Philip:  It's not really a bug - but a "feature" of this particular 
example.  For the white space to disappear, the figure must have exactly 
the same aspect ratio as the map projection.  It's set that way in the 
example, but if you change but maximizing the window Basemap tries to 
maintain the aspect ratio of the map and leaves some whitespace.  To get 
rid of the whitespace, at the expensive of messing up the aspect ratio 
of the map when you resize, set fix_aspect=True when initializing the 
basemap instance (for basemap >= 0.99.4).

This looks like an issue with white space in the file path -- Windows 
can be weird about that.

That's why Python is usually installed directly into:

C:\python25

Rather than in "Program Files", though you're right, that's where it 
should be put.

what does that "Running" message come from -- it doesn't look like it's 
written to accommodate white space.

Jeff:

(I posted this same message via Nabble, but it doesn't seem to be 
getting through).

I have some further information: I just tried it again, and realized 
that if I use the original figure size and don't maximize the figure 
window, there are no white spaces. I don't see the white spaces unless I 
maximize the figure window. Maximizing the figure window should change 
the overall size of the image, but everything should scale together, so 
this is definitely a bug.

Phillip:  Do you see any white space between the unfolded faces of the 
cube on the cubed_sphere plot?  If not, then that command is working as 
expected.

-Jeff

Jeff: I am seeing fairly large horizontal white spaces between the unfolded
faces of the cube (see attached image).  Curiously, there are no vertical
white spaces.

This may be a dumb question, however i have been scratching my head trying
to figure out how to plot a 3 dimensional plot with with a colour map
different from the elevation(Z) parameter. 

 

An example of this done in Matlab would be 

 

[X,Y,Z] = peaks(30);

C=Z'% could be anything other than Z as long as it has the same dimensions

surf(X,Y,Z,C)

 

axis([-3 3 -3 3 -10 5])

 

 

Is this possible with matplotlib '0.99.1'

 

If so how do i go about doing this  is there some sample code?

Take a look at the table demo:

http://matplotlib.sourceforge.net/examples/pylab_examples/table_demo.html

Hello!

I am forced to use py version 2.3.3 (included in other software). I would
like to use matplotlib but can not find the version for py 2.3 on
sourceforge. I think it should be version 0.90.1?
Do you know how I can get hold of a copy of that version?

Thanks!

Best Ŕegards,
Olof Werneman

Hi,

Well when you plot, imshow or whatever is matplotlib related, the axes 
do scale *automatically*.
Why should it be different with quiver?

I do reproduce your error with axis('tight')

Just to be clear:
import numpy, matplotlib
works fine?

Alan Isaac

Please check if there are python26.dll or "Microsoft.VC90.CRT.manifest" 
files left in your Python directory. If yes, remove those files.

If that does not help, run Dependency Walker on python26.dll (should be 
in your system folder), enable "Full Paths" view and report the 
MSVCR90.DLL path. It should be 
<c:\windows\winsxs\x86_microsoft.vc90.crt_1fc8b3b9a1e18e3b_9.0.30729.4926_none_508ed732bcbc0e5a\MSVCR90.DLL>

I assume the missing DWMAPI.DLL and EFSADU.DLL dependencies come from 
IE7/8 and can be ignored.

I've attached patches against Python 2.5 and 2.6 to that bug.  Neither 
is significantly different from the original patch.

http://bugs.python.org/issue1222585

Once doing that, you'll also need to make the following change to 
matplotlib so that the correct C++ runtime libraries are used.  Once I 
figure out how to correctly detect the compiler being used, I'll make 
this change in the matplotlib SVN repository.  (This is non-trivial, 
since distutils doesn't have a Sun compiler specialization -- it uses 
the "generic" Unix compiler support for both gcc and Sun Studio.)

Christoph, I couldn't get it to work after this download either. Same problem as before. 

After that, I tried the following:
1. Upgraded to XP Service Pack 3.

2. Uninstalled Python 2.6 and all related packages.
3. Reinstalled Python 2.6.4 with "Install for all users" set.
4. Reinstalled Numpy 1.3.0.
5. Reinstalled Matplotlib 0.99.1.
(all installations from binaries from sourceforge)
That didn't help either. 

Is there any better debug information I can provide (trace or something)? The output of "python -v" seems rather insufficient.

