另附上我简单的画折线图代码和图：

import matplotlib.pyplot as plt 
 
if __name__ == '__main__': 
  x = [20,50,100,150,200,300,400,600,1000] 
  y1=[1,2,3,4,5,6,7,8,9]  
  plt.figure(figsize=(8,4.9)) 
  plt.plot(x,y1,label = "$example$",color = 'r',marker = "+",linewidth=1) 
  plt.xlabel("number") 
  plt.ylabel("time") 
  plt.title("-") 
  plt.legend() 
  plt.show()
