Helper IIIHow to customize data label in a Donut chart
Hello EstherBR ,
what rohit1991 mentioned is not possible since the details field doesn't accept measures as you can see below, what I would suggest is to add the profit value as a tooltip and when they hover they can see it.
of use field parameters so that they can switch in the donut chart between sales and profit .
or use another visual that accepts a measure in the data labels like bar chart and then you can add the concatinated measure that he added in the data labels value.

Super UserHi EstherBR
Unfortunately, donut chart labels cannot be customized in Power BI.
Unlike bar/column charts (where you can build a concatenated label using DAX), donut/pie visuals only allow the built-in label options. Any additional information—like Profit—can appear only in the tooltip, not on the label itself.
From a data visualization and UX perspective, this is actually a limitation of the visual itself:
Donut charts are visually appealing but not effective for precise comparisons.
Our eyes struggle to compare curved arc lengths, so it’s hard to judge which segment is bigger—there are even museum illusions demonstrating this.
If you're trying to compare “part to whole” for a single category, a simple pie chart is clearer.
If you need to compare multiple categories, a bar chart is always more readable and accurate. Even when the values are percentages, a bar chart makes the differences obvious because we compare lengths, not curves.
If your goal is to emphasize one segment out of the whole, you can achieve it visually with a highlight/frame technique, similar to the image you showed—simply horizontal instead of vertical.
