I am seeing the problem on python2.5 using the binary exe installer.
It appears we are getting fouled up by setuptools special handling of
the __init__.py file, which is supposed to be empty I think to support
namespace packages.  All the stuff we are defining in
matplotlib/__init__.py, like rcParams and friends, is being lost.
Instead, a

>>> import matplotlib
>>> dir(matplotlib)

just shows the special names '__path__', '__doc__',  and '__name__',
and the  'toolkit' dir.

Charlie, I don't know how you handled this last time, but is there
something in setuptools you have to disable for this build?

I gave it a try, and I did not get this error.

OK, I'm having a bad backend day (insert joke here).

Since I am on OSX, I decided to switch over to the CocoaAgg backend,
but it fails when trying to show a histogram, yielding the following

Hi,

After upgrading to the new matplotlib 0.9.1 on python2.4 using the 
windows binary installer I get the following error:


C:\>python

Does anyone else see the same thing?

Sorry for the confusion, I was still on the *old* problem of tkagg
hanging w/ hist, and was wondering if it was hanging with other plot
commands too.  Not that you can easily test now w/ the active tcl
install.

Thanks for the suggestion. I did do a fresh svn update and build after
installing Tk/Tcl.

Same thing. Here is what I did:

In [1]: from matplotlib import use

In [2]: use('TkAgg')

In [3]: from numpy import random

In [4]: x = random.gamma(0.1, 1000, 1000)

In [5]: from pylab import *

Possibly related to the _tkagg extension -- that's what defines the 
"PyAggImagePhoto" method.  If you installed ActiveState's Tcl/Tk after 
building matplotlib, that could explain this.  Try doing a clean build 
of matplotlib again (removing the build directory first).

But that's only a suggestion -- I don't use Macs much.

Cheers,
Mike

Is it only hist that is hanging?  Does plot work....  This one has me

JDH

A new release of matplotlib is posted to the sourceforge download site

http://sourceforge.net/project/showfiles.php?group_id=80706

You can read the release notes with links at
http://matplotlib.sourceforge.net/whats_new.html

enhanced mathtext - Complete revamp of matplotlib's internal math
layout and rendering engine. Michael Droetboom has improved the TeX
parser to significantly expand it's coverege, and implemeted Knuth's
box layout algorithms. Additionally, the much anticipated STIX fonts
for math expressions have come online and ship with matplotlib. See a
sample of the new mathtext at
http://matplotlib.sourceforge.net/screenshots.html#mathtext_examples

better configuration - Darren Dale has provided support for a site.cfg
configuration file to enable users and package maintainers to have
better control over the matplotlib build process. He has also provided
a (currently optional) enthought.traits enabled property configuration
to replace matplotlib's rc configuration using a maplotlib.conf file

writing to file-like objects - You can now pass file like objects (eg
StringIO) to all backends for hardcopy. This has been a much requested
feature for usage in web application servers.

record array support - New functions for loading, displaying and
saving numpy record arrays in matplotlib.mlab. See for example,
http://matplotlib.sourceforge.net/examples/loadrec.py

pyplot - Added a module matplotlib.pyplot which has all of pylab's
plotting functions (eg figure, plot, show, close) but does not import
the numpy namepace. This is useful for those who want to use the pylab
functionality w/o the namespace clutter.
http://matplotlib.sourceforge.net/matplotlib.pyplot.html

maskedarray - Added optional support for the scipy sandbox masked
array packaged. Configurable with an rc setting.

plotfile - Added new pylab/pyplot command plotfile for gnuplot style
file plotting
http://matplotlib.sourceforge.net/matplotlib.pyplot.html#-plotfile
http://matplotlib.sourceforge.net/examples/plotfile_demo.py

Here is the complete CHANGELOG

===============================================================
2007-11-27 Released 0.91.1 at revision 4517

===============================================================
2007-11-27 Released 0.91.0 at revision 4478

2007-11-13 All backends now support writing to a file-like object, not
	   just a regular file.  savefig() can be passed a file-like
	   object in place of a file path. - MGD

2007-11-13 Improved the default backend selection at build time:
           SVG -> Agg -> TkAgg -> WXAgg -> GTK -> GTKAgg. The last usable
           backend in this progression will be chosen in the default
           config file. If a backend is defined in setup.cfg, that will
           be the default backend - DSD

2007-11-13 Improved creation of default config files at build time for
           traited config package - DSD

2007-11-12 Exposed all the build options in setup.cfg. These options are
           read into a dict called "options" by setupext.py. Also, added
           "-mpl" tags to the version strings for packages provided by
           matplotlib. Versions provided by mpl will be identified and
           updated on subsequent installs - DSD

2007-11-12 Added support for STIX fonts.  A new rcParam,
	   mathtext.fontset, can be used to choose between:

	   'cm':
	     The TeX/LaTeX Computer Modern fonts

	   'stix':
	     The STIX fonts (see stixfonts.org)

	   'stixsans':
	     The STIX fonts, using sans-serif glyphs by default

	   'custom':
	     A generic Unicode font, in which case the mathtext font
	     must be specified using mathtext.bf, mathtext.it,
	     mathtext.sf etc.

