如何通过Seaborn和Matplotlib在Python中让x轴标题出现在relplot的所有子图中？

import seaborn as sns
import matplotlib.pyplot as plt

data = sns.load_dataset('tips')

g = sns.relplot(data=data, x='total_bill', y='tip', col='time', hue='smoker', kind='scatter')

for ax in g.axes.flat:

    ax.set_xlabel('Total Bill')

import seaborn as sns
import matplotlib.pyplot as plt

data = sns.load_dataset('tips')

g = sns.relplot(data=data, x='total_bill', y='tip', col='time', hue='smoker', kind='scatter')

for ax in g.axes.flat:
    ax.set_xlabel('Total Bill')

plt.show()
