        Add an arrow to the axes.

        Call signature::
        Draws arrow on specified axis from (`x`, `y`) to (`x` + `dx`,
        `y` + `dy`). Uses FancyArrow patch to construct the arrow.

        Parameters
        ----------
        x : float
            X-coordinate of the arrow base
        y : float
            Y-coordinate of the arrow base
        dx : float
            Length of arrow along x-coordinate
        dy : float
            Length of arrow along y-coordinate

        Returns
        -------
        a : FancyArrow
            patches.FancyArrow object

           arrow(x, y, dx, dy, **kwargs)
        Other Parameters
        -----------------
        Optional kwargs (inherited from FancyArrow patch) control the arrow
        construction and properties:

        Draws arrow on specified axis from (*x*, *y*) to (*x* + *dx*,
        *y* + *dy*). Uses FancyArrow patch to construct the arrow.
        %(FancyArrow)s

        Notes
        -----
        The resulting arrow is affected by the axes aspect ratio and limits.
        This may produce an arrow whose head is not square with its stem. To
        create an arrow whose head is square with its stem, use
            ax.annotate("", xy=(0.5, 0.5), xytext=(0, 0),
                arrowprops=dict(arrowstyle="->"))

        Optional kwargs control the arrow construction and properties:
