          Share the formatoptions of this plotter with others
  
          This method shares the formatoptions of this :class:`Plotter` instance
          with others to make sure that, if the formatoption of this changes,
          those of the others change as well
  
          Parameters
          ----------
          plotters: list of :class:`Plotter` instances or a :class:`Plotter`
              The plotters to share the formatoptions with
          keys: string or iterable of strings
              The formatoptions to share, or group names of formatoptions to
              share all formatoptions of that group (see the
              :attr:`fmt_groups` property). If None, all formatoptions of this
              plotter are unshared.
