[Matplotlib-users] xlabels / ylabels as (non-math) text for pstoedit
Hey everyone,
this is more a how-to / feature request than a question... Normally, my
workflow for embedding images in LaTeX is as follows:
1) produce ps-file
2) use pstoedit (xfig) to separate text/math (LaTeX-typesettable) from
the image
3) save as pdf_t and pdf, respectively
4) \input this in the LaTeX document -- pdflatex will then set the text
at every compilation.
This has the advantage that I can change fonts etc without having to
redo all the figures.
I was trying to do so with matplotlib 0.98.3 and pstoedit 3.45 on a
64bit Ubuntu 8.10. I followed the instructions in the matplotlib
cookbook but kept experiencing problems when calling pstoedit [1], the
xlabels and ylabels were somehow converted to Courier but not put in the
text part, . would become : and so on.
Solution brought this thread
http://www.nabble.com/Switching-between-different-font-settings-ts21279388.html
which suggested using OldScalarFormatter (thanks at this point also from
my side, Jouni) -- which works, see attached example.
So much for the how-to-part -- obviously, my suggestion is now to not
force users to have math-labels. I have to admit that I am not aware of
the drawbacks of OldScalarFormatter, but alone the name makes me think
that it might be not the best solution...
Thanks and best regards,
Sebastian.
P.S.: why actually does
ax.yaxis.get_ticklabels()[1].get_text()
return an empty string when called before savefig?
P.P.S.: I expect to be offline several days, so please excuse me if I
won't be answering timely.

[Matplotlib-users] changing matplotlib fonts in illustrator
hello all, I make my figures in matplotlib and then output them (using savefig) as .pdf. I am using Fedora linux. When I try to edit the font in the figure to Helvetica using Illustrator, I cannot. i am able to select the fonts, e.g. labels on the axes of the figure, but when i try to change the font it does not work. apparently the font information has been lost. is there a way to make the .pdf file contain the font? or is the solution to export it as a different file format (if so which)? p.s. i do not have helvetica on the system that generates the plots so i cannot set it programmatically... this is why i export it using the default matplotlib font and then try to edit it in illustrator. thanks. -- Crystal Reports - New Free Runtime and 30 Day Trial Check out the new simplified licensing option that enables unlimited royalty-free distribution of the report engine for externally facing server and web deployment. http://p.sf.net/sfu/businessobjects___ Matplotlib-users mailing list Matplotlib-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/matplotlib-users
Re: [Matplotlib-users] New contourf() drawing polygon boundaries for some reason?
On 06/12/2009 05:27 PM, Zane Selvans wrote: If I set path.simplify: False, the shape of the gaps between the filled polygons does change. Instead of being irregular, it becomes an infinitessimally thin gap of uniform width, allowing the (in this case white) background to show through. Just to clarify, these backs only show with the Mac OS-X gui window, not with the PNG or PDF output (which are actually handled by the Agg and PDF backends respectively, and don't use the Cocoa/Quartz-specific code in the macosx backend). If that's the case, I'll forward this thread to the attention of Michiel de Hoon, the author of the macosx backend. As for path.simplify = True causing irregular gaps, that's my area, and I'll look into that further. path.simplify should not be creating visible artifacts (at least in raster images such as PNG), so that's a bug. Cheers, Mike In both of these cases (path.simplify: True|False), the PNG version of the same figures also show representations of these gaps which are identical to those which appear in the PDF (though obviously pixelated), so I don't think it's something that's wrong in the vector graphics code per se.

There have been recent changes to that code. Also, since the Agg backend doesn't have an associated GUI, you need to use the savefig() command and provide a filename, rather than using show(). Cheers, Mike Zane Selvans wrote: Um, yeah. So my response got bounced because of the attachment. Take 2: For some reason my script bombed when I switched to the Agg backend, trying to display to the screen (it said Figure has no method show()) So I output the plot as both a PDF and a PNG (still having backend: agg in my rcfile) and in both of those cases, irregular gaps are visible between the polygons making up the filled contours. This wasn't the case with my previously installed setup. It looks as if for some reason the vertices of the filled polygons are being calculated differently from different sides of the same contour, leading to overlap in some places, and gaps in others. You can download the PDF version (in which the exact geometry is much clearer). from: http://zaneselvans.org/dropbox/LinDensity_Grid.pdf Zane On Fri, Jun 12, 2009 at 5:51 AM, Michael Droettboommd...@stsci.edu wrote: So you see this behavior if you switch to the Agg backend? That's the backend used to generate the images in the gallery. If there's a difference there, that would seem to suggest some tweaking of the macosx backend (which is still relatively new) is in order. Mike Zane Selvans wrote: I just installed the latest SciPy Superpack in order to get access to the scipy.spatial.KDTree class, and discovered that for some reason now when I use contourf() lines get drawn at the boundaries between the filled contours. Additionally, there is always a single vertical line crossing from each contour boundary to the next. I'm guessing that these are the edges of the filled polygons which are getting drawn. This behavior doesn't seem to be consistent with the contourf() documentation and when I run code in griddata_demo.py it doesn't come out looking like the picture in the documentation/example gallery... Is anyone else seeing this behavior? Is there a keyword I can use to force the edges of the polygons not to get drawn?

Re: [Matplotlib-users] changing matplotlib fonts in illustrator
You might want to try setting the rcParam pdf.fonttype to 42 (i.e. TrueType mode), which will avoid font subsetting. You may also want to try using the Ps backend, which does support Helvetica directly. matplotlib ships all of the standard Ps font metrics as part of matplotlib. Be sure to set ps.useafm to True.
