Plot a `~gwpy.segments.SegmentListDict` onto
        these axes

        Parameters
        ----------
        segmentlistdict : `~gwpy.segments.SegmentListDict`
            (name, `~gwpy.segments.SegmentList`) dict

        y : `float`, optional
            starting y-axis value for new segmentlists

        **kwargs
            any other keyword arguments acceptable for
            `~matplotlib.patches.Rectangle`

        Returns
        -------
        collections : `list`
            list of `~matplotlib.patches.PatchCollection` sets for
            each segmentlist
