[ncl-talk] Page Orientation with WRF Panel Plots

Thanks for providing the files, Katie, it looks like there's a bug, and I
admit I'm stumped by this one because "portrait" mode should have been the
default with your plots, since the panel area is higher than it is wide.
There are some cases where your plots suddenly go into landscape mode, for
example if I add this:
pnlres at gsnPanelBoxes = True
This resource draws a red box around each object in a panel plot so you can
see how much room it is taking up. Sometimes there's "invisible" white
space around a plot (like with a blank title) and this resource helps you
see those.
A quick fix is to add this resource to your panel plot:
pnlres at gsnMaximize = True
Finally, you can remove the pltres at gsnPaperOrientation setting, because
this is likely having no effect.
HOWEVER, after having said all this, I decided to create a "gsn" version of
this script, to see if it handled the paneling a little better. The
wrf_contour/wrf_map_overlays procedures are really tailored do to single
plots with nice titles, and are not easy to customize when you want to
throw them in a panel.
Please see the attached "gsn" version of the script. I use
"wrf_map_resources" so you can get the same map projection as what's
defined on the file. But, I then use gsn_csm_contour_map to plot the data.
One thing I noticed is that with the "gsn" version, you now get US states
for every plot. I'm not sure if you wanted this or not?
