    .. seealso::
        Please refer to :func:`optuna.visualization.plot_param_importances` for an example.

    Args:
        study:
            An optimized study.
        evaluator:
            An importance evaluator object that specifies which algorithm to base the importance
            assessment on.
            Defaults to
            :class:`~optuna.importance.FanovaImportanceEvaluator`.
        params:
            A list of names of parameters to assess.
            If :obj:`None`, all parameters that are present in all of the completed trials are
            assessed.
        target:
            A function to specify the value to display. If it is :obj:`None` and ``study`` is being
            used for single-objective optimization, the objective values are plotted.
            For multi-objective optimization, all objectives will be plotted if ``target``
            is :obj:`None`.

            .. note::
                This argument can be used to specify which objective to plot if ``study`` is being
                used for multi-objective optimization. For example, to get only the hyperparameter
                importance of the first objective, use ``target=lambda t: t.values[0]`` for the
                target parameter.
        target_name:
            Target's name to display on the axis label. Names set via
            :meth:`~optuna.study.Study.set_metric_names` will be used if ``target`` is :obj:`None`,
            overriding this argument.

    Returns:
        A :class:`matplotlib.axes.Axes` object.
