python sns.countplot() 绘画条形图详情

import pandas as pd
import numpy as np
import seaborn as sns
import matplotlib.pyplot as plt
titanic=pd.read_csv('train.csv')
titanic.columns
#x轴上的条形图
sns.countplot(x='Pclass',data=titanic)
plt.show()

#或者直接使用df[col]
sns.countplot(x=titanic['Pclass'])

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

titanic=pd.read_csv('train.csv')
titanic.columns

#y轴上的条形图
sns.countplot(y='Pclass',data=titanic)
plt.show()

#或者直接使用df[col]
sns.countplot(y=titanic['Pclass'])

# hue
sns.countplot(x='Pclass', hue='Survived', data=titanic)
plt.show()

# 或者直接使用df[col]
sns.countplot(x=titanic['Pclass'], hue=titanic['Survived'])

import pandas as pd
import seaborn as sns

titanic = pd.read_csv('train.csv')
titanic.columns

#order,hue_order
sns.countplot(x='Pclass',hue='Survived',data=titanic,order=[3,2,1],hue_order=[1,0])
plt.show()

import pandas as pd
import seaborn as sns

titanic = pd.read_csv('train.csv')
titanic.columns

#调色板
sns.countplot(x=‘Pclass',data=titanic,palette=“Set3”)
plt.show()

#ax指定子图
fig, ax = plt.subplots(1, 2, figsize=(10, 5))
sns.countplot(x='Pclass', data=titanic, ax=ax[0])
sns.countplot(y='Pclass', data=titanic, ax=ax[1])
plt.show()
