如何在seaborn中有一个带有深色网格背景的透明图形？

import seaborn as sns
import matplotlib.pyplot as plt

sns.set(style="darkgrid")

fig, ax = plt.subplots(figsize=(8, 6))
ax.patch.set_alpha(0)  # 设置图形背景透明度为0

sns.barplot(x=[1, 2, 3, 4], y=[10, 20, 15, 25], ax=ax)

import seaborn as sns
import matplotlib.pyplot as plt

sns.set(style="darkgrid")

fig, ax = plt.subplots(figsize=(8, 6))
ax.patch.set_alpha(0)

sns.barplot(x=[1, 2, 3, 4], y=[10, 20, 15, 25], ax=ax)

plt.show()
