Thanks for the answer, John and Jouni.
Okay, Line2D works. However, it appears to work in point (or is it pixels?) only. It doesn't accept xycoords="figure fraction" as an option. How can I specify xy as a fraction of the figure size?
I read the transform cookbook cited by Jouni. I am afraid I am lost what that does....
Regards,

are not currently supporting (but should) is the zorder for
Artists in the Figure. So if you have an Axes in your plot
and you want the line to go over it, you'll need to do
something like Jouni suggested so the line will be drawn
above the Axes.--------------------------------------------------------------
