使用条形图和框图更改seaborn FacetGrid上的图例标签？

import seaborn as sns
import matplotlib.pyplot as plt

data = sns.load_dataset('tips')

g = sns.FacetGrid(data, col='time', row='sex')

g.map(sns.barplot, 'day', 'total_bill')

legend = g._legend

labels = [text.get_text() for text in legend.get_texts()]

label_mapping = {'Lunch': '午餐', 'Dinner': '晚餐', 'Female': '女性', 'Male': '男性'}

new_labels = [label_mapping[label] if label in label_mapping else label for label in labels]

for text, label in zip(legend.get_texts(), new_labels):
    text.set_text(label)

plt.show()
