Then you are able to pick the time units along the axis and the difference between the graphs at the poing is the short pulse adder. Difficult to explain but easy to do. It is close enough that it runs very well. If it is a returnless system, I graph the offsets and flow at both ends of the table as well as the center and interpolate the rest.
