Plotting can track up to 3 sources of information. The Normalized result
of Input A and Input B as well as Equation can be used to form a
graphical plot and be saved as a spreadsheet. Each source has a user-
configurable low and high threshold. These thresholds can be the same as
applied to one of the outputs or other significant values.
Each input source also has a Span number associated with it. This is an
output from the Plotting tool and is not user-configurable. Span keeps a
running number when Plotting is active of the difference between the
maximum and minimum values for each input source. The result is SPC-
type information about the process being monitored. Span can be reset by
