Looks like a bug -- I see the same thing with twinx. Could you file
this one of the sf site? I took a look through the axis code but
couldn't find the culprit. I'm CC Baptiste who wrote the code --
maybe he has some insight.
Thanks

This is currently a work in progress. There should be support for
this in matplotlib CVS. Eg you can call
 manager.set_canvas_size(width, height)
where manager is a backend "FigureManager" instance.
You can access this from pylab with 
manager = get_current_fig_manager()
The API for this is still under discussion and subject to change, and
only implemented for GTK* currently, I believe.

Unfortunately, that is probably not the issue. I increment the counter
every time a new figure() is called:
 # If new plot, increment counter
 if new:
 self.plot_counter +=3D 1
 figure(self.plot_counter,figsize=3D(10,6))
I have used print statements in this block to guarantee the count.

Ryan,
Could you please test and see if the segfaults continue to occur when the 
WxAgg accelerator has been disabled? Also, short script that reproduces this 
problem would be appreciated. Thanks.
Ken

Philippe,
I believe that Figure.delaxes() does what you want:
	# create a subplot and add it to a figure
	ax = Subplot(fig,111)
	fig.add_subplot(ax)
	# remove the subplot
	fig.delaxes(ax)
	# add it to another figure
	anotherFigure.add_subplot(ax)

I use Matplotlib to plot output from my Bayesian simulation package,
PyMC. I essentially generate a series of 2-pane plots with a line plot
and a histogram on each. Between plots, the figure() function is
called:
figure(self.plot_counter,figsize=3D(10,6))
which should generate a new canvas for plotting. Every so often,
however, this does not happen, resulting in superimposed plots:

Anyone else have this problem? Is there a solution?

I haven't seen this problem before, would you post a minimal example?

I add another question linked to the previouns one.
as we sepcify two times the link between figure and subplot (axes) when 
we make subplot manually:
ax = Subplot(fig,111)
fig.add_subplot(ax) 
Is it possible after that to break the link between a figure and a 
subplot and to add the subplot to another figure?
Thanks a lot for any answer,
Philippe Collet

Hi John and list,

First, thanks to Darren and John and anyone else who helped with the
usetex functionality. I am really impressed.
I searched the list for bounding box and saw that there are a lot of
posts on this subject. But didn't see anything the specifically deals
with my problem.
I am using:

The bounding box goes tightly around the figure but does not include
the labels. Is there a way to add a pad around the figure or some
other way to solve this problem?

Hi All,
This is just a RFC for a project that's been in the back of my mind for a few
years now : integration of a data visualization system with a CMS. In general
terms, I think it would be nice to have the kind of functionnality reserved to
desktop backends TTW :). Of course, the stateless nature of HTTP makes some
things hard or impossible to achieve efficiently, but with "console type" web
applications sprouting all over the place now with the many AJAX frameworks out
there, I believe the time is ripe for at least a first try.
Over the last few months, I have become acquainted with Plone 2 as well as a
variety of Python utilities (including matplotlib!). I've recently been playing
with Mochikit (TurboGear's AJAX provider) within a Plone 2 environment. With
the Zope/Plone community moving towards a Zope 3 base that as far as I can tell
is closer to the rest of the Python world than Zope 2 is, I feel confident that
Zope will be a great system to incorporate a data visualization system into. 
Does anyone have links/pointers to issues related to such an integration scheme
in general ? Is a broader integration of SciPy with a CMS like Zope unrealistic
? I'm approaching the problem from a layman's perspective that has a bit of
computer literacy. Maybe I could illustrate what I'm trying to achieve by an
example.
I have some sensors that measure a bunch of parameters (water quality, air
pollution ...). There is a bunch of locations where those sensors are either
deployed in situ or are used sporadically (e.g. a handheld instrument). I want
to store sensor descriptions in a CMS together with a host of related info
(calibration data, maintenance history) and be able to purpose a sensor's
representation in some standard form (e.g. SensorML). I want to store
measurement stations also as CMS objects (lat/lon, picture of the station,
instruments used ...). I'm currently storing Measurements as CMS objects as
well (contained in MeasurementStation objects), but that is temporary :
individual measurements will be stored in a standard relational DB.
Users can view measurements as tables and as graphics. What I'd like to do
eventually is to provide a full GUI for users to control their plot layout and
that's where the integration of a full-fledged data visualization system comes
into play. An easy solution would be to provide an invisible data download to
some temp directory so that users could use TkAgg on their desktops, but I'd
really like to avoid this "applet-style" solution and try and find an AJAX
solution : query the server for bits of data as needed.
Is anyone interested by this topic ? Sorry for potentially polluting this list,
but I couldn't find a better place ...
Yves Moisan

I just downloaded the latest cvs snapshot and did a sudo python
setup.py install. This process finished cleanly, but if I use the
WXAgg backend, pylab.show() causes a seg fault. How do I get more
information to fix this problem? The TkAgg backend seems to work
fine. I am running ubuntu Breezy Linux.

