# Audit Log Volume block

> Audit log event volume chart with stacked outcome pills, drag range selection and denial avatars

## Best for

Audit events in 5 minute to daily buckets, where a dragged span totals its outcomes and top actor and faces mark unreviewed denials

## Agent notes

- Replace `EVENTS` (anchors plus 6,000 rows, each with a `category`) and `ACTORS`, and point `refresh` at your audit API; windows count back from `REFERENCE_DATE`
- A committed `selection` scopes the plot, readout, `StatStrip` and every export, but nothing outside `Chart` reads it; lift it to filter your list
- `DenialLane` faces mark denied events with no `reviewedBy`, so set that field once a denial is reviewed or it stays flagged

## When not to use

- Job runner time per hour split by outcome, with a timeout burn callout: use [Cron Runner Load](https://web.dev.reui.io/blocks/chart/bar-chart/chart-32.md) (`get_block("chart-32")`)
- The individual access entries grouped by day, each expanding to its details: use [Access Audit Log](https://web.dev.reui.io/blocks/solutions/users/solution-users-6.md) (`get_block("solution-users-6")`)

## About Bar Chart blocks

### When to use

- Amounts compared across years, weeks, categories or regions as prisms, patterned bars, pills or lanes
- Activity over time stacked by outcome, such as job runs, audit events, firewall requests or data syncs
- Run durations and error budgets read against a timeout, a warning line or a paging threshold

### When not to use

- A share of a whole where the slices read better around a ring: use the [Pie Chart blocks](https://web.dev.reui.io/blocks/chart/pie-chart.md)
- A capacity or allocation split into colored segments on one meter, with no axis: use the [Stats blocks](https://web.dev.reui.io/blocks/application/stats.md)
- Rows of jobs or deploys, each with its own run history strip: use the [Status Tracker blocks](https://web.dev.reui.io/blocks/chart/status-tracker.md)

### Agent notes

- `Chart` renders with no props and fetches nothing, so every bar, lane and limit is seeded from constants in the block folder