	   Added a new example, stix_fonts_demo.py to show how to access
	   different fonts and unusual symbols.
	
           - MGD

2007-11-12 Options to disable building backend extension modules moved
           from setup.py to setup.cfg - DSD

2007-11-09 Applied Martin Teichmann's patch 1828813: a QPainter is used in
           paintEvent, which has to be destroyed using  the method end(). If
           matplotlib raises an exception before the call to end - and it
           does if you feed it with bad data - this method end() is never
           called and Qt4 will start spitting error messages

2007-11-09 Moved pyparsing back into matplotlib namespace. Don't use
           system pyparsing, API is too variable from one release
           to the next - DSD

2007-11-08 Made pylab use straight numpy instead of oldnumeric
           by default - EF

2007-11-08 Added additional record array utilites to mlab (rec2excel,
           rec2gtk, rec_join, rec_append_field, rec_drop_field) - JDH

2007-11-08 Updated pytz to version 2007g - DSD

2007-11-08 Updated pyparsing to version 1.4.8 - DSD

2007-11-08 Moved csv2rec to recutils and added other record array
           utilities - JDH

2007-11-08 If available, use existing pyparsing installation - DSD

2007-11-07 Removed old enthought.traits from lib/matplotlib, added
           Gael Varoquaux's enthought.traits-2.6b1, which is stripped
           of setuptools. The package is installed to site-packages
           if not already available - DSD

2007-11-05 Added easy access to minor tick properties; slight mod
           of patch by Pierre G-M - EF

2007-11-02 Commited Phil Thompson's patch 1599876, fixes to Qt4Agg
           backend and qt4 blitting demo - DSD

2007-11-02 Commited Phil Thompson's patch 1599876, fixes to Qt4Agg
           backend and qt4 blitting demo - DSD

2007-10-31 Made log color scale easier to use with contourf;
           automatic level generation now works. - EF

2007-10-24 Added ax kwarg to Figure.colorbar and pyplot.colorbar - EF

2007-10-19 Removed a gsave/grestore pair surrounding _draw_ps, which
           was causing a loss graphics state info (see "EPS output
           problem - scatter & edgecolors" on mpl-dev, 2007-10-29)
           - DSD

2007-10-15 Fixed a bug in patches.Ellipse that was broken for
           aspect='auto'.  Scale free ellipses now work properly for
           equal and auto on Agg and PS, and they fall back on a
           polygonal approximation for nonlinear transformations until
           we convince oursleves that the spline approximation holds
           for nonlinear transformations. Added
           unit/ellipse_compare.py to compare spline with vertex
           approx for both aspects. JDH

2007-10-05 remove generator expressions from texmanager and mpltraits.
           generator expressions are not supported by python-2.3 - DSD

2007-10-01 Made matplotlib.use() raise an exception if called after
           backends has been imported. - EF

2007-09-30 Modified update* methods of Bbox and Interval so they
           work with reversed axes.  Prior to this, trying to
           set the ticks on a reversed axis failed with an
           uninformative error message. - EF

2007-09-30 Applied patches to axes3d to fix index error problem - EF

2007-09-24 Applied Eike Welk's patch reported on mpl-dev on 2007-09-22
           Fixes a bug with multiple plot windows in the qt backend,
           ported the changes to backend_qt4 as well - DSD

2007-09-21 Changed cbook.reversed to yield the same result as the
           python reversed builtin - DSD

2007-09-13 The usetex support in the pdf backend is more usable now,
           so I am enabling it. - JKS

2007-09-12 Fixed a Axes.bar unit bug - JDH

2007-09-10 Made skiprows=1 the default on csv2rec - JDH

2007-09-09 Split out the plotting part of pylab and put it in
           pyplot.py; removed numerix from the remaining pylab.py,
           which imports everything from pyplot.py.  The intention
           is that apart from cleanups, the result of importing
           from pylab is nearly unchanged, but there is the
           new alternative of importing from pyplot to get
           the state-engine graphics without all the numeric
           functions.
           Numpified examples; deleted two that were obsolete;
           modified some to use pyplot. - EF

