Save matplotlib figures with embedded metadata for reproducibility and profit

Project Description

Remember that time where you tried to remake a figure for your paper and couldn’t seem to get the same results? We’ve all been there. Well not anymore!

This module monkey patches the savefig command from matplotlib and inserts your current git commit hash into the metadata of the saved file. Currently it supports PNG and PDF figures.

Usage

First, install the module from PyPI:

pip install savefig

or from source:

git clone https://github.com/dfm/savefig.git
cd savefig
python setup.py install

Then in all your code just add the following lines before importing matplotlib:

from savefig import monkey_patch
monkey_patch()

To read the metadata from an existing image file, run:

python -m savefig /path/to/figure.png

which will give you something like:

git-hash: 192a639c4a9eb7523e9becd23f359fd7d96e833f
git-date: 2014-03-29 21:30:27 -0400
git-author: Dan F-M

You can also get the diff between the saved commit hash and the version used to make the figure by running:

python -m savefig /path/to/figure.png --diff
