Get center node value of the rendered sunburst chart Plotly.js 2.2.0

[saravanch2018]

I am using plotly.js in my angular 10 app. Sunburst chart feature is working fine. I have a requirement where I need to take the center piece of the data rendered and use it to call a few webservices to populate other sections of the page.

Scenario 1 Works fine: This works when I click from the initial root node and move towards the leaf (outer edges), because the outer edge value can be read using sun burst click event and eventually I know it is going to be the center piece.

Scenario 2 has problem But when I try to click the center piece and move towards its parent (like reverse direction) , this center piece now becomes a leaf(becomes immediate outer edge) and its parent becomes the center piece, I wanted to know the center piece's value and use it to call other web services for my page. But I am unable to read the value of the center piece in this context.

I am curious to know how we can handle scenario 2. If there are properties/events to get hold of the center piece value after the chart is re-rendered, that will be great.

Hi - we are trying to tidy up the stale issues and PRs in Plotly's public repositories so that we can focus on things that are still important to our community. Since this one has been sitting for several years, I'm going to close it; if it is still a concern, please add a comment letting us know what recent version of our software you've checked it with so that I can reopen it and add it to our backlog. Thanks for your help - @gvwilson

Still an issue. Need to know the root node while zooming out.

thanks @saravanch2018 - I'll add it to our backlog, but realistically it will be quite a while before anyone can look at this :-(
