[Matplotlib-users] Fail to try api example code 'watermark_image.py'

[Thore O. <tho...@is...>]

Dear Developers of Matplotlib,

at first thanks for this mightiest tool for graphical output from python 
data. I have encountered problems on trying the watermark feature as 
described at 
http://matplotlib.sourceforge.net/examples/api/watermark_image.html.

When I invoke the script from a Enthought Python Compiler in the Windows 
COM then I got this message:

Traceback (most recent call last):
   File "Fluide\script1.py", line 13, in <module>
     datafile = cbook.get_sample_data('logo.png', asfileobj=False)
   File 
"D:\Programme\Enthought\lib\site-packages\matplotlib-1.0.1_r0-py2.6-win32.egg\matplotlib\cbook.py", 
line 676, in get_sample_data
     return myserver.get_sample_data(fname, asfileobj=asfileobj)
   File 
"D:\Programme\Enthought\lib\site-packages\matplotlib-1.0.1_r0-py2.6-win32.egg\matplotlib\cbook.py", 
line 623, in get_sample_data
     raise KeyError(msg)
KeyError: 'file iselogo.png not in cache; received <urlopen error [Errno 
10061] No connection could be made because the target machine actively 
refused it> when trying to retrieve'

Does anyone no a solution for this problem?
Thanks in advance for your help.

Kindly regards,