Thanks,
Dilip.

I think the LaTeX root might be a good one. Set your usetex to True in rcParams and make a separate file (table.tex). 
Then use:
>>> figure.figtext(fig_x, fig_y, r'\input{table.tex}')

I haven't tested this, but it seems like it should work. I'd be curious to hear how it goes.

Hi Xavier (cc list),

It may be a bug, however I do not know what the default behaviour 'should' be. You could do:

lims = [-4, 4, -4, 4]
axis(lims)

after calling quiver to see the whole arrow. I did notice that calling

axis('tight')

threw the following error

/Users/Damon/python/lib/matplotlib/axes.py:2038: UserWarning: Attempting to set identical xmin==xmax results in singular transformations; automatically expanding.  xmin=1.0, xmax=1.0
  warnings.warn('Attempting to set identical xmin==xmax results in singular transformations; automatically expanding.  xmin=%s, xmax=%s'%(xmin, xmax))
/Users/Damon/python/lib/matplotlib/axes.py:2212: UserWarning: Attempting to set identical ymin==ymax results in singular transformations; automatically expanding.  ymin=1.0, ymax=1.0
  warnings.warn('Attempting to set identical ymin==ymax results in singular transformations; automatically expanding.  ymin=%s, ymax=%s'%(ymin, ymax))

is this correct, or is it a bug? I'm using "ipython -pylab" with the MacOSX backend. I was expecting axis('tight') would scale the axes so I could see the whole arrow.

Hi,

I'm trying to add some notes in a table to a plot, and I don't know how to
use the "'matplotlib.pyplot.table" command.
I really don't want to use ax.text(...) with different x,y values...

Any suggestions? Example to table command, insert LaTex tables, Etc.

Thanks,
Sahar

I did in a similar way
l1 = plot(datax, datay, label='my favorite label for squares',
marker='s', color='black', mfc='white', mec='black')
plot(datax, daty, label='my favorite label for squares', marker='s', 
color='black', mfc='red', mec='black')

I plot the data 2 times and them in the legend only add the firs line 
with white markers

legend([l1],[label])

But I think this functionality should not be difficult to implement
directly and maybe someone has done it.

This is a years-old known bug in distutils (which it looks like you've 
already commented on...).  I've looked at it many times over those 
years, and it's really very difficult to fix from outside without 
terrible monkey-patching hacks that are certain to break on as many 
systems as they fix.  We just may be forced to deal with it at this 
point, though.  (FWIW, we run Solaris here, too, but we build matplotlib 
on gcc).  I'll comment on that bug as well and see if we can get some 
movement on it.

In the meantime, I'll investigate whether the scons work by David 
Cournapeau resolves this problem.  See here:

Phillip:  Do you see any white space between the unfolded faces of the 
cube on the cubed_sphere plot?  If not, then that command is working as 
expected.

IMO I don't think the traffic level on either pure mpl or basemap 
warrants a split.

Try installing the Microsoft Visual C++ 2008 Redistributable Package (x86)
<http://www.microsoft.com/downloadS/details.aspx?familyid=9B2DA534-3E03-4391-8A4D-074B9F2BC1BF&displaylang=en>.
This is usually installed during the installation of Python in the 
"Install For All Users" mode.

Hi, all.

I am unable to import matplotlib.pylab. 

When I run the following command:
python -c "import matplotlib.pylab"
the application crashes with a windows error message.

Running with the -v option shows that the application crashes at the following stage:
import matplotlib.transforms

>From previous posts on this mailing list, others have encountered similar (but perhaps not quite the same?) problems. I followed some of the advice and downloaded the dependency walker software from http://www.dependencywalker.com. Dependency Walker says that the following DLLs are missing for _path.pyd:
MSVCP90.DLL, MSVCR90.DLL, DWMAPI.DLL, EFSADU.DLL.

(Indeed I tried many .pyd files from C:\Python26\Lib\site-packages\matplotlib and all of them gave similar error messages.)

Any idea how I can get these DLLs (they aren't in C:\Windows\System32) or, indeed, whether this is the actual solution to the problem?

I have the following versions:

Windows XP Service Pack 2
Python 2.6
Matplotlib 0.99.1

Python and Matplotlib were binaries downloaded from sourceforge.net.

Thanks,
Dilip.
