Radial Chart with Grid

Five browser rings over circular grid lines and spokes, with no track behind them, so you read each arc against the grid. In React on TanStack Charts.

About

Use it when readers judge each ring by how far it gets around the circle and need marks to measure against. The circles and spokes do the job the track does in the plain radial chart, without filling the card with gray. For exact comparisons, a horizontal bar chart is still easier.

Five rings, Chrome innermost, each start at three o'clock and run counterclockwise as far as their visitor counts. A thin circle sits at every ring's radius and spokes cross them at even steps of the value scale.

Usage

import { ChartRadialGrid } from "@/components/charts/chart-radial-grid";
<ChartRadialGrid />

Customize

  • The rings are the plain radial chart's minus the track: one radialBarAngle with radius on the browser band and angle on visitors, reading the pointer itself.
  • radialGrid() with no options draws a circle through the middle of each browser's ring: its values default to the radius scale's bands, and circle is its default shape.
  • The spokes are a radialRule over scaleLinear().domain([0, maxVisitors]).ticks(), every 20 visitors from 0 to 260, drawn from 30 to 100 pixels on a pixels radius scale. angleGrid() is the guide version, which runs spokes from the center to the rim.
  • radialGrid and radialRule both take stroke, strokeOpacity and strokeDasharray. The grid takes var(--border) from chartTheme; the rule sets it itself.
  • The radius scale's range is [30, 100], upstream's outerRadius={100}: 10 pixels short of the plain version.

FAQ

How are the circles and spokes drawn?

The circles are a radialGrid() guide in polar()'s guides: one circle through the middle of each browser's ring, in the theme's var(--border). The spokes are a radialRule mark on the angle scale's ticks, from 30 to 100 pixels, stroked var(--border). Guides paint first and the rule comes before the bars in marks, so the rings sit on top.

How do I keep the circles and remove the spokes?

Delete the radialRule mark and keep the radialGrid() guide. To thin the spokes out instead, ask for fewer ticks, .ticks(5), or pass your own values: they're positions on the angle scale, from 0 to 275 here.

Can I add a track behind each ring?

Do what the plain Radial Chart does: a radialBarAngle with angle2: maxVisitors and fill: "var(--muted)" for every row, with the colored rings in a decorative() layer over it so the pointer reads the tracks. With a track, the grid becomes noise; most charts keep one or the other.

How do I resize the rings?

The rings run from 30 to 100 pixels from the center, 10 less than the plain version, as upstream has them. Change the radius scale's range to resize them, and the spokes' radius1 and radius2 with it. Keep mx-auto aspect-square max-h-[250px] on ChartContainer so the circles stay round.

Does the grid follow dark mode?

The grid uses the border token, which your theme defines for light and dark, so the lines dim with the page. The rings use --chart-1 to --chart-5 through chartConfig, which switch too.

API Reference

ariaDescription?string

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.

(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[]

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

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

chartTheme?ChartTheme

defineChart's theme in the site's tokens: the text, the grid and the palette (--chart-1 to --chart-5).

chartColors?(config: ChartConfig, keys?: readonly string[]) => { domain: string[]; range: string[] }

defineChart's color: each series key (in config order, or keys') painted var(--color-<key>), for marks with a color channel.

Type
(config: ChartConfig, keys?: readonly string[]) => { domain: string[]; range: string[] }
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 }.
