How to set colors for nodes in NetworkX?
提问by Gokhan Arik
I created my graph, everything looks great so far, but I want to update color of my nodes after creation.
我创建了我的图表，到目前为止一切看起来都很棒，但我想在创建后更新节点的颜色。
My goal is to visualize DFS, I will first show the initial graph and then color nodes step by step as DFS solves the problem.
我的目标是将 DFS 可视化，我将首先显示初始图形，然后在 DFS 解决问题时逐步显示颜色节点。
If anyone is interested, sample code is available on Github

All you need is to specify a color map which maps a color to each node and send it to nx.draw function. To clarify, for a 20 node I want to color the first 10 in blue and the rest in green. The code will be as follows:
您只需要指定一个颜色图，将颜色映射到每个节点并将其发送到 nx.draw 函数。澄清一下，对于 20 个节点，我想将前 10 个着色为蓝色，其余为绿色。代码如下：
G = nx.erdos_renyi_graph(20, 0.1)
color_map = []
for node in G:
if node < 10:
color_map.append('blue')
else:
color_map.append('green')
nx.draw(G, node_color=color_map, with_labels=True)
plt.show()
You will find the graph in the attached image
.
您将在附图中找到该图表。

Refer to node_colorparameter:
参考node_color参数：
nx.draw_networkx_nodes(G, pos, node_size=200, node_color='#00b4d9')
