I have created a double layered donut chart, but when I've added the labels, not all of the labels are showing up? This seems to be happening for the smallest slices of the donut chart layer.
Upfront! Just a check! Are you aware of "Allow labels to overlap other marks" functionality?
Try click Label on the Marks Card and selecting "Allow labels to overlap other marks" under Options.
Or right click on the slices in the donut chart layer that don't have labels and select Mark Label > Always Show.
