[ncl-talk] vector polymarkers

[Manisha Ganeshan]

Hi Dave,

Thank you for your email. This is very useful!
I'm unable to overlay the wind vectors on the map though. It seems like
this function is independent from the map function, unlike
gsn_add_polymarkers.
I'm attaching my script. Wondering if there's an easy fix that I'm not
seeing.

Thanks,
Nisha
