   Plot of the cumulative frequency of a time Series.

   :param sim: Series with the simulated values.
   :type sim: pandas.Series
   :param obs: The pandas Series with the observed values.
   :type obs: pandas.Series
   :param ax: Matplotlib Axes instance to create the plot on. A new Figure and Axes is
              created when no value for ax is provided.
   :type ax: matplotlib.axes.Axes, optional
   :param \*\*kwargs: Optional keyword arguments, passed on to plt.subplots.
   :type \*\*kwargs: dict, optional

   :returns: **ax**
   :rtype: matplotlib.axes.Axes

   .. rubric:: Examples

   >>> obs = pd.Series(index=pd.date_range(start=0, periods=1000, freq="D"),
   >>>                 data=np.random.normal(0, 1, 1000))
   >>> ps.stats.plot_cum_frequency(obs)
