PHP Graphing LibraryPHPGraphLib

Lightweight PHP Graphing Library

PHPGraphLib is a lightweight PHP-based graphing library that creates slick PHP graphs for incorporation into a website or application. PHPGraphLib is free to use for personal use, and can be used for a small fee commercially.

PHPGraphLib is a PHP 4.3+ friendly object-oriented class that has powerful customization features, allowing you to generate the perfect bar, line, stacked bar, or pie graph for any application. Used with dynamic data, PHPGraphLib allows easy visual interpretation of sophisticated data sets. Simply feed PHPGraphLib an array of data points, and it will generate a .png chart of your data.

If no customizations are made, PHPGraphLib adjusts the scale and axis of the graph to fit any data, including large numbers, decimal numbers, and negative numbers. PHPGraphlib currently supports up to 5 datasets on one graph or chart.

NEW You can now use the PHPGraphLib Remote API. No need to download the client library - create graphs remotely for use on your website or application. Use any language! PHP is not necessary!
