Re: [Matplotlib-users] Update to Matplotlib and Numpy producing error

[Charlie Moad]

I am pretty sure setupext.py used to have these defaults coded in, but
something must have changed.  I haven't had to check default backends
in a long time.  I'll get new builds up asap.

Thanks Darren.  The win32 binaries are updated now.  TkAgg is the
default on all of them, and the OSX binaries already had TkAgg as the
default.

Re: [Matplotlib-users] Build matplotlib 0.98 on OSX

[Charlie Moad]

I just used the default 10.5 compiler.  I didn't use -Os for the whole
run though.  I would just copy the gcc command on the files where it
failed and replace -O3 with -Os.  Kind of lame, I know, but most the
build I did was ran with -O3.

Re: [Matplotlib-users] easy_install and eggs

[Charlie Moad]

So I'll admit that I renamed that file to -fat manually.  The reason I
did this is because it gets named -i386 by default even though it is a
fat build.  Does anyone have a good idea of how to fix this?

Re: [Matplotlib-users] What is the recommended way of Installing MPL 0.9.8 on Leopard?

[Charlie Moad]

I renamed the egg on sf to "matplotlib-0.98.0-py2.5-macosx-10.3.egg".  For
me, setuptools does not try to download the source after installing now.
Unfortunately when I try, "easy_install matplotlib", it still starts
downloading the source instead of the osx binary.  I am not having luck
finding docs on this.

Re: [Matplotlib-users] What is the recommended way of Installing MPL 0.9.8 on Leopard?

[Charlie Moad]

 I have had horrible luck with bdist_mpkg for the last several months.
I did poke at the setuptools code and it looks like we just won't be able to
make it happy with a universal binary.  The preferred extensions have ppc or
i386 in them depending on your arch.  I think the best way to move forward
is to just post binaries for each architecture and not have a universal
build.
 I statically compile in universal builds of libpng and freetype so
end-users don't have to worry about it.  I just build these by hand and the
process is documented here:

I guess the two option are to set "CocoaAgg" as the default backend in your
rc config or run a script with the "-dCocoaAgg" flag.

Scratch that.  It looks pretty good with the latest svn.  Now the question
as to where to put the built docs?  "doc/build/html" seems a bit hidden.
 Has this been discussed yet?

I was going to wait on John about the docs, but I went ahead and cut the
0.98.3 release.  The sdist including the docs was 34MB, so I decided not to
include them.  This would also cause the binaries to be huge if we included
them there as well.  The source release is up/tagged and I will post
binaries asap.

[Matplotlib-users] ANN: matplotlib-0.98.3

[Charlie Moad]

Matplotlib 0.98.3 is now available for download.  We are not pushing an
additional 0.91.x release at this time due to lack of updates to that
branch.

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

- Charlie

=
2008-08-03 Released 0.98.3 at svn r5947

2008-08-01 Backported memory leak fixes in _ttconv.cpp - MGD

2008-07-31 Added masked array support to griddata. - JSW

2008-07-26 Added optional C and reduce_C_function arguments to
   axes.hexbin().  This allows hexbin to accumulate the values
   of C based on the x,y coordinates and display in hexagonal
   bins. - ADS

2008-07-24 Deprecated (raise NotImplementedError) all the mlab2
   functions from matplotlib.mlab out of concern that some of
   them were not clean room implementations. JDH

2008-07-24 Rewrite of a significant portion of the clabel code (class
   ContourLabeler) to improve inlining. - DMK

2008-07-22 Added Barbs polygon collection (similar to Quiver) for plotting
   wind barbs.  Added corresponding helpers to Axes and pyplot as
   well. (examples/pylab_examples/barb_demo.py shows it off.) - RMM

2008-07-21 Added scikits.delaunay as matplotlib.delaunay.  Added griddata
   function in matplotlib.mlab, with example (griddata_demo.py) in
   pylab_examples. griddata function will use mpl_toolkits._natgrid
   if installed.  - JSW

2008-07-21 Re-introduced offset_copy that works in the context of the
   new transforms. - MGD

2008-07-21 Committed patch by Ryan May to add get_offsets and
   set_offsets to Collections base class - EF

