# Incident tape

> One incident, minute by minute. Sample data: P95 run time during one incident, 09:30 to 10:40, first over 8 s at 09:42, 6 min from alert to acknowledged.

- Type 110 · Change over time
- Component: `<IncidentTape>`, the same name as the Figma component
- Install: `npx shadcn add @chartory/incident-tape` (Code and Complete plans)
- Type page: https://usechartory.com/charts/incident-tape

## Installation

1. **Set up the registry once.** Your token in .env and @chartory in components.json. Skip this when another chart is already installed. [Installation guide](https://usechartory.com/docs/installation)

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

```bash
npx shadcn add @chartory/incident-tape
```

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

usage.tsx:

```tsx
import { IncidentTape }
  from "@/components/chartory/incident-tape"

<IncidentTape
  data={incidentSteps}
  size="m"
  legend
/>
```

## Incident tape chart: a React and Figma chart in four sizes

### What does an incident tape chart show?

An incident tape chart lays the steps of an incident along the measure that triggered it: rising, over the limit, alert, paged, acknowledged, fix proposed. Gaps between steps show where time was lost. Use it for incident reviews and on-call reports.

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 Incident tape component?

It is one **<IncidentTape>** component. Its props are the Figma properties with the same names and values, and the props table above lists them. The data is a measure over time and dated steps.

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 it one incident?** Yes means the incident tape fits.
- **Do the steps matter?** Yes means the incident tape fits.
- **Is it minutes, not days?** Yes means the incident tape fits.

### When does another type fit better?

- **Many incidents over a month.** Use Burn-down instead.
- **Only the measure against target.** Use Target trend instead.
- **A schedule over days.** Use Gantt instead.

## Incident tape questions

### Does the Incident tape 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?

Add your token and the @chartory registry once, then run npx shadcn add @chartory/incident-tape. The Installation guide has the steps.

### Can my coding agent install it?

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

### What data does it expect?

A measure over time and dated steps. 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/110-incident-tape 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?

Code and Complete. Figma has the Figma file only.
