Installation

pip install pymatviz

API Docs

See the /api page.

Usage

See the Jupyter notebooks under examples/ for how to use pymatviz. PRs with additional examples are welcome! 🙏

Periodic Table

See pymatviz/ptable/ptable_matplotlib.py and pymatviz/ptable/ptable_plotly.py. matplotlib supports heatmaps, heatmap ratios, heatmap splits (multiple values per element), histograms, scatter plots and line plots. plotly currently only supports heatmaps (PRs to port over other matplotlib ptable variants to plotly are very welcome!). The plotly heatmap 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_plotly(atomic_masses)	ptable_heatmap_plotly(compositions, log=True)
ptable_hists(data, colormap="coolwarm")	ptable_lines(data)
ptable_scatters(data, colormap="coolwarm")	ptable_scatters(data, colormap="coolwarm")
ptable_heatmap_splits(2_vals_per_elem, colormap="coolwarm", start_angle=135)	ptable_heatmap_splits(3_vals_per_elem, colormap="coolwarm", start_angle=90)

Phonons

See examples/mlff_phonons.ipynb for usage example.

plot_phonon_bands(bands_dict)	plot_phonon_dos(doses_dict)
plot_phonon_bands_and_dos(bands_dict, doses_dict)	plot_phonon_bands_and_dos(single_bands, single_dos)

Dash app using ptable_heatmap_plotly()

See examples/mprester_ptable.ipynb.

Sunburst

See pymatviz/sunburst.py.

spacegroup_sunburst([65, 134, 225, ...])	spacegroup_sunburst(["C2/m", "P-43m", "Fm-3m", ...])

Sankey

See pymatviz/sankey.py.

sankey_from_2_df_cols(df_perovskites)	sankey_from_2_df_cols(df_rand_ints)

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.

plot_structure_2d(mp_19017)	plot_structure_2d(mp_12712)

Histograms

See pymatviz/histograms.py.

spacegroup_hist([65, 134, 225, ...], backend="matplotlib")	spacegroup_hist(["C2/m", "P-43m", "Fm-3m", ...], backend="matplotlib")
spacegroup_hist([65, 134, 225, ...], backend="plotly")	spacegroup_hist(["C2/m", "P-43m", "Fm-3m", ...], backend="plotly")
elements_hist(compositions, log=True, bar_values='count')	plot_histogram({'key1': values1, 'key2': values2})

Scatter Plots

See pymatviz/scatter.py.

density_scatter_plotly(df, x=x_col, y=y_col, ...)	density_scatter_plotly(df, x=x_col, y=y_col, ...)
density_scatter(xs, ys, ...)	density_scatter_with_hist(xs, ys, ...)
density_hexbin(xs, ys, ...)	density_hexbin_with_hist(xs, ys, ...)

X-Ray Diffraction

See pymatviz/xrd.py.

plot_xrd_pattern(pattern)	plot_xrd_pattern({key1: patt1, key2: patt2})

Uncertainty

See pymatviz/uncertainty.py.

qq_gaussian(y_true, y_pred, y_std)	qq_gaussian(y_true, y_pred, y_std: dict)
error_decay_with_uncert(y_true, y_pred, y_std)	error_decay_with_uncert(y_true, y_pred, y_std: dict)

Cumulative Metrics

See pymatviz/cumulative.py.

cumulative_error(preds, targets)	cumulative_residual(preds, targets)

Classification

See pymatviz/relevance.py.

roc_curve(targets, proba_pos)	precision_recall_curve(targets, proba_pos)

Correlation

See pymatviz/correlation.py.

marchenko_pastur(corr_mat, gamma=ncols/nrows)	marchenko_pastur(corr_mat_significant_eval, gamma=ncols/nrows)
