Tooltip trigger: 'item' with Showsymbol:false

[chanpuraraj]

What problem does this feature solve?

Is it possible to configure tooltip:{ trigger:'item'} with showSymbol: false? Because I'm working with a stacked line graph where I want a tooltip for each area without clicking on the symbol.

Any lead would be appreciated

What does the proposed API look like?

By doing this, one can see the tooltip in stacked line just by hovering on area

I'm also seeing this when plotting 50+ series, which requires hiding the symbol using symbol: 'none' or showAllSymbol: false. In this case, I'd like to still be able to use trigger: 'item' tooltips since there are so many lines. Thanks for your help, maybe there is a workaround I'm not considering?

Also, seems related to issue 12751

any update on this? Is there a workaround to use tooltips trigged with 'item' while hiding symbols?

There is any update? I want to show tooltip for each series separately without showing the symbol, Example: https://codesandbox.io/p/sandbox/stacked-line-chart-forked-y7zn6h

I found another way, try this:

trigger: 'item', axisPointer: { type: 'cross', }, },

Hey, I tried that, but when I hover over a line, it's show points on all the lines , I want to show the point only on the hovered line.

Yep, you have pass your data to "data" field and render with formatter d in series

I found a solution how to show the symbol only when hovering specific line: I change the opacity to 0, and we change the opacity to 1 inside the emphasis object. example: https://codesandbox.io/p/sandbox/stacked-line-chart-forked-dm8kn8
