## Best for

A fleet run history list where each job row holds a 20 bar strip of HoverCards with exit code and trigger, plus failing streaks

## Agent notes

- Replace `RAW_JOBS` in data.ts; `buildHistory` expands each 20 character `pattern` into runs, so map your real runs straight into `JOBS`
- `REFERENCE_MS` pins now at Sep 29, 2026 14:20 UTC for every relative time and the As of stamp; pass the current time once data is live
- `JobRow` has no click handler and no actions menu, so a job opens nothing; only each bar's `HoverCard` reveals run detail

## When not to use

- One job's durations on a single larger plot with a run trigger and an export: use [Cron Run Durations](https://reui.io/blocks/chart/bar-chart/chart-33.md) (`get_block("chart-33")`)
- A scheduler console where jobs are toggled, filtered and run or paused in bulk: use [Cron Jobs](https://reui.io/blocks/solutions/dev-ops/solution-dev-ops-1.md) (`get_block("solution-dev-ops-1")`)

## Install

```bash
npx shadcn@latest add @reui/chart-34
```

## About Status Tracker blocks

### When to use

- A fleet of cron jobs, each row charting its last 20 runs as duration bars with hover details
- Deploy pipelines and release lanes with per stage meters, promote gates and a version matrix

### When not to use

- One aggregated volume plotted per hour, with no history per row: use the [Bar Chart blocks](https://reui.io/blocks/chart/bar-chart.md)
- Summary tiles that pair a value with a mini trend and no row list: use the [Sparkline blocks](https://reui.io/blocks/chart/sparkline.md)

### Agent notes

- Rows come from constants in the block folder and `Chart` takes no props, so map your job or deploy records onto the same fields

Every ReUI item has a twin like this one; the index is https://reui.io/llms.txt. Agents with the ReUI MCP (https://reui.io/docs/mcp) get the same guidance from the getters named above.
