我使用NetworkX和holoview创建了一个图形,并且希望为节点使用不同的颜色。这里的代码: (首先,请安装python库:
import pandas as pd
# Ouverture fichier excel
data = pd.read_excel (r'C:\Yourpath\Sedan_jour_00.xlsx')
data = data[["commune", "rao_libelle_voie", "rao_titre_point", "adr_l1_name"]][0:20]
xlsx文件的Google表格链接(在本地下载,并替换为路径):
import hvplot.networkx as hvnx
import matplotlib.pyplot as plt
import networkx as nx
import holoviews as hv
from bokeh.models import HoverTool
G = nx.balanced_tree(3, 2)
traite = set()
#for L1 in data:
for index, L1 in data.iterrows():
L1 = L1.values
for l in range(0,len(L1)-1):
if L1[l] not in traite:
G.add_node(L1[l])
traite.add(L1[l])
if L1[l+1] not in traite:
G.add_node(L1[l+1])
G.add_edge(L1[l],L1[l+1])
traite.add((L1[l],L1[l+1]))
G = hvnx.draw(G, node_size=1500, node_color='#33D1FF', inspection_policy="edges")
hvnx.show(G)
G.opts(tools=[HoverTool(tooltips=[('end', '@end_values')])])
hvnx.show(G)
结果还可以,但是我想在每个节点上使用不同的颜色 (我没有在这里进行试用,那没有用);
这是我想要的结果(用油漆绘制的绘图):
