Hi David,

Maybe someone else has a more elegant solution, but
here is what I do:

sage: f(x) = x^2
sage: g(x) = (x-5)^2
sage: fp = plot(f, (x, -10, 10), rgbcolor = (0,0,1))
sage: gp = plot(g, (x, -10, 10), rgbcolor = (1,0,0))
sage: (fp+gp).show()

The plot commands now only create the two plot objects
fp and gp, without displaying them.  The last line
combines them into one plot object and displays it.

Best,
Alex
