para_coord module¶
A parallel coordinates plot of functions and x.
Classes:
|
Parallel coordinates among design variables, outputs functions and constraints. |
- class gemseo.post.para_coord.ParallelCoordinates(opt_problem)[source]¶
Bases:
gemseo.post.opt_post_processor.OptPostProcessor
Parallel coordinates among design variables, outputs functions and constraints.
x- and y- figure sizes can be changed in option.
- Attributes
opt_problem (OptimizationProblem) – The optimization problem.
database (Database) – The database generated by the optimization problem.
out_data_dict (Dict[Any,Any]) – The data dict to eventually rebuild the plot in another framework.
- 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
Methods:
check_options
(**options)Check the options of the post-processor.
execute
([save, show, file_path, …])Post-process the optimization problem.
parallel_coordinates
(y_data, x_names, …)Plot the parallel coordinates.
Attributes:
The Matplotlib figures indexed by a name, or the nameless figure counter.
The paths to the output files.
- check_options(**options)¶
Check the options of the post-processor.
- Parameters
**options – The options of the post-processor.
options (Union[int, float, str, bool, Sequence[str]]) –
- 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, **options)¶
Post-process the optimization problem.
- Parameters
save (bool) – If True, save the figure.
show (bool) – If True, display the figure.
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 fromdirectory_path
,file_name
andfile_extension
.directory_path (Optional[Union[str, pathlib.Path]]) – The path of the directory to save the figures. If None, use the current working directory.
file_name (Optional[str]) – The name of the file to save the figures. If None, use a default one generated by the post-processing.
file_extension (Optional[str]) – A file extension, e.g. ‘png’, ‘pdf’, ‘svg’, … If None, use a default file extension.
**options – The options of the post-processor.
options (Union[int, float, str, bool, Sequence[str]]) –
- Returns
The figure, 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.
- static parallel_coordinates(y_data, x_names, color_criteria, figsize_x, figsize_y)[source]¶
Plot the parallel coordinates.
- Parameters
y_data (numpy.ndarray) – The lines data to plot.
x_names (Sequence[str]) – The names of the abscissa.
color_criteria (Sequence[float]) – The values of same length as y_data to colorize the lines.
figsize_x (int) – The size of the figure in horizontal direction (inches).
figsize_y (int) – The size of the figure in vertical direction (inches).
- Return type
matplotlib.figure.Figure
