As states are defined (and applied) a line along the X-axis of the main plot will appear. The colors of this line represent the different states and times within the period of record when a given state is in effect (Figure 9). Details about assignment and changing of colors are provided in the “Color management” section of this manual.
When all time within the period of record has been assigned to a state, the colored line will appear continuous and represents a set of unpopulated flow recommendations.
