如何在networkx中自定义边缘标签的显示?

问题描述

我创建了一个具有边属性(例如r，例如r=23)的图.

I create a graph with edge attributions (say r, such as, r=23).

如何仅使用值23而不是{'r':'23'}显示边缘标签.

How do display edge labels only with the values, 23 instead of {'r':'23'}.

相关的源代码如下:

# build a graph
G.add_edge(u, v, r=value)

# plot the graph
pos = nx.spring_layout(G, scale=2)

nx.draw(G, pos)

edge_labels = nx.get_edge_attributes(G,'r')
nx.draw_networkx_edge_labels(G, pos, labels = edge_labels)

plt.savefig(out_file)

推荐答案

命令draw_networkx_edge_labels需要参数edge_labels而不是`labels.

The command draw_networkx_edge_labels needs the argument edge_labels rather than `labels.

因此您需要将nx.draw_networkx_edge_labels(G, pos, labels = edge_labels)更改为nx.draw_networkx_edge_labels(G, pos, edge_labels = edge_labels)
