[ncl-install] problems with gsn_csm_contour_map

[David Brown]

Hi Claude,

This question is not really appropriate for the ncl-install group,  
which is focused on ncl installation issues. You should submit it to  
ncl-talk, where programming issues are discussed. That said, it  
appears to me that either there is some missing data in your data  
variable (var_to_plot), or else you are drawing something over the  
plot that is white in that location.
You should try to eliminate possibilities by simplifying your plot in  
various ways. Does the white spot still appear if you put
exit()
immediately after the gsn_csm_contour_map call?
If so you should look at your data.
