Support for multiple lines

[Urriel]

Hi 👋

I am trying to add support for multiple bars in the same row that will overlap in time but be displayed on top of each other.

I don't think I am getting on the right path here. Do you have any idea on how I should implement this ?

The desired behavior ought to be specified a bit more precisely here. So each bar in a row should be rendered in its own "sub-row"?

I want to display these bars on top of each other instead of having them overlapped.
