保存iGraph python数字？

Question

我使用的igraph使用igraph.plot（）来生成网络图，但我只能得到这些流行起来，没有真正节省，而无需手动保存每个人物：

def testplot(graph): 
    graph.vs['label'] = graph.vs['name'] 
    x = plot(graph, vertex_size=[a/5 for a in graph.betweenness()], 
      layout = graph.layout('grid')) 
    x.show() 

当我尝试做以下，其中plt是matplotlib：

def testplot(graph, name): 
    graph.vs['label'] = graph.vs['name'] 
    igraph.plot(graph, vertex_size=[a/5 for a in graph.betweenness()], 
       layout = graph.layout('grid')) 
    plt.savefig(name + '_allyBetweenness.png') 

它保存一个空的图片。有小费吗？

igraph.plot不会创建matplotlib图形，所以没有什么可以保存的（不像其他包，如networkx）。这应该工作：

def testplot(graph, name): 
    graph.vs['label'] = graph.vs['name'] 
    out = igraph.plot(graph, vertex_size=[a/5 for a in graph.betweenness()], 
         layout = graph.layout('grid')) 
    out.save(name + '_allyBetweenness.png')
