https issues with github pages
by Thomas Caswell April 1, 2017

April 1, 2017

See https://github.com/matplotlib/matplotlib/issues/8302 The https version of urls has started to appear in google search results. I have reached out to github support to see if there is anything they can do to ameliorate this. I personally know very little about how all of this works under the hood, is there anyone on here who does and will volunteer to take point on resolving this? Tom

Confusion about draw_artist
by Matthew Brett April 1, 2017

April 1, 2017

Hi, We're using 'draw_artist' in an image viewer, and I just found that our viewer is crashing using the macosx backend. Here's a minimal example: import matplotlib matplotlib.use('macosx') import matplotlib.pyplot as plt fig, ax = plt.subplots(1, 1) im = plt.imshow([[1, 2], [3, 4]]) fig.canvas.draw() ax.draw_artist(im) This generates: Traceback (most recent call last): File "draw_artist.py", line 8, in <module> ax.draw_artist(im) File "/Users/mb312/dev_trees/matplotlib/lib/matplotlib/axes/_base.py", line 2423, in draw_artist raise AttributeError(msg) AttributeError: draw_artist can only be used after an initial draw which caches the render for the macosx backend, and works correctly for the tkagg backend. I can't see any way to cache the renderer here - could someone give me a pointer? Cheers, Matthew

I'd suggest looking through the geometry manager labels ( https://github.com/matplotlib/matplotlib/issues?q=is%3Aopen+is%3Aissue+labe…), but hopefully a developer more familiar with layout manager tasks can chime in.

03/27/2017 phone call notes
by Antony Lee March 27, 2017

March 27, 2017

Hi all, On the call were efiring and myself. - efiring opened #8381 to fix various problems with minor ticks. We agreed that the separation between major and minor tickers is problematic because the minor ticker needs to "guess" where the major ticks are going to be in order to decide where the minor ticks are (and, note that the major ticker may well be a user-defined class with arbitrary behavior); thus, a new architecture where a single ticker handles both major and minor ticks may be more sensible. If we go that route, it may be worth also looking at a redesign of the Formatter class (#5804), so that we expose everything that's needed by the formatters too. - We discussed a potential new mechanism for fixing the artist order in legend, see https://github.com/matplotlib/matplotlib/issues/8389 - We discussed fixing the semantics of columns vs rows in boxplot/hist, see https://github.com/matplotlib/matplotlib/issues/8092#issuecomment-289566032.

SciPy 2017 Tutorial Proposals
by Benjamin Root March 27, 2017

March 27, 2017

Hi all! I am a co-chair of the tutorial committee for this year's SciPy conference again. As usual, we tend to have someone give a basics-level tutorial for matplotlib. There has been some calls to also have a more advanced tutorial of some sort as well. I would like to start putting our heads together and see what sort of proposals we can put together for this year. Proposals for tutorials are due March 22nd. Cheers! Ben Root

clearing 'request changes' review
by Thomas Caswell March 24, 2017

March 24, 2017

Folks, I propose the following: - if you would be happy with any other dev clearing the review leave a note saying so explicitly - the default (no note) is to not dismiss other devs reviews, but if there is otherwise consensus and the 'request changes' reviewer is non-responsive, it may be cleared (use your judgement folks!) - if you want to block merging until you re-review it, leave a note saying so.

There's a FuncNorm PR that touches on a lot of the same issues...might be worth checking out.

GSoC 2017: Layout Manager
by Kanchana Ranasinghe March 21, 2017

March 21, 2017

Hi I'm an electronics and telecommunications engineering student from University Moratuwa, Sri Lanka. I am interested in the matplotlib project Layout Manager. I have done some work with python and am quite familiar with python and regular libraries like numpy, scipy. I have also been involved in some machine learning and computer vision related research at university, so I am familiar with contraint solvers as well as most common AI related algorithms. I am going through the Cassowary library for now. I couldn't find the issues on the mailing list related to this. Could you share with me the detailed expectations of this project? Also do let me know how else I can get involved for now. Thank you. With Regards Kanchana Ranasinghe
