[Feature Request] Disable click/hover events per line/data

[dummdidumm]

Feature Request

It would be great if there was a functionality to disable hover and/or click events per line/data. Something like this:

Plotly.newPlot(
  "myDiv",
  [{
     x: [1, 2, 3, 4],
     y: [16, 15, 11, 9],
     type: "scatter",
     // If I hover over a data point, there will be no plolty_hover/unhover event for this line.
     // There will be no hoverlabel, too.
     // Default is true
     hoverevents: false,
     // If I click on a data point, there will be no plolty_click event for this line.
     // Default is true
     clickevents: false
  }]
);

hoverinfo: 'none' or hoverinfo: 'skip' should do the trick.

Thanks for the info on hoverinfo: 'skip', I did not know about that. hoverinfo: 'none' is not enough because when I hover a datapoint from a line with hoverinfo: 'none' which superimposes a datapoint from another line, the hoverinfo: 'none'-line will still get priority when hovermode: 'closest' is active.

But there still is no way to distinguish between hover and click events, so you cannot deactivate one thing when you don't want to deactivate the other.

Maybe there could be a new field clickinfo which has the same options as hoverinfo. When clickinfo is not set, it will use the options of hoverinfo, but you can override them to have specific behavior for click events.

Fair point. I'm curious though @dummdidumm how are you handling your click events? There should be a way to tell which points to "skip" in the handler.

[dummdidumm]

The same things that I wrote above about the hover-event are also true for the click event. So if I hover over/click on a datapoint which is exactly on top of another datapoint, inside points of the event handler I only get the datapoint which is on top.

So if I would like click events to happen on the datapoint but not hover events, I cannot achieve this currently.

The "only the top-most point is passed to points, I want all points in that area" is a topic/feature request on its own I think.

That's tracked in: #720

Hi - we are currently trying to tidy up Plotly's public repositories to help us focus our efforts on things that will help users most. Since this issue has been sitting for several years, I'm going to close it. If it's still a concern, we'd be grateful if you could open a new issue (with a short reproducible example if appropriate) so that we can add it to our backlog. Thanks for your help - @gvwilson
