[Matplotlib-users] Docathon : focus on documentation on your favorite opensource project!

2017-03-01 Thread Nelle Varoquaux
Hi everyone,

Apologies for cross-posting : this event might be of interest to some of
the projects of the scientific Python community. We are trying to encourage
FOSS developers to focus on documentation for a week instead of fixing bugs
or implementing cool features!

Here are more informations about the project.

Thanks,
Nelle
Sign up your project for the docathon!

The Docathon is happening next week! We’ve already got several projects
signed up to participate in improving their documentation during the week.
We’ve put together a nifty project board
 so that we
can keep track of everybody’s progress during the week! If you sign up as a
project , we’ll post your
documentation commit stats like this:

How can I join in?
We want you to improve your documentation, wherever you are. To that
extent, we’ll keep track of project activity regardless of its location. If
you’d like to work with a group of people, here are a few specifics:

To kick off the docathon we’ll have a morning of tutorials on Monday, March
6th. These will cover particular tools and techniques for building great
documentation. If you’re at Berkeley then you can sign up here
.
This will also be live-streamed on Youtube, so you can watch from wherever
you are!

We’ll also have some working groups meeting periodically in cities around
the country. If you’d like to join in with these groups, click one of these
links:


   -

   New York City - Signup
    / Agenda
   
   -

   Berkeley - Signup
   

   / Agenda 
   -

   Seattle - Signup  / Agenda
   


You can also work remotely if you like, we will coordinate people via
email/GitHub, too.

Wherever you are, don’t forget to sign up as a participant
 so we can give some pointers on
how to contribute. Or, suggest a project
 to work on and we’ll keep track of
its activity on our projects page
.

Contact
If you have any questions, check out the Docathon website
 or open an issue on our GitHub repo
.

Please feel free to forward this email to anyone who may be interested.
We'd love for other institutions/groups to get involved.

[Matplotlib-users] Announcing: Docathon, week of 6 March 2017

2017-02-16 Thread Nelle Varoquaux
Hi everyone,

As some of you already know, some of us are involved in the organization of
a docathon. Several of us will be meeting up to sprint on documentation or
documentation-related projects at Berkeley, New York and Seattle.

If you are interested in joining us, either remotely or on campus, don't
hesitate to join!

Cheers,
Nelle

*What's a Docathon?*
It's a week-long sprint where we focus our efforts on improving the state
of documentation in the open-source and open-science world. This means
writing better documentation, building tools, and sharing skills.

*Who’s this for?*
Anyone who is interested in improving the understandability, accessibility,
and clarity of software! This might mean developers with a particular
project, or individuals who would like to contribute to a project. You
don’t need to use a specific language (though there will be many Python and
R developers) and you don’t need to be a core developer in order to help
out.

*Where can I sign up?*
Check out the *Docathon website* . You
can sign up as a *participant*
, *suggest
a project*  to work on, or sign up *to
host your own*  remote
Docathon wherever you like. You don’t have to use a specific language -
we’ll be as accommodating as possible!

*When is the Docathon?*
The Docathon will be held *March 6 through March 10*. For those coming to
BIDS at UC Berkeley, on the first day we'll have tutorials about
documentation and demos of documentation tools, followed by a few hours of
hacking. During the middle of the week, we'll set aside a few hours each
afternoon for hacking as a group at BIDS. On the last day, we'll have a
wrap-up event to show off what everybody worked on.

*Where will the Docathon take place?*
There are a *few docathons being held simultaneously*
, each with their own
schedule. At Berkeley we'll have a physical presence at BIDS over the week,
and we encourage you to show up for the hours we set aside for doc hacking.
However, it is totally fine to work remotely; we will coordinate people via
email/GitHub, too.

*Where can I get more information?*
Check out an updated schedule, list of tutorials, and more information at
our website here: *bids.github.io/docathon* 
.

*Contact*
If you have any questions, open an issue on our *GitHub repo*
. We look forward to hearing from you!

Please feel free to forward this email to anyone who may be interested.
We'd love for other institutions/groups to get involved.

 Hello all,

 We are pleased to announce the release of matplotlib v1.4.3!

