如何在pycharts百度地图的轨迹图中每个点加上坐标值

在做一个轨迹图，想在每个点的上方加上坐标，请问我该如何修改我的代码

import json
from pyecharts.charts import BMap
from pyecharts import options as opts

# 读取项目中的 json 文件
with open(r"C:\Users\HWY\Desktop\智能巡防\busRoutines.json", "r", encoding="utf-8") as f:
    bus_lines = json.load(f)
    print(bus_lines)

c = (
    BMap(init_opts=opts.InitOpts(width="2000px", height="1200px"))

我就看了看看代码，首先得获取这个坐标啊，你这里面没找着，不行就用别的点去计算一个坐标啊，你搜搜相应文档，看看有没有获取坐标的函数啥的
