Hello, I wanted to manipulate a graph (removing/adding vertice) but keeping the general structure with option save_pos . Here is a little example to illustrate: gg=Graph() gg.add_cycle(range(5)) gg.plot(save_pos=True)
Then I delete vertex 1 and add it again, stupid example. gg.delete_vertex(1) gg.add_path([0,1, 2]) gg.plot() Now vertex 1 was added at a completely random position. For more complex graphs the result looks terrible. Could it be possible that in the case positions of known vertice are saved, positions of new vertice are optimized as it's the case when nothing was saved?