2007-09-08 Eliminated gd and paint backends - EF

2007-09-06 .bmp file format is now longer an alias for .raw

2007-09-07 Added clip path support to pdf backend. - JKS

2007-09-06 Fixed a bug in the embedding of Type 1 fonts in PDF.
           Now it doesn't crash Preview.app. - JKS

2007-09-06 Refactored image saving code so that all GUI backends can
           save most image types.  See FILETYPES for a matrix of
           backends and their supported file types.
           Backend canvases should no longer write their own print_figure()
           method -- instead they should write a print_xxx method for
           each filetype they can output and add an entry to their
           class-scoped filetypes dictionary. - MGD

2007-09-05 Fixed Qt version reporting in setupext.py - DSD

2007-09-04 Embedding Type 1 fonts in PDF, and thus usetex support
           via dviread, sort of works. To test, enable it by
           renaming _draw_tex to draw_tex. - JKS

2007-09-03 Added ability of errorbar show limits via caret or
           arrowhead ends on the bars; patch by Manual Metz. - EF

2007-09-03 Created type1font.py, added features to AFM and FT2Font
           (see API_CHANGES), started work on embedding Type 1 fonts
           in pdf files. - JKS

2007-09-02 Continued work on dviread.py. - JKS

2007-08-16 Added a set_extent method to AxesImage, allow data extent
           to be modified after initial call to imshow - DSD

2007-08-14 Fixed a bug in pyqt4 subplots-adjust. Thanks to
           Xavier Gnata for the report and suggested fix - DSD

2007-08-13 Use pickle to cache entire fontManager; change to using
            font_manager module-level function findfont wrapper for
            the fontManager.findfont method - EF

2007-08-11 Numpification and cleanup of mlab.py and some examples - EF

2007-08-06 Removed mathtext2

2007-07-31 Refactoring of distutils scripts.
           - Will not fail on the entire build if an optional Python
             package (e.g. Tkinter) is installed but its development
             headers are not (e.g. tk-devel).  Instead, it will
             continue to build all other extensions.
           - Provide an overview at the top of the output to display
             what dependencies and their versions were found, and (by
             extension) what will be built.
           - Use pkg-config, when available, to find freetype2, since
             this was broken on Mac OS-X when using MacPorts in a non-
             standard location.

2007-07-30 Reorganized configuration code to work with traited config
           objects. The new config system is located in the
           matplotlib.config package, but it is disabled by default.
           To enable it, set NEWCONFIG=True in matplotlib.__init__.py.
           The new configuration system will still use the old
           matplotlibrc files by default. To switch to the experimental,
           traited configuration, set USE_TRAITED_CONFIG=True in

2007-07-29 Changed default pcolor shading to flat; added aliases
           to make collection kwargs agree with setter names, so
           updating works; related minor cleanups.
           Removed quiver_classic, scatter_classic, pcolor_classic. - EF

2007-07-26 Major rewrite of mathtext.py, using the TeX box layout model.

           There is one (known) backward incompatible change.  The
           font commands (\cal, \rm, \it, \tt) now behave as TeX does:
           they are in effect until the next font change command or
           the end of the grouping.  Therefore uses of $\cal{R}$
           should be changed to ${\cal R}$.  Alternatively, you may
           use the new LaTeX-style font commands (\mathcal, \mathrm,
           \mathit, \mathtt) which do affect the following group,
           eg. $\mathcal{R}$.

           Other new features include:

           - Math may be interspersed with non-math text.  Any text
             with an even number of $'s (non-escaped) will be sent to
             the mathtext parser for layout.

           - Sub/superscripts are less likely to accidentally overlap.

           - Support for sub/superscripts in either order, eg. $x^i_j$
             and $x_j^i$ are equivalent.

           - Double sub/superscripts (eg. $x_i_j$) are considered
             ambiguous and raise an exception.  Use braces to disambiguate.

           - $\frac{x}{y}$ can be used for displaying fractions.

           - $\sqrt[3]{x}$ can be used to display the radical symbol
             with a root number and body.

           - $\left(\frac{x}{y}\right)$ may be used to create
             parentheses and other delimiters that automatically
             resize to the height of their contents.

           - Spacing around operators etc. is now generally more like
             TeX.

           - Added support (and fonts) for boldface (\bf) and
             sans-serif (\sf) symbols.

           - Log-like function name shortcuts are supported.  For
             example, $\sin(x)$ may be used instead of ${\rm sin}(x)$

           - Limited use of kerning for the easy case (same font)

           Behind the scenes, the pyparsing.py module used for doing
           the math parsing was updated to the latest stable version
           (1.4.6).  A lot of duplicate code was refactored out of the
           Font classes.

