        Set the angles at which to place the theta grids (these
        gridlines are equal along the theta dimension).  *angles* is in
        degrees.

        *labels*, if not None, is a ``len(angles)`` list of strings of
        the labels to use at each angle.

        If *labels* is None, the labels will be ``fmt %% angle``

        *frac* is the fraction of the polar axes radius at which to
        place the label (1 is the edge). Eg. 1.05 is outside the axes
        and 0.95 is inside the axes.

        Return value is a list of tuples (*line*, *label*), where
        *line* is :class:`~matplotlib.lines.Line2D` instances and the
        *label* is :class:`~matplotlib.text.Text` instances.

        kwargs are optional text properties for the labels:

        Set the radial locations and labels of the *r* grids.

        The labels will appear at radial distances *radii* at the
        given *angle* in degrees.

        *labels*, if not None, is a ``len(radii)`` list of strings of the
        labels to use at each radius.

        If *labels* is None, the built-in formatter will be used.

        *rpad* is a fraction of the max of *radii* which will pad each of
        the radial labels in the radial direction.

        Return value is a list of tuples (*line*, *label*), where
        *line* is :class:`~matplotlib.lines.Line2D` instances and the
        *label* is :class:`~matplotlib.text.Text` instances.
