Have you tried the FXCanvas in FXRuby?

I have no idea if you'll get it to do what you need

If that gives you problems, it's not hard at all to draw lines in the
FXGLCanvas, it would just seem like overkill to draw a 2d graph in OpenGL.

FXRuby comes standard in the one-click prag-prog installer for Windows.
