Non smooth plot, undesired points in chart.

Hello collegues,
I have a modell in motionview, and I locate an output of the torque applied in a rotational motion. The motion follows the next expression:
`STEP5(TIME,0,0,0.5,(185*3*(2*PI/40)))+STEP5(TIME,0.5,0,1,(-185*3*(2*PI/40)))+STEP5(TIME,1,0,1.5,(185*3*(2*PI/40)))+STEP5(TIME,1.5,0,2,(-185*3*(2*PI/40)))+STEP5(TIME,2,0,2.5,(185*3*(2*PI/40)))+STEP5(TIME,2.5,0,2.75,(-185*3*(2*PI/80)))`
When I plot the results of the torque, I obtain the attached chart, very irregular.
Do you know the root cause, and if it's possible to solve this undesirable result?
Thanks!
