Legend grouping in pie chart?

Is it possible to group legend entries in pie charts?

I am working on two nested pie charts where the outer chart breaks down the categories of the inner chart into more detail. Thus, I would like one legend entry to turn on/off one region on the inner chart and a number of corresponding regions on the outer chart. Is there any way to do this?

Hi @agplot,

I don’t think this is possible at the moment, but you could raise an issue with the plotly.js project if you’re interested (https://github.com/plotly/plotly.js).
