@tabisso666 - The graph at right plots distance between the red dot and the blue dot as a function of time. (In other words, the graph shows length of the green rod as a function of time.) It's basically a little joke - because the usual interpretation of this distance-time graph at right is that something is moving at a constant speed, then sitting still, then moving at a constant speed once more. In any case, this is not a depiction of any real process. I made up the trajectories.
