status of an operator in state chart

Hi:

I have an operator serving two machines, and I want to know his status over time. I used a state plot to do the job. The result is as follows.

However, the status does not match the working condition of the operator. The state pie chart shows his utilization is about 25.89%, but the time plot shows only a few percentages of his time is working. Can I change the state time plot to reflect the actual working (utilization) condition? The flexsim program is attached. Primer_2-5B-compare.fsm

Your "State vs. Time for Operator" chart plots the content of the operator over time. So it is essentially showing the time in which the operator is travelling with an item.

The proper chart to showcase an object's state over time would be a "State Gantt" chart.

Or you build your own Statistics Collector that flips between 0 and 1 depending on whether the operator is in the "utilize" state or not (by listening to the state change event).
