### What problem does this feature solve?
我想要在EChart中实现地图任意选点(不是EChart已经在地图上绘制好的地点，而是随便点击地图某一处)，能获取到点击处的左边。该怎么办？？？
vue版本:^3.2.33
地图:百度地图
EChart版本:^5.4.1
目前已经尝试的办法：
1 通过下边这段代码
```
echarts.registerTheme('theme', EChartsTheme.theme);
const myChart = echarts.init(document.getElementById('projectMap')!,
'theme');
//尝试获取地图实例
const map = myChart.getModel().getComponent('bmap').getBMap();
```
我参考了EChart中百度地图的官方扩展，但是`myChart.getModel().getComponent('bmap').getBMap()`
这段代码报错了。具体的错误是 `Uncaught (in promise) TypeError: Cannot read properties of
undefined (reading 'getComponent')`
2
```
echarts.registerTheme('theme', EChartsTheme.theme);
const myChart = echarts.init(document.getElementById('projectMap')!,
'theme');
const bmap = echarts.getMap('bmap');
//这里报错了，addEventListener 不存在
bmap.addEventListener('click', function (e) {
alert('click!');
});
```
3 通过打印当前的window对象，尝试寻找相关的地图实例。
以上办法都没有成功。
我目前的思路有两个：
1 获取到EChart中地图的实例，然后就可以随便操作了。
2 通过EChart中的事情，直接控制点击。
### What does the proposed API look like?
直接获取到BMap对象
