Re: CurlyVectors and gsn_csm_vector_scalar_map

Hi Josh,

I was able to reproduce the problem using your dataset. I have a filed a ticket on this, NCL-1501. It almost looks like these "x"s are some kind of debug feature, meant to show the location of something. But, they don't appear on every vector, so this is puzzling.

Hopefully Dave will be able to look at this, maybe next week.
