why t3 , t8 plane ?
in sampling about the flavor u,d,s ...we use the t3, t8 generators amd plot all the possible combinations of their eigen values ....and then define u ,d , s....
i want 2 ask that why specifically these 2 SU(3) generators are used t o
I have vague answers 2 this question but m not satisfied with those ....
plz help me !

You posed a bit of a vague question, you might want to reformulate it.
But I think the answer you are looking for is that that the up and down quark are much better symmetry partners (to a great approximation they are eigenstates of isospin symmetry, which the mass of the strange quark spontaneously breaks).

It seems sensible to choose generators (mesons) in a way that the inclusion SU(2) < SU(3) < SU(4) <... is explicit, but I am not sure if practicioners can use this rationale.
