matplotlib-users Mailing List for matplotlib

hello,
I'm trying to import matplotlib.backends but I get a message indicating that matplotlib has no module 'backends'. So I looked to confirm that it was there and it is. I also checked if other modules where available (by importing them from the command line) and it appears that all the module are available but NOT any of the packages located in the matplotlib installation folder.
 
I just downloaded the latest matplotlib and installed it on a brand new machine that is running vista. I'm running python 2.6.
 
how do I fix this problem?
 
thanks,
Jeff

They are all reasonable. There are lots of different ways of handling this case. 
 From the R documentation:

Now there are 3 different 75 percentiles :). Any ideas, which is one the
most correct?

I have used matplotlib's percentile outputs on some of my abstracts and
posters, not yet in a paper. Not a big difference amongst them, but still
makes me think, should I compare similar other function results with other
programs when I do data analyses.

If mlab is supposed to be compatible with matlab, then isn't this a problem?

 From matlab, version 7.2.0.283 (R2006a)

 >> prctile([1 1 2 2 1 2 4 3 2 2 2 3 4 5 6 7 8 9 7 6 4 5 5],[0 25 50 75 
100])

ans =

    1.0000    2.0000    4.0000    5.7500    9.0000


Of course, the 75th percentile is different here too (5.75 instead of 
scipy's 5.5).  I don't know how to explain that discrepancy.

prctile does not handle the case where the exact percentile lies between two 
items. scoreatpercentile does.

You can see how matplotlib calculating percentiles. And yes it doesn't
conform with scipy's scoreatpercentile()


            # get median and quartiles
            q1, med, q3 = mlab.prctile(d,[25,50,75])

I[36]: q1
O[36]: 2.0

I[37]: med
O[37]: 4.0

I[38]: q3
O[38]: 6.0


Could this be due to a rounding? I don't know, but I am curious to hear the
explanations for this discrepancy.

I tried the following (most output text is deleted):

In [1]: ob1=[1,1,2,2,1,2,4,3,2,2,2,3,4,5,6,7,8,9,7,6,4,5,5]
In [2]: import matplotlib.pyplot as 
plt                                       
In [3]: 
plt.figure()                                                          
In [4]: 
plt.boxplot(ob1)                                                      
In [5]: 
plt.savefig('test.png')                                               
In [6]: import 
scipy.stats                                                    
In [7]: 
scipy.stats.scoreatpercentile(ob1,75)                                 
Out[7]: 5.5


Note that the 75th percentile is 5.5.  R agrees with this calculation.  
However, in the boxplot, the top of the box is around 6, not 5.5.  Isn't 
the top of the box supposed to be at the 75th percentile?

Thanks,

Hello,

I have two figures, one with mpl's mathtext and the other one with the latex
as seen on the uploaded images:

http://img10.imageshack.us/img10/9384/mathtext.png

http://img188.imageshack.us/img188/5128/usetex.png


1-) How can I use the same fonts of mathtext figure (tick and label texts)
on the latex one?

2-) When I use mathtext, I always get an extra space after the math term (in
my case, after mm^-1). This doesn't happen when I use latex however I do not
know how to use same font for both ticks, labels and equations.

3-) Both in mathtext and latex mode, if the term I use cannot be parsed
correctly I get a super long error notifications. Couldn't this be made
friendlier?

Any solutions or suggestions?

Thanks,

OK, I will build the final 0.99.1 installers with the
--user-access-control=auto option (works on Python 2.6+).

Christoph, can you take a look at this?

This is not expected to be fixed until matplotlib 1.0.  The changes
required to fix this are too pervasive for the 0.99 release branch,
where the emphasis is on stability.

Just installed it on Vista and saw the following issues so far.

- Installer is not running elevated - tracker item 2858636 added
- the issue with __doc__ handling in e.g. mlab.py is still present, see

We are preparing a bugfix release of the 0.99 branch, and a release
candidate 0.99.1rc1 is available for testing.

  http://drop.io/xortel1#

Please post any problems you find on the bug tracker

  http://sourceforge.net/tracker/?group_id=80706&atid=560720

and any patches on the patches tracker.

  http://sourceforge.net/tracker/?group_id=80706&atid=560722

It will help if you also ping the mailing list since not all the
developers check the tracker as regularly as the lists.

The bugfixes from the svn commit log since 0.99.0 are included below:

fix legend bug ignoring CircleCollection

This is usually caused by a mismatch in the Unicode mode of the python 
interpreter and the extension module.

Python can be built to use either 2-byte or 4-byte Unicode code points.  
If you build an extension on a Python interpreter that uses one, but use 
it on another, this error is the most common result.

Did you build basemap using the same Python interpreter that you are 
using to run it?

Cheers,
Mike

That *is* strange.  I'm at a bit of a loss.  Is it segfaulting?  Can you 
get a traceback from gdb?

Since I'm having no trouble with the FC11 packages, that suggests it's 
something related to a difference in configuration.  Are you doing 
anything unusual with fontconfig?  Are you 64-bit or 32-bit (I'm on 
32-bit, for what it's worth)?  Are you running the freetype or 
freetype-freeworld package?

What does:

fc-list "Computer Modern"

display?

Sorry for all the questions, but I'm grasping for something here ;)

Cheers,
Mike

Hi,
I have a strange problem with matplotlib: I use the greek character phi as a
label ($\phi$). When I display the diagram everything looks fine, only when
I save to an eps file, the phi dissappears (emplty space instead). Some
other characters (\mu, \Delta) don't have this problem. Does anyone have an
idea what the problem could be?
Cheers,
Diaboflo
