ProPlot is published on PyPi and conda-forge. It can be installed with pip or conda as follows:

pip install proplot
conda install -c conda-forge proplot

Likewise, an existing installation of ProPlot can be upgraded to the latest version with:

pip install --upgrade proplot
conda upgrade proplot

If you used pip install git+ to install ProPlot before it was released on PyPi, you may need to run pip uninstall proplot before upgrading. To install a development version of ProPlot, you can use this same method, or clone the repository and run pip install --upgrade . inside the proplot folder.

ProPlot’s only hard dependency is matplotlib. The soft dependencies are cartopy, basemap, xarray, and pandas. See the documentation for details.
