Onclick event in legend to increase thickness of series

Hi, does anyone know if it’s possible to override the behavior when you click a legend item? Something like the following but instead of showing only that one series, we can do something like increase the width of that series.

i dont believe so. so by widen do you mean the days on x?

I meant to use an override to increase the line thickness of the series
