【问题描述】:
尝试从 Excel 工作表中提取数据,应用等式(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:
“社交吸烟者”不应该显示为 0 吗?另外,“从住所到工作的距离”右侧的那个额外的栏是什么?这合适吗?谢谢!
