I have coordinates (x,y) of size n. Here x ,y coordinates are decision variables 

I am trying strict lexicographical ordering (x1,y1) > lex (x2,y2) i.e. x1>x2 or if x1=x2 then y1>y2.

This is logical constraint if x1>x2 is true then no need to add this constraint x1=x2 then y1>y2

Just guide me how to achieve this mathematical form

  The Knowledge Base article How do I model conditional statements in Gurobi? should be helpful.
