Wikipedia's has a decent article on Plutinos, the set of trans-Neptunian objects which are at or near the 3:2 resonance with Neptune, of which Pluto is the longest-known and most famous member.
About halfway down the article is an image of the orbits of Orcus, Pluto, Neptune, Uranus, and Jupiter, represented in a rotating reference frame around the sun that has a period of one Neptune Orbit.
The motions of Orcus and Pluto in a rotating frame with a period equal to Neptune's orbital period (holding Neptune stationary.)

From the Image Description:
The motion of Orcus and Pluto in a rotating frame with a period equal
to Neptune's orbital period. (Neptune is held stationary.) Orcus is a
plutino in a 2:3 mean motion resonance with Neptune. Pluto is grey and
Orcus is red. Neptune is the white (stationary) dot at 5 o'clock.
Uranus is blue, Saturn yellow, and Jupiter red. There are 41 frames
each having 3*164.8 years (3 times Neptunes orbital period).
In the fully animated version, the total timespan is roughly 20,000 years and the animation accounts for the precession of the orbits of Orcus and Pluto relative to Neptune over that period.
