As shown in the attached picture of Donut charts, dimension values show where proportions seem to be evenly divided, but they don't show where proportions seem to be unevenly divided for the same area. The far right Donut chart was copied to create other Donut charts to the left with same properties with different rating expressions from 1 to 4. Inner radius of Donut was changed to adjust thickness, but it had no effect on showing dimension values of rating at all. If one Donut chart is showing dimension values of the same chart area, can other Donut chart in the same chart area show dimension values consistently? The size is 4 cells across and 3 cells down in Narrow of the sheet property. When the far-left Donut chart was expanded to an area of 7 cells across and 8 cells down, only 2 rating dimension values showed (yellow and red regions).
Another solution could be a property to either show or hide dimension values in the Donut/Pie chart object for consistent look and feel across sheets.
