Possible to have nested (or hierarchical) legends?

This is what I would think “legend groups” are for, but by the examples, does not seem to do what I want. I would like to be able to have something like this for plots that say have 4 traces, with two in one category and two in another. The categories would be the same color.

Hi there,
Nested legends aren’t possible at the moment.
Legend groups currently available in Plotly are for grouping traces so you can toggle groups of traces on/off at once (https://plot.ly/python/reference/#scatter-legendgroup).

Thanks Chelsea! I was trying to understand the value of legend groups–at first glance seemed to be just another way to set line style. But the toggle thing is really nice.

@maxpuff it is under Grouped Legend here https://plot.ly/python/legend/

Any news on this ?

Any news on this 2024? I am looking for assigning one subplot to multiple legend groups for multiple filtering.

Check the curveNumber value passed in the plotly_legendclick event to know whether to hide the group or just the trace
