How to display relative flow velocity vectors in fluent? Why the rotational velocity disappeared?

For example, when I am using single reference frame to simulate a rotating cylinder,I set the fluid domain a rotational speed (rad/s), set the cylinder as moving wall, relative speed "0" to adjcent cell,the same rotational direction as the fluid domain +1 for X. After iteration, then go to the display vectors, why the flow direction is like no rotational speed at all???? I tried relative velocity in the down-menu, but no difference...

Thanks.

I attached pics here:
