boxplot points hover events

[joshua-gould]

It would be nice if hover events were fired for points rendered when drawing a boxplot

Could you share an example of your code (codepen/jsbin/jsfiddle) where this isn't working for you? A graph div with a box plot will emit a plotly_hover event that you can bind a function to like so:

var graphDiv = document.getElementById('graph-div');

graphDiv.on('plotly_hover', function(data){
  // do something with the emitted data here
});

When you hover any of the data points (not the box and whisker itself), I would like to show a tooltip corresponding to the text array.

@etpinard perhaps can chime in with more details on this.

@joshua-gould that'd be a nice feature. Thanks for the suggestion!

I suspect making this happen will be tricky. But it could be a good opportunity to split up graph_interact.js

[joshua-gould]

One workaround is to create an additional scatter trace.

Recently I was seeking for the exact same feature.

If it were possible to have it the close future that would be very nice.

+1 for separate hover tool tips for the data points, my users would like to be able to hover the points for labels associated with the numerical data being plotted

I'd love this feature.

Select/lasso dragmodes are coming to box traces soon; it might be good to tackle this ticket too.

To get this done, I'm thinking about adding a hoveron attribute to box trace (similar to scatter and scatterternary):

// (default) this would correspond to the current behavior
hoveron: 'boxes' 

// display hover labels for the visible boxpoints only
// this would support multiple labels per box and per traces 
// for hovermode 'x' and 'y'
hoveron: 'points' 

// both modes at the same time,
// where 'boxes' would take precedence when cursor is over a box
hoveron: 'points+boxes'

any thoughts on this @alexcjohnson @cldougl @chriddyp ?

[chriddyp]

👍 love this! points+boxes will be great, hoveron seems right to me.
I suppose that hovermode options could apply here as well (think horizontally stacked box plots with points)

[alexcjohnson]

Sounds great! hoveron and its values sound perfect. Only question is about:

'boxes' would take precedence when cursor is over a box

I'd probably have gone the other way, since the box is large and has a permissive hover region, give the points small hover regions (reuse the way scatter does it) but let them take precedence within that region.

I have difficulties producing the implemented hover effect:

What did I miss? I used the latest 1.32.1 version...

@dejanskledar #2094 hasn't been released yet.

See changelog here: https://github.com/plotly/plotly.js/releases

[dejanskledar]

Oh, I misunderstood the 62 commits to master thinking that these commits are already included. Thanks.

[dejanskledar]

@etpinard Is there any other way to get the latest lib with #2094 included before the official release?

Thanks.
