如何循环保存多个图？

Question

我试图在循环中保存多个绘图，但它会将它们相互绘制。我应该怎么办？

示例代码：

import pandas as pd
import seaborn as sns
data=pd.DataFrame({'a':[1,2,3,4,5,6],'b':[0,1,1,0,1,1],'c':[0,0,0,1,1,1]})
for i in ['b','c']:
    img=sns.boxplot(data.a, groupby=data[i])
    fig = img.get_figure()
    fig.savefig(i)

Answer 1

您需要清除循环中滚动的上一个图中的数据。这应该有效，注意fig.clf()每个循环的结尾：

import pandas as pd
import seaborn as sns
data=pd.DataFrame({'a':[1,2,3,4,5,6],'b':[0,1,1,0,1,1],'c':[0,0,0,1,1,1]})
for i in ['b','c']:
    img=sns.boxplot(data.a, groupby=data[i])
    fig = img.get_figure()
    fig.savefig(i)
    fig.clf()
