Radar Chart
Compare a product to the market, or this quarter to last, across the same measures on one shared zero-based scale. Filled shapes are a light wash with a 2px edge so overlaps stay readable; Outline suits three series.
The decision inside it
Every axis shares one scale
A radar whose axes use different scales draws a shape that means nothing, so the scale starts at zero and ends at one max for all of them.
When to use it
Use Radar Chart to compare two or three things across the same five to eight measures on one scale. For more series use grouped bars instead.
Installation
How you get it
Paste this into Claude Code, Cursor, Codex or any coding agent. It installs the file and uses it as it is, instead of writing a new one.
Use Layro's Radar Chart for this.
Install it: npx shadcn@latest add @layro/radar-chart
(the @layro registry is set up in components.json, with LAYRO_KEY in .env.local)
Import it from @/components/ui/radar-chart.
Do not rewrite or restyle it. Pass my data through its props
and keep its built-in states.For the full brief with every prop and the mistakes assistants usually make, use Copy prompt above. Pro components install through the @layro registry with your CLI token: see the Namespaced tab.
Usage
import { RadarChart } from "@/components/ui/radar-chart";
const data = [
{ measure: "Speed", us: 88, market: 64 },
{ measure: "Mobile", us: 92, market: 70 },
{ measure: "Templates", us: 74, market: 78 },
{ measure: "Price", us: 70, market: 58 },
{ measure: "Audit trail", us: 95, market: 66 },
];
export function Ratings() {
return (
<RadarChart
data={data}
axisKey="measure"
max={100}
description="Our ratings against the market average"
series={[
{ key: "us", label: "Us" },
{ key: "market", label: "Market average", slot: 3 },
]}
/>
);
