Re: gsn_csm_vector Vs gsn_vector

Dear Mateus,

Thanks for your response. As you said there are some difference between
graphics generated with *gsn_** functions and those generated with *
gsn_csm** functions. But when we plot with *gsn_csm_vector* functions, the
Hadley circulation never comes to reality. It gives entirely wrong picture (
It never gives the ascending and descending motion. It gives some horizontal
vectors). But when we plot with *gsn_vector* functions, it gives correct
plot. But the problem with the *gsn_vector* function is that it never gives
the coordinate in X and Y axis. In that case how I can resolve my issues.

Thanks in advance