2008-07-21 Changed the "asarray" strategy in image.py so that
   colormapping of masked input should work for all
   image types (thanks Klaus Zimmerman) - EF

2008-07-20 Rewrote cbook.delete_masked_points and corresponding
   unit test to support rgb color array inputs, datetime
   inputs, etc. - EF

2008-07-20 Renamed unit/axes_unit.py to cbook_unit.py and modified
   in accord with Ryan's move of delete_masked_points from
   axes to cbook. - EF

2008-07-18 Check for nan and inf in axes.delete_masked_points().
   This should help hexbin and scatter deal with nans. - ADS

2008-07-17 Added ability to manually select contour label locations.
   Also added a waitforbuttonpress function. - DMK

2008-07-17 Fix bug with NaNs at end of path (thanks, Andrew Straw for
   the report) - MGD

2008-07-16 Improve error handling in texmanager, thanks to Ian Henry
   for reporting - DSD

2008-07-12 Added support for external backends with the
   "module://my_backend" syntax - JDH

2008-07-11 Fix memory leak related to shared axes.  Grouper should
   store weak references. - MGD

2008-07-10 Bugfix: crash displaying fontconfig pattern - MGD

2008-07-10 Bugfix: [ 2013963 ] update_datalim_bounds in Axes not works - MGD

Re: [Matplotlib-users] MatPlotLib won't plot

[Charlie Moad]

Can you search your system and see if you have that dll installed somewhere.
 Most likely you will.  If you find it, go to the command prompt and change
to the directory where the dll is.  Then run this command:
Regsvr32 msvcp71.dll

(I don't know if your 64-bit machine uses the command Regsvr64, so try that
too)

Re: [Matplotlib-users] Why is wrapper module called "pylab" ?

[Charlie Moad]

Pylab is just a name for a module in matplotlib that is supposed to mimic
matlab.  I would say its intent it to ease the transition for matlab users.
 It wouldn't really make sense to refer to matplotlib as pylab.  The
matplotlib.pyplot is favored over the pylab module now.

[Matplotlib-users] ANN: matplotlib-0.90.0

[Charlie Moad]

http://www.python.org/pypi/matplotlib/0.90.0

http://sourceforge.net/project/showfiles.php?group_id=80706&package_id=82474&release_id=484485

Binaries will be posted in a few days.

===
2007-02-06 Released 0.90.0 at revision 3003

2007-01-22 Extended the new picker API to text, patches and patch
   collections.  Added support for user customizable pick hit
   testing and attribute tagging of the PickEvent - Details
   and examples in examples/pick_event_demo.py - JDH

2007-01-16 Begun work on a new pick API using the mpl event handling
   frameowrk.  Artists will define their own pick method with
   a configurable epsilon tolerance and return pick attrs.
   All artists that meet the tolerance threshold will fire a
   PickEvent with artist dependent attrs; eg, a Line2D can set
   the indices attribute that shows the indices into the line
   that are within epsilon of the pick point.  See
   examples/pick_event_demo.py.  The implementation of pick
   for the remaining Artists remains to be done, but the core
   infrastructure at the level of event handling is in place
   with a proof-of-concept implementation for Line2D - JDH

2007-01-16 src/_image.cpp: update to use Py_ssize_t (for 64-bit systems).
   Use return value of fread() to prevent warning messages - SC.

2007-01-15 src/_image.cpp: combine buffer_argb32() and buffer_bgra32() into
   a new method color_conv(format) - SC

2007-01-14 backend_cairo.py: update draw_arc() so that
   examples/arctest.py looks correct - SC

2007-01-12 backend_cairo.py: enable clipping. Update draw_image() so that
   examples/contour_demo.py looks correct - SC

2007-01-12 backend_cairo.py: fix draw_image() so that examples/image_demo.py
   now looks correct - SC

2007-01-11 Added Axes.xcorr and Axes.acorr to plot the cross
   correlation of x vs y or the autocorrelation of x.  pylab
   wrappers also provided.  See examples/xcorr_demo.py - JDH

2007-01-10 Added "Subplot.label_outer" method.  It will set the
   visibility of the ticklabels so that yticklabels are only
   visible in the first column and xticklabels are only
   visible in the last row - JDH

