We need to be able to label specific data points with dynamically generated values (including text). Use cases include:
* Labeling the first or last point of line charts with values
* Labeling the last point of series in a line chart with the series name, to directly inform the user which series is which, rather than have them constantly move their eyes between a legend and the many series on a graph.
* Labeling particular values of interest, to aid storytelling.
These things are bulk-standard features of good dashboard design, and are essential in order to design optimal user-friendly dashboards with low cognitive burden.
Gotta say that humble ol' Excel is streets ahead of Power BI in regards to data labeling.
Note that measure-driven tooltips are NOT a substitute for this feature. We need ways to draw the users' attention to particular points or features without relying on mouse-over.
I'm currently using Cards and Advance Cards (to get conditional formatting, EG. a Branch name goes Red if [condition]) to do this.
This is fairly basic, but so important for making dynamic reports.

Good idea. I‘d like to add Maximum and Minimum to the list of line chart data points that need to be labeled by measure driven labels
