Bug when saving in PNG?

Hi,

I have a problem when saving my plot as a png. The horizontal lines, which I
inserted via
axhline(y=0.136, xmin=0., xmax=1, color='black',ls=':')
axhline(y=0.094, xmin=0., xmax=1, color='black',ls=':')
are not displayed right in the png file. Saving in pdf works perfectly. I
enclosed the two files in this email.

Is there a way to fix this problem?

Thank you for your help,
Markus

This appears to be working fine for me with svn matplotlib – what version are you using? See also: http://matplotlib.sourceforge.net/faq/troubleshooting_faq.html#report-a-problem for information about how to obtain version and other configuration information.

Hi,

I’m using the code copied straight from the simple tkagg animation example at:

http://matplotlib.sourceforge.net/examples/animation/simple_anim_tkagg.html

It starts up fine and I can see the moving sine wave, however, after about 15 to 20 seconds the plotting window freezes showing “Figure 1 (Not Responding)” and that’s that. Adding an additional line, “print i” just before “line.set_ydata(…)” shows that even once the window has frozen the code is still being executed. Has anyone had this problem and solved it?

I’m on Windows Vista running:
Python 2.5.1 (r251:54863, Apr 18 2007, 08:51:08) [MSC v.1310 32 bit (Intel)] on win32
Matplotlib
v0.98.3

numpy v1.2.0
Tkinter $Revision: 50704 $

Thanks

I am not able to reproduce this with 0.98.3 either, with the two example lines you've shown. Perhaps it's an interaction with some other part of your script? Can you provide a complete example that duplicates this problem? Or are those two lines enough for you?

Mike
