Details

A cycle plot is a graphical method invented to study teh behaviour of a seasonal time series. The seasonal component of a univariate series is graphed. First the January values are graphed for successive years, then the February values and so forth. For each monthly subseries the mean of the values is portrayed by a horizontal line.
