Re: zooming in on a map plot

Hi Nicole,
If it didn't work for your WRF data I assume you are using the various
WRF plotting functions to create the plots. The wrf* routines set a lot
of things up automatically for you behind the scenes, which is
convenient if you're happy with how they set things up. However, it
sometimes is not the easiest to alter settings with regards to the wrf*
routines. I do not regularly plot WRF data, but I do not know of a way
to automatically zoom in on a region while using the wrf* plotting routines.

I think your two options are:
1) subset the data using region_ind (which I know you'd rather not do):

2) Attach your 2D lat/lons as attributes to the array to be plotted, and
create your plot using regular NCL plotting functions
(gsn_csm_contour_map for example).. See here:
