Of course it does <smacks head>.  Sorry for bothering the list with my
stupidity.

Jeremy

Your data repeat itself twice.
Please check your data and report back if you still see the problem.

Thanks JJ,

I wonder when will I learn to fix my own rent :)

Glad to have you here always responding with a quick solution.

If that symbol is included in any of the font (I don't know of any),
you can simply use them.

Or, you need to create your own path. There are a few ways to do it,
and I guess using scatter is one of the easiest.

   zap0 = [[-1.,0.], [-0.5, 0.5], [0.,0.], [0.5,-0.5],[1.,0.]]
   zap = zap0 + zap0[-1:0:-1] # same verts but backward. the verts
                              # gets closed internally.

   scatter([1.],[1.], s=100, marker=None,
           verts=zap)

The below line is supposed to work but it does not, which is a bug.

  pary.axis["right"].label.set_rotation(270)

Meanwhile, use may use something like below,

  pary.axis["right"].get_helper()._label_angles["right"]=270

Hello list.  I am having trouble with an extraneous line drawn from my
last data point back to the first data point.  I I don't quite know
why this is happening and was hoping someone could tell me what was
wrong.  I have attached an example; the commands I used are copied
below.

Thanks,
Jeremy

It is a limitation of pcolor, which uses a PolyCollection--very flexible 
and general, but very inefficient for simple cases with many polygons. 
With a regular grid, you can simply use an image, for the highest 
performance.  pcolormesh is also a good alternative, and more general 
than image.  There is no pyplot wrapper, but the Axes.pcolorfast method 
can use any of three different algorithms to achieve pcolor-like results 
with the highest possible efficiency for a given grid.

Hello,

One more figure and one more question.
http://img263.imageshack.us/img263/6454/labelrotation.png

I want to rotate the 2nd y-axis label "Air Temperature" upside down in other
words rotating 180 degree while A staying up. Unfortunately set_rotation
method is not available to a SubplotHost instance.

Any ideas how to achieve this?

    fig = plt.figure(figsize=(10,8))
    host = SubplotHost(fig, 111)
    fig.add_subplot(host)
    pary = host.twinx()

    host.set_xlabel("Time [sfm]")
    host.set_ylabel("Pressure Altitude [m]")
    pary.set_ylabel(r"Air Temperature [$^o\hspace{-0.5}C$]")
    #pary.set_rotation("270")

Hi all,

Typing this (on ipython prompt with the relevant libraries imported)

x = linspace(0,1.0,500)
y = linspace(0,1.0,500)
xg,yg = meshgrid(x,y)
c = rand(len(x), len(y))
pcolor(xg,yg,c)

Makes the ipython process to grow to have about 400 Mb of resident
memory and it takes ages for the plot to appear (a 1000x1000 image
just makes my 1 Gb system trash helplessly).

But, using pcolormesh instead of pcolor in the last line of the script
above works ok, the plot appears almost immediately, and the memory
consumption of the ipython process only doubles, i.e. grows about 30
Mb.

Is this a bug or am I doing something wrong? I'm using
python-matplotlib 0.99.0-1 from Debian.

Best,

Teemu

Thanks Mike, that did the trick.

I was giving a space before units to make them look equal. Yours is much
neater.

Has this bug submitted on SF. I can go ahead a file one if not.

Same here, I had no problem with the RC, but frankly did very little

No idea, I see it when I try to run barchart_demo.py (MPL example) which 
uses pyplot.

I get this error:


Free translation: can't start program as MSVCP71.dll is missing.

As you can see it looks just about anywhere for MSVCP71.dll but not in 
c:\Python25.

If I change the path (i.e. change the start in folder for the short cut 
which starts Boa - which I use in turn to run the script) the script 
runs but no output nor no errors are shown.

Just tried to run the barchart_demo.py in Python Shell (idle) and I see 
the same exception as I see in Boa.

> What backend are you using, and does the problem occur with other matplotlib

>   
If I do this import in the shell:
import matplotlib.pyplot as plt

I get an error window "Unhandled exception" which allows to Abort, 
Retry, Ignore.  It does not provide any useful information and I can't 
find any log file either.

I normally use the "WXAgg" backend, if I run a small sample using this I 
get the window error that python.exe has stopped working - again without 
any exception or log file, only option is "close the program", I let it 
try and find a solution on the web (instead of cancel it) but without 
anything.

I can run wxPython applications without problem, i.e. the IDE Boa or my 
own shareware as long as the matplotlib code is not been executed, if I 
try to bring up the frame with it then I get the python.exe has stopped 
error or it just hangs.

Searching on the web I found this thread which is similar but it is with 
Python 2.6.
http://www.nabble.com/matplotlib._path-failed-on-windows-build-for-Python-2.6-td22963286.html

I might try and do a Py 2.6.3 install and see if I get this to work - 
don't really want to move to 2.6 yet.

If I can provide anything else which might help to find what is 
happening, please do not hesitate to ask (only thing I can't do is 
compile it here as I don't know C++ at all.

I think you misunderstood what I meant by proxy artist (I'm not sure
if this is a right choice of the word, as a matter of fact).

Again, PolyCollection instance that is returned by fill_between is not
supported by legend.
Therefore, you have to use other kind of artist (which I call proxy
artist) that is supported.
The example I linked just show how to use Rectangle as a proxy.

Figured it out:

import matplotlib.mlab as mlab
import mpl_toolkits.gtktools as gtktools
formatd = dict(
            x = mlab.FormatFloat(2),
            y = mlab.FormatFloat(2)
        )
r=mlab.csv2rec('file.csv',names=('X','Y'))
v=gtktools.rec2gtk(r,formatd=formatd)
for c in v.treeview.get_columns():
   c.set_alignment(0.5)
view.show()

Hi, Werner.  I've been running the release candidate of Windows 7 and haven't
encountered that issue.  My Python installation is that of Python(x,y) 2.1.17,
which includes the same version of Python as yours, and I'm using a build of
matplotlib from SVN, although I previously used version 0.99.0 without DLL
trouble.

