How to get all subgraph data for a specified coordinate

[wanghe199512]

I built multiple subgraphs, using click or hover on one subgraph, and how to use this coordinate to get data from other subgraphs（Click or use hover on a subgraph to get all the data for the other subgraphs at that coordinates）

myplot. On (' plotly' , function (eventdata){
// currently eventdata has only one subgraph data
}

Email from @wanghe199512 :

only one can be obtained now, as shown below:

Hovering over the graph pointed by the arrow returned two pieces of data, and my request was: return the data from the other graphs as well.

In the subgraph mode, I think this is better and more flexible. Echarts can do this

A full solution to this issue would be best done as a hovermode that spans subplots - proposed long ago and lots of 👍 but hasn't bubbled up to the top #2114

Meantime, if your traces all have the same x data it's pretty easy to get all the corresponding y values inside the event handler because they'll be at the same position in the data arrays - look at points[0].pointNumber, then you can do something like:

const yVals = myplot.data.map(trace=> trace.y[eventdata.points[0].pointNumber])
