The n-point vacuum expectation value is written as the "mass"-superposition of the integral whose integrand is the product of the two-point Δ^+ and Δ^<(1)> functions. In the three-point case, it is compared with the graph-theoretical representation previously introduced. For n-^^>4, the new representation has no relation consistent with the graph in position space, but it is found that the so-called DANAD-surface can be derived in quite a graph-theoretical manner.
