP are supported).
The library can be used to create numerous types of graphs either on-line or written to a file. 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.
