A locus is a set of points satisfying a certain condition.
So what are you conditions?
There are a lot of ways an arbitrary grouping can be made from a larger 
set. What should determine if any given point should belong to group 1 
or 2 or N?

It is hard to solve a problem that is under defined, unless one makes up 
arbitrary constraints to satisfy the problem.
