Hello!
I would like to draw a simple graph G and its complement ¯G. I was asked to make the drawing such that it is evident that the drawings are complementary. More precisely I was advised to draw G and ¯G such that the coordinates of the vertices of G are the same as the one for ¯G.
What would be an easy way to accomplish this in Sage?
Thank you
With g.plot(save_pos = True) the layout used by Sage in the plot is saved in g. You can obtain it by doing g.get_pos() and give them to another graph with h.set_pos(g.get_pos()).
sage: g = graphs.KneserGraph(5,2)
sage: g.show(save_pos=True)
sage: g2 = g.complement()
sage: g2.set_pos(g.get_pos())
sage: g2.show()Asked: 11 years ago
