[Matplotlib-users] quiver aspect ratio

2008-09-17 Thread jason-sage
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
