About
Most radars hide their scale. This one prints it: the ring values run up one spoke, so people can tell that a corner sits near 240 without hovering. Use it for analytical views or when several radars need to share a visible scale.
Desktop and Mobile overlap on four polygon rings at 80, 160, 240 and 320, the numbers set along a tilted spoke in the foreground color. There are no month names at the edge; the tooltip gives the values per month.
Installation
Usage
import { ChartRadarRadius } from "@/components/charts/chart-radar-radius";<ChartRadarRadius />Customize
radialGrid({ labels: true, shape: "polygon" })draws a ring on each of the radius scale's ticks and prints its value.labelAngle: Math.PI / 6andlabelRotate: 30place and turn the labels;labelFill: "var(--foreground)"colors them.angleGrid({ labels: false })draws the spokes without the month names: the radius labels are the only text.chartLinearScalerounds the top value, 305, up to 320 and ticks every 80, so the printed values sit on the rings.
FAQ
How are the radius values drawn?
radialGrid takes labels: true, which prints each ring's value. labelAngle: Math.PI / 6 puts them on a line 30 degrees clockwise from the top, between January and February, and labelRotate: 30 turns the text with it.
How do I move the values to another spoke?
Change labelAngle, in radians from twelve o'clock going clockwise: 0 puts the scale straight up, Math.PI straight down.
How do I change the numbers on the axis?
The rings and their labels both come from the radius scale's ticks: 0 to 320 in steps of 80 here. Pass the guide values for others, or format to print them as 1.2k or a percent.
API Reference
ChartContainer
<div> data-slot="chart"

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
--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>
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>
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"- Default
"bottom"
className?string
Classes for the legend's row.
ChartConfig
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
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
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 }.
- Type
() => LinearScale
curveNatural?CurveFactory
D3's natural curve, for a smooth line or area: curve: d3Curve(curveNatural).
curveStep?CurveFactory
D3's step curve, for a line or area that holds each value: curve: d3Curve(curveStep).
curveMonotoneX?CurveFactory
D3's monotone curve, smooth without overshooting a point: curve: d3Curve(curveMonotoneX).
curveLinearClosed?CurveFactory
D3's closed linear curve: a radar's polygon (curve: curveLinearClosed on radialLine and radialArea).
useChart?() => { config: ChartConfig }
The config of the ChartContainer around a component of your own (a custom tooltip body or legend).
- Type
() => { config: ChartConfig }
