        Check box returned type is correct

        Parameters
        ----------
        returned : object to be tested, returned from boxplot
        return_type : str
            return_type passed to boxplot
        expected_keys : list-like, optional
            group labels in subplot case. If not passed,
            the function checks assuming boxplot uses single ax
        check_ax_title : bool
            Whether to check the ax.title is the same as expected_key
            Intended to be checked by calling from ``boxplot``.
            Normal ``plot`` doesn't attach ``ax.title``, it must be disabled.

    Create plot and ensure that plot return object is valid.

    Parameters
    ----------
    f : func
        Plotting function.
    filterwarnings : str
        Warnings filter.
        See https://docs.python.org/3/library/warnings.html#warning-filter
    default_axes : bool, optional
        If False (default):
            - If `ax` not in `kwargs`, then create subplot(211) and plot there
            - Create new subplot(212) and plot there as well
            - Mind special corner case for bootstrap_plot (see `_gen_two_subplots`)
        If True:
            - Simply run plotting function with kwargs provided
            - All required axes instances will be created automatically
            - It is recommended to use it when the plotting function
            creates multiple axes itself. It helps avoid warnings like
            'UserWarning: To output multiple subplots,
            the figure containing the passed axes is being cleared'
    **kwargs
        Keyword arguments passed to the plotting function.

    Returns
    -------
    Plot object returned by the last plotting.
