  """
  Autocorrelation plot for time series.
 
+ This method generates an autocorrelation plot for a given time series,
+ which helps to identify any periodic structure or correlation within the
+ data across various lags. It shows the correlation of a time series with a
+ delayed copy of itself as a function of delay. Autocorrelation plots are useful for
+ checking randomness in a data set. If the data are random, the autocorrelations
+ should be near zero for any and all time-lag separations. If the data are not
+ random, then one or more of the autocorrelations will be significantly
+ non-zero.
