hoverlabel not working properly with subplots when resizing window

[mbkupfer]

There is something buggy going on with my subplots using x unified

When creating the plot on its own, the hoverlabel is fine, but when I put it inside a dash app via dcc.Graph component, the labels don’t show. I created two versions in chart studio, one that is exported from the dash app and the second created using the chart_studio module.

The latter works fine, but the former works initially, but then all but the last plot’s hover labels no longer work when the window is resized.

Any idea what is going on here?

Created using dash app via dcc.Graph: https://chart-studio.plotly.com/~mbkupfer/72/#/

Created using chart_studio (works good): https://chart-studio.plotly.com/~mbkupfer/70/#plot

Dependencies:

dash                      1.13.3
dash-core-components      1.10.1
dash-html-components      1.0.3
dash-renderer             1.5.0
dash-table                4.8.1
plotly                    4.8.2

[Update]
It actually looks like this issue occurs in both created plots.

@archmoj @antoinerg can you take a look at this plz?

@mbkupfer do you think it is a regression?

Looks like the expected behaviour to me.
Should we remove the bug tag and add a feature request tag?

@archmoj couldn't say, this is my first time using this feature

Looks like the expected behaviour to me.

For the hover data to not show?

FWIW, this issue only comes up when I used shared_xaxes. I have been able to get a workaround by not using shared and making the other axes invisible.

For the hover not to show across subplots.

Am curious to see how the results look like.

Oh, no...what I meant was that it simply didn't show. For example, in first screenshot, I get a unified hoverlabel on the first plot, but when I resize the window it no longer shows...all I get are the spikelines. The only subplot that shows hoverlabels at this point is the last one.

@mbkupfer now could you please modify the issue title to better reflect the problem you observed?
Thanks in advance,

Here is a codepen to help illustrate the problem.
Not only unified hover but also other modes have this problem.

And this is a regression since v1.54.2.
