Re: help ploting graphic using "gsn_contour_shade"

Hi Rosa,
I do not believe that the problem lies within the gsn_contour_shade
function... The gsn_add_cyclic error message is indicating that your
longitude range is not 360, and to set res_at_gsnAddCyclic = False. Does
your data span 360 degrees? And if not, have you tried setting
gsnAddCyclic = False?
