python - pd.DataFrame.boxplot 与 pd.cut 不兼容

Question

示例代码:

import pandas as pd
import numpy as np
sample = pd.DataFrame({"a":[1,2,3,1,2,3,1,2,3], "b":np.random.uniform(0,1,9)})

sample.boxplot(column="b", by=pd.cut(sample.a, bins=2))

除了箱形图图片，一些文本出现在图的周围。如何从图中删除文本？

Answer 1

您可以尝试通过cut 创建新列c ，因为在 DataFrame.boxplot参数 by 可以是 column:

by : string or sequence

Column in the DataFrame to group by

import pandas as pd
import numpy as np

sample = pd.DataFrame({"a":[1,2,3,1,2,3,1,2,3], "b":np.random.uniform(0,1,9)})

sample['c'] = pd.cut(sample.a, bins=2)
sample.boxplot(column="b", by='c')
