wadrn opened a new issue #14680: URL: https://github.com/apache/echarts/issues/14680
### Version 5.0.2 ### Steps to reproduce I have used echarts by 'echarts-for-react'(https://github.com/hustcc/echarts-for-react) in my code, and react hooks to update states. When the data changed, it will auto changed the option ,and I have set param `notMerge` = true for not merging old lines when data updated. But when I changed the data, it still kept both lines including older & newer in one chart. ### What is expected? Update chart with new line not merging with old one when i set notMerge = true ### What is actually happening? it will show both lines using merging mode <!-- This issue is generated by echarts-issue-helper.
