nd the arrow crossing.
        head_width : float, default: 10
            Width of arrow head, sent to `.ArrowStyle`.
        head_length : float, default: 15
            Length of arrow head, sent to `.ArrowStyle`.
        tail_width : float, default: 2
            Width of arrow tail, sent to `.ArrowStyle`.
        text_props, arrow_props : dict
            Properties of the text and arrows, passed to `.TextPath` and
            `.FancyArrowPatch`.
        **kwargs
            Keyword arguments forwarded to `.AnchoredOffsetbox`.

        Attributes
        ----------
        arrow_x, arrow_y : `~matplotlib.patches.FancyArrowPatch`
            Arrow x and y
        text_path_x, text_path_y : `~matplotlib.text.TextPath`
            Path for arrow labels
        p_x, p_y : `~matplotlib.patches.PathPatch`
            Patch for arrow labels
        box : `~matplotlib.offsetbox.AuxTransformBox`
            Container for the arrows and labels.

        Notes
        -----
        If *prop* is passed as a keyword argument, but *fontproperties* is
        not, then *prop* is assumed to be the intended *fontproperties*.
        Using both *prop* and *fontproperties* is not supported.

        Examples
        --------
        >>> import matplotlib.pyplot as plt
        >>> import numpy as np
        >>> from mpl_toolkits.axes_grid1.anchored_artists import (
        ...     AnchoredDirectionArrows)
        >>> fig, ax = plt.subplots()
        >>> ax.imshow(np.random.random((10, 10)))
        >>> arrows = AnchoredDirectionArrows(ax.transAxes, '111', '110')
        >>> ax.add_artist(arrows)
        >>> fig.show()

        Using several of the optional parameters, creating downward pointing
        arrow and high contrast text labels.

        >>> import matplotlib.font_manager as fm
        >>> fontprops = fm.FontProperties(family='monospace')
        >>> arrows = AnchoredDirectionArrows(ax.transAxes, 'East', 'South',
        ...                                  loc='lower left', color='k',

        ...                                  text_props={'ec':'w', 'fc':'k'},
