Re: adding polymarkers to hdf4sds_5.ncl?

Correct, plot2 is overlaid on plot, then plot3 is overlaid on plot. But
I just noticed something: You're using gsn_polymarker, and I think
whenever you do paneling and/or overlaying you'll want to use
gsn_add_polymarker to make sure the polymarkers get attached to the
correct plot.

(As gsn_add_polymarker is more versatile than gsn_polymarker I always
use the former no matter the situation.)

Try using gsn_add_polymaker and attach the polymarkers to plot, leave
the tfPolyDrawOrder resource in there, and see if that works. Adam
