Re: gsn_csm_pres_hgt_vector

It sounds like you are having draw order issues, although I do not
understand why the wind field would not draw with your first example
coding set as opposed to your second. Have you tried implementing any of
the draw order resources?:
http://www.ncl.ucar.edu/Applications/draworder.shtml
Specifically, cnFIllDrawOrder and vcVectorDrawOrder?

Those two resources should take care of any masking of the vector field
by the filled contour field as in your last example.

If the draw order resources do not help, please send a simple
easy-to-read version of your script to ncl-talk so that the community
can take a look.. Adam
