使用 pandas 的方框图

问题描述

正在尝试绘制 pandas 数据框的框图，但x轴列名称似乎不清楚。

import matplotlib.pyplot as plt
pd.set_option('display.mpl_style', 'default')
fig, ax1 = plt.subplots()
%matplotlib inline
df.boxplot(column = ['avg_dist','avg_rating_by_driver','avg_rating_of_driver','avg_surge','surge_pct','trips_in_first_30_days','weekday_pct'])

下面是输出

如何修复此问题以使x轴列看起来清晰

解决方案

我认为您需要参数rot：

cols = ['avg_dist','avg_rating_by_driver','avg_rating_of_driver',
        'avg_surge','surge_pct','trips_in_first_30_days','weekday_pct']

df.boxplot(column=cols, rot=90)

示例：

np.random.seed(100)
cols = ['avg_dist','avg_rating_by_driver','avg_rating_of_driver',
        'avg_surge','surge_pct','trips_in_first_30_days','weekday_pct']
df = pd.DataFrame(np.random.rand(10, 7), columns=cols)
df.boxplot(column=cols, rot=90)
