Hi,

I am on MacOS and using the MacOSX backend. When a plot is displayed and I want to save it, I cannot change the name or go right/left in the text entry, the keyboard is not working. It was working properly before with matplotlib 1.5.1, now I upgraded to 2.0.2 (with anaconda). For now I am using the PyQt5 backend, which is OK, but if I move my plot to my second monitor (higher resolution), the window size stays the same but not the plots which is over-zoomed :-/ Any ideas to make the MacOSX backend works or solved the "dpi" issue for PyQt5?

  • Operating System: Mac OSX 10.12.6
  • Matplotlib Version: 2.0.2
  • Python Version: 2.7.13
  • Jupyter Version (if applicable):
  • Other Libraries:

    Keyboard bindings are not working either. Other things like zooming seem to work correctly.

    #8931 fixed the mixed resolution issue on Qt5. I'm not seeing the same issues as you on the OSX backend, so maybe it's a python 2 only issue.

    Ok thank you very much. Do I have to make the changes from #8931 in the .py files myself or I can download them somewhere?

    Well, if I copy and past the corresponding corrected file (backend_qt5.py), I have the following error when starting ipython: "ImportError: cannot import name _Backend".
    Am I doing something wrong!

    That file also depends on other files that have changed since 2.0.2 has been released, so just copying that file will not work. I'll let the OSX devs comment on the best way to install off master.

    How exactly

    The problem with mac may be related related to IPython's switch from readline -> prompt toolkit (but if zoom is working, that may not be the issue).

    Have you tried doing %matplotlib to make sure the event loop integration is set up correctly?

    There are also issue with osx + 'framework' builds see http://matplotlib.org/faq/osx_framework.html#osxframework-faq

    Zoom is indeed working for the macosx backend (note that I used a terminal to run python with: ipython --pylab). It worked before with previous version of matplotlib and ipython. What about PyQt5 and the changes from #8931, how can I make them work on my computer?

    I did it yesterday and it did not change anything unfortunately.

    Ok, so I removed all matplotlib versions I had in my .../site-packages/ directory, and installed the fresh one. The PyQt5 mixed resolution display (#8931) issue is fixed for me now. Thanks.

    @mdehoon Any guidance on what is wrong with the native backend?

    I can't get IPython to run with the osx backend.

    If I run a plot from the command line using pythonw, I can't reproduce any problems with the keyboard. The default keybindings work and saving a figure is fine.

    The issue in IPython is likely missing integration with prompt toolkit (attn @Carreau )

    @dopplershift I can't get ipython to rin the macos backend either. It gives me the "Framework required" error...

    I observed this issue on a number of systems today, but did not get details of IPython / OSX versions, but mostly with mpl 2.1 (I think?).

    @jklymak, in a conda environment, this works for me with matplotlib 2.1.0.post222+gad730d131 (which is just what I happen to have in that environment at the moment):

    Oh, and the which python trick. OK that works. But...

    ...but the buttons don't work quite right. Very strange. Zoom and pan seem to work, but home, backwards, and forwards are erratic.

    Both the forward/back/home buttons and the keyboard events are working fine for me with the current v2.1.x branch in IPython (using %matplotlib osx). I'm going to close this out, but feel free to re-open if you find this is a problem with 2.1.1 when that is released.
