Call notes 29 Jan
by Jody Klymak Feb. 1, 2018

Feb. 1, 2018

Hi all, Call notes from Monday’s call. Cheers, Jody On call: Thomas, Eric, Ryan, Jody, Antony (later half) ## Documentation Thomas reported that there is a fund for a mini-workshop to scope out documentation changes. Plan was to use that to write a proposal to fund a book. - Eric expressed some reservations about a book, given the state of flux some parts of Matplotlib are in. - Jody noted that beyond the book, a shorter “getting started” guide on the webpage would still be desirable: ACTION: Jody to co-ordinate a couple of outline documents that could start outlining both of these projects before any meeting. There was also some discussion of online documentation technology: - Notebooks (via nbsphinx: https://nbsphinx.readthedocs.io) - hard to make PRs with. Diffs are a mess in GitHub. - Can’t use emacs (easily) - RST-based, with plot directive: - python authoring less than desirable - Sphinx-gallery based: - rst authoring less than desirable - sphinx gallery has very restricted ordering methods (file size and alphabetical) ## Release 2.2 Various Release-Critical PRs were looked at. -- Jody Klymak http://web.uvic.ca/~jklymak/

Article about matplotlib
by Nicolas Rougier Jan. 31, 2018

Jan. 31, 2018

Dear all, Ralf Gommers proposed a few days ago to start the writing of a long article about scipy and I wonder if there is some plan for matplotlib as well? I’m always citing John’s article but it would be nice to have a more up to date article (John’s article is 11 years old and matplotlib has evolved a lot since then). What do you think? Nicolas

2018-01-22 Call notes
by Ryan May Jan. 22, 2018

Jan. 22, 2018

On call: Myself, Anthony Lee, Eric Firing, Hannah, Jody Klymak, Ryan May - 2.2 priorities - 827 open issues tagged for this release, but these are mostly just carried forward from past milestones - Looked over release critical issues - 10033 (Axes sharing improvements) looks just about ready, needs some reviews - Punting 10216 (GDB gone on Travis) for now -- Anthony submitted 10291 for setting fault handler - Discussed 10210 (Qt Cairo): Who else is well-versed enough in Qt/Matplotlib to give a review - Need to get 9082 (geometry constraint manager) in and start kicking the tires on it - Discussed 10206 (units/converters and axes): decided it’s fine to not convert floats (numbers) passed in on axes that have converters - 8820 (pcolor of arrays of bools broken by numpy 1.13): Decided it’s numpy’s fault (changing behavior), not ours, so we're not going to go out of our way to fix this in matplotlib itself. There’s a reasonable workaround with `arr.astype(np.int)`. Ryan -- Ryan May

by Thomas Caswell Jan. 21, 2018

Jan. 21, 2018

Folks, Just tagged and pushed v2.1.2. Kicked off the mac/linux wheel building system, emailed Christoph, and put a PR into conda-forge for the new binaries. Will upload to pypi, updated the docs, and announce widely tomorrow night. Thanks to everyone who worked on this. On ward to 2.2. If people have time please help with review / triage of what is critical for 2.2 and what needs to be pushed to 3.0. Tom

CI: only run macosx on travis cron jobs / only branches
by Thomas Caswell Jan. 19, 2018

Jan. 19, 2018

Folks, https://blog.travis-ci.com/2017-09-22-macos-update Due to the travis OSX infrastructure not being able to keep up with demand they are going to limit concurrency of jobs that us osx. We have not seen many (any?) mac specific issues which I think means we are not getting much value out of running all of the PRs on OSX. We can probably get better linux concurrency (and help lighten the load on travis) if we do test on OSX less. Thoughts? Tom

Jan. 9, 2018

Folks, Is anyone interested in mentoring for GSoC this year? If we are going to take a student I would like at least 2 people other than me to volunteer to be a mentor per student. We need to get an initial response to numFOCUS in the next week or so. Tom

matplotilb 2.2 prep
by Thomas Caswell Jan. 8, 2018

Jan. 8, 2018

Folks, We are aiming to have a a 2.2.0rc1 around Jan 30. To that end please: - review and merge documentation PRs. Documentation changes can be merged by the first reviewer with the criteria "is it better than it was?" ( https://matplotlib.org/devel/coding_guide.html#pr-review-guidelines ) - Tag any important issues or PRs you are aware of as 'release critical' to ensure they get looked at. - move any issues and PRs you don't think are critical to 2.2 and won't be patched or reviewed in the next two-three weeks to the 3.0 milestone. If you have a commit bit just make the changes, if not please leave comments asking for the changes This will be the last minor release to support python 2.7 and will be the supported with (critical) bug fixes to 2020. The next release after 2.2 will be 3.0 targeted for ~July 2018. The only major API change will be dropping python2 support and will otherwise be a normal feature release. Tom

image tests fail locally on my OSX system
by Eric Firing Jan. 7, 2018

Jan. 7, 2018

On my normal environment, OSX 10.12.6 on a Macbook Pro Retina, I am getting multiple image test failures that are *not* just the usual freetype problems. (I am using 'export MPLLOCALFREETYPE=1' in my .bashrc.) The failures are most visible in the diffs of the spectrum plots. Is anyone else seeing this, or are others on OSX able to get all of the tests to pass? Eric
