[SOLVED] Reload GD without reloading the whole page

[guyfromfl]

I am working on this calculator for the company I work for.  It graphs the variable speed table you can program into the engine.  The gray line is the factory default settings and the blue is the user defined speed table.

 

Right now both the default and user defined are hard coded into an array so to change the blue line you have to change the php code...

 

What I want to do is be able to enter a new value into one of the CV textboxes and alter the gd png without reloading the entire page. 

 

there would be alot of variables being passed and I know there has to be a better way.

 

Any suggestions??

There is no way to do this without Flash or AJAX. Note AJAX works well with PHP, and for example if you use JS to hand the .. onChange on those value boxes, it'll call the GD library and update the page without refreshing it. It shouldn't be too hard to implement, more work than difficult for this step.
