[英]Plot a connectivity graph with adjacency matrix and coordinates list in python
I have a set of points (x,y) coordinates and also adjacency matrix which gives details of connectivity.我有一组点 (x,y) 坐标以及提供连接细节的邻接矩阵。 I want to plot the physical coordinates with the given connectivity.我想用给定的连通性绘制物理坐标。 I know networkx is useful to create a connectivity graph and scatter plot plots the physical coordinates.我知道networkx可用于创建连接图和散点图绘制物理坐标。 But what I want is both.但我想要的是两者兼而有之。
You can plot both coordinates and connectivity with Networkx
.您可以使用Networkx
绘制坐标和连通Networkx
。
import networkx as nx
import numpy as np
pos = np.random.rand(10, 2) #coordinates, (x, y) for 10 nodes
connect = [tuple(np.random.random_integers(0, 9, size=(2))) for x in range(8)] #random connections
#creation of the graph
graph = nx.Graph()
#adding nodes/connections in the graph
for node in range(len(pos)):
graph.add_node(node)
graph.add_edges_from(connect)
#plot of the nodes using the (x,y) pairs as coordinates
nx.draw(graph, [(x,y) for x,y in pos], node_size=50)
