[ncl-talk] Problem with panel plot

[Dave Allured - NOAA Affiliate]

Please reply to the mailing list, not to me personally.

I see another problem.  You have gsn_open_wks inside the loops making 18
plots.  The workstation must be opened only once, before the start of the
loops, if you want to make a panel plot.  Please move that statement to
above the loops, and see what happens.

Also when paneling, the Draw and Frame resources should be set to False
when making the individual plots inside the loop.  Otherwise, each plot
would get drawn twice in the output file.  See how this is done in the
panel examples.
