it is easier to plot your values when all are multiplied
by eg 1000. The axes label, however, can then have an additional
marker like $\cdot10^{-3}$

all are in a queue like x y z x y z x y z ... and you can
scan all values if they are in a min -- max intervall and
kill a x y z triple with the pop command, like I already
showed.

I gave you an example, how you can test for a minimal x value.
It is the same for y and z.
x y z x y z x y z
to rotate the last three you can use 3 1 roll, then
you have x y z x y z z x y, with -1 it's the other way
round.
x y z x y z z x y dup
is then
x y z x y z z x y y
and you can test for a vlue
x y z x y z z x y y 0.001 lt { delete the record and update m }
{ roll back to get x y z } ifelse
in the end you have values only in your given intervals
