I'm not sure what you mean here? Do you want to move the A and B nodes further apart? If so, just insert empty columns between them. > > also how can i annotate the objects A and B ( i want to write their domain values ) something like: > [1,2,3] [4,5,6] > A B > One way (not the only one, I think) is to make each node a 2x1 array. Does this do what you want? \xymatrix{*++[F]{\begin{array}{c} [1,2,3]\\ A\end{array}}\ar@{-}[rrr]{(0,0),(1,1)} & & & *++[F]{\begin{array}{c} [4,5,6]\\ B\end{array}}} Paul
