"Selected data" with Parallel Coordinates Chart

[EllisShen]

Hi,

I found in another thread, there's an example of using "onRestyle" event to get "constraintrange" data. However, this is not the data of highlighted lines of parcoords chart. is there a simpler way to find "highlighted" line data from the event handler?

Thank you!

Can you provide a bit more info about the context of your question? Which event handler are you referring to and which example are you referring to? :)

@nicolaskruchten my bad, this is the thread that I referred: https://community.plot.ly/t/displey-selected-data-in-parcoords/4055

I want to know what data that user selected with Parallel Coordinates's constraint, or so-called brush feature. Usually, the selection activity should trigger the associated events, such as onSelecting, onSelected...etc, however, the only workable example I can find now is using restyle event callback to catch the constraint range of the data.

Do you know if there's a way to read all selected line (data) back from one of the event callback?

[nicolaskruchten]

You should be able to read the same values out of the data object that gets passed into the onUpdate callback. Does this not work?

@nicolaskruchten Can you elaborate on your onUpdate comment? How does the data object provide the filtered lines? In other words, the rows which meet all the criteria.

I have the same problem and can not solve it. Any ideas?

I would also really appreciate a solution. From a previous post https://github.com/plotly/plotly.js/issues/170 , I see that an elegant solution may be a longer term project. However, adding some clarity around how a python developer could use javascript as a workaround would be extremely helpful!

+1 to this thread - the ability to add constraints to each axis and highlight individual data points satisfying those constraints is a lot more useful if those data points are returned

[phylroy]

+1 to this as well. Is there a clear example how to get the selected values?

Any updates?
