[GitHub] [echarts] Raphyyy opened a new issue, #17357: [Feature] Disable emphasis state but enable on legend hover
Raphyyy opened a new issue, #17357:
URL: https://github.com/apache/echarts/issues/17357
### What problem does this feature solve?
The option `series-line.emphasis.disabled` has been added to solve this issue I opened : https://github.com/apache/echarts/issues/14952
I am still using the zIndex trick (https://jsfiddle.net/45scamx3/) to disable emphasis state on series hover because I want to enable emphasis when the user is hovering the legends.
However, this workaround is throwing z-level warn and is causing other issue relative to series zIndex.
I also have to catch the event `highlight` to enable or disable emphasis state depending on the event has been triggered either by chart hovering or legend hovering.
I am looking for an option to disable emphasis state on chart hovering but enable it on legend hovering.
### What does the proposed API look like?
An option `series-line.emphasis.triggerOn` which could have the value `all`, `legend` or `series`.

Hi. Can you further explain why you wish to disable emphasis state but enable it on legend hovering?

Hi,
I have multiple sensors emitting data on different timestamp. So the emphasis state when you are hovering the series produce a undesired flicking effect, see https://github.com/apache/echarts/issues/14952#issuecomment-842117188
However, be able to highlight only the serie when its legend is hovered by the user is a must feature for me, as my users have multiple sensors and they are actively using this to focus on one sensor's data.

Edit: Also, the emphasis state set with series-line.emphasis.focus = "series" (to allow the legend hovering) is simply unsuitable for line series charts with multiples series emiting with data at the same time. If you have tooltip set with tooltip.trigger = "axis" like I do, you don't want your series to be highlighted when you are hovering the chart.

you can see proper hovering effect in another charts library amcharts5. in [that example](https://jsfiddle.net/api/post/library/pure/) i feel much more comfortable data investigating process with my mouse.