2007-01-02 Added additional kwarg documentation - JDH

2006-12-28 Improved error message for nonpositive input to log
   transform; added log kwarg to bar, barh, and hist,
   and modified bar method to behave sensibly by default
   when the ordinate has a log scale.  (This only works
   if the log scale is set before or by the call to bar,
   hence the utility of the log kwarg.) - EF

2006-12-27 backend_cairo.py: update draw_image() and _draw_mathtext() to work
   with numpy - SC

2006-12-20 Fixed xpdf dependency check, which was failing on windows.
   Removed ps2eps dependency check. - DSD

2006-12-19 Added Tim Leslie's spectral patch - JDH

2006-12-17 Added rc param 'axes.formatter.limits' to control
   the default threshold for switching to scientific
   notation. Added convenience method
   Axes.ticklabel_format() for turning scientific notation
   on or off on either or both axes. - EF

2006-12-16 Added ability to turn control scientific notation
   in ScalarFormatter - EF

2006-12-16 Enhanced boxplot to handle more flexible inputs - EF

2006-12-13 Replaced calls to where() in colors.py with much faster
   clip() and putmask() calls; removed inappropriate
   uses of getmaskorNone (which should be needed only
   very rarely); all in response to profiling by
   David Cournapeau.  Also fixed bugs in my 2-D
   array support from 12-09. - EF

2006-12-09 Replaced spy and spy2 with the new spy that combines
   marker and image capabilities - EF

2006-12-09 Added support for plotting 2-D arrays with plot:
   columns are plotted as in Matlab - EF

2006-12-09 Added linewidth kwarg to bar and barh; fixed arg
   checking bugs - EF

2006-12-07 Made pcolormesh argument handling match pcolor;
   fixed kwarg handling problem noted by Pierre GM - EF

2006-12-06 Made pcolor support vector X and/or Y instead of
   requiring 2-D arrays - EF

2006-12-05 Made the default Artist._transform None (rather than
   invoking identity_transform for each artist only to have it
   overridden later).  Use artist.get_transform() rather than
   artist._transform, even in derived classes, so that the
   default transform will be created lazily as needed - JDH

2006-12-03 Added LogNorm to colors.py as illustrated by
   examples/pcolor_log.py, based on suggestion by
   Jim McDonald.  Colorbar modified to handle LogNorm.
   Norms have additional "inverse" method. - EF

2006-12-02 Changed cla

Well, we haven't built any binaries yet.  We pushed a source release
fast to try to get it into Feisty.  Sorry Chris!  With wx2.8 out now
and this being a major release, we definitely need to rethink wx
builds.  We stuck with unicode for 0.87 to avoid confusion.  I would
be happy to hear what wx users think/want.

A while back there was some talk on the dev list about a pure python
blitting method.  I believe 2.8 had features that made this possible.
I don't think anyone actually implemented this though.  I'll have to
check if the current native wx code even compiles with 2.8.  The
pure-python wx interface is still there and works but doesn't allow
for efficient blitting.

   only None-valued vmin, vmax. - EF

2007-03-31 Added a qt-based subplot-adjustment dialog - DSD

2007-03-30 Fixed a bug in backend_qt4, reported on mpl-dev - DSD

2007-03-26 Removed colorbar_classic from figure.py; fixed bug in
   Figure.clf() in which _axobservers was not getting
   cleared.  Modernization and cleanups. - EF

2007-03-26 Refactored some of the units support -- units now live in
   the respective x and y Axis instances.  See also
   API_CHANGES for some alterations to the conversion
   interface.  JDH

2007-03-25 Fix masked array handling in quiver.py for numpy. (Numeric
   and numarray support for masked arrays is broken in other
   ways when using quiver. I didn't pursue that.) - ADS

2007-03-23 Made font_manager.py close opened files. - JKS

2007-03-22 Made imshow default extent match matshow - EF

2007-03-22 Some more niceties for xcorr -- a maxlags option, normed
   now works for xcorr as well as axorr, usevlines is
   supported, and a zero correlation hline is added.  See
   examples/xcorr_demo.py.  Thanks Sameer for the patch.  -
   JDH

2007-03-21 Axes.vlines and Axes.hlines now create and returns a
   LineCollection, not a list of lines.  This is much faster.
   The kwarg signature has changed, so consult the docs.
   Modified Axes.errorbar which uses vlines and hlines.  See
   API_CHANGES; the return signature for these three functions
   is now different

2007-03-20 Refactored units support and added new examples - JDH

2007-03-19 Added Mike's units patch - JDH

2007-03-18 Matshow as an Axes method; test version matshow1() in

2007-03-03 Change barh to take a kwargs dict and pass it to bar.
   Fixes sf bug #1669506.

