#### 首先，df长这样： ####

#### 一、最简单的箱型图（boxplot） ####

import seaborn as sns
    sns.boxplot(data = df, x = "age")

#### 二、两个变量的箱型图 ####

import seaborn as sns
    sns.boxplot(data=df, x="age", y="class")

#### 三、hue ####

import seaborn as sns
    sns.boxplot(data=df, x="age", y="class", hue="adult_male")

hue：将每个箱型图按照hue再分类

#### 四、dodge ####

import seaborn as sns
    sns.boxplot(data=df, x="fare", y="deck", hue="deck", dodge=False)

dodge：为false的时候，![af259e2108d842abb0bd371643f6ba00.png][]

dodge：为true的时候，![523d0bdacd5f4853a4f186eb2e1b790d.png][]

#### 五、样式 ####

import seaborn as sns
    sns.boxplot(
        data=df, x="age", y="class",
        notch=True,   #notch 凹槽，即中位数处是否有凹槽
        medianprops={"color": "coral"},   #中位数线的颜色
        showcaps=True,     #设置上下限的那个杠
        flierprops={"marker": "x"},   #离群值的符号
        boxprops={"facecolor": (.4, .6, .8, .5)},  #箱子的颜色
    )

#### 六、样式 ####

import seaborn as sns
    import matplotlib.pyplot as plt
    
    fig = plt.figure(1,(10,5),dpi = 250)    
    ax = plt.subplot(111)
    plt.sca(ax)
    
    sns.boxplot(data = taxi_data, x = "hour", y = "duration", ax = ax)  
    #ax是画纸，要指定把boxplot画在plt画的这张ax上（plt.sca(ax)），不然有可能出现plt画一张纸，boxplot画另一张纸
    
    plt.ylim(0,3000)
    plt.show()
