Re: [igraph] correlation between attributes in bipartite network

[Gábor Csárdi]

Simone,

I am not completely sure what you want to correlate. Can you simply
write down, what exactly would be on the two axes in your desired
plot?

Also, it helps, if you send some toy data or graph, or code that
creates toy data. Otherwise people might be reluctant to spend ten
minutes on making up some data. At least I am.

Best,
Gabor
