sns.countplot(x='smoking_history', data=df) plt.title('Smoking History Distribution') plt.show()照上

要在条形图上显示每个条形的具体数值，可以添加以下代码：

import seaborn as sns
import matplotlib.pyplot as plt
import pandas as pd

df = pd.read_csv('data.csv')
sns.countplot(x='smoking_history', data=df)

# 添加具体数值
for i in range(len(df['smoking_history'].value_counts().index)):
    plt.text(i, 
             df['smoking_history'].value_counts()[i], 
             df['smoking_history'].value_counts()[i], 
             ha='center', 
             va='bottom')

plt.title('Smoking History Distribution')
plt.show()

这样就会在条形图上显示每个条形的具体数值。