Hi,
I have compiled v.0.90.1 on RHEL 5. By default, the GTKAgg backend is being 
used (TkAgg cannot be set, as TkInter is not installed on the system, I 
think. It throws a "NO Module named Tkinter" error).

At any rate, a test session is as follows:
import pylab
pylab.plot ( [1,2,3],[1,2,3],'-or') #Wait for a long time, up to 3-4 minutes
pylab.show() # Display the graph. Quite fast <1sec

This delay is very unusual, and does not happen on my laptop. Does anyone have 
any ideas?

Thanks!
Jose

Ah, yes.  This makes sense now. I used to have my fonts set up this  
way, but then changed them based on one of the newer  
matplotlibrc.default files.  Now I changed it back, and things work  
fine.

   Don't know if this is pertinent to this thread, but I see differences when
viewing LaTeX documents such as an OMR (Optical Mark Reader) form I designed
when viewed as PostScript and as PDF. The former displays the graphics
better than does the latter while the latter better displays the text. In my
case, the printed version combines the highest quality of the two.

I see what's going on here.  Upper-case Greek letters are always upright 
  (non-italic) in mathtext.  TeX does this, and it is apparently a long 
standing American typographic convention.

So, when it goes to print the "\Delta", it looks at "mathtext.rm", which 
in your case you have set to "serif", which causes it to look at the 
setting for "font.serif", in which the first font it finds is "Bitstream 
Vera Serif", which doesn't have Greek characters.

Personally, I like to set the math fonts explicitly, rather than using 
the font categories.  This is what I set for using Arev Sans:

mathtext.cal : Arev Sans:oblique
mathtext.it  : Arev Sans:oblique
mathtext.rm  : Arev Sans
mathtext.bf  : Arev Sans:bold
mathtext.sf  : Arev Sans

I may consider adding "arev" and "arevsans" values to "mathtext.fontset" 
that would do nothing more than set the "mathtext.*" values to 
reasonable defaults to avoid this confusion.  (Which would of course 
require that the Arev fonts are available -- they aren't included with 
matplotlib).  I still think it's useful and reasonable to provide access 
to full font customization, but it would be nice to support the common 
case in a more direct way.

Hope that helps.

Cheers,
Mike

Hi all,

I'm relatively new to matplotlib and what I'll ask to you seems to be simple
but I just can't figure out how to do this. I'd like to change the origin
of  my coordinate system  to the upper left of my axis when I plot my
figures. In matlab I use axis('ij') but in matplotlib I couldn't find
something similar. How will I do this ?

Thank you for your help,

Jaonary

I get this error anytime I try to get a delta.  E.g.:

The line I'm referring to is this --->

/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5/site-packages/matplotlib/mathtext.py:808: 
MathTextWarning: Font 'BitstreamVeraSerif-Roman' does not have a glyph 
for '\Delta'
   MathTextWarning)

Can you send your matplotlibrc settings and the mathtext expression you 
are using?  One or the other of those is causing Vera Serif to be used 
for the \Delta character rather than Arev Sans.

Mike

[This attachment was too large for the list and bounced...  I'm bringing 
the conversation back to the list.]

That may be beyond matplotlib's control.  Matplotlib "requests" a solid 
grey color, but the printing stack (Acrobat, the printer driver or the 
printer itself) could be interpreting that in many ways.  You could 
experiment with various printer settings.

Sorry to not have a more helpful answer.  Perhaps others on this list 
have suggestions.

Cheers,
Mike

The log shows that for some reason it is pulling in 
BitstreamVeraSerif-Roman instead of Arev Sans for that character.  It 
could be that it isn't finding the Arev fonts on your system.

Can you send your matplotlibrc file?  (Particularly the mathtext.* 
options...)  Also, can you set "verbose.level" to "debug-annoying" and 
send us the output?

Cheers,
Mike

I was working on a figure, using mathtext and the Arev Sans fontset,  
and I noticed that \Delta does not display correctly.  In fact, none  
of the capitol greek letters show up.  It claims they are missing  
(and I do not default back to CM).  However, I _know_ Arev Sans has  
\Delta (and the others).

Little \delta and all the other little greek letters are there:

packages/matplotlib/mathtext.py:817: MathTextWarning: Substituting

   warn("Substituting with a dummy symbol.", MathTextWarning)
     <matplotlib.text.Text instance at 0x476f8f30>

\xi$')
     <matplotlib.text.Text instance at 0x478a6e18>


Am I doing something wrong?