 Wheels, windows binaries and the source tarball are available through both
 source-forge [1]  and pypi (via pip).  Additionally the source is available
 tarball is available from github [2] and mac-wheels from
 http://wheels.scikit-image.org/.

 This is the last planned bug-fix release in the 1.4 series.

 Many bugs are fixed including:

 fixing drawing of edge-only markers in AGG
 fix run-away memory usage when using %inline or saving with a tight bounding
 box with QuadMesh artists
 improvements to wx and tk gui backends

 Additionally the webagg and nbagg backends were brought closer to
 feature parity with the desktop backends with the addition of keyboard
 and scroll events thanks to Steven Silvester.

 The next planned release will be based on the 1.4.x series but will change
 the default colors and be tagged as version v2.0. The target release date is
 in the next month or two.

 The next feature release will be v2.1 targeted for around SciPy in July.

 3) usually never, except at the beginning of a sentence and in titles

 5) usually capitalize like a proper noun except in code examples

Re: [Matplotlib-users] ANN: matplotlib 1.3.1

2013-10-18 Thread Nelle Varoquaux
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

  I'm pleased to announce the release of matplotlib version 1.3.1.  This is a 
 bugfix release.

 It may be downloaded from here, or installed through the package manager of 
 your choice (when available):
 http://matplotlib.org/downloads

 The changelog is copied below:

 New in 1.3.1
 

 1.3.1 is a bugfix release, primarily dealing with improved setup and
 handling of dependencies, and correcting and enhancing the
 documentation.

 The following changes were made in 1.3.1 since 1.3.0.

 Enhancements
 

 - Added a context manager for creating multi-page pdfs (see
`matplotlib.backends.backend_pdf.PdfPages`).

 - The WebAgg backend should no have lower latency over heterogeneous
Internet connections.

 Bug fixes
 `

 - Histogram plots now contain the endline.

 - Fixes to the Molleweide projection.

 - Handling recent fonts from Microsoft and Macintosh-style fonts with
non-ascii metadata is improved.

 - Hatching of fill between plots now works correctly in the PDF
backend.

 - Tight bounding box support now works in the PGF backend.

 - Transparent figures now display correctly in the Qt4Agg backend.

 - Drawing lines from one subplot to another now works.

 - Unit handling on masked arrays has been improved.

 Setup and dependencies
 ``

 - Now works with any version of pyparsing 1.5.6 or later, without displaying
hundreds of warnings.

 - Now works with 64-bit versions of Ghostscript on MS-Windows.

 - When installing from source into an environment without Numpy, Numpy
will first be downloaded and built and then used to build
matplotlib.

 - Externally installed backends are now always imported using a
fully-qualified path to the module.

 - Works with newer version of wxPython.

 - Can now build with a PyCXX installed globally on the system from source.

 - Better detection of Gtk3 dependencies.

