Bar Chart

A flexible bar chart component for visualizing categorical data with support for multiple variants including horizontal, stacked, grouped, and interactive layouts.

"use client"

import { BarChart } from "@/components/ui/charts"

// Page view data - 30 days of traffic
const chartData = [
  186, 205, 237, 173, 209, 214, 278, 312, 245, 289, 234, 276, 198, 267, 289,
  312, 256, 234, 289, 267, 298, 312, 278, 256, 234, 267, 289, 312, 334, 356,
].map((value, i) => ({
  label: `${i + 1}`,
  value,
}))

export function BarChartDemo() {
  return (
    <BarChart
      data={chartData}
      color="#2563eb"
      showGrid
      showTooltip
      barRadius={0}
      aspectRatio={2.5}
    />
  )
}

About

The Bar Chart component is built on top of Recharts and provides a simple, declarative way to create bar charts. It supports various configurations including:

Vertical and horizontal orientations
Single and multiple data series
Stacked and grouped bar layouts
Custom tooltips with theme-aware styling
Responsive design that adapts to container width

Installation


pnpm dlx shadcn@latest add https://ui.simplifying.ai/r/bar-chart.json

Usage

import { BarChart } from "@/components/ui/charts"
 
const data = [
  { label: "Jan", value: 4000 },
  { label: "Feb", value: 3000 },
  { label: "Mar", value: 5000 },
]
 
export function MyChart() {
  return <BarChart data={data} />
}

Examples

Default

The default bar chart displays categorical data with sharp-edged bars, horizontal grid lines, and an interactive tooltip on hover.

"use client"

import { BarChart } from "@/components/ui/charts"

// Page view data - 30 days of traffic
const chartData = [
  186, 205, 237, 173, 209, 214, 278, 312, 245, 289, 234, 276, 198, 267, 289,
  312, 256, 234, 289, 267, 298, 312, 278, 256, 234, 267, 289, 312, 334, 356,
].map((value, i) => ({
  label: `${i + 1}`,
  value,
}))

export function BarChartDemo() {
  return (
    <BarChart
      data={chartData}
      color="#2563eb"
      showGrid
      showTooltip
      barRadius={0}
      aspectRatio={2.5}
    />
  )
}

With Labels

Use the showLabel prop to display values directly on top of each bar. This is useful when you want to show exact values without requiring users to hover.

Horizontal

Horizontal bar charts are ideal for displaying data with long category names or when you have many categories. Use layout="vertical" to switch orientation (Recharts naming convention).

<BarChart data={data} layout="vertical" />

Multiple / Grouped

Display multiple data series side-by-side to compare different metrics across categories. Use the MultiBarChart component with a series configuration.

Negative Values

Bar charts can display both positive and negative values. Bars automatically extend above or below the zero reference line.

Data Types

// Single series data point
interface BarChartDataPoint {
  label: string // Category name (e.g., "January")
  value: number // Numeric value
  fill?: string // Optional: override color for this bar
}
 
// Multiple series data point
interface MultiBarChartDataPoint {
  label: string // Category name
  [key: string]: string | number // Dynamic keys for each series
}
 
// Series configuration
interface MultiBarChartSeries {
  name: string // Display name in tooltip/legend
  dataKey: string // Key in data object
  color: string // Bar fill color
  stackId?: string // Optional: group into stack
}

Customization

Custom Colors

Pass a color prop or use per-bar colors via the fill property in data:

const data = [
  { label: "Success", value: 80, fill: "#22c55e" },
  { label: "Warning", value: 15, fill: "#eab308" },
  { label: "Error", value: 5, fill: "#ef4444" },
]
 
<BarChart data={data} />

For advanced tooltip customization, use the Recharts components directly:

import { Bar, BarChart, Tooltip } from "recharts"
 
;<BarChart data={data}>
  <Tooltip
    content={({ active, payload }) => (
      <div className="custom-tooltip">{/* Your custom content */}</div>
    )}
  />
  <Bar dataKey="value" />
</BarChart>

Accessibility

Charts include proper ARIA labels
Tooltips are keyboard accessible
Color schemes maintain sufficient contrast
Grid lines help users track values across the chart

Notes

Bar charts are best suited for comparing categorical data across different groups
Use horizontal layout (layout="vertical") when dealing with long category labels
Stacked bar charts are ideal for showing part-to-whole relationships over categories
The MultiBarChart component automatically handles legend generation and color coordination
For time-series data with many points, consider using a line or area chart instead
Bar radius can be adjusted for different visual styles (sharp edges vs rounded corners)
