A toolkit for visualizations in materials informatics

Project description

pymatviz

A toolkit for visualizations in materials informatics.

Tests pre-commit.ci status This project supports Python 3.8+ PyPI PyPI Downloads

Note: This project is not associated with or endorsed by pymatgen, but aims to complement it by adding additional plotting functionality.

Installation

pip install pymatviz

Usage

Check out the Jupyter notebooks under examples/ to learn how to use pymatviz.

matbench_dielectric_eda.ipynb Binder View on GitHub Open in Google Colab
mp_bimodal_e_form.ipynb Binder View on GitHub Open in Google Colab
matbench_perovskites_eda.ipynb Binder View on GitHub Open in Google Colab
mprester_ptable.ipynb Binder View on GitHub Open in Google Colab

When trying to open notebooks in Google Colab, you might encounter errors. Colab currently only supports Python 3.7. pymatviz uses Python 3.8 features like self-documenting f-strings. You may still be able to use pymatviz on Colab by cloning the repo and patching the source code in-place as shown here.

Periodic Table

See pymatviz/ptable.py. Heat maps of the periodic table can be plotted both with matplotlib and plotly. plotly supports displaying additional data on hover or full interactivity through Dash.

ptable_heatmap(compositions, log=True) ptable_heatmap_ratio(comps_a, comps_b)
ptable-heatmap ptable-heatmap-ratio
ptable_heatmap_plotly(atomic_masses) ptable_heatmap_plotly(compositions)
ptable-heatmap-plotly-more-hover-data ptable-heatmap-plotly-log

Dash app using ptable_heatmap_plotly()

See examples/mprester_ptable.ipynb.

Sunburst

Structure

See pymatviz/structure_viz.py. Currently structure plotting is only supported with matplotlib in 2d. 3d interactive plots (probably with plotly) are on the road map.

Glossary

  1. Residual y_res = y_true - y_pred: The difference between ground truth target and model prediction.
  2. Error y_err = abs(y_true - y_pred): Absolute error between target and model prediction.
  3. Uncertainty y_std: The model's estimate for its error, i.e. how much the model thinks its prediction can be trusted. (std for standard deviation.)
