Re: gsn_csm_xy (3 lines on one plot)

Hi Dave,
I'd try setting:
res@xyMarkLineModes = (/"Markers","Markers","Markers"/)
alternatively:
res@xyMonoMarkLineModes = True
res@xyMarkLineMode = "Markers"

For the former I think NCL wants you to tell it how to draw each of your
lines, you have 3 lines, so NCL wants three entries in xyMarkLineModes.

I do find it odd that the default for xyMarklineModes isn't Lines, in
that you would've gotten one line drawn by markers, and two lines drawn
as lines... (It's "NULL" according to the documentation.)
