Bar Chart

A bar chart made of markup: each bar's height is a percentage in a CSS variable rather than SVG. The chart stays text, so it scales and prints.

# Install and place "chart-002" (Bar Chart) from VibeUI

## 1. Install first — do not skip, do not recreate
Run this exact command before writing any code:
npx shadcn@latest add https://vibeui.ru/r/chart-002.json

Registry item: https://vibeui.ru/r/chart-002.json
Installs to: components/vibeui/chart-002.tsx (the exact path follows this project's components.json aliases).
npm dependencies: none.
Registry dependencies: none.

Install it from the registry. Do not recreate it from the description,
do not substitute a similar component from another library, and do not
rewrite it to match the project's existing style.

## 2. What it is
A bar chart made of markup: each bar's height is a percentage in a CSS variable rather than SVG. The chart stays text, so it scales and prints.

A bar chart built from markup: values above the bars, one bar highlighted in the accent, hover shading and axis labels. The height comes from a percentage in a CSS variable, so neither SVG nor a charting library is needed. Zero dependencies, one file, its own palette, no client JS.

## 3. How to use it
import { Chart002 } from "@/components/vibeui/chart-002"

<Chart002
  title="Installs by month"
  bars={[{ label: "Feb", value: 86 }, { label: "Mar", value: 118, highlight: true }]}
/>

Read the installed file for the full prop list.

## 4. Where to place it
This is a small inline component. Put it exactly where the user asked,
inside the existing markup. Do not create a new page, section or
wrapper for it. If a similar control already sits in that spot,
replace it instead of adding a second one.

Placement: ___
(The user fills this line in. If it is still blank, ask where to put it
instead of guessing.)

## 5. Keep exactly as installed
- the local --vibeui-chart-002-* palette — do not swap it for your theme tokens (bg-primary, --chart-1 and the like)
- the percentage-driven bar height: converting to pixels breaks whenever the plot height changes
- the min-height on a bar — otherwise a zero value disappears and the data looks missing
- the grid as a background of the plot area rather than elements: it then stays out of the bars' layout
- the hidden label and value inside each bar together with aria-hidden on the axis — otherwise a screen reader reads the labels twice
- highlighting a bar through a data attribute rather than a colour in the data
- the <style> block inside the component — it holds the palette, the grid and the bars

## 6. You may change
- the bars array: label, value and the highlight flag
- title — the chart heading
- unit — the unit beside the values
- showValues — whether numbers appear above the bars
- the accent through the accent prop — it colours the highlighted bar
- the plot height through --vibeui-chart-002-height and outer spacing through className

## 7. Rules
- More than twelve bars will not fit: the labels start colliding.
- The axis always starts at zero, as it should. A truncated scale exaggerates the difference.
- Comparing two series needs a different component: grouped bars require a legend.
- Do not lift the CSS variables into globals.css: the component has to stay a single file.

## 8. Verify
- it renders with no console errors;
- it looks like the preview on the VibeUI page you copied this from;
- if it does not, you changed something listed in section 5 — put it back.

For developers

npx shadcn@latest add https://vibeui.ru/r/chart-002.json
https://vibeui.ru/r/chart-002.json

Компонент самодостаточен: один файл, без зависимостей, собственная палитра в локальных переменных --vibeui-chart-002-*. Столбцы — обычные элементы во flex-раскладке; высота каждого приходит переменной --vibeui-chart-002-bar-height в процентах от максимума. Сетка нарисована повторяющимся градиентом фона области, а не отдельными элементами. Подписи оси помечены aria-hidden, потому что каждое значение уже прочитано скрытым текстом внутри столбца.

Component source

The same file your agent installs. Here in case you would rather copy it by hand.

import type { CSSProperties } from "react"

export type Chart002Bar = {
  label: string
  value: number
  /** Выделить столбец: текущий период, план, аномалия. */
  highlight?: boolean
}

export type Chart002Props = {
  bars?: Chart002Bar[]
  title?: string
  unit?: string
  /** Показывать значение над столбцом. */
  showValues?: boolean
  accent?: string
  className?: string
  style?: CSSProperties
}

// Идея компонента: столбцы — это раскладка, а не рисунок. Высота задаётся
// процентом в CSS-переменной каждого столбца, поэтому график остаётся
// текстом и разметкой: он масштабируется, копируется и печатается, а SVG
// и библиотека графиков не нужны.
