Hello
I didn't get any coments, positive or negative about the MEP22 implementation.
Please take a look at https://github.com/matplotlib/matplotlib/pull/2759
Thanks

Tom,
 I can use the current master branch. But in contrast to the issue on 
Google App Engine, the computer I am working on can see the HOME-dir, so 
it will set it. But then it has no read/write permissions on it (when 
running as a batch job).
Thanks,
Elena

this is great news, thanks for posting this! Most/all of us will be at
SciPy and staying for the sprints, so if there's remaining design work that
this uncovers that's needed for future improvements, please make note of it
and we can discuss it face to face.

Hello everybody.
I just did a little update of the PR
https://github.com/matplotlib/matplotlib/pull/2759
This is the implementation of the MEP22.
I would like to have some feedback on this.
It is working and rebased so should merge cleanly.
There is an example in examples/user_interfaces/navigation.py that shows
the basic functionality of tools and toolbar reconfiguration and management.
Any comment is welcomed.
Thanks
Federico

Cross posted to IPython-dev and mpl-dev.
Over the Easter holidays I had a chance to take a look at implementing a
new matplotlib backend which would allow interactive figures inline in the
IPython notebook. It's something that has been on the radar for a couple of
years now, with work needed from both projects to make the functionality
possible, so I'm pleased to have been able to submit a PR (
https://github.com/matplotlib/matplotlib/pull/3008) to matplotlib which
finally adds the nbagg backend - the final piece of the jigsaw.
It still needs a lot of polish, both at its core and superficially, but I
think it is at a stage which gives me confidence that the IPython Comm <->
mpl WebAgg approach is going to work to a reasonable degree, and is now at
a stage where it is readily usable by anybody running IPython >=2.0.
I really just wanted to draw your attention to the PR (early testers
welcome), and say thanks to everybody who has been involved in getting to
this stage, particularly Michael Droettboom, Jason Grout and everyone
involved in the IPython Comm interface.
Cheers,
Phil

I think this is brought in from the parameters that were used to build 
Python itself. (The matplotlib build system doesn't explicitly add 
it). If you build matplotlib with a debug Python, you get a debug 
matplotlib, however. We could probably use a debug Python on Travis (in 
addition to the ones we already have) -- just a matter of installing the 
python-debug package and using the python-debug executable.

I don't think the Launchpad builds undefine that, unless Launchpad does it
for all builds by default.

I was prompted by
https://github.com/matplotlib/matplotlib/issues/2916
to run some static checkers on the C/C++ extension modules, and I was
going to submit some simple fixes as pull requests, including assertions
of some preconditions. I just realized that our build system sets the
-DNDEBUG compiler flag, which makes sense for release builds but could
hide problems in test builds.
Do any of our Travis, Launchpad, or other daily builds undefine NDEBUG?

Elena,
Is it possible for you to use the current master branch? We
definitely fixed this so that it would work with gae.

A great quote from a GitHub presentation at SciPy 2012: "We consider Pull
Requests to be the *start* of a conversation". Go ahead and make the pull
request. We can then review it, and you can make revisions to your branch
(the PR gets updated automatically as you push revisions up to it).
Cheers!

tcaswell suggested (https://github.com/matplotlib/matplotlib/issues/2972) I put together this example when I realized the difference between interpolation = 'none' and interpolation = 'nearest' in imshow(). The docstring for imshow() mentions this difference, but pictures are worth a thousand words.
Here is the summary of my changes:
https://github.com/Stretch97/matplotlib/compare/master...image-interpolation-example
This is my first contribution to matplotlib. I presume I wait until someone reviews my changes, and, if everything is ok, I submit a pull request.

Hi,
 I use matplotlib version 1.3.1.

Which version of matplotlib are you using? I am fairly certain we fixed
this problem for Google App Engine, which also does not have writable home
directories.

Hello,
 I run my code from a batch system, from where the $HOME-filesystem is not 
writable. In __init__.py in _get_home it finds ("~"), but then crashes 
because it doesn't have access to it. I tried to set XDG_CONFIG_HOME and 
MPLCONFIGDIR to circumvent this problem. But it still aborts. The only 
solution I have found so far is to hack the code and replace ("~") by my 
writable work-directory.
 Is there any other way to tell it which directory to use - without having 
to touch the actual code?
Thanks,
 Elena

Pinging on this issue now that we are about to include a new graph type in
mplot3d.
My thinking is that the determination of inclusion of this new
OptionalPackage should be made based on whether the regular tests package
was specified to be included *and* if the mpl_toolkits OptionalPackage was
specified to be included. Not exactly sure how that would get implemented,
but I am just getting my thoughts down on paper...
Cheers!

Hello everyone,
Just a quick reminder that the EuroScipy call for abstracts closes on the
14th: don't forget to submit your talk proposal! It is in four days only!
In short, EuroScipy is a cross-disciplinary gathering focused on the use
and development of the Python language in scientific research. This event
strives to bring together both users and developers of scientific tools, as
well as academic research and state of the art industry.
EuroSciPy 2014, the Seventh Annual Conference on Python in Science, takes
place in *Cambridge, UK on 27 - 30 August 2014*. The conference features
two days of tutorials followed by two days of scientific talks. The day
after the main conference, developer sprints will be organized on projects
of interest to attendees.
The topics presented at EuroSciPy are very diverse, with a focus on
advanced software engineering and original uses of Python and its
scientific libraries, either in theoretical or experimental research, from
both academia and the industry. The program includes keynotes, contributed
talks and posters.
Submissions for talks and posters are welcome on our website (
http://www.euroscipy.org/2014/). In your abstract, please provide details
on what Python tools are being employed, and how. The deadline for
submission is 14 April 2014.
Also until 14 April 2014, you can apply for a sprint session on 31 August
2014. See https://www.euroscipy.org/2014/calls/sprints/ for details.
Thanks,
N

Hi,
I've just uploaded binary wheels for OSX to pypi.
If you're on Python.org python, then this should work
pip install --upgrade pip # if you're not on latest pip already
pip install matplotlib
I mean - you should get the binary wheel for matplotlib.
If fact this wheel will also work for Mac system python or homebrew or
macports if suitably renamed, but I put this current one up now, for
testing.
Please do let me know if you have any problems.
(By the way - this should also work in a fresh install / virtualenv,
because numpy is already pip'ed up with wheels).
Cheers,
Matthew
