> 应该是因为 geo 和 map 设定了 top 以及 zoom 的原因，当前的配置项 effectScatter 无法跟随地图同时缩放。
> 在当前的例子基础上稍微改了下，可作为参考。https://www.makeapie.com/editor.html?c=xmveYphRJD=2
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)
```

> 可以提供个示例代码，方便我们定位问题。
### 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

转换过了 没有效果， 地图的点往上偏移了点
