error with text object properties using matplotlib 0.98.1

_David_M_Kaplan1 · July 10, 2008, 3:15pm

Hi,

I just upgraded to matplotlib 0.98.1 on a ubuntu hardy heron system. I
have noticed two problems since the upgrade:

1) For any plot, if I try to look at the properties of a text object I
get an error related to FontProperties having no attribute 'items'. See
below:

In [1]: plot(range(10))
Out[1]: [<matplotlib.lines.Line2D object at 0x924f9ac>]

In [2]: xlh=get(gca(),'xticklabels')

In [3]: get(xlh[0])

collapse_curves.adult_cubic.frac_crit_0.50.eps (94.2 KB)

    for key, val in d.items():

2) I have noticed that the font used for the xticklabels and the font
used for the xlabel and contour labels appears to be different (example
attached). One appears to be serif and the other sans-serif. This
seems to be due to using tex for text rendering. I am not sure if this
also occurred before the update, but I didn't notice it previously.
Looking at the properties of the different text objects, it isn't
apparent that there should be a difference - both have font properties
that indicate sans-serif, but the text of tick labels appears to be
surrounded by $'s forcing it through the text parser, while that of the
contour labels is not. Is this difference normal or expected? Is there
a way around this? In particular, I would like to use sans-serif for
everything - is this possible while still using tex?

Thanks for the assistance.

Cheers,
David

Thanks for the report. This is a bug and should now be fixed in SVN.

a way around this? In particular, I would like to use sans-serif for

To clarify -- you've set the rcParam "text.usetex" to True?

If the tick labels are in fact surrounded by $'s, then, yes, TeX will render then in a serif font. This is the default behavior of TeX (math is in a serif font) -- though there might be a special package you could add to the preamble (the rcParam text.latex.preamble) to change this, but that's more of a (La)TeX issue.

Looking at the revision history, it looks like putting $'s around tick labels has been done since at least 0.90.1.

Perhaps one of the usetex developers/users has more insight into this than I do.

Mike

It has always been this way. We tried a workaround once a couple years back
and it turned into a real mess.

I think there is a package, sansmath or something like that, that will allow
latex to use sans-serif fonts in math mode. You could try adding it to the
text.latex.preamble rc setting, but that option is not officially supported.

If you don't like the limitations of latex, you might want to turning off
usetex and just use matplotlibs mathtext, which recently got a significant
rewrite and is now quite capable thanks to Mike Droettboom. Here's some
documentation too:

Hi,

Thanks for the suggestions. I have stopped using the usetex option. To
make math and normal text match, I tried the following:

rcParams['font.family'] = 'serif'
rcParams['mathtext.fontset'] = 'stix'

This didn't make them match - normal text looked to me like it was still
sans-serif, while mathtext was with serif. Is there something else I
should be doing to make this happen?

Thanks again for your help.

This works for me. Could you set the rcParam verbose.level to debug-annoying and send the output -- that will print some information about where it's looking for fonts and what it can and can not find.

Hi,

The output from using debug-annoying is attached. It all looks
relatively normal to me, but perhaps you will see something I don't. I
am thinking that the problem is the difference between Bitstream Serif
and the STIX fonts - they are just different. Perhaps you can suggest a
way to change say the fontfamilies that will make them agree.

Thanks,
David

I thought you said the normal text looked sans-serif. The debugging output seems to suggest otherwise. Maybe you can send me the generated plot as well.

The default serif font, Bitstream Vera Serif, is not an identical match to the STIX fonts. The STIX fonts are designed to match Times. If you have Times (or Times New Roman) installed on your system you can set "font.serif" to "Times" in your matplotlibrc. That may help the fonts match better.

Cheers,
Mike

Hi,

I guess the problem was mostly mine. To my eyes, the Bitstream Vera
Serif doesn't look very "serif" to me (figure attached), but I am
probably just not used to that font. Changing font.serif as suggested
produced much more similar output. Thanks and sorry for the unnecessary
confusion.

However, this brought me to another strange problem. When I added a
matplotlibrc file to ~/.matplotlib/ and ran ipython -pylab, none of my
graphic screens appear (i.e., figure() produces no visible window).
Plotting works and I can save figures, but they just are not visible.
It makes no difference what is in the matplotlibrc, an empty file
produces the same result as a file with directives in it. Removing
matplotlibrc allows me to see the plot window. Does this make any
sense?

Just in case it matters, I am currently using the svn trunk of
matplotlib.

Cheers,
David

I thought you said the normal text looked sans-serif. The debugging
output seems to suggest otherwise. Maybe you can send me the generated
plot as well.

The default serif font, Bitstream Vera Serif, is not an identical match
to the STIX fonts. The STIX fonts are designed to match Times. If you
have Times (or Times New Roman) installed on your system you can set
"font.serif" to "Times" in your matplotlibrc. That may help the fonts
match better.

Agg appears to be your default backend. You can set a GUI backend in your
matplotlibrc and then you will get your windows back.

Hi,

I guess the problem was mostly mine. To my eyes, the Bitstream Vera
Serif doesn't look very "serif" to me (figure attached), but I am
probably just not used to that font. Changing font.serif as suggested
produced much more similar output. Thanks and sorry for the unnecessary
confusion.
