Hi, I'm new in matplolib code, I have matrix of winds vectors derivated from quiver introducing U,V components,and positioning these in a sorted grid X,Y with the command quiver (x, y, u, v,color='r') It's possible to put in the figure the barbs to every arrow vector or scaling the arrow with the values of its lenght derived by >>> r = sqrt((U**2)+(V**2)) Thanks a lot to averyone give me help >----(^_^)----<
