Pie Chart without Separators

A pie whose slices meet edge to edge with no seams: a solid disc for when the colors alone tell the parts apart. For React on TanStack Charts.

Framework
Charting library

About

Use it when the slice colors contrast enough to stand on their own and you want the pie to read as one solid shape. With similar colors or many small slices, keep the separators of the plain pie.

Five browser slices fill the disc edge to edge, with no outline drawn between them: each boundary is just the meeting of two colors.

Usage

import { ChartPieSeparator } from "@/components/charts/chart-pie-separator";
<ChartPieSeparator />

Customize

  • Leaving stroke and strokeWidth off radialArc is the whole change from the plain pie, which draws a 1px seam in var(--background).
  • For space rather than a line, pie()'s gapAngle takes an angle in radians that holds at any size.
  • Slices are painted var(--color-<browser>) from chartConfig; with no seam, pick tokens that contrast with their neighbors.
  • ChartContainer is mx-auto aspect-square max-h-[250px], the same square as the plain pie.

FAQ

How are the separators removed?

The other pies give radialArc a 1px stroke in var(--background), which reads as a gap. This one leaves stroke out, and radialArc draws no outline without one, so the slices touch.

When should I keep the separators?

Keep the seam when two neighbors have similar colors, or when the slices are small: the line is what tells them apart. Remove it when the colors contrast well and you want a calmer disc.

Can I have a different gap instead?

Use pie()'s gapAngle for real space between slices, an angle in radians, or set stroke and strokeWidth on radialArc for a line of any color and width.

Two neighboring slices blend together. What now?

Change the order so similar colors aren't neighbors: sort chartData, or pass orderBy and order to pie(). Or change chartConfig's --chart-N tokens for the clashing slices.

Does anything else change?

Yes. The chart is the same plain pie, so the tooltip, keyboard focus and theming all work as before; only the seam is gone. Tab in and the arrow keys step through the slices.

API Reference

ChartContainer

<div> data-slot="chart"

PropType
configChartConfig

ariaDescription?string

The chart's accessible description.

className?string

The container's size: aspect-auto h-[250px] w-full, mx-auto aspect-square max-h-[250px]. It's aspect-video by default.

children?ReactNode

What sits under the chart inside the container: a ChartLegend.

tooltip?ChartTooltipContentProps | false

ChartTooltipContent's props (indicator, hideLabel, formatter…) for the default body, or false for TanStack's own tooltip body.

Type
ChartTooltipContentProps | false
renderTooltip?(context: ChartTooltipBodyRenderContext) => ReactNode

A whole tooltip body of your own, in place of ChartTooltipContent: it gets the focused points (each with its datum, group and color).

Type
(context: ChartTooltipBodyRenderContext) => ReactNode
defaultIndex?number

The category whose tooltip shows before any pointer, as Recharts' defaultIndex.

height?number

A fixed height in pixels for the chart, in place of the container's.

aspectRatio?number

A width-to-height ratio for the chart, in place of the container's height.

initialWidth?number

The width the chart renders at before it's measured.

onFocusChange?(point: ChartPoint | null) => void

Called as the focused point changes: a pointer, a key or a tap.

Type
(point: ChartPoint | null) => void
onFocusGroupChange?(points: readonly ChartPoint[]) => void

Called with every point at the focused category (a stacked or grouped chart's).

Type
(points: readonly ChartPoint[]) => void
onSelect?(point: ChartPoint | null) => void

Called when a point is clicked or picked with Enter.

Type
(point: ChartPoint | null) => void
CSS variableType
--color-<key>?color

Each config key's color (its theme color in light and dark), set on the container: the marks paint with var(--color-<key>).

ChartTooltipContent

<div>

PropType
pointsreadonly ChartPoint[]

The focused points, from the tooltip's context. ChartContainer passes them to its default body; a body of your own passes its context's.

indicator?"dot" | "line" | "dashed"

The indicator's shape beside each row.

Type
"dot" | "line" | "dashed"
Default
"dot"
hideLabel?boolean

Hides the label above the rows (the focused category).

Default
false
hideIndicator?boolean

Hides each row's color indicator.

Default
false
label?string

The label's text in place of the focused category, looked up in config.

labelKey?string

The datum field (or config key) the label is read from, looked up in config.

nameKey?string

The datum field (or config key) each row's series is read from: a pie's browser.

valueKey?string

The datum field each row's value is read from, for points that carry geometry rather than values (a pie's, from pie()).

color?string

One indicator color for every row, in place of each series' own.

labelFormatter?(label: string, points: readonly ChartPoint[]) => string

Formats the label (the config's label or the category), with the rows' points: a date written out, a unit.

Type
(label: string, points: readonly ChartPoint[]) => string
formatter?(value: number | string, name: string, item: ChartTooltipItem, index: number) => ReactNode

A row's content in place of its indicator, name and value, as shadcn's formatter: a unit, a currency, a total row.

Type
(value: number | string, name: string, item: ChartTooltipItem, index: number) => ReactNode
className?string

Classes for the tooltip's card.

ChartLegend

<div>

PropType
config?ChartConfig

The series to list: the container's config by default.

keys?readonly string[]

The series keys to list, in order: every key with a color by default.

hideIcon?boolean

Hides each series' icon (from config), leaving its color swatch.

Default
false
verticalAlign?"top" | "bottom"

Above the chart or under it.

Type
"top" | "bottom"

"bottom"
className?string

Classes for the legend's row.

ChartConfig

KeyType
label?string

The series' name in the tooltip and the legend.

icon?Component

An icon beside its name in the legend and the tooltip (a lucide-react icon).

color?string

Its color in both themes: a token (var(--chart-1)) or any CSS color.

theme?{ light: string; dark: string }

A color for each theme, in place of color.

Helpers

ExportType
chartTooltip?(settings?: ChartTooltipSettings) => ChartDefinitionOptions

defineChart's second argument for a chart with a tooltip: what a pointer or a key focuses (group-x, each category's series, by default), the focus ring, and the host ChartContainer draws its body in.

Type
(settings?: ChartTooltipSettings) => ChartDefinitionOptions
chartTheme?ChartTheme

chartLinearScale?() => LinearScale

A value axis drawn as Recharts draws its default one: zero in the domain, five nice ticks. Pass it as a factory: y: { scale: chartLinearScale }.
