networkx节点2D网格,Python

此种类型2D网格图,类似于棋盘等。

import networkx as nx
import matplotlib.pyplot as plt


def my_graph():
    G = nx.grid_2d_graph(4, 4)

    pos = nx.spring_layout(G, iterations=100)

    # nrows=2,ncols=2,index=1
    plt.subplot(2, 2, 1)
    nx.draw(G, pos, font_size=10, with_labels=True)

    # nrows=2,ncols=2,index=2
    plt.subplot(2, 2, 2)
    nx.draw(G, pos, node_color="yellow", node_size=50, with_labels=False)

    # nrows=2,ncols=2,index=3
    plt.subplot(2, 2, 3)
    H = G.to_directed()
    nx.draw(H, pos, node_color="blue", node_size=20, with_labels=False)

    # nrows=2,ncols=2,index=4
    plt.subplot(2, 2, 4)
    pos = dict((n, n) for n in G.nodes())
    labels = dict(((i, j), 'Phil') for i, j in G.nodes())
    nx.draw_networkx(G, pos=pos, labels=labels, font_size=8, font_color='white', node_color="red", node_size=350,
                     width=3)

    plt.axis('off')
    plt.show()
