How to get the plot over line in a time average

I got a CFD result which is transient, so I want to get a time averaged result in 10s. But in the meanwhile, I want to display the pressure along a line.

Usually I select the cells and plot the time average by “plot selection over time”
But I don’t know how to draw along the line and simultaneously plot over time.

Is there anybody know how to achieve that? Thanks a lot!

I’m not totally sure what you are trying to do. Are you trying to take the values plotted on the line, average those values on the line, and then plot that average as it changes over time?

If so, you just do a Plot Over Line and then do a Plot Data Over Time on the line plot.
