# Radar

> Two profiles across the same axes. Sample data: Atlas 3 and Kite 2 Pro scored on reasoning, code, math, tool use, speed and cost.

- Type 023 · Compare items
- Component: `<Radar>`, the same name as the Figma component
- Install: `npx shadcn add @chartory/radar` (free in Hearth: the public registry, no token; Signal with Code and Complete)
- Type page: https://usechartory.com/charts/radar

## Installation

1. **Set up the registry once.** This chart is free in Hearth and MIT licensed: no token. Add @chartory to components.json once (the URL alone, no headers), or skip this when another chart is already installed. [Installation guide](https://usechartory.com/docs/installation)

2. **Add the chart.** One command adds the Radar component to your project.

```bash
npx shadcn add @chartory/radar
```

3. **Use it.** Pass your rows. The props are the Figma properties.

usage.tsx:

```tsx
import { Radar }
  from "@/components/chartory/radar"

<Radar
  data={modelScores}
  size="m"
  legend
/>
```

| Prop | Type | Default | Note |
| --- | --- | --- | --- |
| axes | string[] | Required | The axis names, in order. |
| max | number | Required | The top of the value scale. |
| series | RadarSeries[] | Required | One entry per series. |

### RadarSeries

## Radar chart: a React and Figma chart in four sizes

### What does a radar chart show?

A radar chart plots scores on axes around a centre and joins them into a shape, so two profiles compare by outline. Strengths and gaps show as bulges and dents. Use it for model scores, skill profiles and product ratings across the same criteria.

Chartory ships it as a Figma component and a React component with the same name. The code installs from the shadcn registry with one command and lands in your project as a file you own.

### What is the Radar component?

It is one **<Radar>** component. Its props are the Figma properties with the same names and values, and the props table above lists them. The data is scores on five to eight shared axes.

Sizes **XS**, **S**, **M** and **L** re-lay the chart out from the data instead of scaling it, so labels stay readable at every size.

### When should I use it?

- **Are two or three items compared?** Yes means the radar fits.
- **Is the overall shape the point?** Yes means the radar fits.
- **Do the axes share one scale?** Yes means the radar fits.

### When does another type fit better?

- **Many items across axes.** Use Parallel coordinates instead.
- **Exact gaps per axis.** Use Grouped bars instead.
- **Three measures that trade off.** Use Ternary instead.

## Radar questions

### Does the Radar chart work with shadcn/ui?

Yes. It installs through the shadcn registry with the shadcn CLI, and the file lands in your project.

### How do I install it?

It is free in Hearth and MIT licensed: add the @chartory registry URL once, no token, then run npx shadcn add @chartory/radar. The Installation guide has the steps.

### Can my coding agent install it?

Yes. Connect the Chartory MCP server and ask for the radar chart; the agent runs the same command and you review the diff.

### What data does it expect?

Scores on five to eight shared axes. The sample data comes with the component, and the props table lists every field.

### Which sizes does it ship in?

XS, S, M and L, in Figma and in code. Each size is laid out again from the data, so text and lines keep their size.

### Is it in the Figma file too?

Yes. chart/023-radar has the same properties as the component.

### Does it follow light and dark mode?

Yes. Every paint is a token, so the chart follows light and dark mode and the collection you pick.

### Which plan has the code?

None for Hearth: it is free in the public registry, no token. The Signal collection (@chartory/signal) comes with Code and Complete.
