networkx绘图示例

def drawGraph(fg, title='weighted_graph'):
import matplotlib.pyplot as plt
import networkx as nx

pos = nx.spring_layout(fg)
nx.draw_networkx_nodes(fg, pos, node_shape='.', node_size=20)
nx.draw_networkx_edges(fg, pos)
nx.draw_networkx_labels(fg, pos)
nx.draw_networkx_edge_labels(fg, pos, edge_labels=nx.get_edge_attributes(fg, 'weight'))

plt.savefig(os.path.join(CWD, '../PGT/middlewares/' + title + '.png'))
plt.show()
