Seaborn FacetGrid x刻度标签

Question

我有一个数据框（df），如下所示：

df

        Year           Capacity           Qty
0       2010        4,999 and under         2
1       2010        5,000-6,000             1
2       2010        6,100-7,000             3 
3       2011        4,999 and under         5
4       2011        5,000-6,000             3
5       2011        6,100-7,000             3 
....
94      2019        4,999 and under         1
95      2019        5,000-6,000             3
96      201         6,100-7,000             4 

我想在网格中生成子图，每年一次。每个图都有x轴=“容量”，y轴=“数量”。

    g = sns.FacetGrid(df, col="Year", col_wrap=3, height=4, aspect=1)
    g.map(sns.barplot, "BTU_Rating", "qty")

如何添加“容量”列中列出的x刻度标签？

感谢您的帮助

• 指定g.set_xticklabels(rotation=x)

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

g = sns.FacetGrid(df, col="Year", col_wrap=3, height=4, aspect=1)

order = ['4,999 and under', '5,000-6,000', '6,100-7,000']
g.map(sns.barplot, "Capacity", "Qty", order=order)

g.set_xticklabels(rotation=90)
plt.show()
