Google does not come up with much.
I have seen simple AJAX examples...but none related to graphing classes.

I am a bit new at combining php with javascript with regards to image creation.

basically, I want the user to enter variables and have a graph generated without a full page reload on the same page...
kind of an  interactive graphing web  tool.

any examples  of this sort are appreciated  :)

Surely it would be much simpler to just use have javascript to set a placed image to a new (or the same) location - this image is then generated by JPGraph et al with no modification to code. I have been using this technique for years to make server calls without page refreshing. (Well, that or an invisible frame/iframe/layer)

HTH,

Mikey

ok, so you have html like

<img src="/images/graph.php" name="img">

and you have js like

// some event that triggers the script
document.images['img'].location = "/images/updated_graph.php";

And php makes your graph.  Using whatever classes you choose.

HTH,

Mikey
