setupext.py.  CXX.check() contains

          return self._check_for_pkg_config('PyCXX', 'CXX/Extensions.hxx',
min_version='6.2.4')

which requires version 6.2.4 or later of CXX.  Nils has 6.2.3 and so this
check should fail and matplotlib should fall back to using the local copy
of CXX.  SetupPackage._check_for_pkg_config() does check min_version if CXX
is installed using pkg-config, but if it is not then min_version is ignored
as the function raises a CheckFailed error before min_version is
considered.  CXX.check() catches this error and uses the system-installed
CXX regardless of its version.

To check the CXX version we probably need to look in CXX/Version.hxx.  I am
not sure how to proceed; do you have any ideas Mike?

Nils, as a stopgap you could either remove your python-cxx and
python-cxx-devel rpms if you don't need them for anything else, or upgrade
them to 6.2.4.  There is a 6.2.4 on rpm.pbone.net even though there isn't
one on packman.links2linux.de.

Ian

I installed OS X Mavericks a few days ago and I am running Mapllotlib Version 1.3.1.
Everything works fine except that I get a warning every time i use the pyplot.show() command.

here is what it looks like:
----
Python[27325] <Error>: The function `CGContextErase' is obsolete and will be removed in an upcoming update. Unfortunately, this application, or a library it uses, is using this obsolete function, and is thereby contributing to an overall degradation of system performance.
---

I thought I should ask if this is serious and also if something can be done about it.

Best,
Bedartha

The problem persists in master.

What are those arrows for if not for cycling through figures? Is this
really the only way to accomplish what the OP wants here? By writing
an event handler?

Hello,

I have stereographic projection of the pole. I need to indicate the
directions like north,south,east, west, north-east, north-west and so on.
Is there any way to do so?

Thanks

Sorry about that.  I just addressed that this morning.

That's my bad.  I've updated the PyPI entry.

I just realized that I replied to this off-list. Sending back out to the
entire list. (Sorry for the duplicate e-mail Christoph!)

No, your first assumption was correct. "figsize" refers to the size of the
whole figure.

What I meant to do in that example was abuse the fact that matplotlib will
happily add things beyond the figure boundaries. You can then abuse the
"bbox_inches" kwarg to savefig to show everything, while keeping the size
of the "data area" between the axes boundaries the same as the figsize.

My example there is actually completely wrong.  I meant to do this:

import numpy as np
import matplotlib.pyplot as plt

dpi = 80
data = np.random.random((100, 100))

height, width = np.array(data.shape, dtype=float) / dpi

fig = plt.figure(figsize=(width, height), dpi=dpi)
ax = fig.add_axes([0, 0, 1, 1])

ax.imshow(data, interpolation='none')
fig.savefig('test.png', bbox_inches='tight')

At any rate, I'm not quite sure if that's actually what you wanted, but
it's a useful trick in cases like this.

This has been requested before, and it probably wouldn't be that difficult
to implement. If you want to take a crack at it, try making orthographic
versions of the functions in mpl_toolkits/mplot3d/proj3d.py. The tricky
part will be getting the right projection hooked up, but for now, you could
just override the existing functions.

Cheers!

Thanks for your suggestion. I needed to do this, but it solved a different problem.

The compilation problem above appears to be caused by settings of CPPFLAGS and/or LDFLAGS that pointed to my macports installation. Unsetting these before compilation solved the compiler error.

However, the links you mentioned were also necessary. Without them matplotlib links against the system Tcl/TK in /System/Library, whereas Python's tkinter is linked to the one in /Library. This gives a clash at runtime:

"Class TKApplication is implemented in both /Library/Frameworks/Tk.framework/Versions/8.5/Tk and /System/Library/Frameworks/Tk.framework/Versions/8.5/Tk. One of the two will be used. Which one is undefined."

and a couple more of these. Thereafter it crashes. The links in /Developer/SDKs/MacOSX10.6.sdk/Library/Frameworks to the frameworks in /Library make the thing consistent.

I want to create a 3d plot with matplotlib. I've gotten it to work, and can
control the view (camera) angles, but I don't want any foreshortening /
perspective. Is there a way to just have a plain orthographic projection
instead?

