Labels / DataLabels supporting word-wrap and/or clipping

[Offbeatmammal]

at the moment I’m using some janky code to clip a label if it’s too large to fit into a treemap box.

curious if it’s possible using existing capabilities to do something like automatic wordwrap to try and fit the label into the box, and if it can’t fit then truncate (with ellipsis… to indicate truncation)

as an added complication, the text I’m using in the labels already has the format:
potentially long block of text that would need word-wrap or trunction some mandatory text that should always show

happy to pass the wrappable text and the mandatory line as two array elements

worst case I can re-visit my truncation code and see if I can work something out (but hoping someone smarter than me has already solved the problem!)

I'd really like this as well. As far as I can tell, you cannot write multiple lines right now?
