保存iGraph python數字？

Question

我使用的igraph使用igraph.plot（）來生成網絡圖，但我只能得到這些流行起來，沒有真正節省，而無需手動保存每個人物：

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() 

當我嘗試做以下，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') 

它保存一個空的圖片。有小費嗎？

igraph.plot不會創建matplotlib圖形，所以沒有什麼可以保存的（不像其他包，如networkx）。這應該工作：

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')
