Vijay,
I believe all you have to do is (say you are in a 2D model) add two Domain Point Probes (right click on Definitions under [FileName] > Model(#) > Definitions). In one Point Prove Expression, set it equal to V; in the other, set the expression equal to V - mod1.ppb1 (or whatever the probe is). Then you can plot mod1.ppb2 as a function of whatever you like. I believe that this will get you what you want. There may be other ways to do this using a line, and then finding the potential distribution along that line. There is a very detailed explanation of this in the help documents as well.
Good luck,
John

Hi John
As you say, its better to use a boundary than a 2nd order (down) entity (as a point or edge in 3D), as you might have singularities on calulating flux around a singe point/vertex/edge
