# Mac只能用Python了
import pandas as pd
import matplotlib.pyplot as plt

# 读入清洗好的数据
df = pd.read_csv('./titanic_train.csv')

# 数据透视表用到的数据 df_temp
df_temp = df[['Embarked', 'Survived']]

# 生成数据透视表
## 方法1
table = pd.pivot_table(df_temp, index=['Embarked'], columns=['Survived'], aggfunc=len)
table = pd.pivot_table(df_temp, index=['Embarked'], columns=['Survived'], aggfunc=len)
## 方法2 数据交叉表
table = pd.crosstab(df.Embarked, df.Survived)

# 画图
table.plot(kind='bar')
plt.show()
