Hi Xavier,
I'm sorry. As I don't know a great deal about the nuts and bolts of matplotlib,
I don't think I'm well enough equipped to answer your question. Perhaps someone
else on this list can help out?

Hi,
Well when you plot, imshow or whatever is matplotlib related, the axes
do scale *automatically*.
Why should it be different with quiver?
I do reproduce your error with axis('tight')

Hi Xavier (cc list),
It may be a bug, however I do not know what the default behaviour 'should' be.
You could do:
lims = [-4, 4, -4, 4]
axis(lims)
after calling quiver to see the whole arrow. I did notice that calling
axis('tight')
threw the following error

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]:
(0.94006,
1.0601,
0.94006,
1.0601)
The d
Hi Xavier,
You can pass some handy keyword arguments to fix that. Use the following:
quiver([1],[1],[1.2],[1.2], angles='xy', scale_units='xy', scale=1)
Hope that helps :)

Hi,
I woud like to draw a vector field using pylab.
quivert looks nice but it sould not scale the arrows to fit my use-case.
quiver([1],[1],[1.2],[1.2]) does plot a nice arrow but the head of the
arrow is not at (1.2,1.2).
Is there a way to plot a list of arrows *without* any scaling?
