plot_form_geometry(result, *, boundary=None, tangent_length=4.0, label='FORM', color='C0', ax=None)[source]#

Plot a converged two-dimensional FORM point, radius and tangent.

Parameters:

  • result (FORMResult) – Converged snapshot with two reference coordinates.

  • boundary (ndarray | None) – Ordered boundary points already transformed into the result’s reference coordinates and variable order. No transformation is inferred or run.

  • tangent_length (float) – Half-length of the displayed tangent in reference-space units.

  • label (str) – Legend prefix and color, useful for overlaying transformation orders.

  • color (str) – Legend prefix and color, useful for overlaying transformation orders.

  • ax (Axes | None) – Existing axes. This plot performs no model evaluations.

Returns:

figure, ax – Figure and axes. Nonconverged or higher-dimensional results are rejected; a projection would not preserve the displayed design-point geometry.

Return type:

tuple[Figure, Axes]
