If you make any improvement to the script, please send the author your copy to be included for the next versions. Current support includes GIF, PNG, JPEG and WBMP backgrounds and graphing of multicolor lines based on the data provided. Using PHP, DynaGraph accesses a MySQL database, and uses the results to plot information to a bar graph in the GIF format, using gd1.3. Line, Point, Area, and Bar Graphs are supported. Legends, shading, and zero-axis support.
Output is highly configurable.
Refer to examples for illustration of use. Requires GD and TTF support. Tested on PHP4.0.2. Iit supports vertical and horizontal chart drawing, and custom bar bitmaps. It is still a beta and is part of a whole libary.
