Seems to be a bug.

[stouch]

you confirm it's a bug ?
thx.

[Ovilia]

Yes. This either should be a bug or a new feature.

[stouch]

? :(

Any update on this? I am running into the same issue.

[echarts-bot]

This issue is labeled with priority: high, which means it's a frequently asked problem and we will fix it ASAP.

As a workaround, you could set an empty tooltip attribute like: ' tooltip:{} ' in the option. Please let me know if it could provide the same result as you expected.

Thanks for the response. Placing an empty tooltip in option does not solve the problem. Nothing is triggered when hovering over the axis.

But hovering over the edge or cross point for one type of data, you will see things like

Hovering over a data point works, however, hovering over just the access does not. When hoving over the axis the user should see all the values associated with the axis not all the data associated with one data series as shown in your diagram.

Thank you, got your point.

As I figured out the main cause of this issue is that radar component hasn't implemented axisPointer yet, so it does not support showing axis message for series.
I've searched for reason from official docs, and got some clues, as follow:

axisPointer is a tool for displaying reference line and axis value under mouse pointer.

Summary: axisPointer is the tool matters most in this issue.

Radar: 1. Coordinate for radar charts. This component is equal to the polar component in ECharts 2. Because the polar component in the echarts 3 is reconstructed to be the standard polar coordinate component, this component is renamed to be radar to avoid confusion.

Summary: radar coordinate is different from polar coordinate in Echarts 3

Radar chart coordinate is different from polar coordinate, in that every axis indicator of the radar chart coordinate is an individual dimension.

Summary: radar coordinate is very special.

How to display axisPointer:
In cartesian (grid) and polar](~polar) and (single axis, each axis has its own axisPointer.

Summary: As a special coordinator, radar does not exist in axisPointer's implements list.

This seems to be a new feature waiting for implement.

Thanks for the information. So it sounds like it is not a bug, it is just not implemented yet. Can we get it implemented? Thanks, Stephen

Hi
I am looking for the same solution. Is there any progress on this ?

[LiZhaji]

Waiting for a result...

[wayward-man]

Waiting for a result...

No result any more

[plixplox]

Is there any progress?

[sandeep-kr-kgp]

Any progress?

[kylewuyinhai]

🙂,any progress?

[Ovilia]

This problem is tricky because it's actually not an axis but an indicator. So if anyone is interested in making a PR, a new value of trigger: 'indicator' shoud be provided.

[PIMBA]

:), any progress or workaround ?

May I know if there is any progress on this issue/feature?

Any news on this and the solution proposed by helgasoft?
