- Type 002 · Compare items
- Component: `<GroupedBars>`, the same name as the Figma component
- Install: `npx shadcn add @chartory/grouped-bars` (free in Hearth: the public registry, no token; Signal with Code and Complete)
- Type page: https://usechartory.com/charts/grouped-bars

## Installation

1. **No setup needed.** This chart is free in Hearth and MIT licensed: no token. @chartory is in the shadcn registry directory, so the CLI finds it without a components.json entry. [Installation guide](https://usechartory.com/docs/installation)

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

```bash
npx shadcn add @chartory/grouped-bars
```

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

usage.tsx:

```tsx
import { GroupedBars }
  from "@/components/chartory/grouped-bars"

<GroupedBars
  data={paidByPlan}
  size="m"
  legend
/>
```

## Grouped bar chart: a React and Figma chart in four sizes

### What does a grouped bar chart show?

A grouped bar chart places a small set of bars in each period, one per series, so you can compare the series inside a period and follow each one across periods. Use it for plans, regions or products counted the same way.

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 Grouped bars component?

It is one **<GroupedBars>** component. Its props are the Figma properties with the same names and values, and the props table above lists them. The data is two to four series, one value per period.

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?

- **Do you compare series inside each period?** Yes means the grouped bars fit.
- **Are there four series or fewer?** Yes means the grouped bars fit.
- **Are the periods few?** Yes means the grouped bars fit.

### When does another type fit better?

- **The total per period matters.** Use Stacked bars instead.
- **Too many bars per group.** Use Multi-line chart instead.
- **Many periods read better as lines.** Use Multi-line chart instead.

## Grouped bar questions

### Does the Grouped bars 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: run npx shadcn add @chartory/grouped-bars, with no token and no setup (@chartory is in the shadcn registry directory). The Installation guide has the steps.

### Can my coding agent install it?

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

### What data does it expect?

Two to four series, one value per period. 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/002-grouped-bars 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.
