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'})Is it also possible to color parts of the label differently, e.g. instead of making "label a" completely red, would it be possible to make the substring 'label' red and 'a' green? Or is it possible to use LATEX /HTML code for this string formatting?
