Hi! We've received your issue and please be patient to get responded. 🎉 The average response time is expected to be within one day for weekdays.

In the meanwhile, please make sure that it contains a minimum reproducible demo and necessary images to illustrate. Otherwise, our committers will ask you to do so.

A minimum reproducible demo should contain as little data and components as possible but can still illustrate your problem. This is the best way for us to reproduce it and solve the problem faster.

You may also check out the API and chart option to get the answer.

If you don't get helped for a long time (over a week) or have an urgent question to ask, you may also send an email to dev@echarts.apache.org. Please attach the issue link if it's a technical question.

If you are interested in the project, you may also subscribe our mailing list.

Have a nice day! 🍵

Maybe we can improve this along with improved colorBy. In #13788 , we supported colorBy for basic series (but not tree, treemaps, sankey, ...). So perhaps it can be improved along with enhanced colorBy in the future.
