`` attribute of the `.AnnotationBbox`).
            If *frameon* is set to False, this patch is made invisible.

        annotation_clip: bool or None, default: None
            Whether to clip (i.e. not draw) the annotation when the annotation
            point *xy* is outside the axes area.

            - If *True*, the annotation will be clipped when *xy* is outside
              the axes.
            - If *False*, the annotation will always be drawn.
            - If *None*, the annotation will be clipped when *xy* is outside
              the axes and *xycoords* is 'data'.

        pad : float, default: 0.4
            Padding around the offsetbox.

        box_alignment : (float, float)
            A tuple of two floats for a vertical and horizontal alignment of
            the offset box w.r.t. the *boxcoords*.
            The lower-left corner is (0, 0) and upper-right corner is (1, 1).

        bboxprops : dict, optional
            A dictionary of properties to set for the annotation bounding box,
            for example *boxstyle* and *alpha*.  See `.FancyBboxPatch` for
            details.

        arrowprops: dict, optional
            Arrow properties, see `.Annotation` for description.

        fontsize: float or str, optional
            Translated to points and passed as *mutation_scale* into
            `.FancyBboxPatch` to scale attributes of the box style (e.g. pad
            or rounding_size).  The name is chosen in analogy to `.Text` where
            *fontsize* defines the mutation scale as well.  If not given,
            :rc:`legend.fontsize` is used.  See `.Text.set_fontsize` for valid
            values.

        **kwargs
            Other `AnnotationBbox` properties.  See `.AnnotationBbox.set` for
            a list.
