python作图

编程小白艾雪儿

想要在一个图里画多个折线图，分开是ok的，画在同一张图里就出现了混线

1. plt.figure()
   
2. 
   
3. for i in set(df['Indcd']):
   
4.     print(i)
   
5.     data = df[df['Indcd'].isin([i])]
   
6.     data = data.drop_duplicates(subset='Trdmnt')
   
7.     plt.plot(data['Trdmnt'], data['Weight'])

1. plt.figure()
   
2. d1 = df[df['Indcd'].isin([1])]
   
3. d1 = d1.drop_duplicates(subset='Trdmnt')
   
4. plt.plot(d1['Trdmnt'], d1['Weight'])
   
5. plt.figure()
   
6. d2 = df[df['Indcd'].isin([2])]
   
7. d2 = d2.drop_duplicates(subset='Trdmnt')
   
8. plt.plot(d2['Trdmnt'], d2['Weight'])
   
9. plt.figure()
   
10. data = df[df['Indcd'].isin([3])]
    
11. data = data.drop_duplicates(subset='Trdmnt')
    
12. plt.plot(data['Trdmnt'], data['Weight'])
    
13. plt.figure()
    
14. data = df[df['Indcd'].isin([4])]
    
15. data = data.drop_duplicates(subset='Trdmnt')

20. plt.plot(data['Trdmnt'], data['Weight'])