On my machine, I found msvcp71.dll in several directories under
C:\Python25\Lib\site-packages (including site-packages\wx-2.8-msw-unicode\wx),
in C:\Windows\System32, and in several locations under C:\Program Files, but
not in C:\Python25.  There is a similarly-named msvcr71.dll in C:\Python25.

I'm wondering whether and how msvcp71.dll is related to the traceback to the
_path module, because the _path module comprises a .pyd (~= .dll) file.  You
might start Python, enter "from matplotlib._path import affine_transform", and
see whether the import is successful.

Are you able to run other matplotlib examples?  Can you open a figure window?
What backend are you using, and does the problem occur with other matplotlib
backends, both GUI and non-GUI?

It's a bug without an easy solution.  Realistically, we probably need to 
make two passes with the mathtext parser to determine spacing.

A workaround is to use the \hspace command:

   r"[#/$cm^3\hspace{-0.3}$]"

Hello,

Not that I like asking the same question again and again, but I just
couldn't find a way to fix one annoyance on my figures when I use mathtex
formatted labels. Here is one example figure:
http://img14.imageshack.us/img14/4443/mathtex.png

# Set the label
host.set_ylabel(r"DMT CCN Concentration [#/$cm^3$]")

On the y-label, I always get an extra space after the formatted text even if
I don't explicitly put myself. What is the known cure for this issue? This
figure and similars will go onto my poster, and thesis and further on a
paper. I would really like to know if there a way to fix this by making some
changes on my code or matplotlibrc file.

Thanks.

Here is the relevant sections of my rc file:

### FONT
#
# font properties used by text.Text.  See
# http://matplotlib.sourceforge.net/matplotlib.font_manager.html for more
# information on font properties.  The 6 font properties used for font
# matching are given below with their default values.
#
# The font.family property has five values: 'serif' (e.g. Times),
# 'sans-serif' (e.g. Helvetica), 'cursive' (e.g. Zapf-Chancery),
# 'fantasy' (e.g. Western), and 'monospace' (e.g. Courier).  Each of
# these font families has a default list of font names in decreasing
# order of priority associated with them.
#
# The font.style property has three values: normal (or roman), italic
# or oblique.  The oblique style will be used for italic, if it is not
# present.
#
# The font.variant property has two values: normal or small-caps.  For
# TrueType fonts, which are scalable fonts, small-caps is equivalent
# to using a font size of 'smaller', or about 83% of the current font
# size.
#
# The font.weight property has effectively 13 values: normal, bold,
# bolder, lighter, 100, 200, 300, ..., 900.  Normal is the same as
# 400, and bold is 700.  bolder and lighter are relative values with
# respect to the current weight.
#
# The font.stretch property has 11 values: ultra-condensed,
# extra-condensed, condensed, semi-condensed, normal, semi-expanded,
# expanded, extra-expanded, ultra-expanded, wider, and narrower.  This
# property is not currently implemented.
#
# The font.size property is the default font size for text, given in pts.
# 12pt is the standard value.
#
#font.family         : sans-serif
#font.style          : normal
#font.variant        : normal
#font.weight         : medium
#font.stretch        : normal
# note that font.size controls default text sizes.  To configure
# special text sizes tick labels, axes, labels, title, etc, see the rc
# settings for axes and ticks. Special text sizes can be defined
# relative to font.size, using the following values: xx-small, x-small,
# small, medium, large, x-large, xx-large, larger, or smaller
#font.size           : 12.0
#font.serif          : Bitstream Vera Serif, New Century Schoolbook, Century
Schoolbook L, Utopia, ITC Bookman, Bookman, Nimbus Roman No9 L, Times New
Roman, Times, Palatino, Charter, serif
#font.sans-serif     : Bitstream Vera Sans, Lucida Grande, Verdana, Geneva,
Lucid, Arial, Helvetica, Avant Garde, sans-serif
#font.cursive        : Apple Chancery, Textile, Zapf Chancery, Sand, cursive
#font.fantasy        : Comic Sans MS, Chicago, Charcoal, Impact, Western,
fantasy
#font.monospace      : Bitstream Vera Sans Mono, Andale Mono, Nimbus Mono L,
Courier New, Courier, Fixed, Terminal, monospace

I am just installing Windows 7 Pro and I am running into a problem with 
matplotlib.

When running e.g. barchart_demo.py I get an error that it can not find 
msvcp71.dll (the dll is in C:\Python25) and I see the following exception.

Traceback (most recent call last):
  File "barchart_demo.py", line 3, in <module>
    import matplotlib.pyplot as plt
  File "C:\Python25\Lib\site-packages\matplotlib\pyplot.py", line 6, in 
<module>
    from matplotlib.figure import Figure, figaspect
  File "C:\Python25\Lib\site-packages\matplotlib\figure.py", line 16, in 
<module>
    import artist

34, in <module>
    from matplotlib._path import affine_transform
ImportError: DLL load failed: Le module spcifi est introuvable.

Anyone seen this problem before on Win7?

BTW, I can run e.g. Boa (a wxPython based IDE).  I have no problem 
running my application which is wxPython based as long as I don't call 
anything which uses mpl.

Version info:

P.S.
Installed Python for all users - will try installing for me only

Is is possible to xalign rec2gtk columns?

I see the following line in the rec2gtk source:
 -> renderer.set_property('xalign', formatter.xalign)

but can't figure out how to pass this info to the func.

thx

Andre
