The second bar of the Input Viewer

Does anyone know what is the second bar of the Input Viewer (see video)? If I move the pedals all the way to the left or right, the bar goes to zero. When I start to move my collective up, it goes crazy and starts to jump up and down.

Throttle, it’s bouncing around due to the governor.

Thanks, makes sense, but what is the connection with the pedals and the throttle? Why the bar goes down when the pedals are pushed to the extreme position?
