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()
    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()
