我想使用networkx(如果您知道更好的框架,我也想采用其他框架)来创建节点位于固定位置的抓图。同时,图形的边缘不应重叠。
我之前的代码如下:
#!/usr/bin/env python3
import networkx as nx
import matplotlib.pyplot as plt
# Graph data
names = ['A', 'B', 'C', 'D', 'E']
positions = [(0, 0), (0, 1), (1, 0), (0.5, 0.5), (1, 1)]
edges = [('A', 'B'), ('A', 'C'), ('A', 'D'), ('A', 'E'), ('D', 'A')]
# Matplotlib figure
plt.figure('My graph problem')
# Create graph
G = nx.MultiDiGraph(format='png', directed=True)
for index, name in enumerate(names):
G.add_node(name, pos=positions[index])
labels = {}
for edge in edges:
G.add_edge(edge[0], edge[1])
labels[(edge[0], edge[1])] = '{} -> …Run Code Online (Sandbox Code Playgroud)
