pyscat.plot

Plotting functions for PyScat.

Functions

plot_ess_history(history)

Plot the history of the eSS optimization.

plot_sacess_history(histories[, ax])

Plot SacessOptimizer history.
pyscat.plot.merge_monotonic_histories(histories, strict=True)[source]

Get the overall monotonically decreasing history from multiple histories.

Parameters:

  • histories (list[HistoryBase]) – List of histories to merge. The histories are expected to have time and function value traces, and that the function values are monotonically decreasing within each history.

  • strict (bool)

Return type:

tuple[ndarray, ndarray]

Returns:

t:

Time points of overall history.

fx:

Objective values of overall history.

pyscat.plot.plot_ess_history(history)[source]

Plot the history of the eSS optimization.

Parameters:

history (HistoryBase)

pyscat.plot.plot_sacess_history(histories, ax=None)[source]

Plot SacessOptimizer history.

Plot the history of the best objective values for each SacessOptimizer worker over computation time as step splot.

Parameters:

  • histories (list[HistoryBase]) – List of histories from different workers as obtained from SacessOptimizer.histories.

  • ax (Axes | None) – Axes object to use.

Return type:

Axes

Returns:

The plot axes. ax or a new axes if ax was None.
