Hi,
I'm using the code below to fix the position of a root vertex. I'm developing an application and I wanna make sure that the root vertex is always located in the same place.
g = Graph() v_pin = g.new_vertex_property("bool") v = g.add_vertex() v_pin[v] = True #root vertex ... pos = sfdp_layout(g, pin=v_pin) graph_draw(g, ...)
I suppose it's working, but how I can confirm which one is the root vertex in my result?
There are many ways: You can change the shape, size, and color of the vertices to your liking. It is all described in the documentation. For instance, to change the color of the root you would do: c = g.new_vertex_property("int") c[root] = 1 graph_draw(g, vertex_fill_color=c) Best, Tiago -- Tiago de Paula Peixoto <tiago@skewed.de>
