[via GitHub]

han-ysys opened a new issue, #18257:
URL: https://github.com/apache/echarts/issues/18257

   ### Version
   
   5.3.2
   
   ### Link to Minimal Reproduction
   
   https://jsfiddle.net/6ta3qk4d/9/
   
   ### Steps to Reproduce
   
   
参照[这个例子](https://echarts.apache.org/examples/zh/editor.html?c=custom-bar-trend)画了一个带有error
 bar的柱状图
   
   ### Current Behavior
   
   根据同一坐标上bar数量的不同，offsetCenter会有不同程度的偏移
   <img width="360" alt="截屏2023-02-10 16 36 26"

   示例中图形同样存在偏移
   <img width="326" alt="截屏2023-02-10 16 36 51" 
src="https://user-images.githubusercontent.com/70315648/218043257-e12d8306-a29e-4713-9a8b-78eb729d0674.png";>
   
   
   ### Expected Behavior
   
   文档里对barLayout的返回值描述：
   ```
   @return {Array.<Object>} [{
           width: number bar 的宽度。
           offset: number bar 的偏移量，以bar最左为基准。
           offsetCenter: number bar 的偏移量，以bar中心为基准。
       }, ...]
   ```
   如上的结果应该是不符合预期的
   
   ### Environment
   
   ```markdown
   OS: macOS Monterey
   Browser: Chrome 96.0.4664.55
   Framework Vue@3
   ```
