using draw_networkx(), How to show multiple drawing windows?

The following code will create only one window at a time, the second window will only show开发者_Python百科 when the first one is closed by the user.

How to show them at the same time with different titles?

nx.draw_networkx(..a..)
nx.draw_networkx(..b..)

It works the same as making other plots with Matplotlib. Use the figure() command to switch to a new figure.

import networkx as nx
import matplotlib.pyplot as plt

G=nx.cycle_graph(4)
H=nx.path_graph(4)

plt.figure(1)
nx.draw(G)
plt.figure(2)
nx.draw(H)

plt.show()

You can use matplotlib and a grid to show multiple graphs:

#!/usr/bin/env python
"""
Draw a graph with matplotlib.
You must have matplotlib for this to work.

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

plt.subplot(221)
nx.draw(G,pos,font_size=8)

plt.subplot(222)
nx.draw(G,pos,node_color='k',node_size=0,with_labels=False)

plt.subplot(223)
nx.draw(G,pos,node_color='g',node_size=250,with_labels=False,width=6)

plt.subplot(224)
H=G.to_directed()
nx.draw(H,pos,node_color='b',node_size=20,with_labels=False)

plt.savefig("four_grids.png")
plt.show()

Code above will generates this figure:
