Steps to Reproduce

Current Behavior

When using red writing (string), you can change the color of nodes and polylines at the same time.
When using blue writing (callback function), only the node color is changed, and the polyline color remains unchanged.

The results of the two configurations are inconsistent

Expected Behavior

When the color of itemStyle uses the callback function, the line color can also change.

Environment

- OS: macOS

- Framework:

This problem should have been fixed before, but it has appeared again now. Please take a look. Or it needs to be used with other configurations, please let me know. I didn't find it in the documentation, thank you

confirmed, wow this one has been around for a lo-o-ng time 😲

ohhhh, thanks for answer! is there any plan to fix this issus?

If an issue does not get into milestones or Backlog in a week or two, roll up your sleeves and DIY. ECharts PRs are not easy though, see >130 pending...

What confuses me is that the two configuration methods of a same attribute have two different results. And what can I do？use function way with any other configurations or somethings？
