Compare the composition of several groups using one donut per group, for example the product-category mix of each region. A slice's percentage belongs to its own donut, not to all groups combined.

Build regional product mix

1. In Components → Charts → Proportion, add Grouped donuts and select an Analysis model in Data.
2. Set the following fields using +, then Back:

Slot	Example	Meaning
Grouping (Donuts)	Region	One donut per member. Not drillable.
Details (Slices)	Product Category	Slices repeated within each donut.
Measures	Net Sales	Size of the slices. One measure.
Color	Optional	Custom colour mapping.
Tooltips	Optional quantity or order count	Supporting detail.

3. Restrict Filters to one comparable period, such as Year = 2025.
4. Check that each donut represents the intended group. Swapping the two dimension slots changes the question the chart answers.

Use additive, non-negative measures; a rate is not a meaningful slice weight. Limit the number of groups and categories so each donut stays readable.

A new Grouped donuts component is placed at 480 × 300 px.

Settings that matter

All in the Style tab.

Setting	Effect	Default
Plot area → Center radius	Hole size as a percentage of the donut radius, 0–90%.	66%
Plot area → Spacing	Space between donuts, 0–100 px.	3 px
Plot area → Merge small slices, Merge slices below, Merged slice name, Merged slice color	Combines small slices into one slice at the end of each donut, as on Pie. A member is merged only if it is below the threshold in every donut, so all donuts keep the same slices.	Off; 3%; Others; neutral grey
Grouping labels → Show, Font	Group name in the centre of each donut.	On
Data labels → Show	Slice labels.	Off
Data labels → Label contents	Same options as Pie, from Name to Name & value & percentage.	Value
Data labels → Position	Outer or Inner.	Outer
Data labels → Font, Display units, Decimal places	See Display Units and Decimal Places.	—
Data labels → Min. proportion	Slices below this share, 0–30%, get no label.	1%
Tooltip → Show Tooltip	Turns the hover tooltip on or off.	On

Grouped donuts have no Sort slices by value and no Percentage decimal places. There is no Sunburst mode: for a multi-level hierarchy, use the Sunburst chart.

How it behaves

• Colours follow the slice. With Consistent member colors on (the default for new reports), slices are coloured by their Details member, so a category has the same colour in every donut. See Colors.
• Group names. Each name is drawn once in its donut's centre, and stays when filters leave only one group. In new components whose grouping-label font size was never changed, the name grows with the hole (up to 24 px). Setting a font size fixes it.
• All-zero groups. A donut whose values are all 0 is a light grey ring with All values are 0 under the group name, and gets no labels. Missing values are not zero: a group with no values draws no ring. Positive and negative values that cancel out are not treated as zero.
• Shares, not amounts. Two equal-looking slices in different donuts can stand for very different amounts, because their group totals differ. Compare the tooltip values, or pair the donuts with a total-sales chart when volume matters.
• Negative values. The tooltip share reads, for example, 25% of the absolute total.
• Label fitting. Each donut lays out its outer labels within its own area, so they never overlap the neighbours. All donuts shrink equally to make room (down to 40% of the radius), then long labels are cut with "…". If not even three characters fit, no labels are drawn. At the default 480 × 300 px with about five groups this means labels may not appear at all; enlarge the component or reduce the groups.

Opening reports made before 10.00

• A donut whose values are all 0 shows the grey ring instead of equal slices labelled 0 (0%).
• Min. proportion is now exact, so a few labels of slices just above the threshold reappear.
