High jerks in acceleration values

$

Hello, I am using ros-kinetic version on ubuntu 16.04 . I am sending trajectories from MoveIt to ros control. To analyse trajectory, I compared trajectory given by MoveIt with the output of ros control and found that acceleration profile of ros control output has so many jerks and overshoots and is not following MoveIt trajectory. I have subscribed from **/position_trajectory_controller/command** to get output from ros control. I have plotted the trajectory using octave in both cases. Can someone explain why this is happening? Thanks in advance
