Now that those two funtions are in place, it's child's play to use them. I am already using them
heavily in the company I work for, VA Linux Systems,
and on my own site,
and here on PHPBuilder to graph traffic flows.
There's so much more you can do with this class, that I can't touch it all here. If you do write up new wrapper classes, please
submit them to the code archive. My next project with this class is to extend it so it can do stacked bar charts.