2007-03-02 Add rc parameter pdf.inheritcolor, which disables all
   color-setting operations in the pdf backend. The idea is
   that you include the resulting file in another program and
   set the colors (both stroke and fill color) there, so you
   can use the same pdf file for e.g. a paper and a
   presentation and have them in the surrounding color. You
   will probably not want to draw figure and axis frames in
   that case, since they would be filled in the same color. - JKS

Re: [Matplotlib-users] question about building from source on windows

[Charlie Moad]

I got a successful build using VS2003 on Vista.  Here is the env dump:


BUILDING MATPLOTLIB

I don't have time to add the proper #ifdef to the cpp file at this

I'll commit the fix to the setupext.py typo.

Did someone want the build?  If so, e-mail me and I'll post it somewhere.

Re: [Matplotlib-users] error on build on windows from SVN

[Charlie Moad]

The error message states that you must be using VS2003.  Python is
compiled with this, so all extensions must also be compiled with it.
If you don't have a copy of VS2003 your best bet is to just use
cygwin/mingw.

I have posted fresh win32 eggs and exe's on SF.  I explicitly removed
the inclusion of msvcp from distutils in numpy.  Please give them a
try and let me know if you have any more problems.  Note: I just
posted the files so it might take a while for them to propagate.

Re: [Matplotlib-users] eggs or pythonmac packages on OS X?

[Charlie Moad]

I primarily follow the dev list, but you've caught my eye. ;)

So to be clear, you would just like me to install some other tcl/tk
before I do the "official" matplotlib osx binaries.  What package
should I be installing and where should I get it from.  As long as it
still works with the bundled tck/tk I would have no problems doing
this.

Thanks,

Re: [Matplotlib-users] Unable to compile matplotlib 0.91.2 on windows

Just a guess.  Did you download the visual studio static libraries
instead of the mingw ones?  Those linking symbols listed lend me to
think this.  The visual studio ones end in "_vs.tar.gz".

You want this:

Re: [Matplotlib-users] Can't run matplotlib without "tk" backend on windows?

[Charlie Moad]

You need to set a different backend in your matplotlibrc or specify it first.

import matplotlib
matplotlib.use('Agg')

You can also run scripts passing the backend:

python lab1_ex2.py -dAgg

That's fine.  I didn't use setup.cfg for the latest binaries though.

Re: [Matplotlib-users] Problem installing 0.91.2 egg on OS X 10.4

[Charlie Moad]

Apparently a dynamic link snuck into the build.  Typically everything
is statically included.  You can see this by running the following
command:

uaternion:matplotlib cmoad$ otool -L ft2font.so
ft2font.so:
/usr/local/lib/libfreetype.6.dylib (compatibility version 10.0.0,
current version 10.16.0)
/usr/lib/libz.1.dylib (compatibility version 1.0.0, current version 
1.2.3)
/usr/lib/libstdc++.6.dylib (compatibility version 7.0.0, current 
version 7.4.0)
/usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
version 88.3.6)
/usr/lib/libgcc_s.1.dylib (compatibility version 1.0.0, current version 
1.0.0)

I will created and post a new build asap.

Thanks,
 Charlie

Re: [Matplotlib-users] Static linking problem on matplotlib eggs

[Charlie Moad]

I just had to rebuild the OSX binary because a similar reason.  I
forgot to change the basedir['darwin'] entry in setupext.py.  Around
line 50.

Change:
'darwin' : ['/sw/lib/freetype2', '/sw/lib/freetype219', '/usr/local',
'/usr', '/sw', '/usr/X11R6'],
To:
'darwin' : [],

This will ensure you don't pick up shared libraries over the static
ones since they are preferred by gcc.

