quartic2d.Interaction.plot_convergence

Interaction.plot_convergence(title='Interaction convergence')

Plot the attached interaction-level convergence record.

Parameters:

title (str, default="Interaction convergence") – Figure title. Pass an empty string to suppress it.

Returns:

• fig (matplotlib.figure.Figure) – Created figure.

• axes (ndarray of matplotlib.axes.Axes) – Method-specific convergence-diagnostic axes.

Raises:

RuntimeError – If the interaction was not constructed from Interaction.converge_parameters(...).

Notes

This method delegates to InteractionConvergenceResult.plot_convergence(). The plot shows internal self-convergence and robustness diagnostics, not an independent reference error.
