Python 改变我的绘图数据点? [直方图]

Python altering my plot data points? [histogram]

尝试从 excel sheet 中提取数据,应用方程(在本例中为 median()),并根据该数据创建直方图。

这是我的代码:

import pandas as pd
import matplotlib.pyplot as plt

pd.set_option('display.max_columns', 100000)
absent = pd.read_excel('Absenteeism_at_work.xls')
col = ['Distance from Residence to Work', 'Transportation expense', 'Month of absence', 'Social smoker',
       'Social drinker', 'Education']

# print(absent.loc[:741, col])

plt.title('The Mean')
plt.xlabel('Attribute of Absence')
plt.ylabel('Value')
# x = ['Distance', 'Trans Exp.', 'Month', 'Smoker', 'Drinker', 'Edu.']
x = absent.loc[:741, col].median()
x.plot(kind="bar", figsize=(5, 5))
print(x)
plt.hist(x)

# print(hist)
plt.show() # shows histogram in side-window

这是终端输出:

Distance from Residence to Work     26.0
Transportation expense             225.0
Month of absence                     6.0
Social smoker                        0.0
Social drinker                       1.0
Education                            1.0
dtype: float64

最重要的是,直方图不正确:

'Social Smoker' 不应该显示为 0 吗?另外,'Distance from Residence to Work' 右边那个多出的横条是什么?这样合适吗?谢谢!

你的图表 x.plot(kind="bar", figsize=(5, 5))plt.hist(x) 正在合并。

x.plot(kind="bar", figsize=(5, 5)):

plt.hist(x):
