绘制饼图和 pandas 数据框表 [英] Plot pie chart and table of pandas dataframe

问题描述

我必须使用matplotlib并排绘制饼图和表格.

I have to plot pie-chart and a table side by side using matplotlib.

要绘制饼图，请使用以下代码:

For drawing the pie-chart, I use the below code:

import matplotlib.pyplot as plt
df1.EventLogs.value_counts(sort=False).plot.pie()
plt.show()

要绘制表格，我使用以下代码:

For drawing a table, I use the below code:

%%chart table --fields MachineName --data df_result2

df_result2是一个包含MachineName列表的表.

df_result2 is a table with the list of MachineName's in it.

不确定是否可以同时放置饼图和表格.任何帮助将不胜感激.

Not sure whether we can place both pie chart and table side by side. Any help would be appreciated.

推荐答案

查看代码:

import pandas as pd
import matplotlib.pyplot as plt
from pandas.tools.plotting import table

# sample data
raw_data = {'officer_name': ['Jason', 'Molly', 'Tina', 'Jake', 'Amy'],
        'jan_arrests': [4, 24, 31, 2, 3],
        'feb_arrests': [25, 94, 57, 62, 70],
        'march_arrests': [5, 43, 23, 23, 51]}
df = pd.DataFrame(raw_data, columns = ['officer_name', 'jan_arrests', 'feb_arrests', 'march_arrests'])
df['total_arrests'] = df['jan_arrests'] + df['feb_arrests'] + df['march_arrests']

plt.figure(figsize=(16,8))
# plot chart
ax1 = plt.subplot(121, aspect='equal')
df.plot(kind='pie', y = 'total_arrests', ax=ax1, autopct='%1.1f%%', 
 startangle=90, shadow=False, labels=df['officer_name'], legend = False, fontsize=14)

# plot table
ax2 = plt.subplot(122)
plt.axis('off')
tbl = table(ax2, df, loc='center')
tbl.auto_set_font_size(False)
tbl.set_fontsize(14)
plt.show()
