Follow-up Comment #2, bug #54896 (project octave):

Actually, this was part of the larger dataset

x =[1, 1, 2, 2, 2, 4, 4, 8, 8, 16, 32, 64]
y = [1.0, 2.0, 4.0, 8.0, 15.25, 16.0, 30.5, 32.0, 61.0, 122.0, 244.0, 488.0]

with which you get some edges, but last three points are hanging in the air,
instead I would expect to have parallel edges separating them.

Tried my first example in Matlab Live editor and it failed saying that points
are collinear, but this second one works fine showing parallel lines for last
four points, while in Octave they are absent.

(file #45293, file #45294)
