Periodic Table

See pymatviz/ptable/ptable_plotly.py. The module supports heatmaps, heatmap splits (multiple values per element), histograms, scatter plots and line plots. All visualizations are interactive through Plotly and support displaying additional data on hover.

Warning

Version 0.16.0 of pymatviz dropped the matplotlib-based functions in ptable_matplotlib.py in #270. Please use the plotly-based functions shown below instead which have feature parity, interactivity and better test coverage.

ptable_heatmap_plotly(atomic_masses)	ptable_heatmap_plotly(compositions, log=True)
ptable_hists_plotly(data)	ptable_scatter_plotly(data, mode="markers")
ptable_heatmap_splits_plotly(2_vals_per_elem)	ptable_heatmap_splits_plotly(3_vals_per_elem)

Dash app using ptable_heatmap_plotly()

See examples/mprester_ptable.ipynb.
