Hi, I've trying to assigning color to the arrows according to the vector magnitude. I used set, but I guess to use a set, I need the specify which is the magnitude of the arrows, but I don't know how...
I tried used functions like quiverwcolorbar, but there's NaN in the data, so it doesn't work for some of them.

Yes I have. I tried with quiverc2wcmap 'cause I have NaNs in the data, but its returns a message error : Subscript indices must either be real positive integers or logicals...

You remove NaN's and send only numbers then. Simple.
And I have checked with quiverc, it is working though there are NaN's. Have you tried the above link? It is quiverc not quiverc2wcmap.

I have the same problem for quiver 2D.
