[GitHub] [echarts] WangDeTao opened a new issue, #18802: [Bug] 散点地图使用setOption更改zoom时，原先使用appendData追加的点会从头重绘，有其他方法可以达到鼠标滚轮一样的效果吗

WangDeTao opened a new issue, #18802:
URL: https://github.com/apache/echarts/issues/18802

   ### Version
   
   5.3.2
   
   ### Link to Minimal Reproduction
   
   无
   
   ### Steps to Reproduce
   
   1、定时器不断的appendData追加散点数据
   2、同时使用setOption不断的更改geo.zoom的大小，类似鼠标滚轮滚动
   3、此时被追加的点会从头开始绘制，若使用鼠标滚轮则不会绘制，只会更改缩放比例
   
   ### Current Behavior
   
   无
   
   ### Expected Behavior
   
   希望获得相关的方法改变zoom大小，预期达到滚轮一样的效果
   
   ### Environment
   
   ```markdown

   **TITLE**
   
   [Bug] When the scatter map uses setOption to change the zoom, the points originally appended using appendData will be redrawn from the beginning. Is there any other way to achieve the same effect as the mouse wheel?
   
   **BODY**
   
   ### Version
   
   5.3.2
   
   ### Link to Minimal Reproduction
   
   not
   
   ### Steps to Reproduce
   
   1. The timer continuously appendData adds scatter data
   2. At the same time, use setOption to constantly change the size of geo.zoom, similar to mouse wheel scrolling
   3. At this time, the appended point will be drawn from the beginning, if you use the mouse wheel, it will not be drawn, only the zoom factor will be changed
   
   ### Current Behavior
   
   not
   
   ### Expected Behavior
   
   I hope to obtain a related method to change the zoom size, and expect to achieve the same effect as the scroll wheel
   
   ### Environment
   
   ```markdown
   - OS:
   - Browser:
   - Framework:
   ```
