Hi, here is a simple solution using a counter: count = 1; g = LayeredGraphPlot[{1 -> 2, 1 -> 3}, EdgeRenderingFunction -> ({Thickness[0.001 count++], Arrow[#1]} &)] However, there is a hitchup. The EdgeRenderingFunction is called twice on every edge (I do not know why). To prevent drawing each edge twice with different thickness, we may use a function that remembers its values: count=1; Clear[getThickness]; getThickness[d_]:=getThickness[d]=0.004 count++; g=LayeredGraphPlot[{1->2,1->3},EdgeRenderingFunction->({Thickness[getThickness[#1]],Arrow[#1]}&)] hope this helps, Daniel Gaudium wrote: > Hello all, I created a graph with edges {1->2,1->3,2->4,2->5}.
