World Position Routing: The yellow trace displayed in this plot is the measured position of the top stage and
the purple plot line is the commanded or desired position. The axis to be displayed on the scope - X, Y, Z,
Roll, Pitch, or Yaw - can be selected using the Position Index block (values between 0 and 5). The measured
position commands are generated by the forward kinematics.
