ipympl

TravisCI build status Latest PyPI version Latest conda-forge version Latest npm version Binder Gitter

Leveraging the Jupyter interactive widgets framework, ipympl enables the interactive features of matplotlib in the Jupyter notebook and in JupyterLab.

Besides, the figure canvas element is a proper Jupyter interactive widget which can be positioned in interactive widget layouts.

Usage

To enable the ipympl backend, simply use the matplotlib Jupyter magic:

%matplotlib widget

Example

See the example notebook for more!

Installation

With conda:

conda install -c conda-forge ipympl

With pip:

pip install ipympl

Use in JupyterLab

If you want to use ipympl in JupyterLab, we recommend using JupyterLab >= 3.

If you use JupyterLab 2, you still need to install the labextension manually:

conda install -c conda-forge nodejs
jupyter labextension install @jupyter-widgets/jupyterlab-manager jupyter-matplotlib

Install an old JupyterLab extension

If you are using JupyterLab 1 or 2, you will need to install the right jupyter-matplotlib version, according to the ipympl and jupyterlab versions you installed. For example, if you installed ipympl 0.5.1, you need to install jupyter-matplotlib 0.7.0, and this version is only compatible with JupyterLab 1.

conda install -c conda-forge ipympl==0.5.1
jupyter labextension install @jupyter-widgets/jupyterlab-manager jupyter-matplotlib@0.7.0

Versions lookup table:

ipympl jupyter-matplotlib JupyterLab Matplotlib
0.5.8 0.7.4 1 or 2 3.3.1
0.5.7 0.7.3 1 or 2 3.2.*
... ... ...
0.5.3 0.7.2 1 or 2
0.5.2 0.7.1 1
0.5.1 0.7.0 1
0.5.0 0.6.0 1
0.4.0 0.5.0 1
0.3.3 0.4.2 1
0.3.2 0.4.1 1
0.3.1 0.4.0 0 or 1

For a development installation (requires nodejs):

Create a dev environment that has nodejs installed. The instructions here use mamba but you can also use conda.

mamba env create --file dev-environment.yml
conda activate ipympl-dev

Install the Python Packge

pip install -e .

When developing your extensions, you need to manually enable your extensions with the notebook / lab frontend. For lab, this is done by the command:

jupyter labextension develop --overwrite .
npm run build

For classic notebook, you need to run:

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

How to see your changes

Javascript:

You need to rebuild the JS when you make a code change:

cd js
yarn run watch

After a change wait for the build to finish and then refresh your browser and the changes should take effect.

Python:

If you make a change to the python code then you will need to restart the notebook kernel to have it take effect.
