当显示包含沿曲线或线探测器的数量分布的图形时，显示当前时间层的值。 This time layer can be changed on the "Edit Bar" without having to close the graph window, see Time Layers.
It is also possible to start the flow animation, then the curve displayed in the graph automatically changes according to the time layers. The graph also allows you to display all curves (for all time levels at once).
