Why didn't astronomers use this diagram to justify the decision?

Because unless there's some property unique to dwarf planets, you're still just using an arbitrary distinction

How much an object appears to move (from an observer on earth's pov) measured in something like arcseconds/year. Astronomy has all sorts of weird conventions from the last few centuries

>How much...
thx, so to speak kind of a measure of the distance.
neptune and uranus seem to have a good position relative to earth at the 'moment'.
in any case, these two are just a maximum factor of 3 closer to the earth as pluto while in this diagramm there are 5 orders of magnitude in between.
quite a lot.
so this is only sort of an apparent segregation by µ.
and looking at the masses on top of the graph this is an even distribution (in the orders).

The µ in OP's plot is most probably the 'planetary discriminator' coefficient proposed by Soter: The ratio of a candidate body's mass to the total mass of all other bodies sharing crossing similar orbital radii and with periods in the same order of magnitude (excluding comets).

okok

forget what I wrote here.
log(M) is ratio of mass to mass M of earth (m(candidate)/M; for earth log1 = 0)
log(m) seems to be more complicated and it must be connected to the orbital radius.
no clue here.
