That's a font that probably came with a TeX distribution and somehow got
installed in your font library.

Failing on this line is a bug in matplotlib, since the AFM spec says
that bounding-box coordinates are "numbers", not "integers". Apparently
not many AFM files use that precise bounding boxes, since we haven't run
into this before.
I don't know how the MacPorts packaging system would react to modifying
installed files, but I imagine that applying the attached patch should
fix this.

Maybe the files just didn't get written into your directory, since
matplotlib bailed out at the first failure.

Could you do the following: (if you already exited that Python shell 
and can't reproduce the problem any longer, you can delete your
~/.matplotlib/fontList.cache and try again)
from pdb import pm
pm()
This should get you to a debugger. Then type:

to get some more information on what is going wrong.

Hi All,
After having installed Snow Leopard (10.6), I got some silly errors 
with libraries (installed via Macports) using deprecated functions 
Apple no longer supports, so I trashed the whole of Macports and 
reinstalled it. I then installed py25-matplotlib and get the following 
error message when trying the following

Maybe instead of using "import wxversion" (I think its intent is for 
developers having multiple versions installed) you might wnat to change 
the code in backend_wx.py to use one of the following:
import wx
 >>> wx.__version__
'2.8.10.1'
 >>> wx.version
<function version at 0x02BAEC30>
 >>> wx.version()
'2.8.10.1 (msw-unicode)'
 >>> wx.VERSION
(2, 8, 10, 1, '')
 >>> wx.VERSION_STRING
'2.8.10.1'
This way you don't use wxversion and the check will run in all situations.

Hi,
I have a few questions about the loglog plot :
1- Is there a way to a have axis format with real numbers rather than
numbers with exponent ?
2- I would like to have a grid not only for 10^2, 10^3, 10^4, 10^5 ... but
also for the minor axis ticks. is it possible ?
3- I use loglog to plot parallel lines. How can I have the function label
directly displaid next to the plotted straight lines ?
Thanks for your tips.

Nothing :D , I think this might be the culprit. However, I have
cm-unicode's ttf fonts installed:

Hi Jeff,
You don't happen to be in the same directory as a folder called 
'matplotlib' when trying to import matplotlib.backends, do you? If so, 
try moving to a different directory before invoking python and 
importing matplotlib.backends.

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.

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

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

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?

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

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,

- the issue with __doc__ handling in e.g. mlab.py is still present, see 
tracker item 2593149 and http://www.py2exe.org/index.cgi/MatPlotLib at 
the end of that page a work around is suggested
- backend_wx does a wxPython version check which does not work when the 
application is py2exe'd - tracker item 2858638 added and the above wiki 
page also contains a work around/correction suggestion.

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

Subject: [job] top-flight graphicist needed for climate science & media 
group
To: mat...@li... 
<mailto:mat...@li...>
Please apply if interested--or forward to any associates you believe 
would be good! Much appreciated; this is a very important position for 
us and we're looking for a real star. Many thanks--
Ben Strauss
Associate Director, Strategic Initiatives
Climate Central
 Seeking Immediately:
 Experienced Graphic Designer for Climate Science & Media Group's TV,
 Web Productions
 Objective
Climate Central seeks an experienced, inspired and technically 
proficient graphic designer or data visualization expert--ideally versed 
in both art and science--to develop conceptual and data-driven 
visualizations from climate science research for broadcast TV and 
Internet. A group of internationally recognized scientists and 
communicators, Climate Central is dedicated to producing vivid media 
based on sound climate change science, and has within its first 18 
months already appeared on PBS's The NewsHour with Jim Lehrer, 
nytimes.com <http://nytimes.com/>, bloomberg.com 
<http://bloomberg.com/>, TIME.com, Newsweek and Scientific American. We 
will begin this Princeton, NJ position as a 90-day contract; successful 
performance will lead to full-time hire.
 Description
Climate change presents one of the greatest communications challenges of 
all time. Many words have been printed, but Climate Central aims to 
develop an unmatched collection of clear, compelling, and science-based 
graphics and animations to tell the story visually. We are currently 
expanding capacity in this area.
The Designer will collaborate with staff scientists and producers, as 
well as design colleagues, to produce static graphics and end-to-end 
broadcast-quality animated visualizations tailored for a general 
audience. Each product must be accessible and understandable, yet vivid 
and scientifically rigorous.
The position will involve the development, maintenance, and application 
of a wide variety of tools for analyzing data and production, with some 
emphasis on tools for geographical display of information (GIS, Google 
Earth, Google Maps, generic maps). An important dimension of this 
position will be working with NASA scientists and satellite data to 
develop an Earth-from-space "sky witness" collection of climate change 
visualizations.
For a sample of Climate Central's designs and animations to date, see 
the static graphics and videos at climatecentral.org 
<http://climatecentral.org/>.
 Qualifications
Significant experience (5+ years best) in scripting, data conversion, 
modeling, rendering and compositing, and handling large datasets, is 
required. Candidate should show initiative and be a self-starter and 
self-teacher able to work well from high-level direction. We are 
looking for someone with commitment to excellence, attention to detail, 
and passion for work and the subject.
Applicants should be proficient with the following tools, languages and 
data formats we regularly use:
• Maya, After Effects, Illustrator, Photoshop, Google Earth/Maps
• Python, Javascript
• ESRI Shapefile, KML
...and it would also be helpful if you are familiar with:
• MATLAB/Octave, VTK, Blender, Imagemagick, Gimp, QGIS, GDAL/OGR, 
NCAR NCL
• C/C++
• NetCDF, CSV, HDF
 To Apply
To apply, please send a cover letter, resume and link to your portfolio. 
We are looking for thoughtful, personalized cover letters that 
demonstrate applicants' qualifications and work style. Send materials as 
text in the body of an email message to jo...@cl... 
<mailto:jo...@cl...>; please put "graphics" in the subject 
line. If you send attachments, they must be in pdf format.
No phone calls, please.
Salary is competitive and will depend on experience. Climate Central 
offers excellent benefits, a delightful workplace, and the opportunity 
to play a crucial role in an organization with a mission.
Climate Central is an equal-opportunity employer and does not 
discriminate based on anything except how good you are at your work. 
People of color and individuals from other underrepresented groups are 
strongly encouraged to apply.
 About Climate Central:
Climate Central combines sound science and vivid media to increase 
public understanding and attention to the climate challenge. In less 
than two years of operation, our work has already appeared on PBS 
NewsHour, nytimes.com <http://nytimes.com/>, bloomberg.com 
<http://bloomberg.com/>, time.com <http://time.com/>, newsweek.com 
<http://newsweek.com/>, Scientific American, and beyond. Our staff and 
board include internationally recognized climate scientists and 
communications experts. Visit our interim website climatecentral.org 
<http://climatecentral.org/> to learn more. Climate Central is a 501(c)3 
nonprofit organization.

I tried the code you supplied and I didn't get it to work with the *angles*
keyword, I got:
"ValueError: shape mismatch: objects cannot be broadcast to a single shape"
I have matplotlib.__version__ = '0.98.5.2'.
Although after thinking about it for a while I did:
from scipy import *
import matplotlib.pyplot as plt
X,Y = meshgrid(arange(64),arange(64)) # a bit bigger just to see what it
looks like
angles = arange(0,4*pi,4.*pi/X.size) # just creating a set of angles
u = cos(angles)
v = sin(angles)
c = arange(u.size) # the colours!
c.shape = X.shape
plt.quiver(X, Y, u, v, c, pivot='middle',minlength=0.04, width=0.05,
headwidth=1,scale=50)
that is, the angles are converted to "u" and "v" parameters.
Anyway. That is how I got it working.
