[igraph] plotting vertices in reference to a x-axis

[Hermann Norpois]

Dear list,

I wish to apologise for my first clumsy question. Second trial:

I have an igraph object gg (see below) and I want the vertices being plotted in the order of x (that goes from 1 to 9) in reference to a x-axis.
How do I create a x-axis and how can I plot my vertices in relation to this x-axis?
Can you please give me a hint how this might work.

I started with
>  plot (gg, edge.width=(E(g)$weight)^4)

but I did not find a way to include any x-axis information.

Thanks
Hermann
