Re: gsn_csm_vector Vs gsn_vector

Hi Sabeerali,

As you can see in the section 2.2 of the graphics manual (
http://www.ncl.ucar.edu/Document/Manuals/) there are some changes between
graphics generated with *gsn_** functions and those generated with *gsn_csm*
* functions.

Please, take a look in that sections of the graphics manual.

Best regards,

Mateus
