Post-process an HDF5 file.
==========================

Given an HDF5 file
generated from an :class:`.EvaluationProblem`,
an :class:`.OptimizationProblem`
or a :class:`.Scenario`,
we can visualize the evaluation history using the function :func:`.execute_post`
and a specific visualization tool such as ``"BasicHistory"``:

.. GENERATED FROM PYTHON SOURCE LINES 37-39

.. code-block:: Python

    execute_post("my_results.hdf5", post_name="BasicHistory", variable_names=["y_4"])


.. GENERATED FROM PYTHON SOURCE LINES 40-46

.. note::
   By default, |g| saves the images on the disk.
   Use ``save=False`` to not save figures and ``show=True``
   to display them on the screen.

We can also get the raw data as a :class:`.Database` from this HDF5 file:

.. GENERATED FROM PYTHON SOURCE LINES 46-48

.. code-block:: Python

    database = import_database("my_results.hdf5")


.. GENERATED FROM PYTHON SOURCE LINES 49-51

and convert it into a :class:`.Dataset`` to handle it more easily
(see :ref:`this example <sphx_glr_examples_dataset_creation_plot_dataset.py>`):

.. GENERATED FROM PYTHON SOURCE LINES 51-53

.. code-block:: Python

    dataset = database.to_dataset()


.. GENERATED FROM PYTHON SOURCE LINES 54-59
