如何使用python nrtworkx将图放大？

问题描述

生成图片太小，不能看清节点间连线，太过密集，望能给出解决方法

# _*_ coding:utf-8 _*_import matplotlib.pyplot as pltimport networkx as nxG = nx.DiGraph()#加载文件中边的关系with open(’bigdata.txt’) as f: lines = f.readlines()mylist = [line.strip().split() for line in lines] pos =nx.spring_layout(G)outlist = []for i in range(len(mylist)): a = mylist[i][0] for j in range(len(mylist[i])-1):outlist.append([a, mylist[i][j+1]])#加载边G.add_edges_from(outlist)nx.draw(G, with_labels=True, node_size=200,width=0.3, node_color=’r’, alpha = 0.7, edge_color=’black’,edge_vmin=2,edge_vmax=3)plt.savefig(’test1.png’)plt.show()

问题解答

建议网络图使用d3py,或者设置matplotlib的画布大小
