I have noticed that as you change the vertex size, the arrows in directed graphs don't move away from the vertex. so if the vertex is large, then it compeletely covers the arrow. ( example below) is there a way to move the head of the arros in a directed graphs so that it's not covered by the vertex? maybe set it maybe few pixels away from the vertices by default or something... also is there a way to change the shape of the arrow head? maybe to shape different than a triangle. any and all thoughts are appreciated thank you in advance. sean g2 = Graph[{ {{1, 2}, EdgeStyle -> ThinDashed}, {{2, 3}, EdgeStyle -> ThinDashed}, {{3, 4}, EdgeStyle -> ThinDashed}, {{3, 5}}, {{5, 6}, EdgeStyle -> ThinDashed}, {{6, 2}}}, {{{0.5, 1.5}, VertexLabel -> AAA, VertexStyle\[Rule] Box[Normal], VertexLabelPosition\[Rule] LowerRight, VertexColor\[Rule] Normal}, {{0.5, 1.0}, VertexLabel -> BBB, VertexStyle\[Rule] Box[0.02], VertexLabelPosition\[Rule] UpperRight, VertexColor\[Rule] Line}, {{1.0, 1.0}, VertexLabel -> CCC, VertexStyle\[Rule] Box[0.1], VertexLabelPosition\[Rule] UpperRight, VertexColor\[Rule] Gray}, {{1.5, 1.0}, VertexLabel -> DDD, VertexStyle\[Rule] Box[0.05], VertexLabelPosition\[Rule] UpperLeft, VertexColor\[Rule] Normal}, {{1.0, 0.5}, VertexLabel -> EEE, VertexStyle\[Rule] Box[0.05], VertexLabelPosition\[Rule] UpperLeft, VertexColor\[Rule] Normal}, {{0.5, 0.5}, VertexLabel -> FFF, VertexStyle\[Rule] Box[0.05], VertexLabelPosition\[Rule] UpperRight, VertexColor\[Rule] Normal}}, EdgeDirection -> On]; ShowGraph[g2] GraphOptions[g2] __________________________________ Do you Yahoo!?
