[Feature] How to get a BMap instance in EChart
**BODY**
### What problem does this feature solve?
I want to select any point on the map in EChart (not the location that
EChart has drawn on the map, but just click on a certain place on the map), and
the left side of the clicked point can be obtained. What should I do? ? ?
Vue version: ^3.2.33
Map: Baidu map
EChart version: ^5.4.1
Methods that have been tried so far:
1 through the following code
```
echarts.registerTheme('theme', EChartsTheme.theme);
const myChart = echarts.init(document.getElementById('projectMap')!,
'theme');
//Try to get the map instance
const map = myChart.getModel().getComponent('bmap').getBMap();
```
I refer to the official extension of Baidu map in EChart, but
`myChart.getModel().getComponent('bmap').getBMap()` this code reports an error.
The specific error is `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');
//An error is reported here, addEventListener does not exist
bmap. addEventListener('click', function (e) {
alert('click!');
});
```
3 Try to find the relevant map instance by printing the current window
object.
None of the above methods were successful.
I currently have two ideas:
1 Get the instance of the map in EChart, and then you can operate it
casually.
2 Through the things in EChart, directly control the click.
### What does the proposed API look like?
Get the BMap object directly