Re: [Matplotlib-users] Mac OSX binary missing setup.py

You shouldn't ever find a setup.py file in a binary distribution.  It
is there for building purposes, hence should be with the source
distributions.

Re: [Matplotlib-users] Install problem on Leopard

[Charlie Moad]

I agree you are not using a universal build of python to compile matplotlib.
 You cannot pass in the "-arch i386 -arch ppc" flags.  Only pass the
architecture of your computer.

I tried it after seeing your message.  Indeed I got the same internal gcc
failure.  This is a compiler problem the with the gcc on 10.5.2 (and
10.5.1I think).  I found the same error message on many google hits
outside of
matplotlib.  Your suggestion of compiling with -Os for the two problem files
worked fine for me.

Actually I do use VS2003 for the releases.  I haven't tried a build in a

You can see these changes here:

Re: [Matplotlib-users] py4science OSX installation problems

[Charlie Moad]

The internal compiler error is something we are all running into right now.
 The only known fix is to run the build with the gcc flag "-Os" instead of
"-O3".  You should be able to do this by setting the environment during your
build:
CFLAGS="-Os" python setup.py build

Re: [Matplotlib-users] can't import pylab

The 0.87.2 release requires numpy-0.9.6.

Hi,

I'm using Python 2.4.1, numpy-0.9.8, and matplotlib-0.87.2 on a Windows
XP computer.
Problem is that any attempt to import pylab results in a crash.
Using "python -v", the culprit seems to be the following line:

#
c:\Python24\lib\site-packages\matplotlib\_transforms.pyc
matches
c:\Python24\lib\site-packages\matplotlib\_transforms.py
import matplotlib._transforms # precompiled from
c:\Python24\lib\site-packages\matplotlib\_transforms.pyc

Any ideas and solutions to this issue?

The only way you could have conflicting data sources is if
MATPLOTLIBDATA is defined in your environment.  If someone is capable
of setting that I am inclined to think they might know what to do in
case of an error.  If that env var is not set, then mpl looks inside
the its module.  Different installs will not see the others.  We
finally have a special case for frozen installations.  It has
primarily been made for py2exe, in which you should have a folder
called 'matplotlibdata' in your app's bundle.

The second location should be:
Frameworks/Python.Framework/2.4/lib/python2.4/matplotlib/mpl-data

Are you using an old version of matplotlib?

You can remove the MATPLOTLIBDATA env var from os.environ in your code.

In my experience with distributing apps with matplotlib, I have known
in advanced the packages I want to use.  For example, if I know I am
going to bundle Tkinter and numpy, then I make sure I have the
following before using any matplotlib commands.

import matplotlib
matplotlib.use('TkAgg')
matplotlib.rcParams['numerix'] = 'numpy'

This makes sure your app uses you desired backend modules no matter
what the global config says.

Good luck,
 Charlie

Agreed.  I think we are tied closely enough to numpy that a minor
release is justified.  A 0.88 release doesn't seem justified yet, so I
could push a 0.87.3 barring any outstanding bugs.

2006-05-27 Committed a patch to prevent stroking zero-width lines in
   the svg backend - DSD

2006-05-24 Fixed colorbar positioning bug identified by Helge
   Avlesen, and improved the algorithm; added a 'pad'
   kwarg to control the spacing between colorbar and
   parent axes. - EF

2006-05-23 Changed color handling so that collection initializers
   can take any mpl color arg or sequence of args; deprecated
   float as grayscale, replaced by string representation of
   float. - EF

2006-05-19 Fixed bug: plot failed if all points were masked - EF

2006-05-19 Added custom symbol option to scatter - JDH

2006-05-18 New example, multi_image.py; colorbar fixed to show
   offset text when the ScalarFormatter is used; FixedFormatter
   augmented to accept and display offset text. - EF

2006-05-14 New colorbar; old one is renamed to colorbar_classic.
   New colorbar code is in colorbar.py, with wrappers in
   figure.py and pylab.py.
   Fixed aspect-handling bug reported by Michael Mossey.
   Made backend_bases.draw_quad_mesh() run.- EF

2006-05-08 Changed handling of end ranges in contourf: replaced
   "clip-ends" kwarg with "extend".  See docstring for

Danny, can you try deleting your .matplotlib folder and trying again?

