[Matplotlib-users] quiver2

Hi,

I am tring to figure out how to use the c argument to the quiver2 function.

I want to be able to color my arrows proportionally to their size.

I have tried this and it doesn' t work as I imagined:

c =3D sqrt((array(u)-array(x))**2+(array(v)-array(y))**2)

quiver2(x,y,u,v,c)

the docstring on quiver2 is not clear on how c works, any help will be
appreciated.

thanks,
