График для представления длины очереди ко 2 оборудованию
Для наглядности можно графически представить некоторые параметры функционирования системы.
Допустим, мы хотим представить на всем периоде моделирования количество изделий, обработанных на втором виде оборудования.
Для начала должным образом заполним окно Edit Plot Window:
