# Underwater drawdown

> How far below the last peak, and for how long. Sample data: fund drawdown, January to October, max −16.5%.

- Type 080 · Change over time
- Component: `<UnderwaterDrawdown>`, the same name as the Figma component
- Install: `npx shadcn add @chartory/underwater-drawdown` (free in Hearth: the public registry, no token; Signal with Code and Complete)
- Type page: https://usechartory.com/charts/underwater-drawdown

## 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 Underwater drawdown component to your project.

```bash
npx shadcn add @chartory/underwater-drawdown
```

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

usage.tsx:

```tsx
import { UnderwaterDrawdown }
  from "@/components/chartory/underwater-drawdown"

<UnderwaterDrawdown
  data={fundDrawdown}
  size="m"
  legend
/>
```

## Props

Every prop but data is a Figma property with the same name and values.

| --- | --- | --- | --- |
| data | UnderwaterDrawdownData | Required | The chart's data. The tables below list every field. |
| size | "xs" \| "s" \| "m" \| "l" | "m" | The size class. Each one is laid out again from the data. |
| legend | boolean | true | Shows the legend row under the plot. |

### UnderwaterDrawdownData

| Prop | Type | Default | Note |
| --- | --- | --- | --- |
| vals | number[] | Required | The values, in order. |
| min | number | Required | The bottom of the value scale. |
| ticks | string[] | Required | The axis tick labels. |
| xl | Record<number, string> | Required | The x axis labels, by index. |
| mark | UnderwaterDrawdownMark | Required | A marked point: where and its label. |

### UnderwaterDrawdownMark

## Underwater drawdown chart: a React and Figma chart in four sizes

### What does an underwater drawdown chart show?

An underwater drawdown chart shows how far a value sits below its previous high at every point. Zero means a new peak; the deeper the fill, the bigger the loss. Use it for funds, portfolios and any balance where recovery time matters.

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 Underwater drawdown component?

It is one **<UnderwaterDrawdown>** component. Its props are the Figma properties with the same names and values, and the props table above lists them. The data is drawdown per point and the deepest point.

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?

- **Is the loss from the peak the point?** Yes means the underwater drawdown fits.
- **Is it over time?** Yes means the underwater drawdown fits.
- **Is it one series?** Yes means the underwater drawdown fits.

### When does another type fit better?

- **The value itself.** Use Area chart instead.
- **Steps between two totals.** Use Waterfall instead.
- **Several funds compared.** Use Multi-line chart instead.

## Drawdown questions

### Does the Underwater drawdown 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/underwater-drawdown. The Installation guide has the steps.

### Can my coding agent install it?

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

### What data does it expect?

Drawdown per point and the deepest point. 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/080-underwater-fund 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.
