popUp Label needs to allow content.

[MBeatyLTT]

When clicking on a bar element, I need the ability to have my own composable display, like a tooltip. A very dated looking X: Y: readout is not something that works in a good design.

Can you at least make the composables editable? I can do it myself but this library is very.... locked down.

I cant imagine very many use cases where "x:x, y:y" is a visually appealing readout.

Also, having the bar color be filled when clicked does not seem to work, yet there is a constructor that seems to allow it. Is this only partially implemented?
