Yes, that is the right part to get started with. You could just copy the whole \startuseMPgraphic and rename it for editing (to let’s say rules:under:bardots), then do

  \definebar[underbardot]    [undergraphic][mp=rules:under:bardots]

and play with the mp until you are happy with the output.

But the problem is that you have to create an “underbardot" that contains both the bar and the dots, to fix the non-nesting problem. It is then quite hard to get that definition to align properly with any enclosing “underbar” (I tried something like that a while ago and basically gave up. I did not want to spend a whole of time on it so I just told the client “computer says no").


> Another question: what do you mean with a dy-shift version?

Nested bars have a parameter ‘dy’ which controls the vertical shifts needed to make sure that they do not overlap. Text backgrounds do not have that option at all.