Dear All,
I have hacked a bit at texmanager.py and backend_ps.py in order to
generate "superior" text output using LaTeX.
It involves "including" a user specific "low level font command" input
file useing some "new" rcParams and the savefig command with the PS
backend in you main "pylab" script:
...
rcParams['font.latex.inputfile']=3D'True'
rcParams['font.latex.inputfile.filename']=3D'mypresentation.llfc'
savefig('myeps.eps')
...
The "low level font command" input file has the following included:
\fontencoding{T1}		% T1 - Latin 1, etc.
\fontfamily{phv}		% cmr - Computer Modern Roman, ptm -
Times-Roman, phv - Helvetica, etc.
\fontseries{m}		% m - Medium, b - Bold, bc - Bold Condensed, bx
- Bold Expanded
\fontshape{n}		% n - Upright (Normal), it - Italic, sl -
Slanted,
				% sc - Small Caps, ui - Upright Italics,
ol - Outline
\selectfont			% Above font changes will now become
effective
or for those who know all the abreviations by hart:
=20
\usefont{T1}{phv}{m}{n}
Attached are examples of three "low level font command" files for
different "application", e.g. a Thesis, a Presentation or an Article...
In texmanager.py the "TexManager.get_tex_command" needs to be changed
to:
...
 def get_tex_command(self, tex, fname):
 fh =3D file(fname, 'w')
 if rcParams['text.tex.engine'] =3D=3D 'latex':

For other newbies like myself,
Although flushing the ~/.matplotlibrc/tex.cache is an importend thing to
remember, which I did, but forgot to mention (see PS at the bottom), the
reason why:
...
font packagesfont.latex.package : helvet
...
Did not give my the desired results (for inclusion into a Beamer LaTeX
Document Class presentation, was that:
 "... By default, LaTeX selects a Roman typeface as the document
font...", The LaTeX Companion, Second Edition, p 373
The following line needs to be "placed" in the preamble of the "LaTeX
document" created by texmanager.py and backend_ps.py:
\renewcommand\familydefault{\sfdefault}

PS: A rcParam['tex.cache.flush']=3D'True' option would be an usefull

If you use the exact same text then it will not change the font =20
because matplotlib caches the tex redering of text by the name of the =20
text. You have to delete
the matplotlib tex cache in ~/.matplotlibrc/tex.cache. That will =20
force it to regenerate the text using the new font.
For example if your plot has a label "Meters" then matplotlib will =20
use the cached rendering of "Meters". It isn't smart enough to notice =20
that the cached version uses a different font and therefore must be =20
re-rendered.

In my understanding, code which imports GPL'd code is obligated to
abide by the GPL restrictions itself if you want to distribute it,
specifically the copyleft part that says derived works must be open
source and distributed under the GPL. So if mpl imports a GPL module,
mpl, then any code which is for distribution that imports matplotlib
is required to be distributed under the terms of the GPL. This is
clearly unacceptable to someone who wants to distribute products that
use mpl under a proprietary license. The LGPL was introduced to solve
this problem, and it basically says that you can import it and use it
but if you change the LGPL library the library changes must be
distributed under the LGPL. I don't find it particularly
objectionable to use code which has an LGPL license, but given an
alternative, would rather have a BSD type license which is
"unencumbered".
Basically, the GPL is not particularly liberating, since it makes
strong statements about what you can do with code that uses GPL code.

You can change the tick formatter by setting the yaxis "major tick
formatter". See the help for the matplotlib ticker module in the
online class docs, the chapter of the User's Guide on tick locators
and formatters, and the examples major_minor_demo*.py. In particular,
you will probably want a FormatStrFormatter

Dear All MiKTeX/win32 users,
With the following lines in my matplotlibrc file:
...
text.usetex : 	True =20
text.tex.engine :	latex
...
I can generating beautiful LaTeX output for my text labels, I now have
difficulty changing the font from the default, "Computer Times Roman" to
anything else..
The following line in my matplotlibrc file:
...
font packagesfont.latex.package :	helvet=20
...
Have no effect...
Changing "helvet" to:
times, txfonts, pxfont, arial, etc. have also no effect although these
packages are installed...
Even hardcoding, "\usepackage{helvet}" into backend_ps.py, has no
effect:
...
 if rcParams['text.usetex']:
 if rcParams['text.tex.engine'] =3D=3D 'latex':=20
 fontpackage =3D rcParams['font.latex.package']
 else:=20
 fontpackage =3D 'type1cm'
 pw, ph =3D defaultPaperSize
 if width>pw-2 or height>ph-2: pw,ph =3D
_get_papersize(width,height)
 print >>latexh, r"""\documentclass{scrartcl}
\usepackage{%s}
\usepackage{helvet}
\usepackage{psfrag}
...
Any ideas...?
Vriendelik die uwe,

Hi,
I'm trying to make a histogram. matplotlib makes it perfectly, except 
for the numbering on the y axis, which it changes by a factor of e4, 
example: http://junker.org/~mlubin/hist.jpg. How can I make it use 
standard notation instead of scientific notation?
Thanks,
Miles
