Charts are an important part of any SaaS dashboard. They provide a quick insights into important and complex information and help users to understand the data better. The AreaChart and Sparkline have been available in Saas UI Pro for some time now, but today we're excited to release them fully Open Source, and together with 2 new chart types and improved APIs. These components are built on top of Recharts and are designed to build beautiful charts fast and with ease, while leaving enough room for customization.

Area Chart

The Area Chart is a great way to visualize data over time. It's especially useful when you want to visualize how data points change and form a pattern over a period. The Area Chart fills the area between the data line and the X-axis, making it easy to see fluctuations and trends.

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

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

const data = [
  {
    date: 'Dec 1',
    Backend: 40,
    Frontend: 21,

Line Chart

The Line Chart component is similar to the Area Chart but focuses solely on the data line, making it ideal for displaying data trends without the area fill. It's a great choice when you want to emphasize the actual data points' values.

import { Card, CardBody, CardHeader, Heading } from '@chakra-ui/react'
import { LineChart } 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>
        <LineChart
          data={data}
          categories={['Revenue']}
          valueFormatter={valueFormatter}
          yAxisWidth={80}
          height="300px"
        />
      </CardBody>
    </Card>
  )
}

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

    Revenue: 1981,

  {
    date: 'Feb 26',

    Revenue: 4193,
  },
  {
    date: 'Jun 25',
    Revenue: 4759,
  },
]

Bar Chart

If you need to compare different categories or data points, the Bar Chart component is an excellent choice. It displays data as horizontal or vertical bars, making it easy to visualize relative values and comparisons.

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">
          Customers
        </Heading>
      </CardHeader>
      <CardBody>
        <BarChart
          data={data}
          categories={['New', 'Active', 'Churned']}
          colors={['green', 'blue', 'red']}
          variant="solid"
          height="300px"
        />
      </CardBody>
    </Card>
  )
}

const data = [
  {
    date: 'Dec 1',
    New: 46,
    Active: 26,
    Churned: 2,
  },
  {
    date: 'Dec 2',

  {
    date: 'Dec 6',
    New: 61,
    Active: 34,
    Churned: 2,

Sparkline

The Sparkline component is a compact and minimalistic data visualization tool. It's great for displaying data trends within a limited space, like in a data table or a dashboard using the Chakra UI Stat component. Sparklines are typically used to show trends or changes over time quickly.

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']}
            colors={['orange', 'gray']}
            height="60px"
            mx="-4"
          />
        </Stat>
      </CardBody>
    </Card>
  )
}

const data = [
