[ncl-talk] Script producing two png files, I only want one of them?

[Rick Brownrigg]

Ok, not sure, but at line 235,   "res at gsnDraw = True". This should be set
to False. Apologies for not catching that the first time around.

In general, any of the gsn_xxxx routines draw their graphics immediately
upon being called, unless @gsnDraw and @gsnFrame are set to False.
Normally, this default behavior is what users want, but when doing an
overlay, or a panel plot, or annotating a plot with
markers/text/polylines/etc, its important that these resources be set to
False, so that all of the graphical results can be "accumulated" and output
on a single frame/page/image.
