I have been working on a new version of the Function Grapher, mostly all new code.

Here is the "Beta" version: http://www.mathsisfun.com/data/function … 0=0&rev1=3

(try the "a" slider at the bottom)

Could everyone give it a good testing and find bugs before I make it live.

Also any suggestions for improvement please

Hi MIF;

Can we get an Undo button?

What will it do, go back one character at a time?

Hi;

Maybe undo the last change, could be a zoom or any setting change.

Good idea, interesting coding-wise too no doubt. Will have a look at it.

Hi;

The grapher is working well. I wished that there were a link to it somewhere on the front page.
