The graph indicates a change in velocity relative to our position. If one side of the galaxy is moving towards us (from -30 to -10 kpc), it means that side is rotating in our direction. Conversely, if the other side (from 10 to 30 kpc) is moving away, it indicates that side is rotating away from us.
