New "data cursors for matplotlib" package: https://github.com/anntzer/mplcursors
by Antony Lee July 28, 2016

July 28, 2016

Hi all, I have written a new "data cursors for matplotlib" package, inspired from @joferkington's mpldatacursor but rewritten from scratch, with a much simpler API. Please have a look at https://github.com/anntzer/mplcursors . I hope you'll like it. Antony

How's progress with 1.5.2?
by Matthew Brett July 25, 2016

July 25, 2016

Hi, A friend of mine was just asking about 1.5.2 - he needs some fixes that landed after 1.5.1 for his own software package. What's the current ETA? Any tasks we less-experienced matplotlibbers can help with? Cheers, Matthew

TclError with TkAgg + matplotlib 1.5.1 + Anaconda/miniconda on OS X 10.11
by Joseph Long July 21, 2016

July 21, 2016

Hi all, I'm having issues using TkAgg on matplotlib 1.5.1 from the Anaconda distribution that I've been unable to get to the bottom of. When trying to show the plot, I get an exception _tkinter.TclError with the message "invalid command name "PyAggImagePhoto"" and the plot does not display. The full gory details are at the end of this message, but in brief to reproduce (with conda): $ conda create --yes -n testcase-tkinter-2 python=3.5 matplotlib $ source activate testcase-tkinter-2 $ python -c "import matplotlib; matplotlib.use('TkAgg'); from matplotlib import pyplot as plt; plt.plot(1,1); plt.show()" Displaying the plot gets as far as opening a window, but does not show the plot. The exception is "_tkinter.TclError: invalid command name "PyAggImagePhoto"" Based on the warnings emitted (see below), it looks like a library mismatch of some kind between the system Tk and the Anaconda Tk. When I reported the issue to the Anaconda maintainers, I was pointed to this PR: https://github.com/matplotlib/matplotlib/pull/6442 They say that this will fix the issue, but not until 1.5.2 is released. My question, I guess, is: will this fix the issue? And will 1.5.2 be released soon? Many thanks, Joseph Long Space Telescope Science Institute ---- To reproduce the objc warnings on OS X 10.11 with conda: $ conda create --yes -n testcase-tkinter-2 python=3.5 matplotlib $ source activate testcase-tkinter-2 $ python -c "import matplotlib; matplotlib.use('TkAgg'); from matplotlib import pyplot as plt" objc[82465]: Class TKApplication is implemented in both /System/Library/Frameworks/Tk.framework/Versions/8.5/Tk and /Users/jlong/anaconda/envs/testcase-tkinter-2/lib/libtk8.5.dylib.

mpl governance
by Thomas Caswell July 17, 2016

July 17, 2016

Folks, During the sprints at SciPy Mike and I started to adapt the Jupyter governance documents for matplotlib. We are doing this in the open, and a pull request of the changes is at: https://github.com/matplotlib/governance/pull/1 To be clear, this is a work in progress and is not final or in force. We propose the mechanism for ratifying the these documents is to after input from the community to allow the current "matplotlib Executive Committee" to vote. The executive committee is the signers of the FSA with NUMFocus. Tom and Mike

grid line z-order
by Benjamin Root July 16, 2016

July 16, 2016

Hi all.... Looking over the dev docs, I have come to realize that I am not completely sold on the zorder for grid lines. For boxplots, the grid lines fall on top of the boxplots. It seems like this was always the case, though. I would imagine that the gridlines would fall on top of histograms and bar graphs -- which I can convince myself in different situations where the gridlines should fall. Thoughts? Ben Root

v2.0.0b2
by Thomas Caswell July 14, 2016

July 14, 2016

Folks, Last night (and in time for the first day of scipy 2016) we tagged v2.0.0b2. Hopefully this will be the last beta, and we will have an rc soon after scipy. By the end of the day I would like to have a (source) pre release on pypi and available via conda forge. Tom

NBAgg
by mark July 14, 2016

July 14, 2016

hi matplotlibers I am using the NBAgg backend in jupyter notebooks I notice that the option to choose the file format for a saved graphic doesn't appear to be available. This has been discussed: https://github.com/matplotlib/matplotlib/pull/3974#issuecomment-69525569 I have a use case for this, in that my plot is configured by a set of IPywidgets, so the 'figure' isn't in scope for the normal user. How much work would be involved in getting a format picker available as part of the save icon for NBAgg? Is this something I can help with? If so, a pointer or two into relevant places in the code base would be very helpful. much obliged mark

v1.5.2 tag and branch work
by Thomas Caswell July 3, 2016

July 3, 2016

Folks, I have tagged v1.5.2 which is hopefully the end of the 1.5.x series. The v1.5.x and v1.5.1-doc branches have been fully merged up and deleted. I created a v1.5.2-doc branch. Plan to wait to collect all of the wheels before before posting to pypi, updating the website, and making a wider announcement. Given the US holiday, I anticipate this being done July 5 or 6. Big thank you to everyone who helped with this release! Tom
