[Glade-users] how to draw curves


Hi all:
My application is using gtk to design the GUI for an Arbitrary/Function Generator. So I need to draw lots of 
curves, including sine wave, ramp wave, pulse wave, noise wave......and their modulation waves, e.g. the AM, 
FM, PM, FSK and so on.
My problem is that I haven't found a good method to draw these waves. I have used GDK to draw sine wave on 
the GtkDrawingArea. But I found this method is a little complicated especially when I draw the modulation 
waves. Is there a good way to draw curves ?
Any help would be appreciated.Thanks
