[Matplotlib-users] quiver aspect ratio

[<jas...@cr...>]

Recently I noticed that the quiver plots all make the arrows as if the 
plot had aspect ratio 1.  See, for example, the documentation for quiver:

 In all cases the arrow aspect ratio is 1, so that if *U*==*V* the
    angle of the arrow on the plot is 45 degrees CCW from the *x*-axis.


This seems to make the plot pretty useless if the aspect ratio is not 1, 
since then the slopes of the arrows do not match up with the coordinate 
axes.  What is the reason for this design decision?  Does it have to do 
with the arrows distorting if the aspect ratio is not 1?  At one time, 
there was talk of adding a line version of quiver (as opposed to the 
patch version there now).  See 
http://article.gmane.org/gmane.comp.python.matplotlib.devel/1885.  Has 
that happened?  I suppose a line version would allow different aspect 
ratios.

Is there an easy way to get a correct quiver plot (i.e., correct slopes) 
now if the aspect ratio is not 1?

Thanks,
