Does anyone know of a freeware module to implement a dynamic graphing function on a website, so that a website can produce a graphically plotted function based on user input?

It shouldn't be hard to write a crappy PHP script that passes a function to gnuplot. Example: http://meta.wikimedia.org/wiki/Gnuplot

Maybe this could help: Physlets

It's a set of scriptable java applets intended for use in physics education. They work great even on crappy hardware (100mhz range - I unfortuantly have some experience in there usage with such hardware).

Anyway, among other things, there is a set of applets dealing with graphing data, functions, etc.

They are free for usage in non-commerical and educational enviroments.

jGraph might work if you're willing to use a Java Applet. http://www.jgraph.com/

If the routine causes any appreciable slowdown I'd prefer such a function to be user-end rather than server-side, if I were webmaster. In that case, a Java Applet wouldn't be a bad thing; anyone who wants to see the graph can pay that very affordable price.
