[Matplotlib-users] problems with autoscale_view
Hello,
If I use autoscale_view than:
* plt.text appears outside x and y coordinates
* and the coordinates starts do not from 0 whereas I use ax.set_xlim(0)
and ax.set_ylim(0)
What did I wrong?
from pylab import *
import matplotlib.pyplot as plt
x = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19,

28, 8, 17, 2, 8, 29, 13, 14, 20, 11, 28, 8]

Re: [Matplotlib-users] plotting an arrow outside of the plot does not work any more
I just remembered that there has been a bug in old version of
matplotlib that annotation_clip parameter is not correctly set when
given as a keyword parameter of "annotate" function. The bug has been
fixed.
http://www.mail-archive.com/matplotlib-users@lists.sourceforge.net/msg15068.html
As a workaround, use
ann = pylab.annotate('',(-1,3.1),(0,3.1),va='center',ha='center',
arrowprops=dict(arrowstyle='<->'))
ann.set_annotation_clip(False)

Stan, if you want, could you try installing the 1.0.0 Sage matplotlib spkg and seeing if that works? You can do it by doing: sage -i http://sage.math.washington.edu/home/jason/matplotlib-1.0.0.spkg (the ticket is http://trac.sagemath.org/sage_trac/ticket/9221 ) Matplotlib 1.0.0 changes how axes labels work, so if you want to do axes labels, then you'll have to also install the patch listed at the ticket.

Hi JJ,
Thanks for the advice. However, the annotation_clip=False addition does
not make a difference to me. I am using Matplotlib from within Sage,
though; not sure if this makes it behave differently.

Re: [Matplotlib-users] subplot2grid weird for non-square shapes
Thanks for reporting. It turns out a (major) bug in gridspec, which should be fixed in r8667 & r8668. You code should work (except the rowspan and colspan needs to be exchanged for ax3 and ax4).

Re: [Matplotlib-users] plotting an arrow outside of the plot does not work any more
I think this change has been there for a while.
For recent versions of matplotlib, the default behavior of annotate is
that, when xycoords=="data", the arrow is drawn only when the
annotated point is inside the axes.
To override this behavior, use annotation_clip keyword parameter.
pylab.annotate('',(-1,3.1),(0,3.1),va='center',ha='center',
arrowprops=dict(arrowstyle='<->'), annotation_clip=False)

Chiara,
As a workaround for Qt4Agg, you can follow p.draw() with
fig.canvas.flush_events().
I think this is a bug that will be fixed easily by incorporating the
flush functionality in the draw method, but I'm not ready to commit to
it yet.
I wonder whether you were using a different backend when you were using
0.99.1.1? Or a different version of PyQt4?
