This was implemented in #36511 and shipped since version 7.3.

@timroes reopening after talking with @sherry-ger
Currently, in visualize, there are labels for each split area in the bar but not for the total and not for Lens.

I don't think we will support any kind of value labeling in Lens until the underlying chart library has support for this. There are several issues, one of them is that the subtotal feature isn't supported, and the other is that the text color needs to be handled better (elastic/elastic-charts#238)

Closing this as duplicate of #69100

@timroes This is not a duplicate, it's asking for a different feature which elastic-charts does not yet support: elastic/elastic-charts#635

@markov00 what do you think about this improvement on top of the recent change in this area #106231

We can definitely work on that, I will open an issue to track this feature request in charts

I think that it would also be very useful to be able to display part value labels in a stacked bar chart. Total value displayed outside the bar and part values inside the parts.
