# RangeBarBound

Canonical page: https://www.adaptabletools.com/docs/reference/rangebarbound

Resolvable value used by a Range Bar's `Min`, `Max` or `Reference.Value`.

- `number` — a hard-coded value
- `string` — a column id; the row's value in that column is used
- `'Col-Min' | 'Col-Max' | 'Col-Avg' | 'Col-Median'` — a column-wide
 aggregate computed across visible rows

```ts title="TypeScript"
export type RangeBarBound = number | string | DynamicRangeEndpoint;
```
