# Shadcn Bar Chart blocks

> Bar and column charts, grouped and stacked bars, lollipop stems and segmented bar meters for comparing values.

- Type: Pro blocks (Charts)
- Page: https://reui.io/blocks/chart/bar-chart
- Blocks: 14
- Installs with a ReUI Pro or Ultimate license; setup: https://reui.io/docs/license-setup

## When to use

- Values compared across hours, days or categories as grouped, stacked or hatched columns
- Run durations or event volumes against a timeout or limit line, with outcome toggles
- Segmented meters that split a capacity, a fund or a heart rate zone into colored slices

## When not to use

- A share of a whole where the slices read better around a ring: use the [Pie Chart blocks](https://reui.io/blocks/chart/pie-chart.md)
- A progress reading shown as an arc gauge with a status label: use the [Radial Chart blocks](https://reui.io/blocks/chart/radial-chart.md)
- Rows of jobs or deploys, each with its own run history strip: use the [Status Tracker blocks](https://reui.io/blocks/chart/status-tracker.md)

## Agent notes

- `Chart` renders with no props, so every bar, meter value and limit comes from constants kept in the block folder

## Blocks

Best for a fund share bar of rounded pills sized by each fund's share, over a logo list that a Top 3, Top 5 or All Select trims and retotals.
