NetworkX中的二部图 [英] Bipartite graph in NetworkX

问题描述

B.add_nodes_from(a, bipartite=1)
B.add_nodes_from(b, bipartite=0)
nx.draw(B, with_labels = True)  
plt.savefig("graph.png")

我得到下图.如何使它看起来像适当的二部图?

I am getting the following figure. How can I make it look like a proper bipartite graph?

推荐答案

您可以执行以下操作，从每个分区的特定x坐标处绘制节点:

You could do something like this, to draw nodes from each partition at a particular x coordinate:

X, Y = bipartite.sets(B)
pos = dict()
pos.update( (n, (1, i)) for i, n in enumerate(X) ) # put nodes from X at x=1
pos.update( (n, (2, i)) for i, n in enumerate(Y) ) # put nodes from Y at x=2
nx.draw(B, pos=pos)
plt.show()

关键在于为nx.draw pos参数创建dict，即:

The key is creating the dict for the the nx.draw pos parameter, which is:

以节点为键，位置为值的字典.

A dictionary with nodes as keys and positions as values.
