Ok. So I decided to post a link to my ut stats site with the imagemap.

Basically, you can mouse-over one of the graph-lines and "hover" the mouse there for a sec, and the value of that point gets displayed.
The change to make this happen is very simple. I enclosed the "graphs.php" file inside a function so it can also be included in the matchstats.php file. I needed to replace the "include" statements in graphs.php with "include_once". Then, I put if-statements around all the graphics functions (imageline, etc).
In short, the same code that you use to generate the graphs is the same code that is used to generate the image-maps. If you add another type of graph or something, the image-map should just "work".
An imagemap can create a larger html page, but I did not want to go through the effort of making it a configure option as to whether or not we wanted to enable them or not.
