Dear All,

I have a collection of 3 graphs

vRF[pos_, name_] := {White, EdgeForm[Black], Disk[pos, .1], Black,
  Text[name, pos]}

g1 = GraphPlot[{{1 -> 1, "2"}, {1 -> 2, "12"}, {2 -> 1, "9"}, {2 -> 2,
     "2"}, {3 -> 2, "6"}, {3 -> 3, "5"}, {1 -> 3, "15"}, {3 -> 1,
    "9"}}, DirectedEdges -> True, SelfLoopStyle -> .2,
  Method -> "CircularEmbedding", VertexRenderingFunction -> vRF];

g2 =
  GraphPlot[{{1 -> 2, "12"}, {2 -> 1, "9"}, {3 -> 2, "6"}, {3 -> 3,
    "3"}, {1 -> 3, "15"}, {3 -> 1, "9"}}, DirectedEdges -> True,
  SelfLoopStyle -> .2, Method -> "CircularEmbedding",
  VertexRenderingFunction -> vRF];

g3 =
 GraphPlot[{{1 -> 2, "4"}, {2 -> 1, "3"}, {3 -> 2, "2"}, {3 -> 3,
    "1"}, {1 -> 3, "5"}, {3 -> 1, "3"}}, DirectedEdges -> True,
  SelfLoopStyle -> .2, Method -> "CircularEmbedding",
  VertexRenderingFunction -> vRF];

If I combine these with

Row[{g1,g2,g3}]

I get (almost) exactly what I want. However the sizing is wrong and I
cannot scale the output as a whole since it is not a single graphics
directive. To get this as a single Graphics object I use

GraphicsRow[{g1,g2,g3}]

but this yields something very different from the Row command. The
graphs are not visible at all.

I am using Mathematica 8.0.0 on Mac OS X.

I have had this problem once before but cannot remember what I did to fix it.

Anyone have any ideas?

Yours,

Alistair Windsor
