Function grapher, Opera application V1.4 Jul 2, 2006 12:17:03 AM

A large widget (1024x768+ required) with tabs. Plot complex functions and provide scale. Simply type 2x*sin{x-3}*cos[x^2]/sqrt|x| to see what it can. From version 0.3 it support dragging canvas.

Outstanding tool! I've been into radio engineering for years. This tool is indispensable for anyone with a pressing need to quickly assess how a set of functions behave within certain boundaries, when MS Excel or other math packs are out of reach.

P.S.: Here's what it can do :smile:

Good widget, but you need to make function of saving images like in functions2d.

Works fine here in debian sid.
It's a very nice widget by the way.

I get an error every time I try to get this widget. Could it be because i'm using linux (Ubuntu 6.10 LTS)?

thanks for feedback. I'm away from home, so it's extremly dificult to change anything. Anyway I hope I will improve it in near future.

this ones good...but
-i dont like that the axis is scaled in 2.5 steps by default and
-the options/settings window on the right is a little to wide

despite those few things the widget is good and definetely better than the other one ..........functions2d

greetings basti
