This is a feature request.

Please see default "Grouped Legend" example: https://codepen.io/plotly/pen/qjmNXa

Current behavior

It is possible to toggle single traces by clicking on them in the legend. If traces are grouped using legendgroup (like in the example above) not the single traces but the whole group is toggled.

Future behavior

It should be possible to disable the toggling of the whole group and instead toggle the single traces like in no-grouped legends. This would make it possible in the example above to only disable the "points" and only show the "avarage line" of this group.

This should be done by a new option in the legend-settings.
