Probably you need a unicode font-set that contain all the characters for
those alphabets. You can look at this example to see a simple unicode
demonstration example.
http://matplotlib.sourceforge.net/examples/pylab_examples/unicode_demo.html
Make sure you are using the right font in your matplotlib.

You have to adjust your label to get it seen. You may try with:
xlab = plt.xlabel("my x-axes label")
xlab.set_position((0.2, 0.1))

Two ways I can think of are: annotate and text functions of pyplot api.

Let me know if these work fine for you.

Hi,
I would like to create 3D plots. A search revealed the following page:
http://www.scipy.org/Cookbook/Matplotlib/mplot3D
which explains to install matplotlib version 0.99 to use the 3D code.
Unfortunately, after installingmatplotlib-0.99.1.1 (from
matplotlib-0.99.1.2.tar.gz) I am not able to use the 3D code. The
command that show that the correct version is used together with the
error is shown below.
Any idea how I can use this code? Do I have to downgrade to the 0.91.x
maintenance branch? Or do you suggest to use mayavi
(http://code.enthought.com/projects/mayavi/docs/development/html/mayavi/mlab.html)?
I also tried to install the latter, after 1 hour of installing code
and requirements and cmake and easyinstall.. I got the error that VTK
is not installed. So: Any idea how to create a simple 3D scatter plot,
seen from any arbitrary angle?
Thanks
 Alex

Hello everyone,
I hope you can help me with two problems I am struggling with. The 
second question, I imagine, should be rather easy, but I wasn't able to 
figure it out by googling.
a) My graph will have Chinese labels, however mpl does not render the 
Chinese characters. I was unable to find how to teach it some CJK. Could 
you please indicate what the approach to be followed is?
Also, the xlabel is not shown when sizing/saving the graph at (3.6, 
2.22) inches. Why is that? And how can I make mpl show the xlabel?
b) In the file dea.png (attached) you can see that data points are 
rendered by points ('ko'). Each of these points has an associated name; 
for example, point (1,4) is 'A'. This name, 'A', should be incorporated 
into the graph so as to identify the point. 'A' should be placed right 
next to the dot. Could you please let me know what the easiest way is to 
solve this problem?
Thank you very much for your help!
David

Hi all...
On this afternoon I installed on my ubuntu 8.04 server the python-matplotlib
package and his dependencies.
but If I pay attention right that package installed matplotlib 0.91
on my local desktop wich run windows, I installed the last version...
Anyone knows how do I de-install only matplotlib pack, let only the
dependancies
and install the most recent version?
thanks in advanced...
Samuel

Thanks! :D 
Thank you very much. The ipython -pylab is working great! 
Tomislav
P.S.
Enjoy the Hawaiian sunshine... :D I'm freezing in Munich, Germany...

This is a common "gotcha": don't use pyplot.show() anywhere other than 
at the end of a script, and then only when you want the script to 
display a figure and block. For working interactively with ipython 
(which it appears you are doing, and which is recommended), use "ipython 
-pylab". Then, the figure will be redrawn automatically after pyplot 
functions are called. If you use a more OO approach, say using the 
Axes.plot(...) method rather than the pyplot.plot(...) function, you can 
use pyplot.draw() to force an update when you want one.

Ian,
As the person who fixed major bugs in cntr.c, you have wizard status, so 
go ahead! I have no objection to some refactoring, so long as 
everything works in the end, and is no more difficult to read and 
maintain than what is there now--which I am sure could be improved even 
without the Tri additions.
What sort of timeline do you have in mind?
One possibility would be to develop the tri* functionality at least 
initially as a module in lib/mpl_toolkits, like axes_grid and mplot3d; 
or in a module in lib/matplotlib. This could still take advantage of 
refactoring in contour.py. An advantage is that it would consolidate 
the triangle functionality so it would be easier to find, track, and 
document.
I copied this reply to the devel list--let's continue there as needed.

Hi, 
I forgot to write something in my last email: I just wish to thank the developers of this insanely
great tool. Long live open source. Thank you very much for this, it's the best data/graph manipulation 
software ever.
Now, for my question: I'm not sure if I misunderstood something, or is it a bug of some sort. 
Here is the code with the error:
http://pastebin.com/3QUws70n
I don't understand, why would a figure object get deleted after it's shown on the screen? What am I doing wrong?
Thanks in advance,
Tomislav

Thanks a lot! This worked like a charm. I'll need to dig into matplotlib a lot later, 
but now I have truckloads of bugs in my code to deal with, this will speed me up
significantly.
Thank you again,
Tomislav

Hello everyone, 
I'm using matplotlib for plotting data results from numerical simulations that involve a lot of geometric calculations. 
I did read the tutorial, but I haven't been able to figure out the proper way to set the axis aspect ratio to "1" when

I've loaded the data using pylab.load and I've plotted the files without using figure or axes, just plain old

It was just a guess, as I noticed that the other call to FT2Font is 
using str too.

Yeap, I see this now too.

It should be there, i.e. mpl-data in the lib/site-packages/matplotlib 
folder has the same number of files and folders as the one created by 
setup.py in dist.
But it obviously doesn't find it or some other setting to handle the 
LaTex stuff is not there.
Put this at the top of alphabeta.py, i.e. just after import matplotlib
matplotlib.verbose.level = u'debug'
and change setup.py to generate a console app. If I run this on my dev 
machine the output shows that fonts are found, but if I run it on the 
py2exe'd version lots of STIX fonts are not found. Even so these fonts 
are in mpl-data/fonts/ttf of the py2exe dist folder.
So, I think/guess that the font searching is not done correctly, as 
running with verbose "debug" it shows that it finds the mpl-data folder 
in the dist folder or wherever you copy dist too.
Hopefully someone who knows how the font searching is done can help 
out/point to the culprit.

Hello,
This is usually done by using several calls to "axes", specifying the 
coordinates of the different plots in the figure.
The "plot" coordinates are in the range 0..1 times 0..1.
An example is provided here
http://matplotlib.sourceforge.net/examples/pylab_examples/axes_demo.html
with two plots in the main one, you can skip one of them.

Changing the line 560 in mathtext.py from:
 font = FT2Font(basename)
to:
 font = FT2Font(str(basename))
Fixed it for me, I don't know what FT2Font does and why this matters - 
hopefully someone else can expand on this.
Attached your setup.py a bit simplified as you are using matplotlib 0.99.

Hi everyone,
I've been trying (with no luck) to add a plot inside a plot, like this
(apologies for the ascii art), the smaller box represents the plot I
want to add. The thing I know it doesnt want to be a subplot and I
can't find an example of this plot in the gallery. It is possible in R
with some hacking....and I'm hoping its possible in matplotlib.

Any ideas on how to do this? I m guessing/hoping someone must have
done it before?
Many thanks in advance

I'll post to matplotlib-devel shortly and see what response I get.

Yes, it is C++ and it is important - that's what I've got and hence
that's what I'm offering! Portability should be fine as I'm only
using some of the basic STL containers which are already used by, for
example, the matplotlib delaunay code.
