Pie
The Pie card controls the shape of the chart, the size of the hole, the geometry of the slices and which dimension the data-driven colors are applied to.
Shape
| Setting | Result |
|---|---|
| Full circle (default) | The series is laid out over 360°, starting at 12 o'clock |
| Top half circle | The series is laid out over 180°, from 9 o'clock to 3 o'clock through the top |
| Bottom half circle | The series is laid out over 180°, from 3 o'clock to 9 o'clock through the bottom |
A half circle is not a cropped pie. The whole series is spread over 180°, so a 70 % slice takes 126° of the half circle — a half donut therefore reads as a gauge without any dummy "remainder" category.
The drawn half stays optically centred in the space available: the visual pushes the centre of the circle off the middle of the box so the visible half is not stranded against an edge.
Chart Type
Two ways of drawing the categories of one chart:
| Setting | Result |
|---|---|
| Slices (default) | The categories share the circle, each taking its proportion of the total — the pie / donut reading |
| Concentric rings | One ring per category, each starting at zero and drawn in proportion to the largest value, which fills the whole circle — radial bars |
Concentric rings answers a different question. A pie shows how a whole is split; concentric rings compare magnitudes that do not add up to anything — five brands measured on their own scale, six indicators out of 100. Nothing is normalised to 100 %: each ring is a bar wrapped around the centre.
On a half circle, the largest value fills the half rather than the full turn.
The rings carry the categories, so they are named by the legend. When a Legend field is present, the series are separated the same way as for slices — one chart per series in a grid, each with its own title. See Multiple Series for the nesting order and the shared scale.
Geometry
| Property | Description | Default |
|---|---|---|
| Start Angle | Rotates the whole chart, in degrees | 0 |
| Direction | Clockwise or Counter-clockwise ordering of the slices | Clockwise |
| Inner Radius | 0 % is a pie; anything above turns it into a donut | 0 % |
| Slice Gap (°) | Angular gap between neighbouring slices | 0 |
| Corner Radius (px) | Rounds the corners of every slice | 0 |
| Slice Border Color | Stroke drawn around each slice | White |
| Slice Border Width | 0 removes the stroke | 1 |
Raising the Inner Radius above 0 also unlocks the Center Label card, whose text would otherwise be covered by the slices. In the concentric type the rings carve up the radius themselves, so the hole is optional there and the center label is always available.
Slice Gap is hidden in the concentric type: every category owns its ring, so there is no neighbour to be separated from.
Slice Logo
The Logo field well feeds three places at once. On the slices themselves it is read per category — a slice is a category, so it carries the same image as its legend entry.
Because the image describes the category, a plain column works here: the Pie Chart is the one visual of the suite that declares the Logo role on its category axis. See Column or measure? — a logo that describes the legend value instead, such as a flag on a grid of small multiples, still has to be a measure.
| Setting | Result |
|---|---|
| None (default) | No image on the slices |
| Inside | The logo sits in the middle of the ring band, on the bisector of the slice |
| Outside | The logo sits past the outer edge, on the same bisector |
| Property | Description | Default |
|---|---|---|
| Slice Logo Size (px) | Side of the square the image is fitted into | 20 |
| Slice Logo Offset (px) | Gap between the outer edge and an outside logo | 6 |
A logo is skipped when it does not fit: the arc has to be wider than the image at the logo radius, and an inside logo also needs a ring thicker than itself. A thin slice therefore keeps its color and its label rather than disappearing under an image larger than the slice — there is no threshold to set.
With Outside, the room the logos need is taken out of the radius, so they never overflow the visual. With Inside, an inside data label is pushed outward by half the logo so the two share the band instead of overlapping.
The other two places the same field feeds are the legend, read per category, and the series titles of the small multiples, read per legend value.
Slice Order
| Setting | Result |
|---|---|
| Data order (default) | The order coming out of the model, including any sort applied to the visual |
| Largest first | Slices sorted by descending value |
| Smallest first | Slices sorted by ascending value |
With several series, the rank is resolved once, on the totals across every series, and the same order is applied to every chart. Sorting each ring on its own value would put the same category at a different place on each ring and make the charts uncomparable.
Apply colors to
The Series Color field feeds one dimension at a time — either the slices or the charts, never both. This dropdown decides which, and the legend follows it.
| Setting | Slice colors come from | The legend lists |
|---|---|---|
| Categories (default) | The Series Color field read per category | The categories |
| Series | The Series Color field read per legend value | The series |
In either mode the resolution order is the same: conditional formatting (fx) first, then the Series Color field, then the report theme palette, then the built-in fallback palette. See Data Colors.
