Drawing Detail Line in a Legend

i was wondering if there any way to bake GH curves as detail line into a legend ?

i’hv try using the get “set element curve” but it end with just showing the last set of curve.

If you go through the ui the options are very limited, even more so in the API where you can’t even create a legend. These look more like door schedules, perhaps there’s a better way to accomplish your end goal?
