Convex Hulls

Ternary Chemical Systems

Quaternary Chemical Systems

• Drag & drop: load your own JSON data onto the quaternary diagrams

Binary Chemical Systems

Statistics Panel

Use bind:this to access the renderer, then derive renderer?.get_model() for an external statistics panel. The model contains all phases; the built-in info pane follows the plot’s visibility threshold.

• Shared model: get_model() exposes the current numerical hull for ConvexHullStats model={model}; display thresholds and categories do not change the model
• Headless computation: compute_hull_model(entries) builds the same model without mounting a diagram
• Row highlighting: click a table row to highlight it (highlighted_entry_id + on_entry_click)
• Clickable IDs: entry_href callback turns the ID column into links
• Poly column: shows polymorph count per reduced formula
• Polymorphs filter: dropdown to isolate entries sharing a composition
• Subsystem coverage: grid of binary element pairs with entry counts
• CSV/JSON export: download table data

Side-by-Side Layout

• layout="side-by-side": stats and table visible simultaneously, no toggle needed

Highlighted Entries

• API: highlighted_entries + highlight_style (pulse/glow effect, color, size multiplier) on 2D, 3D and 4D

Magnetic States & Custom Categories

• Shape-coded orderings: entries with magnetic_ordering render as △ FM, ◆ FiM, ■ AFM, ● NM (built-in default entry_category)
• Filter toggles: show/hide magnetic subsets via the controls pane (bindable hidden_categories)
• Generic API: pass a custom EntryCategoryConfig to shape-code any classification (right plot: crystallinity; works equally for metal/semiconductor/insulator, defect types, ...)
• Manual override: a per-entry marker field always takes precedence over category shapes

Synthetic orderings are assigned by entry-ID hash. Missing pure-element references are added with E_form = 0 eV/atom.

Temperature-Dependent Free Energies

• Temperature slider: appears when entries include temperatures + free_energies arrays
• Synthetic G(T) data: every composition has an ordered and a high-entropy polymorph, so hull membership shifts with temperature

Gas Atmosphere Control

• Chemical potential: gas-forming elements (O, N, H, C, F) use μ(T, P) = μ°(T) + k_BT·ln(P/P₀) / n_atoms (per-atom convention, P in bar, P₀ = 1 bar)
• Multi-gas support: O₂, N₂, H₂, CO, CO₂, H₂O, F₂

Standalone Stats for Quinary Systems

• Standalone stats: use ConvexHullStats without rendering a hull
• High-dimensional support: computed via process_hull_for_stats() for systems with 5+ elements
