This is currently only available for contours. We have it on our list to do this for vectors, but it could be awhile before we get to it. However, you shouldn't need this in your case.

I followed the convention for a 2 deg lat/lon grid, since NAM is on a lon2d/lat2d grid. I used gsnAddCyclic = false, declared my vfXArray and vfYArray, and used TriangularMesh for my grid, the same settings I used for plotting the vorticity, which showed up fine. I am thus stumped why the winds won't show up. Any advice is most appreciated.
