[GitHub] [echarts] MrSulm opened a new issue, #18816: [Bug] 两张相似的echart表connect相连，且每个echart都设置了toolbox.feature.magicType.type为['line', 'bar']，切换其中一个echart后，另一个echart的数据渲染错误。
MrSulm opened a new issue, #18816:
URL: https://github.com/apache/echarts/issues/18816
### Version
5.2.4
### Link to Minimal Reproduction
http://1.andrewblack.sinaapp.com/chart/index.html
### Steps to Reproduce
1、创建两个echart图表，且设置两张图表的toolbox.feature.magicType.type为['line', 'bar']
2、令两个echart图表connect相连，echarts.connect([echart1, echart2])
3、切换其中一个echart的渲染模式，另一个echart的数据就会合并所有相连的echart的数据
### Current Behavior
connect的echart图表渲染了所有echart的数据
### Expected Behavior
仅渲染自己的数据
### Environment
```markdown

- Browser:
- Framework:
```

`echarts.connect` broadcast chart's action in other charts, and make some action (like tooltip) behavior synced.

But for the `magicType` action(this action makes `bar` to `line`, or reverse), this action creates a new series option based on current series data and put them in action payload.

So for these charts which connected, they just get a new series option, but they do not have that series in payload before, so they render the new series data in these connected charts.

@Ovilia Hi, maybe the logic for generating a new series in `magicType` needs to be moved to the front of `mergeOptions`, rather than in `onClick`?
This way, when the action is triggered by another connected chart, the corresponding synchronized action can happen without errors.
