如何在循环中保存多个绘图? [英] How to save multiple plot in a loop?

问题描述

我试图在一个循环中保存多个绘图，但它会将它们相互绘制.我该怎么办?

I tried to save multiple plot in a loop, but It draw them over each other. what should I do?

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)

推荐答案

您需要清除循环中滚动的上一个图形中的数据.这应该可以工作，注意 fig.clf() 作为每个循环的结束:

You need to clear the data from the previous figure which is rolling over in the loop. This should work, noting fig.clf() as the end of each loop:

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()
