Re: [igraph] Draw vertices in a certain order

[Hugues François]

Hi,

Thanks again for the help. Even igraph is really powerfull, I'm unable to find 
where I'm doing something wrong... But the final result is far from what I 
expected (see attached file) even isomorphic returns 'TRUE'. I think I will 
give up for now. Does the "bug" has been reported since your last discussion 
about plotting order ?

Hi, here is an example that puts higher degree nodes last:
