> 注意坐标系，阿里云这个应该是高德坐标系，在百度地图上显示需要转换下。
```js
//将腾讯/高德地图经纬度转换为百度地图经纬度
qqMapTransBMap(lng, lat) {
let x_pi = 3.14159265358979324 * 3000.0 / 180.0;
let x = lng;
let y = lat;
let z = Math.sqrt(x * x + y * y) + 0.00002 * Math.sin(y * x_pi);
let theta = Math.atan2(y, x) + 0.000003 * Math.cos(x * x_pi);
let lngs = z * Math.cos(theta) + 0.0065;
let lats = z * Math.sin(theta) + 0.006;
return {
lng: lngs,
lat: lats
}
}
```
转换过了 没有效果， 地图的点往上偏移了点

### 代码如下：
> 可能数据点比较大，您只要看points就行了，我这个点应该在浦东新区最下面，而他跑到了最上面，与实际偏差太大

大佬确实强，非常感谢回答我的问题，有空帮我看另外一个问题吗？问题在这里 [issues](https://github.com/apache/echarts/issues/14493)
>还是这个demo,我启动了个定时器，切换了地图数据，从中国-上海-浦东新区，来回切换，我想切换的时候加上切换动画，请问有什么方法可以加吗？
```javascript
setTimeout(_=>{
this.$echarts.registerMap('chinaMap', data)//类似这样切换了数据源
}, 1000)
```
