Hello,
I have this marix:
M=matrix(ZZ,6,9,[[1,1,1,0,0,0,0,0,0],[0,0,0,1,1,1,0,0,0],[0,0,0,0,0,0,1,1,1],[-1,0,0,-1,0,0,-1,0,0],[0,-1,0,0,-1,0,0,-1,0],[0,0,-1,0,0,-1,0,0,-1]])and I am looking to get something like this:
How can I do it?
Hi,
If you just want the digraph, without the weights you can use
sage: D=DiGraph(M,format='incidence_matrix')If you want to incorporate weights, you can try something like
sage: A=Matrix(ZZ,[[0,0,0,1,2,3],[0,0,0,4,5,6],[0,0,0,7,8,9],[0,0,0,0,0,0],[0,0,0,0,0,0],[0,0,0,0,0,0]])
sage: D=DiGraph(A,format='weighted_adjacency_matrix')Thank you! I do no know if I am missing some package or something but I cannot make the graph 'behave' like the picture above.
If you want the vertex labels to appear as in your picture you might want to consider using the `relabel` method. For the edge labels to appear in the plot you can send an `edge_labels=True` argument to the `plot` method.
Thanks for the hand! I'll pay you a beer whenever I am in Canada!
