Matplotlib获取不规则形状

Question

This displays a node which is a figure using networkx and matplotlib :

import networkx as nx
import matplotlib.pyplot as plt
G = nx.Graph()
n = "%%%%% \n% % % \n%%%%%"
print n
G.add_node(n)
nx.draw(G)
plt.show()

print n displays:

%%%%% 
% % % 
%%%%%

plt.show() displays:

%%%%% 
 %%% 
%%%%%

The data is very large so i can't edit n and rearrange it for desired output. How can I code such that both the shapes are equal?

Answer 1

You can set n again with a differently formated string:

import networkx as nx
import matplotlib.pyplot as plt
G = nx.Graph()
n = "%%%%% \n% % % \n%%%%%"
print n
n = n.replace(" ", "   ")
G.add_node(n)
nx.draw(G)
plt.show()

And you will get the following figure and output:

%%%%% 
% % % 
%%%%%

Or is there any reason that you did not specify why this does not work?
