我正在尝试使用NetworkX1.9.1和wxPython2.9.2.4在10.10.2Mac上可视化网络，而我的Python版本是Python2.7.6。
我使用以下代码成功地可视化网络：
G = nx.random_graphs.barabasi_albert_graph(100, 1)
nx.draw(G)
plt.show()
但是当我尝试将NetworkX与wxPython一起使用时，我遇到了一些麻烦。
代码如下：
import networkx as nx
import matplotlib.pyplot as plt
import wx
class MyFrame(wx.Frame):
def __init__(self):
wx.Frame.__init__(self, None, -1, title='Test')
bt = wx.Button(self, label='bt')
bt.Bind(wx.EVT_BUTTON, self.Onbt)
def Onbt(self, e):
G = nx.random_graphs.barabasi_albert_graph(100, 1)
nx.draw(G)
plt.show()
app = wx.App()
frame = MyFrame()
frame.Show()
app.MainLoop()
单击按钮时出现错误：

wxPython无法与pylab / pyplot一起使用，因为它们都有自己的主循环。您应该让pyplot执行主循环而不是wxPython。请参阅this stackoverflow post和that matplotlib example。您会在两个示例中都注意到有一个self.axes/axes1对象（并且没有pyplot。
根据the NetworkX doc，您可以将matplotlib Axes对象传递给draw函数，该函数应生成您的图（未经测试）
