About
Use it to compare two profiles over the same categories: this year against last, two products, two teams. The overlap shows where they agree and the gaps where they differ. Add the legend version when nothing on the page names the two colors.
Desktop fills its shape at 60% and Mobile sits in front, fully opaque, both on a polygon grid with spokes and the month names around the edge.
Installation
Usage
import { ChartRadarMultiple } from "@/components/charts/chart-radar-multiple";<ChartRadarMultiple />Customize
- One row per month holds both values:
{ month, desktop, mobile }. Each series is its ownradialAreawithradiuson its field. - Each mark names its config key with
z: () => "desktop"(or"mobile"), so the tooltip and colors line up:var(--color-desktop)andvar(--color-mobile)come fromchartConfig. - Marks paint in array order; Mobile comes last and covers Desktop where they overlap. A
whenFocusedlayer adds each series' dot on the focused month. - Both series share one radius scale,
chartLinearScale, which rounds Desktop's 305 up to 320: one scale is what makes the two shapes comparable. tooltiponChartContainerpasses{ indicator: "line" }, so each row shows a short bar in its series color.
FAQ
How do I add a third series?
Add a radialArea with radius on the new field, a fill of var(--color-<key>) and z: () => "<key>" (the series key the tooltip reads), plus a radialDot for it in the whenFocused layer. Then add the key to chartConfig with a label and a color. Every row of chartData needs the new field.
Which series is drawn on top?
Marks paint in the order of polar()'s marks: the last one is on top. Here Mobile comes second, fully opaque, inside Desktop's 60% fill. Put the smaller series last, or lower its opacity, so neither hides the other.
How many series can I compare?
Two or three. Past that, the overlapping fills turn into one dark patch. For more series, use the lines-only radar, small separate radars, or a grouped bar chart.

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.

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.

false
label?string

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

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.

(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.

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.

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).
