在python中保存plot savefig时出现问题

Question

我没有找到如何使用那种代码savefig，表的类型是DataFrame

table=pd.DataFrame(ycon[att[0]])        
table[att[0]]=pd.to_numeric(table[att[0]],downcast='float',errors='coerce')
table.plot()
```

Answer 1

table.plot返回matplotlib.pyplot.axes对象

table=pd.DataFrame(ycon[att[0]])        
table[att[0]]=pd.to_numeric(table[att[0]],downcast='float',errors='coerce')
ax = table.plot()
fig = ax.get_figure()
fig.savefig('/path/to/figure.pdf')
