I'm trying to plot a graph with labels on the edges as follows:
G = Graph(multiedges=True)
G.add_edges( [(0,1,'a'),(1,2,'b'),(2,3,'c'),(3,4,'b'),(4,0,'a')] )
H = G.plot(edge_labels=True, graph_border=True)
H.show()
Is it possible to color the edge labels, e.g. making the "a" red, "b" blue etc?
It is doable as follows:
sage: G.plot(color_by_label={'a':'red', 'b':'blue', 'c':'green'})
If you are lazy, you can let Sage decide the colors for you:
sage: G.plot(color_by_label=True)
Of course you can use the other options if needed:
sage: G.plot(edge_labels=True, graph_border=True, color_by_label={'a':'red', 'b':'blue', 'c':'green'})
