在seaborn jointplot上添加任意线条

import seaborn as sns
import matplotlib.pyplot as plt

data = sns.load_dataset("tips")  # 示例数据
sns.set(style="ticks")
g = sns.jointplot(x="total_bill", y="tip", data=data)

line_coords = [(10, 2), (40, 5)]  # 线条的起始点和终止点坐标
line = plt.Line2D(line_coords[0], line_coords[1], color='red', linewidth=2)  # 创建线条对象
g.ax_joint.add_line(line)  # 将线条添加到jointplot中
