如何在regplot中将图例艺术家从点改为线？

import seaborn as sns
import matplotlib.pyplot as plt
from matplotlib.lines import Line2D

# 创建样本数据
x = [1, 2, 3, 4, 5]
y = [2, 4, 6, 8, 10]

# 绘制回归分析图
sns.regplot(x, y, ci=None, scatter_kws={"color": "blue", "s": 40}, line_kws={"color": "red"})

# 创建自定义图例
legend_artist = Line2D([0], [0], color='red', linestyle='-')
labels = ['Regression Line']

# 关闭默认图例
plt.legend([],[], frameon=False)

# 添加自定义图例
plt.legend([legend_artist], labels)

plt.show()
