Re: [Matplotlib-users] How to determine position of axes after imshow?
From: Mark Bakker [mailto:mark...@gmail.com] Sent: Thursday, August 09, 2012 14:43 I am glad to see you can reproduce the error, Stan. I am running whatever is default with a PythonXY installation (sorry my windows machine is at work). Strange behavior. The code works fine on my mac (PyQt4 backend) with all options (show,draw,pause). Should we file a bug report? Mark I'd say that it's your call, but what you found does seem appropriate for a bug report. -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

Re: [Matplotlib-users] How to determine position of axes after imshow?
From: Mark Bakker [mailto:mark...@gmail.com] Sent: Tuesday, August 07, 2012 06:42 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]])) I modified your script to test show(), draw(), and pause(); it's attached.

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? When I type the commands in at the IPython prompt it works most of the time (on Windows), but it never works when running the file. What in the world could be different? mp version 1.1.0 on both systems. Are you using the same backend on both systems? Perhaps when you run the script within IPython on your Windows system, the show() call is not triggering a draw. You can force drawing by calling draw() before show(). I hope that helps. -- Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.
