ArviZ-plots provides ready to use and composable plots for Bayesian Workflow.

arviz-plots

ArviZ (pronounced "AR-vees") is a Python package for exploratory analysis of Bayesian models. It includes functions for posterior analysis, data storage, model checking, comparison and diagnostics.

arviz-plots is the subpackage in charge of the visualizations.

ArviZ in other languages

ArviZ also has a Julia wrapper available ArviZ.jl.

Documentation

The ArviZ documentation can be found in the official docs. Here are some quick links for common scenarios:

• First time Bayesian modelers and ArviZ users: EABM book
• First time ArviZ users, already familiar with Bayesian modeling: overview notebook or example gallery
• ArviZ 0.x user: migration guide
• ArviZ-verse documentation:
  • arviz-base
  • arviz-stats
  • arviz-plots (this package)

Installation

Stable

ArviZ is available for installation from PyPI. The latest stable version can be installed using pip:

pip install "arviz-plots[backend]"

Note that arviz-plots is a minimal package, which only depends on xarray, numpy, arviz-base and arviz-stats. None of the possible backends: matplotlib, bokeh or plotly are installed by default.

Consequently, it is not recommended to install arviz-plots but instead to choose which backend to use. For example arviz-plots[matplotlib] or arviz-plots[matplotlib, plotly], multiple comma separated values are valid too.

Development

The latest development version can be installed from the main branch using pip:

pip install git+git://github.com/arviz-devs/arviz-plots.git

Another option is to clone the repository and install using git and setuptools:

git clone https://github.com/arviz-devs/arviz-plots.git
cd arviz-plots
python setup.py install
