How do I display the occupancy rate through time in the restaurant sample model? For example, if every time a group of 4 persons sits in a table with 4 chairs through all the simulation time, the occupansy rate will be of 100%. Or 4 groups of people sat in the same table, if 2 groups were of 4 personse and the other 2 groups were of 2 persons, the total occupancy rate will be of 75%.
