Stemgraphic requires docopt, matplotlib and pandas. Optionally, having Scipy installed will give you secondary plots and Dask (see requirements.txt for all needed to run all the functional tests) will allow for out of core, big data visualization.
Installation is simple:
pip3 install -U stemgraphic
or from this cloned repository, in the package root:
python3 setup.py install
For operations with dask, performance has been increased by 25% in this latest release, by doing a compute once of min, max and count all at once. Count replaces len(x).
Added the companion PDF as it will be presented at PyData Carolinas 2016.
