From the image it looks to be PowerBI Visual question, not Excel one.
Unfortunately, there are no straight forward way to have text values in data label for PowerBI standard charts.
There are ways to workaround it, but non are easy to implement and will require some significant effort on your part. 1. R-Script visual or Python visual
You'd use dataframe to construct your visual on the fly using script. This is probably the method I'd use, but will require you to have R/Python environment set up on your machine. Do note that you can't use some popular libraries (R - No tidyverse support etc).
So you must be careful when setting up your environment to ensure compatibility with PowerBI Service. You can find some examples at chandoo.org blogs. https://chandoo.org/wp/visualize-salary-increases-jitter-plot/#comments https://chandoo.org/wp/power-bi-panel-charts/
