Hi, RTFM...indeed it works. However, the axis do not scale accordingly:
quiver([1],[1],[2],[2], angles='xy', scale_units='xy', scale=1) on a TkAgg backend produce a plot with: In [11]: axis() Out[11]: (0.94000000000000006, 1.0600000000000001, 0.94000000000000006, 1.0600000000000001) The display area scales the same way as it does using quiver([1],[1],[2],[2]) (without any other args). It looks like a bug. Xavier > Hi Xavier, > > You can pass some handy keyword arguments to fix that.
