Yes, because dvipng - version works fine.

If you're fortunate enough to be using the wx backend, there is a
Copy_to_Clipboard() method which works great: In a wx App, Ctrl-C can
easily be bound to copy the figure to the clipboard, then paste it
into apps such as Word. I tend to find better results from saving a
higher-resolution PNG and inserting that into documents, but this
copy-and-paste works great for quick prints (whereas printing directly
from a wxApp seems to be very fragile and change with every wxPython
release)
I think pylab may not give you access to the Copy_to_Clipboard() method.

changing the font family works for me. Maybe you should try deleting 
your .matplotlib/tex.cache and trying again.

Is dvipng on your path?

Hi all,
I'm running matplotlib on Mac OS X and I've set text.usetex to True in
matplotlibrc, but if I try to run the tex_demo I get the error shown
below. If I'm right it's a problem with dvipng:

Did you install pstoedit? If you do, you'll see that inkscape will
then be able to load .eps/.ps files in a fully editable format. I've
used it to fix decade-old plots for which the only thing around was
the eps file.

Glad it helped.

Sorry. Just discover that saving the file in emf format under Inkscape and then import into Word works even better. The eps engine in Word is really bad.
Hope that this info is helpful to others who are stuck in an Office world like me.

This is simply too good to be true. I played with manupulating MPL plots using Inkscape and man, somebody ought to include this in the MPL FAQ. I can move everything around by elements, touch-up or remove things I don't want, scale it, rotate it, you name it.
And then I can save the file in .eps and include into Office - and I don't loose any quality.
Perfect!
Here's what I learned:
a) Create the plot under MPL, saving the file in .svg format, and use the figsize argument to figure to create a plot of the proper size
b) Use Inkscape to open the .svg file and manupulate it. Save in .eps format.
c) Import the .eps file into Office.
d) Be happy and become famous and rich. (not)
Thanks again for all of the suggestions and tips.

Actually, Gimp is the problem. It's obvious they don't have a very good rendering engine. The plots looks very good under Inkscape.

Most likely Word. It's very picky. I have .eps files created by other programs where Word would simply tell you that it's not a supported format. Doesn't say why.

hmm. I wonder what it is about MPL's .eps files that Word doesn't like.
Bug in MPL or Word??

Yes, that's what I've been forced to do. The problem with that is that it forces you to fix the size of the figures in your paper. When I reformat things around in subsequent revisions, I have to go back and recreate the figures - if the spacing changes. I would much rather retaining the ability to rescale in Word. Yes, I know that it does change the font size.
But as I indicated in my other message, I think Inkscape is the solution. I am still playing around with it and see if that really does it but it looks real promising.

Subject: Re: 
[Matplotlib-users] SVG vs PNG
My advice would be to define 
the size you'll want the figure to be on paper once printed, and set the 
resolution to 300 dpi (for paper) or 100 (for 
screen):
e.g.
fig.savefig(figsize=(8,8), dpi=300)
Rescaling the 
figure is generally a bad idea for inclusion in a paper since it changes the 
font size as well. To get a nice output, you try to keep the same font size for 
both paper and figures, and the simplest was to do this is by avoiding 
rescaling. 
Cheers, 
David

Correct. I am doing that right now. However, 
because it's not vector based, if I start chaning the figure size, the quality

Bingo! My prayer appears to have been answered.
inkscape has no trouble reading the .svg files created by MPL, and Word has no trouble reading the .eps files created by inkscape. So, at least I can use it to preserve the vectors. Too bad inkscape doesn't read .eps directly (complaining...complaining....) :=)
inkscape treats everything as objects and allows you to ungroup the plots into elements and then you can play with each of the elements individually. When I am done, I can then insert into Word. Too bad it doesn't allow me to paste the objects directly over to Windows but I am not complaining.
Thanks, Fernando.

John,
thanks for your reply. Unfortunately it does not work for Axes (at
least for me).
I've got 3 axes (like the finance sample) and the ylabel appears only
for the last one and only if I use ylabel(...) (yes, I'm using
ax1.set_ylabel, ax2.set_yabel and ax3.set_ylabel)
Any idea?

The quality of the svg plot depends in large plot on the svg renderer
-- perhaps word doesn't do a good job rendering SVG? The matplotlib
PNG files look good because agg is a good rendering engine.

Perhaps you could use OpenOffice Draw as described in this url:

svg-wmf/
It's a shame that it takes such a workaround.

This part should be achievable with PNG.
Just set the figsize.

You can select part of a PDF for copying to the clipboard
in Acrobat.
fwiw,

Chris,
All I want is to:
a) Insert all of the plots I create with MPL onto a Word document. 
As I said before, my version of Word does not recognize the EPS or PS format created by MPL. I am not blaiming MPL. I am just not willing to send Redmond money to see if their later version does the job properly. The version of Word I have does not import PDF files neither. Besides, the PDF backend of MPL fails when the total number of figures is more then 8.
b) Be able to cut and paste part of a MPL figure and insert that to Word. I can do it now via the Gimp path but as I explained previously, the quality is not the greatest. I'll look up the cookbook you cited and try that.
Thanks,

Try inkscape. I've used it successfully for simple things, though
I've never tried to handle a MPL SVG file with it.

Strange. I have libfreetype.a in a staticlibs directory that I link to when
building these things. I will try again.

Thanks everybody for the explanation of svg in Gimp. That makes sense. Is there any vector based program that does what Gimp does?

Yes, I tried eps. Word won't recognize that neither.
As to the EMF format, I downloaded the package and attempted to apply the patch. Failed - probably because it's intended for 0.85 only. I am running 0.90 of MPL. Has anybody added EMF support to MPL 0.90 successfully?
