Matplotlib plots not showing up in Mac OSX?

Question

I am running Mac OSX 10.5.8. I installed matplotlib using macports. I get some examples from the matplotlib gallery like this one, without modification:

Answer 1

Mac comes with its own python (read from here, which is not the best), I would suggest just a clean install of some Python 3.7 or so along with Anaconda and then introduce them as interpreters to PyCharm. anything will work fine and you wont need to add ad-hoc solutions like "backend: MacOSX" or so.

Answer 2

After the plot simply add -

plt.show()

The reason this works is to do with interactive vs non-interactive mode. If the backend is opened in non-interactive mode, plt.show() is required at the end of the code chunk. You can check the status by calling plt.isinteractive() and toggle the status using plt.ion() and plt.ioff()

Answer 3

I wanna share this workable solution for me,

import matplotlib
import platform
if platform.system() == 'Darwin':
    matplotlib.use('MacOSX')

Answer 4

This is what worked for me:

brew install pkg-config
brew link pkg-config
brew install pygtk
brew install freetype
brew install libpng

sudo ln -s /usr/local/Cellar/freetype/*/lib/pkgconfig/freetype2.pc /usr/local/lib/pkgconfig/freetype2.pc

git clone git@github.com:matplotlib/matplotlib.git
cd matplotlib
python setup.py build
python setup.py install

Answer 5

I had the same problem, even I could see how a new application window was created and immediately disappeared.

Simple solution - just check if you have

plt.show()

after the plot

Answer 6

just to add a note,

The matplotlibrc file was not present on my system and I had to to download a copy from the matplotlib website. Future users may have to do the same.
