在一个图中组合框线图

Question

我有一个包含Q和S两列的数据集。下面显示了它的一个示例：

基于“ S”列中的值，我定义了三组：

df = pd.DataFrame(np.array([[1,40], [2, 51], [3, 59], [4, 10], 
[5, 30], [7, 20], [9, 21], [13, 30], [15, 70], [2, 81], [3, 85], 
[4, 67], [9, 120], [2, 481], [12, 51], [16, 120], [8, 9], [14, 15], 
[11, 7], [12, 110], [6, 4], [9, 220], [1, 40], [2, 15], [14, 82], [7, 50]]),columns=['Q', 'S'])

此外，我还为“ Q”列定义了三个组：

Group_1A = df[(df['S'] >= 0) & (df['S'] <= 3)]
Group_2A = df[(df['S'] >= 4) & (df['S'] <= 8)]
Group_3A = df[(df['S'] >= 9) & (df['S'] <= 16)]

我需要弄清楚每组中S的分布，并且需要绘制一个包括所有9个箱形图的图。

最终图应如下图所示：

我可以绘制每个箱形图，但是我不知道如何在一个图中显示所有箱形图。 例如，我可以使用以下代码绘制Group_1A和Group_1B的箱线图：

Group_1B = df[(df['Q'] >= 0) & (df['Q'] <= 10)]
Group_2B = df[(df['Q'] >= 11) & (df['Q'] <= 50)]
Group_3B = df[(df['Q'] >= 51) & (df['Q'] <= 481)]

但是，这只给了我9个箱型图中的1个。

我想知道是否有人可以帮助我。

预先感谢

我刚刚发现我需要使用matplolib.subplots。
