Networkx特定节点的标签 [英] Networkx specific nodes labeling

问题描述

我想绘制一个网络，但除了Cretin节点外，我希望它不被标记.

I want to draw a network and I want it to be unlabeled with the exception for cretin nodes.

我现在所拥有的是这样的:

What I have at the moment is something like this:

nx.draw(G, pos=pos, node_color='b', node_size=8, with_labels=False)

for hub in hubs:
     nx.draw_networkx_nodes(G, pos, nodelist=[hub[0]], node_color='r')

此刻的代码更改了集线器列表中节点的大小和颜色.我也想给它们加上标签.

The code at the moment changes the size and color of the nodes in the hubs list. I'd like to label them as well.

我试图添加label参数并将其值设置为中心名称.但这没用.

I tried to add the label argument and set its value to the hub name. but it did't work.

谢谢

推荐答案

从布拉的评论来看，解决方案非常简单

From Bula's comment the solution is quite easy

诀窍是在字典中设置标签，其中的键是节点名，值是您需要的标签.因此，仅标记集线器，代码将类似于以下内容:

The trick is to set the labels in a dictionary where the key is the node name and the value is the label you require. Therefore to label only the hubs, the code will be something similar to this:

labels = {}    
for node in G.nodes():
    if node in hubs:
        #set the node name as the key and the label as its value 
        labels[node] = node
#set the argument 'with labels' to False so you have unlabeled graph
nx.draw(G, with_labels=False)
#Now only add labels to the nodes you require (the hubs in my case)
nx.draw_networkx_labels(G,pos,labels,font_size=16,font_color='r')

我得到的是以下内容:

I got what I wanted which is the following:

我希望这会帮助像我这样的其他python/networkx新手:)

I hope this would help other python/networkx newbies like myself :)

再次感谢布拉(Bula)