Hello,
Congratulations for this new minor release !
Someone mentionned on python-list that it's not available on pypi. I
checked, and indeed it isn't.
Should we upload it there?
Thanks,
N

Hi, all,
It didn't work for me with mpl 1.3 but it does with 1.3.1 (openSuse 12.3,
python 2.7.3, 64-bit).

To install 1.3.1, I had to use the archive from SourceForge directly since
only 1.3.0 is listed on pypi (I used pip) -- could that be the source of
this issue for you?

Regards,
Paulo Meira

For what it is worth I see behaviour identical to Neal. I'm using a
development version of matplotlib (v1.4.x, sorry I don't know the hash of
the installed version) on 64-bit Linux (Ubuntu 12.04) and Python 2.7.3.
That probably doesn't help much, except to show that this is not specific
to just Neal!

This is really puzzling.  What version of matplotlib are you running, 
what platform, and what version of Python?  Your example works just fine 
for me.

And without plt.xkcd() the tex is rendered correctly

No.  Also tried removing .matplotlibrc (in ~/.matplotlib).

Hello,

The script pasted below plots a square array.  The (very small) output
PDF is attached to this posting.  For reasons I do not understand,
there's a fine additional border immediately at the top and bottom of
the array.

If the commented-out line of code is removed, the strange border
disappears.

Now you will ask, why do I create the figure in this way and don't
simply use the commented-out line?  The answer is that this script is a
simplified version of the function "map" from
http://git.kwant-project.org/kwant/tree/kwant/plotter.py?id=v1.0.0
There, we need to create a figure also when pyplot has not been
imported.

If we would import matplotlib.pyplot, the user of our package could not
freely choose the matplotlib backend himself.

Thanks,
Christoph

Puzzling.  Do you have a matplotlibrc in the current working directory?

This example shows the error on my platform - the xlabel is not rendered with 
tex but instead the '$' are printed:

import numpy as np
import matplotlib.pyplot as plt
plt.xkcd()

fig = fig = plt.figure() 
ax = fig.add_subplot(111)
plt.plot (np.arange (10), 2*np.arange(10))
ax.set_xlabel ('$E_{s}/N_{0}$')
plt.show()

Strange.  I don't have anything about usetex in the script, or in my 
.matplotlibrc - all it has is:

backend : Qt4Agg
mathtext.fontset: stix

Thanks.  Setting figsize is indeed the way to achieve (almost) what I
wanted.  My other followup in this thread describes the remaining issue.

Joe, thank you very much for your reply.  So the "figsize" of a
matplotlib plot is the physical size of the region between the axes
where the data is shown?  If this is indeed the case, as it seems, then
achieving (almost) what I wanted is as easy as setting a figsize with
the proper aspect ratio, like in your example.

Before your reply, I believed that "figure size" in matplotlib refers to
the size of the whole figure (including axes, axis labels, and borders),
as "figure" in matplotlib seems to be a name for instances of
matplotlib.figure.Figure which are the whole thing.

I said "almost" in the first paragraph as it would be nice if there was
a way to create figures that have a given total width (after cropping)
at a given font size.  The reason is this: In many scientific journals
(for example Physical Review), figures are scaled to have the same width
as a column of text.

If I prepare a bunch of figures with the same width "within the axes"
and consistent font sizes and line widths, the resulting figures will
typically have somewhat different total widths.  After scaling the
figures to the same width, the font sizes and line widths will differ
slightly from figure to figure.

The built-in mathtext support does. (I can put "xkcd()" at the top of 
the mathtext_demo.py example and all is well).

It does not work when |text.usetex| is True (when using external TeX). 
But in that case, it should have thrown an exception:

|Traceback (most recent call last):
   File "mathtext_demo.py", line 9, in <module>
     xkcd()
   File "/home/mdboom/python/lib/python2.7/site-packages/matplotlib-1.4.x-py2.7-linux-x86_64.egg/matplotlib/pyplot.py", line 293, in xkcd
     "xkcd mode is not compatible with text.usetex = True")
RuntimeError: xkcd mode is not compatible with text.usetex = True|
