Re: [Matplotlib-users] How to determine position of axes after imshow?
I tried a few things and found out that doing a pause works. So why does a pause work, but a draw() or show() does not? This all on Windows using the standard PythonXY installation. Here is the code that works (testimage.py): from pylab import * c = ones((10,20)) ax = imshow(c) pause(0.01) print ax.get_axes().get_position() Running from IPython: run testimage Bbox(array([[ 0.125 , 0.2417], [ 0.9 , 0.7583]])) On Wed, Aug 1, 2012 at 8:56 PM, Stan West wrote: > ** > > *From:* Mark Bakker [mailto:mark...@gmail.com] > *Sent:* Monday, July 30, 2012 05:54 > > Hello List, > > I am trying to determine the position of the axes after an imshow and am > having problems. > I get a different answer on my Mac (the correct answer) than Windows (the > wrong answer). > > [...] > > Any thoughts?

[Matplotlib-users] zoomed_inset_axes bbox_to_anchor not working
Hi everyone,
I'm trying to make a zoom of a single plot. The problem is that the zoomed
axes yticks overlap with the yaxes so I tried to use the bbox_to_anchor
option in the zoom:
axins = zoomed_inset_axes(ax,
3,bbox_to_anchor=(0.4,0.4),bbox_transform=ax.transAxes, loc=2)
with different (x,y) parameters, but it's not working.
I also tried to move the figure by hand:
box = axins.get_position()
print box
axins.set_position([box.x0+0.5, box.y0,box.width, box.height])
box = axins.get_position()
print box
and I see that box numbers changing, but not in the plot.
Can anyone guess what I am doing wrong?
Thank you all!
PS: The full code for this plot is:

"""

fig = p.figure(figsize=(12,8))
ax = p.subplot(111)

ax.plot(z[0],Dl_lflrw(z[0],0.3,0.7),'k--',label=r'Dl $\Lambda$FLRW')
# mean data values
ax.plot(data.redshift,data.distance,'r.',label='SCP data')
p.xlabel('z',fontsize=18)

p.grid(True)

[Matplotlib-users] How to determine whether a window is closed?
Hi, In matplotlib, is there a way to check whether a window related to a figure has been closed by user? x=[1,2,3] fig = plt.figure() fig.show() plt.plot(x,x) plt.draw() later in the code, I want to make draw some other line, possibly on the same figure. I can switch to the preivious figure by plt.figure(fig.number) but it seems that even if fig has been closed by the user, this will still work because the information stored in fig is still accessible. Then, this fig.number would actually point some other picture. So, is there any state information in fig that would tell whether the window of fig has been closed by user?
