Bar Chart

A bar chart component is a visual representation using rectangular bars to compare quantities across different categories or time periods.

Import

import { BarChart } from '@saas-ui/charts'

Usage

Basic

Basic composition with Card and Heading components. BarChart requires a fixed height (eg height="300px") to render properly.

import { Card, CardBody, CardHeader, Heading } from '@chakra-ui/react'
import { BarChart } from '@saas-ui/charts'


const valueFormatter = (value) => {
  return new Intl.NumberFormat('en-US', {
    style: 'currency',
    currency: 'USD',
  }).format(value)
}


export default function Page() {
  return (
    <Card>
      <CardHeader pb="0">
        <Heading as="h4" fontWeight="medium" size="md">
          Revenue over time
        </Heading>
      </CardHeader>
      <CardBody>
        <BarChart
          data={data}
          categories={['Revenue']}
          valueFormatter={valueFormatter}
          yAxisWidth={80}
          height="300px"
        />
      </CardBody>
    </Card>
  )
}


const data = [
  {
    date: 'Jan 1',
    Revenue: 1475,
  },
  {
    date: 'Jan 8',
    Revenue: 1936,

Multiple categories

Multiple categories can be displayed in the same chart. Categories map to the data object keys.

import { Card, CardBody, CardHeader, Heading } from '@chakra-ui/react'
import { BarChart } from '@saas-ui/charts'


export default function Page() {
  return (
    <Card>
      <CardHeader pb="0">
        <Heading as="h4" fontWeight="medium" size="md">
          Developers
        </Heading>
      </CardHeader>
      <CardBody>
        <BarChart
          data={data}
          categories={['Backend', 'Frontend']}
          height="300px"
        />
      </CardBody>

Stacked

Categories can be stacked using the stack prop. Stacked charts are useful for displaying cumulative data of multiple categories over time.