 Testing
 ```

 - Tests should now work in non-English locales.

 - PEP8 conformance tests now report on locations of issues.

 Mike

 My source is an image, so technically f:R^2 - R.  Specifically I am
 using depth maps or (range image) what to visualise the
 surfaces/normals.   I was  planing on plotting the image as surface
 (hadn't work out how yet) and overlay the normal vectors.  I think a 2D
 quiver plot on top of a contour plot may provide a useful
 visualisation/interpretation of the process.


You always have the solution to install mayavi, a 3D plotting library. The
API resemble maptlotlib's and it supports 3D quiver plots.

 Thanks for the idea.

  I put the original feature request in, and I think it would be useful,
  but often I still find it easier to process two dimensional
  information.
 
  N.B.  The above will only work for *functions* f:R^2 - R.  To
  clarify, a sphere cannot be expressed this way, because the resulting
  mapping would be multivalued.  Using this method, two distinct surface
  normals may have the same colour.
 
  Hope that makes sense.

Re: [Matplotlib-users] Lots of failing tests raising KnownFailureTest

2012-11-19 Thread Nelle Varoquaux
Hello,

Hi

 When running the testsuite for matplotlib-1.2.0 i.e.

 $ nosetests -exe matplotlib


This is not the correct way to run the tests. You need to run them using:

python tests.py

I currently have a PR that indicates that in the README


 I'm getting a lot of errors of the form:


 Does the same thing happen with the following command:

 python -c import matplotlib; matplotlib.test()


That's another way of running the tests on matplotlib.



 I haven't used nosetest before, so I have no clue if it does anything
 different than we expect.


KnownFailure is not a default nosetest packages. Hence, we have to load
it manually when running the tests.

Hence, all the tests that are known to fail actually fail, so that what we
expect.

Cheers,
N

Re: [Matplotlib-users] Matplotlib produced plots in academic journal articles

2012-10-05 Thread Nelle Varoquaux

 I think including a gallery of published examples would be great, however,
 there will be some serious challenges with regards to copyright. It would
 be great to show MPL being used in high impact journals (which it is), but
 getting permission from them to show the plots on the MPL website may
 require some paperwork. So, a list of citations might be a good place to
 start. Here's mine: http://jeb.biologists.org/content/215/11/1783.full


I just came back from a bioinformatics workshop: I was suprised by the
amound of people using matplotlib to display results.
I think it wouldn't be too hard to gather images and published them on
matplotlib's website if the authors are OK with it. Also, in cancer
research, publications and/or plots are often available publicly.

I don't think citations would be as efficient: I personnally wouldn't
bother looking at those.
Here is an example on circos' website of how they advertise the use of
their plotting library in research: http://circos.ca/intro/published_images/

  Gökhan

 Short version:
 I think this is a good idea.

 Long version:
 I think a 'Who uses matplotlib?' section in the website would provide
 good solid academic backing, too. I know the Met Office
 (PHIL) and some of the guys in the PECOS group at ICES
 use it.

 Actual papers is great, but probably rather drab? I think if we want
 to show it off, we should include sample images from citations, rather
 than just citations. After all, how many people are going to chase a
 citation to see sample output when we have a gallery section? Better
 still would be to have an 'academic gallery' section. Perhaps this
 could be part of the gallery re-work someone was going to do (was it
 Tony? I forget).

 I don't know. I think the idea is good, but I think there needs to be
 some thought and consensus regarding the *best* way to get people to
 *visually* judge matplotlib's capabilities in the academic realm.

 This is just my two.

 This is not true. A lot of articles are unavailable to certain
 institutions due to a lack of subscription. A major sticking point.

 Am I wrong in thinking that journals copyright the final product?
 Thus, it would be up to the author(s) to decide whether or not to
 'donate' a figure for a gallery.


I think it depends on the journal, and on the agreement. I think in most
journals you/your institute can pay to have your paper publicly available.

I wouldn't be shocked if a requirement to be in the gallery would be to
donate a figure.



  provide context to the use of plots rather that extracting figures and
  putting them separately (dealing with copyright issues and such) on an
  alternative gallery page. The figures you linked look shinny but not much
  practical use in my field.


I was just showing an example of a gallery of published figures. It is much
easier to go through a gallery, to quickly see what a library is capable
of, than clicking on links to articles, that may often be of closed access.




 Point taken on the context argument. I'll take that. To resolve it,
 make the figure/html image link to the underlying publication?

When you build a shared library yourself, you always need to set the
variable LD_LIBRARY_PATH. This is independant from the compilation. At
runtime, the program merely tries to load the library if it has not been
loaded previously.

Usually, to avoid setting manually the path to the library, one adds this
to its bashrc/zshrc.

I hope this helps.

 Have you set up pkg-config for your build of libpng? If you can't do
 that for some reason, you can edit basedirlist in setup.cfg.

Re: [Matplotlib-users] How to change the textsize inside a legend?

2012-08-31 Thread Nelle Varoquaux
Hello Fabien,

There is a font size attribute to ``legend``. Here is the description from
the docstring:

  *fontsize*: [ size in points | 'xx-small' | 'x-small' |
  'small' | 'medium' | 'large' | 'x-large' | 'xx-large' ]
Set the font size.  May be either a size string, relative to
the default font size, or an absolute font size in points. This
argument is only used if prop is not specified.

Cheers,
Nelle
