如何分离图形的图像？

Question

我需要绘制这些完整的图，使单独图的边不相交并相互截断。我曾尝试在 matplotlib 中使用坐标，但没有成功。即代码：

import networkx as nx
import matplotlib.pyplot as plt


G=nx.Graph()
G.add_edge("1", "2")
G.add_edge("2","3")
G.add_edge("3","4")
G.add_edge("1","3")
G.add_edge("1","4")
G.add_edge("2","4")

pos = {1: (0, 0), 2: (1, 1), 3: (0, 1) , 4: (1, 0)}
        
F=nx.Graph()
F.add_edge("5", "6")
F.add_edge("6","7")
F.add_edge("7","8")
F.add_edge("5","7")
F.add_edge("5","8")
F.add_edge("6","8")

pos = {5: (10, 10), 6: (11, 11), 7: (10, 11) , 8: (11, 10)}

E=nx.Graph()
E.add_edge("9", "10")
E.add_edge("10","11")
E.add_edge("9","11")

pos = nx.random_layout(E)

Y=nx.Graph()
Y.add_node("12")

pos = nx.random_layout(Y)

nx.draw(G, with_labels = True, node_color = 'white')
nx.draw(F, with_labels = True, node_color = 'white')
nx.draw(E, with_labels = True, node_color = 'white')
nx.draw(Y, with_labels = True, node_color = 'white')

plt.savefig('labels.png')
plt.show()

结果

您创建了 pos 变量并多次覆盖它，但在任何时候都没有使用它。只需创建多个不重叠的绘图区域：

import networkx as nx
import matplotlib.pyplot as plt

G = nx.Graph()
G.add_edge("1", "2")
G.add_edge("2", "3")
G.add_edge("3", "4")
G.add_edge("1", "3")
G.add_edge("1", "4")
G.add_edge("2", "4")

pos_G = {"1": (0, 0), "2": (1, 1), "3": (0, 1), "4": (1, 0)}

F = nx.Graph()
F.add_edge("5", "6")
F.add_edge("6", "7")
F.add_edge("7", "8")
F.add_edge("5", "7")
F.add_edge("5", "8")
F.add_edge("6", "8")

pos_F = {"5": (10, 10), "6": (11, 11), "7": (10, 11), "8": (11, 10)}

E = nx.Graph()
E.add_edge("9", "10")
E.add_edge("10", "11")
E.add_edge("9", "11")

pos_E = nx.random_layout(E)
pos_E = {node: pos + 3 for node, pos in pos_E.items()}

Y = nx.Graph()
Y.add_node("12")

pos_Y = nx.random_layout(Y)
pos_Y = {node: pos + 5 for node, pos in pos_Y.items()}

nx.draw(G, pos_G, with_labels=True, node_color='white')
nx.draw(F, pos_F, with_labels=True, node_color='white')
nx.draw(E, pos_E, with_labels=True, node_color='white')
nx.draw(Y, pos_Y, with_labels=True, node_color='white')

# plt.savefig('labels.png')
plt.show()
