constraints_history module¶
A constraints plot.
- 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 (gemseo.algos.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
- check_options(**options)¶
Check the options of the post-processor.
- 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 (str | Path | None) –
The path of the file to save the figures. If the extension is missing, use
file_extension
. If None, create a file path fromdirectory_path
,file_name
andfile_extension
.By default it is set to None.
directory_path (str | Path | None) –
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 (str | None) –
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 (str | None) –
A file extension, e.g. ‘png’, ‘pdf’, ‘svg’, … If None, use a default file extension.
By default it is set to None.
fig_size (tuple[float, float] | None) –
The width and height of the figure in inches, e.g. (w, h). If None, use the
OptPostProcessor.DEFAULT_FIG_SIZE
of the post-processor.By default it is set to None.
**options (OptPostProcessorOptionType) – The options of the post-processor.
- Returns
The figures, to be customized if not closed.
- Raises
ValueError – If the opt_problem.database is empty.
- DEFAULT_FIG_SIZE = (11.0, 11.0)¶
The default width and height of the figure, in inches.
- property figures: dict[str, matplotlib.figure.Figure]¶
The Matplotlib figures indexed by a name, or the nameless figure counter.
- materials_for_plotting: dict[Any, Any]¶
The materials to eventually rebuild the plot in another framework.
- opt_problem: OptimizationProblem¶
The optimization problem.
