plot_isoredshifts
=================

.. py:method:: luminet.black_hole.BlackHole.plot_isoredshifts(redshifts=None, order=0, ax=None, **kwargs) -> matplotlib.axes.Axes

   Plot isoredshifts for a list of redshift values

   :Parameters: * **redshifts** (*List[float]*) -- list of redshift values
                * **kwargs** (*optional*) -- additional keyword arguments for the :meth:`luminet.isoredshift.Isoredshift.plot` method.
                * **order** (*int*) -- The order of the image to plot siofluxlines for. Default is :math:`0`.
                * **ax** (:class:`~matplotlib.axes.Axes`, optional) -- Axes object to plot on.
                  Useful for when you want to plot multiple things one a single canvas.

   Example::

       from luminet.black_hole import BlackHole

       bh = BlackHole()
       redshifts = [-.2, -.1, 0., .1, .2, .3, .4]
       ax = bh.plot_isoredshifts(redshifts, c='white')
       ax = bh.disk_apparent_inner_edge.plot(ax=ax, c='white')

   .. image:: /../_static/_images/isoredshifts.png
      :align: center

   :returns: :py:class:`~matplotlib.axes.Axes` -- The plotted isoredshifts.
