| name | tanabesugano-plot |
| description | Helps agents choose between matplotlib PNG output (cheap, default) and the interactive Prefab LinePlot view when visualizing Tanabe-Sugano diagrams via the TanabeSugano MCP server. Use when the user asks for a plot, graph, or visualization of d-d transitions. |

When to pick which plot tool
| Tool | Pick when |
|---|
ts_plot_png | Default. Static PNG, low token cost, works in every client. Use unless the user explicitly wants interactivity. |
ts_plot_view | The user wants to hover/zoom or compare specific term curves; client is Claude Desktop or another apps/prefab-capable MCP host. Heavy payload — never the default. |
Parameters worth tuning
normalize=True (default) renders the classical Tanabe-Sugano diagram (E/B vs 10Dq/B).normalize=False renders the energy-correlation diagram (cm^-1 axes).steps: 50 is fine for a clean curve; drop to 20 for a sanity-check plot.dq_min/dq_max: bracket the region of interest (e.g., spin-crossover near 2Dq/B~2
for d4-d7) before plotting at the default 0..1500 cm^-1 sweep.
Do not use for
- Polar / Argand / phase plots — not provided.
- 3D rendering — out of scope.
Expected outcome
A single clear plot is returned, and the agent annotates the relevant features in text
rather than uploading multiple variants.
