Is there an 'animation trajectory'as in v2.4?

I’m doing a short complex motion where the result is affected by many axis of rotation but the viewer must see a smooth curve, so I have to correct it frame-by-frame -but I can’t be sure of the exact curve without some helpful feedback.
Version 2.4 had “animation trajectory” where it could draw a path that represented the object’s motion.
Is there something equivalent, or a plugin etc?

‘Motion Paths’ panel in the object settings

Thanks Richard, that is of tremendous help!
