## Burn-rate tracks: a React and Figma chart in four sizes

### What does a burn-rate tracks show?

Burn-rate tracks show how fast an error budget is being spent over several windows at once, with the alert rule marked on the windows that have one. A short window catches spikes, a long one catches slow leaks. Use it for SLO alerting and on-call reviews.

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 Burn-rate tracks component?

It is one **<BurnRateTracks>** component. Its props are the Figma properties with the same names and values, and the props table above lists them. The data is a burn rate and a rule per window.

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 several windows compared?** Yes means the burn-rate tracks fit.
- **Does each window have a rule?** Yes means the burn-rate tracks fit.
- **Is it the rate now?** Yes means the burn-rate tracks fit.

### When does another type fit better?

- **One budget over the month.** Use Burn-down instead.
- **Plain rates side by side.** Use Horizontal bars instead.
- **The rate over time.** Use Target trend instead.

## Burn-rate questions

### Does the Burn-rate tracks 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/burn-rate-tracks. The Installation guide has the steps.

### Can my coding agent install it?

Yes. Connect the Chartory MCP server and ask for the burn-rate tracks chart; the agent runs the same command and you review the diff.

### What data does it expect?

A burn rate and a rule per window. 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/114-burn-rate-tracks 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.
