Re: [Matplotlib-users] Is there a 3D version of the quiver plot?

[Brickle M. <bri...@gm...>]

Thanks.   I had a quick read of the thread linked, if I was a 
stronger/better programmer I would see if I could contribute.

For now I plan calculate/plot the angle between the normal and each the 
X,Y,Z planes.  I hopefully the 3 subplots will visually convey 
sufficient information.

Brickle.
