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: 'Jan 22',
value: 1557,
},
{
date: 'Jan 29',
value: 1977,
},
{

},
{
date: 'Jun 11',
value: 4096,
},
{
date: 'Jun 18',
value: 4193,
},
{
date: 'Jun 25',
value: 4759,
},

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>
<StatNumber>{data[data.length - 1].value ?? 0}</StatNumber>
<Sparkline
data={data}
categories={['value', 'compareValue']}
height="60px"
mx="-4"
/>
</Stat>
</CardBody>
</Card>
)
}
const data = [

Customize colors

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

import {

CardBody,
Stat,
StatLabel,
StatHelpText,
StatArrow,
StatNumber,

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>

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() {
const total =
data[data.length - 1].New +
data[data.length - 1].Active +
data[data.length - 1].Churned
return (
<Card width="300px">
<CardBody>
<Stat pos="relative">
<StatLabel>Customers</StatLabel>
<StatNumber>{total ?? 0}</StatNumber>
<Sparkline
data={data}
categories={['New', 'Active', 'Churned']}
colors={['green', 'blue', 'red']}
height="60px"
stack
/>
</Stat>
</CardBody>
</Card>
)
}
const data = [

New: 46,
