matplotlib-users Mailing List for matplotlib

Hello all,
I'm trying to specify a range of numbers in a particular legend using LaTeX. In order to do so I'm feeding it the string: r"80ドル--120". The output should be have an endash, "80–120", but I'm getting "80--120". This is a standard feature of LaTeX ( http://en.wikibooks.org/wiki/LaTeX/Formatting ), so I don't know what's going on. 
Thanks,
Sean Lake

I think you may have to do something like "label=r'\textbf{label1}'".

Hello,
I am using pylab with the rc parameter
rcParams['text.usetex']=True
Now, I would like to make a legend with bold fonts.
So, I tried two options:
1)
from matplotlib.font_manager import fontManager, FontProperties
font= FontProperties(weight='bold',size=26)
plot([1,2,3],[1,2,3],'k',label='label1')
legend(loc='lower left', prop=font)
2) After the legend(loc='lower left', prop=font) statement, I put:
legend1=gca().get_legend()
ltext = legend1.get_texts() # all the text.Text instance in the legend
setp(ltext, fontweight='bold') # the legend text fontsize
Neither of these options changed the legend font weight to bold.
How can this be done?
How to change the legend font weight when rcParams['text.usetex']=True ?
Thanks,
Eli

I also needed to use Frank's approach (described in the link above) to
make my animation works. Is it possible to fix the code in the
cookbook? I tried to edit the page but I am not allowed.

Adding
import matplotlib
matplotlib.use('GTKAgg')
solved the problem.
But now I get this warning:
/usr/lib/pymodules/python2.6/matplotlib/backends/backend_gtk.py:621:
DeprecationWarning: Use the new widget gtk.Tooltip
 self.tooltips = gtk.Tooltips()
I am running Ubuntu 10.04, with MPL version 0.99.1.2-3ubuntu1, in case
that matter.

(sorry if this is the wrong place, I'm just trying to help)
In the documentation FAQ 
http://matplotlib.sourceforge.net/faq/installing_faq.html#what-is-a-backend
the link to "antigrain" is broken.
Additionally, to whom it may concern, thanks for Matplotlib and Pylab, 
it's wonderful software and I use it nearly every day!!
