Thanks,
this helped me understand how it could work:
plot(gg, layout=cbind(V(gg)$x, 0))
The x-position is great. Now I am looking for "reasonable" y-values.
Reasonable for me means:
The plotted graph should look okay.The ideal y-values would be those
that give the vertices
positions (my x-value and any y-value) so that the plotted graph is
clearly arranged.
Is there an algorithm I should test?
Otherwise I will check if "reasonable" y-values might be produced by
assigning for instance
the mean of the weights for each vertex.
By the way, how do I get all edges (or weights) of a vertix?
Thanks
Hermann