Sounds like you need to upgrade numpy to 0.9.8.

Re: [Matplotlib-users] wxmsw26uh_vc.dll and matplotlib 0.87

[Charlie Moad]

As you have found, the matplotlib binaries are built using the unicode
version of wxpython.  If you are not using blitting, then you can just
go in any delete the "matplotlib/backends/_wxagg.so" (.pyd for
windows) file from the installed matplotlib module.  Then the
pure-python wx backend will be used instead, and it should work fine
with both versions of wx.

===
2006-07-11 Released 0.87.4 at revision 2558

2006-07-07 Fixed a usetex bug with older versions of latex - DSD

2006-07-07 Add compatibility for NumPy 1.0 - TEO

2006-06-29 Added a Qt4Agg backend. Thank you James Amundson - DSD

2006-06-26 Fixed a usetex bug. On windows, usetex will prcess
   postscript output in the current directory rather than
   in a temp directory. This is due to the use of spaces
   and tildes in windows paths, which cause problems with
   latex. The subprocess module is no longer used. - DSD

2006-06-22 Various changes to bar(), barh(), and hist().
   Added 'edgecolor' keyword arg to bar() and barh().
   The x and y args in barh() have been renamed to width
   and bottom respectively, and their order has been swapped
   to maintain a (position, value) order ala matlab. left,
   height, width and bottom args can now all be scalars or
   sequences. barh() now defaults to edge alignment instead
   of center alignment. Added a keyword arg 'align' to bar(),
   barh() and hist() that controls between edge or center bar
   alignment. Fixed ignoring the rcParams['patch.facecolor']
   for bar color in bar() and barh(). Fixed ignoring the
   rcParams['lines.color'] for error bar color in bar()
   and barh(). Fixed a bug where patches would be cleared
   when error bars were plotted if rcParams['axes.hold']
   was False. - MAS

2006-06-22 Added support for numerix 2-D arrays as alternatives to
   a sequence of (x,y) tuples for specifying paths in
   collections, quiver, contour, pcolor, transforms.
   Fixed contour bug involving setting limits for
   color mapping.  Added numpy-style all() to numerix. - EF

2006-06-20 Added custom FigureClass hook to pylab interface - see
   examples/custom_figure_class.py

2006-06-16 Added colormaps from gist (gist_earth, gist_stern,
   gist_rainbow, gist_gray, gist_yarg, gist_heat, gist_ncar) - JW

2006-06-16 Added a pointer to parent in figure canvas so you can
   access the container with fig.canvas.manager.  Useful if
   you want to set the window title, eg in gtk
   fig.canvas.manager.window.set_title, though a GUI neutral
   method would be preferable JDH

2006-06-16 Fixed colorbar.py to handle indexed colors (i.e.,
   norm = no_norm()) by centering each colored region
   on its index. - EF

2006-06-15 Added scalex and scaley to Axes.autoscale_view to support
   selective autoscaling just the x or y axis, and supported
   these command in plot so you can say plot(something,
   scaley=False) and just the x axis will be autoscaled.
   Modified axvline and axhline to support this, so for
   example axvline will no longer autoscale the y axis. JDH

2006-06-13 Fix so numpy updates are backward compatible - TEO

2006-06-12 Updated numerix to handle numpy restructuring of
   oldnumeric - TEO

2006-06-12 Updated numerix.fft to handle numpy restructuring
   Added ImportError to numerix.linear_algebra for numpy -TEO

2006-06-11 Added quiverkey command to pylab and Axes, using
   QuiverKey class in quiver.py.  Changed pylab and Axes
   to use quiver2 if possible, but drop back to the
   newly-renamed quiver_classic if necessary.  Modified
   examples/quiver_demo.py to illustrate the new quiver
   and quiverkey.  Changed LineCollection implementation
   slightly to improve compatibility with PolyCollection. - EF

2006-06-11 Fixed a usetex bug for windows, running latex on files
   with spaces in their names or paths was failing - DSD

2006-06-09 Made additions to numerix, changes to quiver to make it
   work with all numeric flavors. - EF

2006-06-09 Added quiver2 function to pylab and method to axes,
   with implementation via a Quiver class in quiver.py.
   quiver2 will replace quiver before the next release;
   it is placed alongside it initially to facilitate
   testing and transition. See also
   examples/quiver2_demo.py. - EF

2006-06-08 Minor bug fix to make ticker.py draw proper minus signs
   with usetex - DSD

Re: [Matplotlib-users] ANN: matplotlib-0.87.4 (bugfix release for enthon)

The modules have been imported into the matplotlib repository, and
they are semi-functional.  They still need a lot of work though.
There is a new example, simple3d_oo.py.

