В следующем коде я хотел бы нарисовать линию от последнего ромба до самого верхнего ромба, как показано в ascii-art ниже.

Можете ли вы показать мне, как получить вышеуказанное расположение? Также, как мне выровнять circle2по горизонтали с setloadavg?
С моим текущим кодом вертикальные линии накладываются друг на друга. Мой вывод из кода tex выглядит так:
