How do I overlay multiple series?

Render one <Radar> per series, each with its own dataKey and fill="var(--color-…)", and add <ChartLegend content={<ChartLegendContent />} /> to label them. Keep fillOpacity around 0.6 so the overlapping shapes stay readable. The Multiple series example shows two profiles.

Shadcn Radar Chart

Free shadcn/ui radar chart for React — built on Recharts and themed with CSS variables. Filled, dots, lines-only, multiple series, and circular-grid variants, plus loading, empty, and accessible states.

Installation

1 Configure registry — once per project

{
  "registries": {
    "@designrevision": "https://registry.designrevision.com/r/{name}.json"
  }
}

Add to your existing components.json. Requires shadcn/ui v2.3+.

Props

config* = —

ChartConfig

Maps each data key to { label, icon?, color }. Colors become --color-<key> CSS vars.

children* = —

React.ReactElement (a Recharts chart)

A single Recharts chart (BarChart, LineChart, …) — ChartContainer wraps it in a ResponsiveContainer.

A Recharts wrapper themed with CSS variables. Pass a `config` (ChartConfig: each data key → { label, icon?, color }) to <ChartContainer>; it injects --color-<key> vars (scoped per light/dark theme) that your Recharts series reference as fill="var(--color-desktop)". Use <ChartTooltip content={<ChartTooltipContent />}> and <ChartLegend content={<ChartLegendContent />}> for themed tooltips/legends. Colors default to the --chart-1..5 tokens, which re-theme automatically in dark mode. The container needs a height — keep aspect-video / min-h-* or ResponsiveContainer measures 0. This is the base primitive; the Bar/Line/Area/Pie/Radar/Radial chart pages compose it.

The Shadcn Radar Chart is a Recharts RadarChart wrapped in the shadcn ChartContainer — themed with your --chart CSS variables and dark-mode-ready. It plots several metrics on a shared scale around a circle, ideal for multi-axis profiles — skills, features, competitor scores. Below: filled, dots, lines-only, multiple series, and a circular-grid variant, plus the production states.

The basic radar chart

const chartConfig = {
  desktop: { label: "Desktop", color: "var(--chart-1)" },
} satisfies ChartConfig

<ChartContainer config={chartConfig} className="mx-auto aspect-square max-h-[250px]">
  <RadarChart data={chartData}>
    <ChartTooltip cursor={false} content={<ChartTooltipContent />} />
    <PolarAngleAxis dataKey="month" />
    <PolarGrid />
    <Radar dataKey="desktop" fill="var(--color-desktop)" fillOpacity={0.6} />
  </RadarChart>
</ChartContainer>

PolarAngleAxis draws the spokes (one per data row), PolarGrid the rings, and Radar the filled profile.

Multiple series

Overlay one <Radar> per series and add a legend — keep fillOpacity low so the shapes read through each other:

<Radar dataKey="desktop" fill="var(--color-desktop)" fillOpacity={0.6} />
<Radar dataKey="mobile"  fill="var(--color-mobile)"  fillOpacity={0.6} />
<ChartLegend content={<ChartLegendContent />} />

Variants

Dots — dot={{ r: 4, fillOpacity: 1 }} marks each vertex.
Lines only — fillOpacity={0} + a stroke gives just the outline (pair with PolarGrid radialLines={false}).
Circular grid — PolarGrid gridType="circle" swaps the polygon rings for circles.

Production states

Loading (circular skeleton), empty (icon + message), and accessible (role/aria-label + data-table fallback) variants are included.

See Shadcn Charts for the theming system, dark mode, and the other chart types.

Frequently asked questions

Install the chart component (npx shadcn add chart), define a ChartConfig, and compose a Recharts RadarChart inside ChartContainer with a PolarAngleAxis (the spokes), a PolarGrid (the rings), and a . The Radar Chart example is the starting point.

Radar charts compare several variables on a shared scale at a glance — skill or feature profiles, competitor scoring, product comparisons. Each axis is one metric; the filled shape is the profile. They work best with 5-8 axes and a few series; with many series the overlaps get noisy.

Render one per series, each with its own dataKey and fill="var(--color-…)", and add } /> to label them. Keep fillOpacity around 0.6 so the overlapping shapes stay readable. The Multiple series example shows two profiles.

Set the Radar's fillOpacity to 0 and give it a stroke="var(--color-…)" with a strokeWidth — you get just the outline. The Lines Only example also drops the radial grid lines with PolarGrid radialLines={false}.

PolarGrid defaults to a polygon that follows the axes. Set gridType="circle" for concentric circles instead — the Circular grid example. You can also hide the spokes with radialLines={false}.

Pass dot={{ r: 4, fillOpacity: 1 }} to the Radar — it marks each axis value. The With dots example shows it.
