Libchart is not intended to be the most feature-complete chart library. If you need more functionality, you should have a look at the following software:
- Gnuplot: the most complete free software for making 2D and 3D graphs of data and functions. Caution: gnuplot is an command-line driven software that must be called externally from PHP.
- Artichow: PHP plotting software which produce nice graphs (french-only).
- JpGraph: extensive PHP plotting library, free for non-commercial use only.
