I also have another gui script where you move a slider around and it changes the colormap, using
axes.images[0].set_cmap() figure.canvas.Refresh() in real time. It works wonderfully most of the time but occasionally goes crazy, spouting a loop like this: Traceback (most recent call last): File "C:\Python25\Lib\site-packages\matplotlib\backends\backend_wx.py", line 1352, in _onClose File "C:\Python25\Lib\site-packages\matplotlib\_pylab_helpers.py", line 28, in destroy File "C:\Python25\Lib\site-packages\matplotlib\backends\backend_wx.py", line 1406, in destroy File "C:\Python25\Lib\site-packages\matplotlib\backends\backend_wx.py", line 1365, in Destroy File "C:\Python25\Lib\site-packages\wx-2.8-msw-unicode\wx\_core.py", line 7198, in Yield wx._core.PyAssertionError: C++ assertion "wxAssertFailure" failed at ..\..\src\msw\app.cpp(680) in wxApp::Yield(): wxYield called recursively Traceback (most recent call last): File "C:\Python25\Lib\site-packages\matplotlib\backends\backend_wx.py", line 1111, in _onSize File "C:\Python25\Lib\site-packages\matplotlib\backends\backend_wxagg.py", line 61, in draw File "C:\Python25\Lib\site-packages\matplotlib\backends\backend_agg.py", line 380, in draw File "C:\Python25\Lib\site-packages\matplotlib\figure.py", line 612, in draw File "C:\Python25\lib\site-packages\matplotlib\axes.py", line 1344, in draw File "C:\Python25\Lib\site-packages\matplotlib\axis.py", line 596, in draw File "C:\Python25\Lib\site-packages\matplotlib\axis.py", line 170, in draw File "C:\Python25\Lib\site-packages\matplotlib\text.py", line 775, in draw File "C:\Python25\Lib\site-packages\matplotlib\text.py", line 317, in draw File "C:\Python25\Lib\site-packages\matplotlib\text.py", line 195, in _get_layout File "C:\Python25\Lib\site-packages\matplotlib\backends\backend_agg.py", line 234, in get_text_width_height_descent File "C:\Python25\Lib\site-packages\matplotlib\backends\backend_agg.py", line 301, in _get_agg_font RuntimeError: Could not open facefile c:\windows\fonts\vera.ttf; Cannot_Open_Resource I'm pretty lost about it :) Thanks, Jack On Jan 17, 2008 6:03 PM, Jack Sankey <[EMAIL PROTECTED]> wrote: > Hello, > > I wrote a script that loops over some files, plotting them > individually with imshow().
