Plot Description:

This plot presents the time series of trailing X number of day departures evaluated every Y days forward in time. The departures are expressed in terms of standard deviation (sigma) by comparing the current period against the same period of dates back through the period of record. The evaluation points are connected by arrows to express the evolution of the departures. Since the plot is bounded by physical processes, the plot tends to cycle. In economics, a classic comparable plot to this one is of suply vs demand.
