Dave -- One thing you could do is to make a fake data just for the
purpose of controlling legend.  If the data coordinates are set to be
outside of the plot range, they won't show up in the plot, but you can
then fully control what to show in the legend.  I remember doing that
myself before, which worked okay.

(That's not an elegant solution of course, but I think we all agree
that the legend implementation is something that needs more work at
this point...)
