constraints_history module

A constraints plot.

Classes:

ConstraintsHistory(opt_problem)

Plot of the constraint function history with line charts.

class gemseo.post.constraints_history.ConstraintsHistory(opt_problem)[source]

Bases: gemseo.post.opt_post_processor.OptPostProcessor

Plot of the constraint function history with line charts.

Indicate the violation with color on the background.

The plot method requires the constraint names to plot. It is possible either to save the plot, to show the plot or both.

Parameters

opt_problem (OptimizationProblem) – The optimization problem to be post-processed.

Raises

ValueError – If the JSON grammar file for the options of the post-processor does not exist.

Return type

None

Attributes:

DEFAULT_FIG_SIZE

The default width and height of the figure, in inches.

figures

The Matplotlib figures indexed by a name, or the nameless figure counter.

output_files

The paths to the output files.

Methods:

check_options(**options)

Check the options of the post-processor.

execute([save, show, file_path, ...])

Post-process the optimization problem.

DEFAULT_FIG_SIZE = (11.0, 11.0)

The default width and height of the figure, in inches.

Type

tuple(float, float)

check_options(**options)

Check the options of the post-processor.

Parameters

**options (Union[int, float, str, bool, Sequence[str]]) – The options of the post-processor.

Raises

InvalidDataException – If an option is invalid according to the grammar.

Return type

None

execute(save=True, show=False, file_path=None, directory_path=None, file_name=None, file_extension=None, fig_size=None, **options)

Post-process the optimization problem.

Parameters
  • save (bool) –

    If True, save the figure.

    By default it is set to True.

  • show (bool) –

    If True, display the figure.

    By default it is set to False.

  • file_path (Optional[Union[str, pathlib.Path]]) –

    The path of the file to save the figures. If the extension is missing, use file_extension. If None, create a file path from directory_path, file_name and file_extension.

    By default it is set to None.

  • directory_path (Optional[Union[str, pathlib.Path]]) –

    The path of the directory to save the figures. If None, use the current working directory.

    By default it is set to None.

  • file_name (Optional[str]) –

    The name of the file to save the figures. If None, use a default one generated by the post-processing.

    By default it is set to None.

  • file_extension (Optional[str]) –

    A file extension, e.g. ‘png’, ‘pdf’, ‘svg’, … If None, use a default file extension.

    By default it is set to None.

  • fig_size (Optional[Tuple[float, float]]) –

    The width and height of the figure in inches, e.g. (w, h). If None, use the DEFAULT_FIG_SIZE of the post-processor.

    By default it is set to None.

  • **options (Union[int, float, str, bool, Sequence[str]]) – The options of the post-processor.

Returns

The figures, to be customized if not closed.

Raises

ValueError – If the opt_problem.database is empty.

Return type

Dict[str, matplotlib.figure.Figure]

property figures

The Matplotlib figures indexed by a name, or the nameless figure counter.

property output_files

The paths to the output files.
