        Set the formatter of the major ticker.

        In addition to a `~matplotlib.ticker.Formatter` instance,
        this also accepts a ``str`` or function.

        For a ``str`` a `~matplotlib.ticker.StrMethodFormatter` is used.
        The field used for the value must be labeled ``'x'`` and the field used
        for the position must be labeled ``'pos'``.
        See the  `~matplotlib.ticker.StrMethodFormatter` documentation for
        more information.

        For a function, a `~matplotlib.ticker.FuncFormatter` is used.
        The function must take two inputs (a tick value ``x`` and a
        position ``pos``), and return a string containing the corresponding
        tick label.
        See the  `~matplotlib.ticker.FuncFormatter` documentation for
        more information.