Thanks for the note.  This is a known issue and has been addressed in

They are fixed in the matplotlib modules, but I guess I was referring
to the issue existing in mplot3d. Maybe the scipy wiki should mention
that it doesn't work with newer versions of mpl.  I don't know the
originally targeted version though.

This error used to come up with mingw and python2.4 builds, but now we

Re: [Matplotlib-users] Missing dll in windows build 0.87.4

[Charlie Moad]

The mingw/2.4 build still works.  There are instructions at the top of
the setupext.py file.  The dll linking error you are getting is
something we ran into a lot.  If you have numpy installed distutils
will use the numpy\distutils\mingw32ccompiler.py file.  In the
Mingw32CCompiler class remove all links to "msvcr71".  In my version
of numpy just comment out the whole if block at line 127.

Not really.  I am using Visual Studio for the build in which I have
never seen or heard of this error occuring.  This was a mingw problem,
and the fix I mentioned was what we did when the builds were done with
mingw.

We got this error no matter what.  I had the file all over the place
and the mingw builds still complained.

Re: [Matplotlib-users] matplotlib/wxmpl/numpy conflict on windows xp: runtime error, C-API ?

[Charlie Moad]

I am guessing you installed numpy1.0b1.  You need to use 0.9.8.

It will just overwrite the old files, so normally you don't run into
problems.  There is no defacto way to remove the modules though.  It
is usually pretty obvious what needs to be removed from the
site-packages folder.  Sometimes it is a little more difficult.
Matplotlib installs matplotlib, pytz, dateutil, and pylab.py.

Re: [Matplotlib-users] installation problem

[Charlie Moad]

It looks like Travis committed a numpy 1.0 compatibility fix on July
7th.  It includes the header which addresses your error.  You will
have to use >=matplotlib-0.87.4 if you want to use the latest numpy.

What version of numpy are you using, and was it installed from source
or package?

What's the error you are getting with tk?  Do you have the dev

For non-interactive pylab, just type "show()" after your code above.
The -pylab option John mentioned is the ideal way to go though.

Before you have to write back the latest matplotlib release only
works with numpy-0.9.8.

Try deleting your ~/.matplotlib folder to clear you font cache.

Sounds like you got it working then.  Mpl 0.87.4 requires numpy-0.9.8.
 I think 0.87.3 requires 0.9.6, but I am starting to forget all the
number combinations.  Once numpy 1.0 is released, this mess should be
gone.

A unicode character in your font path?  Weird.  Try deleting your font
cache in your ~/.matplotlib folder.  On windows it is somewhere in
your home folder.

Look in at the widget examples.  There is a new Lasso widget for
"doodling" and a RectangleSelector.

You probably have numpy-0.9.6 installed.  0.87.4 requires numpy-0.9.8.

Re: [Matplotlib-users] matplotlib/wxmpl/numpy conflict on windows xp: runtime error, C-API ?

[Charlie Moad]

Here is a link to a build that works with numpy-1.0b1.  Pushing a
release now for 1.0 might be pointless, since the C-api could possibly
change and break compatibility again.  After all, it still is a beta.

Re: [Matplotlib-users] Problems upgrading to mpl 0.87.4

[Charlie Moad]

Matplotlib didn't used to link against the wxpython c-api.  The recent
versions are linked against the unicode version of wx, not the ansi.
You can install the unicode version.  We are trying to decide how to
handle this.

Re: [Matplotlib-users] Is matplotlib compatible whith PyQt4 ?

[Charlie Moad]

I am not the author of it.  I just may of made the last commits to it.
 I am pretty sure Darren wrote the initial implimentatin.  The only
example that exists right now is animation_blit_qt4.py.

