What is recharts?
Recharts is a composable charting library built on React components. It allows users to create various types of charts such as line, bar, area, pie, and more, using a declarative approach. It is easy to customize and extend, and it integrates well with the React ecosystem.
What are recharts's main functionalities?
LineChart
This code sample demonstrates how to create a simple LineChart with two lines, using the Recharts library. The chart includes a grid, axes, tooltips, and a legend.
{"import { LineChart, Line, XAxis, YAxis, CartesianGrid, Tooltip, Legend } from 'recharts';\nconst data = [{name: 'Page A', uv: 400, pv: 2400, amt: 2400}];\n<LineChart width={600} height={300} data={data}><CartesianGrid strokeDasharray=\"3 3\"/><XAxis dataKey=\"name\"/><YAxis/><Tooltip/><Legend /><Line type=\"monotone\" dataKey=\"pv\" stroke=\"#8884d8\" /><Line type=\"monotone\" dataKey=\"uv\" stroke=\"#82ca9d\" /></LineChart>"}
BarChart
This code sample shows how to create a BarChart with two bars per data point. It includes similar features to the LineChart, such as a grid, axes, tooltips, and a legend.
{"import { BarChart, Bar, XAxis, YAxis, CartesianGrid, Tooltip, Legend } from 'recharts';\nconst data = [{name: 'Page A', uv: 400, pv: 2400, amt: 2400}];\n<BarChart width={600} height={300} data={data}><CartesianGrid strokeDasharray=\"3 3\"/><XAxis dataKey=\"name\"/><YAxis/><Tooltip/><Legend /><Bar dataKey=\"pv\" fill=\"#8884d8\" /><Bar dataKey=\"uv\" fill=\"#82ca9d\" /></BarChart>"}
PieChart
This code sample illustrates how to create a PieChart. It includes a Pie component with labels, a Tooltip for additional information on hover, and a Legend.
{"import { PieChart, Pie, Tooltip, Legend } from 'recharts';\nconst data = [{name: 'Group A', value: 400}, {name: 'Group B', value: 300}];\n<PieChart width={800} height={400}><Pie dataKey=\"value\" isAnimationActive={false} data={data} cx={200} cy={200} outerRadius={80} fill=\"#8884d8\" label /><Tooltip/><Legend /></PieChart>"}
Other packages similar to recharts
chart.js
Chart.js is a popular canvas-based charting library that provides a wide range of chart types and is highly customizable. It is not React-specific and requires wrappers like 'react-chartjs-2' to integrate with React applications. Compared to Recharts, Chart.js may have better performance for complex animations and large datasets due to its canvas rendering.
victory
Victory is another React chart library that offers a set of composable components for building interactive data visualizations. It is similar to Recharts in its React-centric approach but differs in its API design and customization options. Victory is known for its flexibility and extensive customization capabilities.
highcharts-react-official
Highcharts is a comprehensive charting library that has been around for a long time. The 'highcharts-react-official' package is the official React wrapper for Highcharts. Highcharts offers a vast array of chart types and features, and it is known for its robustness and interactivity. However, it is not as tightly integrated with React as Recharts and may require a commercial license for certain uses.
Recharts
Introduction
Recharts is a Redefined chart library built with React and D3.
The main purpose of this library is to help you to write charts in React applications without any pain. Main principles of Recharts are:
- Simply deploy with React components.
- Native SVG support, lightweight depending only on some D3 submodules.
- Declarative components, components of charts are purely presentational.
Documentation at recharts.org and our storybook (WIP)
Please see the wiki for FAQ.
All development is done on the master
branch. The current latest release and storybook documentation reflects what is on the release
branch.
Examples
<LineChart width={400} height={400} data={data} margin={{ top: 5, right: 20, left: 10, bottom: 5 }}>
<XAxis dataKey="name" />
<Tooltip />
<CartesianGrid stroke="#f5f5f5" />
<Line type="monotone" dataKey="uv" stroke="#ff7300" yAxisId={0} />
<Line type="monotone" dataKey="pv" stroke="#387908" yAxisId={1} />
</LineChart>
All the components of Recharts are clearly separated. The lineChart is composed of x axis, tooltip, grid, and line items, and each of them is an independent React Component. The clear separation and composition of components is one of the principle Recharts follows.
Installation
npm
NPM is the easiest and fastest way to get started using Recharts. It is also the recommended installation method when building single-page applications (SPAs). It pairs nicely with a CommonJS module bundler such as Webpack.
$ npm install recharts
umd
The UMD build is also available on unpkg.com:
<script src="https://unpkg.com/react/umd/react.production.min.js"></script>
<script src="https://unpkg.com/react-dom/umd/react-dom.production.min.js"></script>
<script src="https://unpkg.com/recharts/umd/Recharts.min.js"></script>
Then you can find the library on window.Recharts
.
dev build
$ git clone https://github.com/recharts/recharts.git
$ cd recharts
$ npm install
$ npm run build
Demo
To examine the demos in your local build, execute:
$ npm run[-script] demo
and then browse to http://localhost:3000.
Storybook
We are in the process of unifying documentation and examples in storybook. To run it locally, execute
$ npm run[-script] storybook
and then browse to http://localhost:6006.
Releases
Releases are automated via GH Actions - when a new release is created in GH, CI will trigger that:
- Runs a build
- Runs tests
- Runs
npm publish
Version increments and tagging are not automated at this time.
Release testing
Until we can automate more, it should be preferred to test as close to the results of npm publish
as we possibly can. This ensures we don't publish unintended breaking changes. One way to do that is using yalc
- npm i -g yalc
.
- Make your changes in recharts
yalc publish
in rechartsyalc add recharts
in your test package (ex: in a vite or webpack reach app with recharts installed, imported, and your recent changes used)npm install
- Test a local run, a build, etc.
Module Formats
- babel-plugin-recharts A simple transform to cherry-pick Recharts modules so you don’t have to. Note: this plugin is out of date and may not work with 2.x

Thanks to Chromatic for providing the visual testing platform that helps us review UI changes and catch visual regressions.
