Parallel coordinates
====================

In this example, we illustrate the use of the
:class:`~gemseo.post.para_coord.ParallelCoordinates` plot on the Sobieski's SSBJ
problem.

Import
------
The first step is to import some functions from the API
and a method to get the design space.

.. GENERATED FROM PYTHON SOURCE LINES 40-47

.. code-block:: default

    from gemseo.api import configure_logger, create_discipline, create_scenario
    from gemseo.problems.sobieski.core import SobieskiProblem

    configure_logger()

    standard_library.install_aliases()








.. GENERATED FROM PYTHON SOURCE LINES 48-52

Create disciplines
------------------
Then, we instantiate the disciplines of the Sobieski's SSBJ problem:
Propulsion, Aerodynamics, Structure and Mission

.. GENERATED FROM PYTHON SOURCE LINES 52-61

.. code-block:: default

    disciplines = create_discipline(
        [
            "SobieskiPropulsion",
            "SobieskiAerodynamics",
            "SobieskiStructure",
            "SobieskiMission",
        ]
    )








.. GENERATED FROM PYTHON SOURCE LINES 62-65

Create design space
-------------------
We also read the design space from the :class:`.SobieskiProblem`.

.. GENERATED FROM PYTHON SOURCE LINES 65-67

.. code-block:: default

    design_space = SobieskiProblem().read_design_space()








.. GENERATED FROM PYTHON SOURCE LINES 68-75

Create and execute scenario
---------------------------
The next step is to build a MDO scenario in order to maximize the range,
encoded 'y_4', with respect to the design parameters, while satisfying the
inequality constraints 'g_1', 'g_2' and 'g_3'. We can use the MDF formulation,
the SLSQP optimization algorithm
and a maximum number of iterations equal to 100.

.. GENERATED FROM PYTHON SOURCE LINES 75-87

.. code-block:: default

    scenario = create_scenario(
        disciplines,
        formulation="MDF",
        objective_name="y_4",
        maximize_objective=True,
        design_space=design_space,
    )
    scenario.set_differentiation_method("user")
    for constraint in ["g_1", "g_2", "g_3"]:
        scenario.add_constraint(constraint, "ineq")
    scenario.execute({"algo": "SLSQP", "max_iter": 10})

 Out:

 .. code-block:: none


    {'algo': 'SLSQP', 'max_iter': 10}



.. GENERATED FROM PYTHON SOURCE LINES 88-93

Post-process scenario
---------------------
Lastly, we post-process the scenario by means of the
:class:`~gemseo.post.para_coord.ParallelCoordinates` plot which parallel
coordinates plots among design variables, objective function and constraints.

.. GENERATED FROM PYTHON SOURCE LINES 93-94

.. code-block:: default

    scenario.post_process("ParallelCoordinates", save=False, show=True)
