The widget backend doesn't seem to work for me. Even very simple plots don't show up. This issue looks like #171, but for me even simple matplotlib plots don't show up.

Behaviour with inline backend

%matplotlib inline
import matplotlib.pyplot as plt

plt.plot([[1, 2], [0, 0]])

%matplotlib widget

There isn't a new window with the plot either.

Are you using Jupyter Notebook or JupyterLab?

For some reason your jupyter-matplotlib extension is not installed.

Can you try running the following and restart Jupyter Notebook:

jupyter nbextension install --py --sys-prefix --overwrite ipympl
jupyter nbextension enable --py --sys-prefix ipympl

Thanks for the pointer, that works. Although I prefer to install packages with my own package manager. If you want, you can take a look below and try to see what's wrong with the package, but otherwise, thanks for helping!

I did install it using the AUR (Arch User Repostory). It might be that that build scripts doesn't work correctly. I'm not too familiar with jupyter extensions, but there is a (symlinked) directory jupyter-matplotlib in /usr/share/jupyter/nbextensions, next to jupyter-js-widgets (which does get recognized).

Unfortunately it seems the python-ipympl package does not work in the AUR.

but there is a (symlinked) directory

Where does it link to?

I can only suggest using the conda-forge package, or the pip package, that we maintain.

Allright, thank you. I'll contact the maintainers of the AUR package and use the jupyter one for now :)

Sorry to ask where should I running the above commands? Should i try it in my conda envirment? I get this results and there is still no plots shown in my jupyter notebook cell:

If you're using anaconda, you should probably use the conda package manager: https://anaconda.org/conda-forge/ipympl
