fangxiezhen opened a new issue, #18855:
URL: https://github.com/apache/echarts/issues/18855
### What problem does this feature solve?
My requirement is to highlight the entire chain when the mouse hovers over
it. So I added a mouse hover event to find the chain when the mouse hovers over
a node, and then used dispatchAction - highlight about some points. However, I
found that although the nodes were highlighted, the links between them were not.
What should I do to achieve my requirement? Here is my code:
` const name = getAllLightName(p.data?.id, currentData.links,
currentData.nodes);
chart.dispatchAction({
type: 'highlight',
seriesIndex: 0,
name,
});`
### What does the proposed API look like?
I need an API to implement this requirement, or is there currently a
suitable way to achieve my requirement? Thank you very much
