Python【Matplotlib】鼠标单击事件判断点击的是否为图例

直接上代码：

import matplotlib.pyplot as plt

# 创建一个简单的图表
fig, ax = plt.subplots()
line, = ax.plot([1, 2, 3], label='Line 1')
ax.legend(draggable=True)

# 获取图例对象
legend = ax.get_legend()

# 获取图例的边界框
legend_bbox = legend.get_window_extent()


def call_move(event):
    axtemp = event.inaxes
    mouse_x = event.x
    mouse_y = event.y
    print(f"鼠标_x={
     mouse_x}")
    print(f"鼠标_y={
     mouse_y}")

    if axtemp and axtemp.get_legend():
        legend_bbox = axtemp.get_legend().get_window_extent()
        left_bottom = legend_bbox.get_points()[0]
        right_top = legend_bbox.get_points()[1]

        if left_bottom[0] <= mouse_x <= right_top[0] and left_bottom[1] <= mouse_y <= right_top[1]:
            print("鼠标点击在图例矩形区域内。")
        else:
            print("鼠标点击在图例矩形区域外。")



fig.canvas.mpl_connect('button_press_event', call_move)

plt.show()
