問題描述

生成圖片太小，不能看清節(jié)點(diǎn)間連線，太過密集，望能給出解決方法

# _*_ coding:utf-8 _*_import matplotlib.pyplot as pltimport networkx as nxG = nx.DiGraph()#加載文件中邊的關(guān)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]])#加載邊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()

問題解答

建議網(wǎng)絡(luò)圖使用d3py,或者設(shè)置matplotlib的畫布大小
