Jason,
I have added this capability to the "gsn_csm.ncl" script. What you'll
need to do is set the resource "tmYRTickSpacingF" to whatever spacing
you want on the right height axis. Since the code wants to use "nice"
values, you should use a nice round number, like 1, 2, 3, etc:
res = True
...
res@tmYRTickSpacingF = 1
plot = gsn_csm_pres_hgt(...,res)
You must first download a new "gsn_csm.ncl" and "gsn_code.ncl". You can
do this from:
http://ngwww.ucar.edu/ngdoc/ng/ug/ncl/gsun/scripts/gsn_code.ncl
http://ngwww.ucar.edu/ngdoc/ng/ug/ncl/gsun/scripts/gsn_csm.ncl
These are still in test mode, so you may want to make copies of your
original versions of these files first.
Also, the code from the above links may look funny, because the lines
do not have clean breaks after them. I'm having our web folks look
into this. Meanwhile, the code should look fine if you save it to a
file.
