Hello Rick,

I think the easiest thing would be to use a GnomeCanvas item. It looks a
bit daunting at the beginning, but it really is the ideal solution. You
can use a drawing as a background, eg. with the axis and grid, then draw
with a GnomeCanvasItem of type Line, and draw your graph.

Find the GTK/Gnome Application Development manual (GGAD), there is a good
introduction to the use of the GnomeCanvas.
