Sparkline

A sparkline component is a minimalist, inline graphic displaying trends or variations.

Import

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

Usage

Basic

Basic composition with Card and Stat components. Sparkline requires a fixed height (eg height="60px") to render properly.

import {
  Card,
  CardBody,
  Stat,
  StatLabel,
  StatArrow,
  StatNumber,
} from '@chakra-ui/react'
import { Sparkline } from '@saas-ui/charts'


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


export default function Page() {
  return (
    <Card width="300px">
      <CardBody>
        <Stat>
          <StatLabel>Revenue</StatLabel>
          <StatNumber>
            {currencyFormatter(data[data.length - 1].value ?? 0)}
          </StatNumber>
          <Sparkline data={data} height="60px" mx="-4" />
        </Stat>
      </CardBody>
    </Card>
  )
}


const data = [
  {
    date: 'Jan 1',
    value: 1475,
  },
  {
    date: 'Jan 8',
    value: 1936,
  },
  {
    date: 'Jan 15',
    value: 1555,

  {
    date: 'Feb 12',
    value: 1736,
  },
  {
    date: 'Feb 19',
    value: 1981,
  },
  {
    date: 'Feb 26',

    value: 2840,
  },
  {
    date: 'May 7',
    value: 3299,
  },

    date: 'May 14',
    value: 3487,

Multiple categories

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

import {
  Card,
  CardBody,
  Stat,
  StatLabel,
  StatHelpText,
  StatArrow,
  StatNumber,
} from '@chakra-ui/react'
import { Sparkline } from '@saas-ui/charts'


export default function Page() {
  const value = Number(data[data.length - 1].value ?? 0)
  const compareValue = Number(data[data.length - 1].compareValue ?? 0)


  const percentage = Math.round(((value - compareValue) / value) * 100)


  return (
    <Card width="300px">
      <CardBody>
        <Stat pos="relative">
          <StatLabel>New customers</StatLabel>
          <StatHelpText pos="absolute" top="0" right="0">
            <StatArrow type="increase" /> {percentage}%
          </StatHelpText>

            mx="-4"

Customize colors

Use the colors prop to customize the chart colors. Supported formats are primary, purple, purple.400, or #4FD1C5.

Stacked

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

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


export default function Page() {

    <Card width="300px">
      <CardBody>
        <Stat pos="relative">
          <StatLabel>Customers</StatLabel>
          <StatNumber>{total ?? 0}</StatNumber>
          <Sparkline
            data={data}
