matplotlib-users Mailing List for matplotlib (Page 8)

Ah, sorry about that. In the script I was using it had the closing $. In spite of the typo, Gary Ruben found the actual bug: math mode doesn't support --. 

Thanks,
Sean

that also doesn't work.  The following would work (this is a LaTeX thing - not matplotlib)

r"80--120"
r"$80\textrm{--}120$"

Um, how about r"$80--120$" instead of r"$80--120" ?

Hi Sean,

I just checked - the hyphenation you want does not work in LaTeX in math mode.  Try removing the "$"-signs in your string command.  Then the hyphenation should work.

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--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.

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.

Alejandro.

(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!!

Hi:

I am trying to use this code http://tinyurl.com/44zcpfk (Scipy
cookbook) to make an animation where the background is fix and only a
line is updated. However, after executing the code, I only get a
window with an empty plot. Some debugging shows that the update_line
function is not being called.

I changed the use of numerix by numpy with respect to the original
code. Other than that is the same.

Any advice on how to fix the problem? Or may be this way is obsolete,
but all the animation examples I've found so far don't consider a
fixed background.

Alejandro.

Sorry for another email,

Please all ignore my previous emails, I have figured it out and it was a
stupid error on my part plotting time rather than time[0] etc.

Apologies and best wishes,

Libby

Hello,

I've been playing with the script and I now know a little bit more about
what is wrong. I can get the full graph space to plot by changing:

ax_mass = SubplotHost(fig, 1,1,1, aspect=1.)
to
ax_mass = SubplotHost(fig, 1,1,1)

but then a line is never drawn. I have removed the x and y axis limits and
it plots the axes for the limits of the date but no line for the graph? Here
is the relevant part of the code:

fig = plt.figure()
ax_mass = SubplotHost(fig, 1,1,1)

frac_to_mass = gasmass
print 'frac_to_mass', frac_to_mass
aux_trans = mtransforms.Affine2D().scale(1., frac_to_mass)
ax_frac = ax_mass.twin(aux_trans)
ax_frac.set_viewlim_mode("transform")

fig.add_subplot(ax_mass)
ax_mass.plot(time,massesMsun, linestyle='-', color='k', linewidth=2.0)

ax_mass.axis["bottom"].set_label("Time (Myrs)" )
ax_frac.axis["right"].set_label("Fraction of Original Gas Mass in Stars" )
ax_mass.axis["left"].set_label("Mass in Stars (Msun)" )
ax_frac.axis["right"].major_ticklabels.set_visible(True)
ax_frac.axis["top"].major_ticklabels.set_visible(False)
plt.savefig(frame_template %(folder,name[0],name[int(sys.argv[1])-1]),
format="eps")


can I not use ax_mass.plot?

Thanks,

Libby

Hi,

Fixed it by deleting fontList.cache in my tmp directory that was being used
by the web server.

Maybe this helps someone else.

When run as the web server, it's probably running as a different user.  
Is Arial installed in ~/.fonts?  If so the webserver user won't find it.

You can set "verbose.level" to "debug-annoying" in your matplotlibrc.  
If the webserver is collecting standard output, the debug messages 
should end up in the web server logs.

Hi all,

I'm trying to use matplotlib to generate some graphs on a webpage for me.
 Everything works pretty well, except, I cannot make a change to the fonts.
 I've set up the scripts to be called as a cgi script or to be run from the
command line.  When I run them from the command line, I get the correct font
(Arial) yet when run from the web page, it uses the CMR10 font.  Arial is
installed on the linux system.

I've thought the problem might be related to which matplotlibrc file each
script might be using, but when I check matplotlib.matplotlib_fname() from
the command line and web page, they return the same.

Maybe there is a way to get the --verbose-debug output when run from a web
page?  That could help me figure out what's going on.

I know I could manually specify the font using font_manager, but that's not
really ideal as I'd have to do it manually for each graph.  I'd rather have
a global solution for all my graphs.  Any help is greatly appreciated.

I don't see a good reason why this was not done.  (Maybe someone else 
has the historical context, if any).

Would you mind adding an issue to the tracker for this?

I don't use 'draw()'

Hello.

I want to plot the result of a calculation, show it, modify and
repeat. I have tried with pyplot interactive mode, see code:
http://pastebin.com/jsdsLN4z

The first plot shows fine, but from now on, all the new plots appear
in a new window and all of them are blank --including the first one! I
guess I am missing something. What could it be?

I am using Matplotlib 1.0.1 on Python2.5 and Windows XP.


Thanks,

David.

This bug or feature? is still in matplotlib 0.99.1.1 (Ubuntu 10.04 LTS)

More precisely scatter using symbols with zero area ('x', '+') will not
pick, regardless of the float value in picker.
Although this DOES work with plot, you can't vary the marker size between
points like you can with scatter.
I have also confirmed this in a version of the example in the docs
http://matplotlib.sourceforge.net/users/event_handling.html#picking-exercise
Which I could upload, but the code below is just fine.

If this is a feature, I suggest it be stated in the documentation.

Straightfoward solution is to deselect zoom or pan by clicking those buttons
again.  The cursor returns to the "Arrow" shape.
Any better solution?

I would like to put a gtk.Button on top of a FigureCanvas. But whatever
I try the FigureCanvas stays always on top hiding the button.

Below is an example where I can change the order of buttons
by switching the following two lines

   lay.put(but1,360,260)
   lay.put(but2,360,275)

but this doesn't work for FigureCanvas

  lay.put(canvas,0,0)

Any help appreciated.

Ciao
Andreas
