simple plotting program

[Artemio <theman artemio net>]

Hello everybody,

I am interested in writing a simple program that would plot somy x-y graphic 
with about 0.5 sec update.

So, there should be only two widgets (I think) - window and drawingarea or 
something like that.

Could you possibly give me some points to start from?
Or maybe some draft piece of code?

I have some basic skills in Gtk-perl, but I plan to write this program in C.


Thanks for any support.

Artemio.
