如何将seaborn boxplot与其x ticks居中对齐？

import seaborn as sns
import matplotlib.pyplot as plt

data = {'Category': ['A', 'A', 'B', 'B', 'C', 'C'],
        'Value': [1, 2, 3, 4, 5, 6]}
df = pd.DataFrame(data)

sns.boxplot(x='Category', y='Value', data=df)

# 获取当前的坐标轴对象
ax = plt.gca()

# 设置x轴刻度标签的位置为居中对齐
ax.set_xticklabels(ax.get_xticklabels(), ha='center')

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

data = {'Category': ['A', 'A', 'B', 'B', 'C', 'C'],
        'Value': [1, 2, 3, 4, 5, 6]}
df = pd.DataFrame(data)

sns.boxplot(x='Category', y='Value', data=df)

ax = plt.gca()
ax.set_xticklabels(ax.get_xticklabels(), ha='center')

plt.show()
