EuroScipy 2015, the annual conference on Python in science will take place in
Cambridge, UK on 26-30 August 2015. The conference features two days of
tutorials followed by two days of scientific talks & posters and an extra day
dedicated to developer sprints. It is the major event in Europe in the field of
technical/scientific computing within the Python ecosystem. Data scientists,
analysts, quants, PhD's, scientists and students from more than 20 countries
attended the conference last year.

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.

Submissions for posters, talks & tutorials (beginner and advanced) are welcome
on our website at http://www.euroscipy.org/2015/ Sprint proposals should be
addressed directly to the organisation at eur...@py...

The branch 1.4.x was the branch for bug fixes that would eventually turn
into the _next_ 1.4 series release.  We do not plan on doing a 1.4.4 so the
1.4.x branch no longer is needed.  The commit used for the releases are
tagged (ex v1.4.3).  The v1.4.3-doc branch is so that we can correct any
documentation issues and re-build the website if needed.

I am in favor of doing in in PR comments so we can to line comments.

So it seems I was using the old branch (now deleted?) v1.4.x rather than 
v1.4.3-doc, which does have the commit for the fix in question. I was 
naively assuming that v1.4.x was always the latest release in the v1.4 
series.

False alarm. Sorry.

Great ! Thanks for setting this up. One comment, it would be great to have a README.rst in the directory to have abstract of all MEPS at once in github (I can make a PR).


I've started working on MEP28 (https://github.com/rougier/matplotlib/blob/MEP28/doc/devel/MEP/MEP28.rst). I intend to make a PR once it is a bit more polished or should I make a PR right now to initiate the discussion on the PR ? (It is not clear to me if the preferred medium for discussion is the mailing list or the PR comments).

I have made some progress with this, I found a incomplete recipe written by
some body. So the next step for me is to read the python-for-android's
distribute.sh file so I can get a better understanding of the template they
provide. I am slow though because less time and will power.

The MEP tree has been moved into the main repo
https://github.com/matplotlib/matplotlib/tree/master/doc/devel/MEP

I am pretty excited about this feature.

I don't remember if this got mentioned upthread, but this ties in with
https://github.com/matplotlib/matplotlib/issues/1109 as a nice way to set
up all of the constraints.

Sorry this never got a response.  I also have no idea where to start, but
mpl depends an numpy (which has significant c code) and a number of c
extensions internally (Agg for rasterization, freetype for font rendering).

I would suggest starting with figuring out how to compile numpy as it is
required and I suspect simpler to compile.

The commit that fixes that
https://github.com/matplotlib/matplotlib/commit/40720ef9fb5de75d908d0ce433d5c3bb8902884f
should be in 1.4.1 an onward.  Exactly which version are you using?

There will be no 1.4.4.

Is there any possibility of back-porting the fix to the boxplot 
positions to v1.4.x? This would be ticket #3563. I had thought that this 
was fixed in 1.4, but it seems to be there again. v1.5-devel (where the 
boxplot works fine) is not-very-usable for me due to the GTK idle bug.

Thanks,

M

Kelvin,

Thank you for your work. Would it be possible for you to open a pull
request on git hub with these changes (that is where we so almost all of
our code review recently and is hooked in to a continuous integration
service).

I have not looked at the diff yet (still on my phone), but from looking at
the file list I am a bit concerned. The backends have a good number of
imports that are there for compatibility reasons.

This might also conflict with the mep27 related pr #4143.

There is also an open pr working on the wx backend that this may conflict
with (#3421).

Tom

First ever patch submission. Here I propose cleaning up some unused variables
and imports.

Kelvin Li (2):
  remove unused variable "cmd_split"
  backends: remove unnecessary import statements

Yes, this was discovered recently in connection to changes in how idle
events were handled. I don't recall if there was an issue created for it,
though.

Hi All,

I don't have time at the moment to submit a ticket, but I thought I'd 
see if anyone else is having this problem:

With latest master on 1.5-devel using GTKAgg backend, (and in ipython 
3.0.0-dev, python 2.7.8, MacOSX 10.9.5) if I do figure() and nothing 
else, and then run 'top', I see Python running 100% CPU for the process. 
Closing the figure stops Python hogging the CPU.

With latest 1.4.x, I do not see it.

I guess you could just load some test patterns into any commercial software
graphics or design package that supports color gamut alarms, and try some
typical printer settings to make sure that the candidate color maps aren't
excessively blowing the boundaries. I'm not advocating that the default
color map needs to be perfectly reproducible in print, but it might be
worth sanity checking this; it might mean avoiding bright greens and
yellows for example. I see that PIL/pillow contains littlecms support and I
see its ImageCms.py file contains a GAMUTCHECK flag, so it might be
possible to use that, along with some common icc profiles to automate the
checking, or build it into an optimiser as a constraint.

"sunset" has a connotation of things ending. Howabout "sunrise"?

How would you go about doing this in practice? Is it even possible to
choose a subset of sRGB space and have printers take advantage of that when
doing gamut mapping? (I guess I always assumed that printer gamut mapping
applied to an RGB image would map all of RGB into their gamut, so there
would be no advantage to restricting oneself go a subspace. But maybe I'm
wrong -- color management is pretty fancy these days.)

Just wondering whether anyone has suggested checking candidate colormaps
against typical printer color gamuts?

I checked with my red-green color-blind colleague, Niklas Schneider, and 
his evaluation is attached.

Eric

I like it, but perhaps we should condense it to one word for ease of 
typing, how about "Redgauntlet"?  It kind of feels appropriate (for 
those who need an explanation of why, see 
https://www.youtube.com/watch?v=_guKhYVr5vA).

On the colormap itself, it looks good apart from the fade into blue, my 
eyes on this laptop monitor see a sharp gradient around 0.2 compared 
with the more gradual gradient at the other end.  Also I see constant 
colour between 0 and 0.1, and between 0.9 and 1, with less change 
between 0.8 to 0.9 then 0.1 and 0.2.  Not sure if one causes an optical 
illusion in the other or not.

Finally a bit confused as to what all the lines mean, any chance of some 
annotation?  Also I would find it helpful to see a version without the 
big red line and what it looks like in practice (see the doc for the 
test script).

Best,
OceanWolf

That is nice. The blue is a bit heavy, but that might be my display. Now,
how should we order it by default? I am used to thinking of blues as lower
values, and reds as higher. The yellow at the end throws me off a bit,
because I would think of it as a "weaker" color. Maybe if it was more
gold-like?

We should also start thinking of a snazzy name. BlRdYe probably won't cut
it.
