        Conduct the formerly registered updates

        This method conducts the updates that have been registered via the
        :meth:`update` method. You can call this method if the
        :attr:`no_auto_update` attribute of this instance and the `auto_update`
        parameter in the :meth:`update` method has been set to False

        Parameters
        ----------
        draw: bool or None
            Boolean to control whether the figure of this array shall be drawn
            at the end. If None, it defaults to the `'auto_draw'`` parameter
            in the :attr:`psyplot.rcParams` dictionary
        queues: list of :class:`Queue.Queue` instances
            The queues that are passed to the
            :meth:`psyplot.plotter.Plotter.start_update` method to ensure a
            thread-safe update. It can be None if only one single plotter is
            updated at the same time. The number of jobs that are taken from
            the queue is determined by the :meth:`_njobs` attribute. Note that
            there this parameter is automatically configured when updating
            from a :class:`~psyplot.project.Project`.

        Returns
        -------
        bool
            A boolean indicating whether a redrawing is necessary or not
