pd.DataFrame.box绘图不兼容钯铜

Question

样本代码：

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))

除了方框图外，一些文本会出现在绘图周围。如何从绘图中删除文本？在

Answer 1

您可以尝试通过^{}创建新列c，因为在^{}参数{}可以是列：

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')
