matplotlib-users Mailing List for matplotlib

We used to explicitly remove the link when we used mingw for the
python2.4 build. The VS build didn't seem to suffer from the problem,
but not these reports are coming up. I might try removing the link
again. Otherwise I will look into including it.

Hello.
I have got this error on a very clean installation of Windows 98SE and
matplotlib 0.87.4 / numpy 0.9.8 / official python 2.4.
>>> from pylab import *
The import of the numpy version of the _transforms module,
_ns_transforms, failed. This is is either because numpy was
unavailable when matplotlib was compiled, because a dependency of
_ns_transforms could not be satisfied, or because the build flag for
this module was turned off in setup.py. If it appears that
_ns_transforms was not built, make sure you have a working copy of
numpy and then re-install matplotlib. Otherwise, the following
traceback gives more details:

(free translation -> DLL load failed: Couldn't find one of the files of the
library needed to run this program)
I have searched for it and found this post
http://mail.enthought.com/pipermail/enthought-dev/2006-May/001597.html, tha=
t
seems so much like my problem, except that it is using Numeric not numpy.
Also, i found this post
http://www.mail-archive.com/mat...@li.../msg00502=
.htmlthat
could be related to my problem.
So, I decided to pull this DLL from the web and throw at C:\Windows\System.
Then, everything worked fine.
This confirms Christopher Barker suspicions (
http://www.mail-archive.com/mat...@li.../msg00523=
.html)
that it is a DLL not shipped with stock Windows but some other program
would install it (that is what nobody complained about the missing DLL).
I think matplotlib should ship this DLL, as a lot of other programs do...

Hi,
 When matplotlib is used interactively, eg, with ipython, I find 
that it will be convenient if I can copy the graph into clipboard and 
then paste it to other program. But this feature is missed in current 
release. Is there a plan to add this functionality in a future release? 
If possible, adding a print/preview button will be useful too.
Many thanks for developers' great work.