Re: [Matplotlib-users] MSVCP71.dll required by matplotlib

[Charlie Moad]

We used to explicitly remove the link when we used mingw for the
python2.4 build.  The VS build didn't seem to suffer from the problem,
but not these reports are coming up.  I might try removing the link
again.  Otherwise I will look into including it.

Please follow the segfault instructions and get back to us.

When running the examples with -dGtkAgg, gtk_spreadsheet.py
embedding_in_gtk.py embedding_in_gtk3.py worked, embedding_in_gtk2.py
pylab_with_gtk.py failed and coredumped without any prompts.

My system is NetBSD AMD64-3.0. With python 2.4.3, gtk+-2.8.19, pygtk-2.8.6.

Is there someting wrong with my system? Thanks for your suggestion.

Since your error was with gtk try:

import matplotlib.backends._gtkagg

I am guessing that will fail.  You might try reinstalling gtk and
pygtk.  I doubt anyone has NetBSD to confirm your error though.

Re: [Matplotlib-users] 3d Plotting

The colors come from the current colormap.  You can go all out and
make your own colormap and color based on index using your map.  I
don't know how to do that off the top of my head though.

Agreed.  fig.set_figsize seems redundant, so I am changing it to
fig.set_size_inches.  The old one will still be present, but will
issue a deprecation warning.  I'll commit these changes soon.

You need to install the tcl/tk headers as Darren mentioned.  I just
install ActiveTcl and the build should pick up on it no problem.

[Matplotlib-users] ANN: matplotlib-0.87.5

[Charlie Moad]

Minor rev bump for numpy 1.0b5 compatibility.  This release should
remain compatible with future 1.0 releases of numpy.

http://cheeseshop.python.org/pypi/matplotlib/
http://sourceforge.net/project/showfiles.php?group_id=80706&package_id=82474

===
2006-09-05 Released 0.87.5 at revision 2761

2006-09-04 Added nxutils for some numeric add-on extension code --
   specifically a better/more efficient inside polygon tester 
(see
   unit/inside_poly_*.py) - JDH

2006-09-04 Made bitstream fonts the rc default - JDH

2006-08-31 Fixed alpha-handling bug in ColorConverter, affecting
   collections in general and contour/contourf in
   particular. - EF

2006-08-30 ft2font.cpp: Added draw_rect_filled method (now used by mathtext2
   to draw the fraction bar) to FT2Font - ES

2006-08-29 setupext.py: wrap calls to tk.getvar() with str(). On some
   systems, getvar returns a Tcl_Obj instead of a string - DSD

2006-08-28 mathtext2.py: Sub/superscripts can now be complex (i.e.
   fractions etc.). The demo is also updated - ES

2006-08-28 font_manager.py: Added /usr/local/share/fonts to list of
   X11 font directories - DSD

2006-08-28 mahtext2.py: Initial support for complex fractions. Also,
   rendering is now completely separated from parsing. The
   sub/superscripts now work better.
   Updated the mathtext2_demo.py - ES

2006-08-27 qt backends: don't create a QApplication when backend is
   imported, do it when the FigureCanvasQt is created. Simplifies

Re: [Matplotlib-users] installation

VS2003.Net is needed to easily build the python 2.4 version. (e.g.
python setup.py build)  You can also follow the mingw instructions for
a more open-source way of building matplotlib for windows.  We still
have to do this for python 2.3.  You can supposedly download the .net
compiler tools for free, but I haven't tried.  I am pasting my
previous post since I didn't re-all.

Sorry all for the error.  I just uploaded "working" (at least for me)
versions to sourceforge again.  For those who are sicking of playing
with mirrors here is a direct download.  Don't expect this link to be
good for a long time though.

Try the ones I added to the link above.  I already had a mpl build on

I am guessing you are on an intel machine.  These can safely be ignored.

Sounds like wx is your problem right now, so please try my suggestion above.

Re: [Matplotlib-users] 0.87.5 Installation alongside Numpy/SciPy [OS X]

[Charlie Moad]

mpl 0.87.5 is compiled against numpy 1.0b5.  It should remain
compatible with future release of 1.0.
