[ncl-talk] How to plot a subset of data

[Alan Brammer]

Chances are you don't need to worry about the where statement. Just set the
extent of the map through the plot resources.  Did you look at the examples
page.  https://www.ncl.ucar.edu/Applications/cylineq.shtml  Example 3 is
shows you how.

"You must specify the four limits of the map, however:
res at mpMinLonF
res at mpMaxLonF
res at mpMinLatF
res at mpMaxLatF
It is also required to set gsnAddCyclic to False whenever you plot a
non-global domain. "

Good luck,
Alan Brammer
