Drawing function

[Mickael DREAN <mickael drean laposte net>]

Hi everybody,

 I'm starting to use GTKmm and I would like to know how to draw a 
function (like a sinus for exemple). I tried some tutorials and I learn 
how to draw a rectangle, a line, etc... but I want to draw a function 
from a tab with values.

 Could someone give me some help?

Thanks

Mick
