How to merge/collapse legend lines that are in the same legend group

[AIMPED]

Hey @PainOchoco welcome to the forums.

We had a similar question a while ago:

Multiple vlines as one legend element

Good afternoon! I’m struggling to create multiple year vlines in my chart. This command does work well: fig.add_vline(name="Yearlines", x="2023-01-01", showlegend=True, dash="dot")) But if I’m trying to add multiple years, like this: fig.add_vline(name="Yearlines", x=["2022-01-01", "2023-01-01"], showlegend=True, dash="dot")) it does not crash, but it does not show any vline at all… Am I’m missing something? Thank you for your help!
