React Chartkick

Create beautiful JavaScript charts with one line of React

See it in action

Supports Chart.js, Google Charts, and Highcharts

Quick Start

Run

npm install react-chartkick chart.js

And add

import { LineChart, PieChart } from 'react-chartkick'
import 'chartkick/chart.js'

This sets up Chartkick with Chart.js. For other charting libraries, see detailed instructions.

Charts

Line chart

<LineChart data={{"2021-01-01": 11, "2021-01-02": 6}} />

Pie chart

<PieChart data={[["Blueberry", 44], ["Strawberry", 23]]} />

Column chart

<ColumnChart data={[["Sun", 32], ["Mon", 46], ["Tue", 28]]} />

Bar chart

<BarChart data={[["Work", 32], ["Play", 1492]]} />

Area chart

<AreaChart data={{"2021-01-01": 11, "2021-01-02": 6}} />

Scatter chart

<ScatterChart data={[[174.0, 80.0], [176.5, 82.3]]} xtitle="Size" ytitle="Population" />

Geo chart - Google Charts

<GeoChart data={[["United States", 44], ["Germany", 23], ["Brazil", 22]]} />

Timeline - Google Charts

<Timeline data={[["Washington", "1789-04-29", "1797-03-03"], ["Adams", "1797-03-03", "1801-03-03"]]} />

Multiple series

data = [
  {name: "Workout", data: {"2021-01-01": 3, "2021-01-02": 4}},
  {name: "Call parents", data: {"2021-01-01": 5, "2021-01-02": 3}}
];

and

<LineChart data={data} />

Data

Data can be an array, object, callback, or URL.

Array

<LineChart data={[["2021-01-01", 2], ["2021-01-02", 3]]} />

Object

<LineChart data={{"2021-01-01": 2, "2021-01-02": 3}} />

Callback

function fetchData(success, fail) {
  success({"2021-01-01": 2, "2021-01-02": 3})
  // or fail("Data not available")
}

and

<LineChart data={fetchData} />

URL

Make your pages load super fast and stop worrying about timeouts. Give each chart its own endpoint.

<LineChart data="/stocks" />

Options

Id, width, and height

<LineChart id="users-chart" width="800px" height="500px" />

Min and max values

<LineChart min={1000} max={5000} />

min defaults to 0 for charts with non-negative values. Use null to let the charting library decide.

Min and max for x-axis - Chart.js

<LineChart xmin="2021-01-01" xmax="2022-01-01" />

Colors

<LineChart colors={["#b00", "#666"]} />

Stacked columns or bars

<ColumnChart stacked={true} />

Discrete axis

<LineChart discrete={true} />

Label (for single series)

<LineChart label="Value" />

Axis titles

<LineChart xtitle="Time" ytitle="Population" />

Straight lines between points instead of a curve

<LineChart curve={false} />

Show or hide legend

<LineChart legend={true} />

Specify legend position

<LineChart legend="bottom" />

Donut chart

<PieChart donut={true} />

Prefix, useful for currency - Chart.js, Highcharts

<LineChart prefix="$" />

Suffix, useful for percentages - Chart.js, Highcharts

<LineChart suffix="%" />

Set a thousands separator - Chart.js, Highcharts

<LineChart thousands="," />

Set a decimal separator - Chart.js, Highcharts

<LineChart decimal="," />

Set significant digits - Chart.js, Highcharts

<LineChart precision={3} />

Set rounding - Chart.js, Highcharts

<LineChart round={2} />

Show insignificant zeros, useful for currency - Chart.js, Highcharts

<LineChart round={2} zeros={true} />

Friendly byte sizes - Chart.js

<LineChart bytes={true} />

Specify the message when the chart is loading

<LineChart loading="Loading..." />

Specify the message when data is empty

<LineChart empty="No data" />

Refresh data from a remote source every n seconds

<LineChart refresh={60} />

You can pass options directly to the charting library with:

<LineChart library={{backgroundColor: "#eee"}} />

See the documentation for Google Charts, Highcharts, and Chart.js for more info.

To customize datasets in Chart.js, use:

<LineChart dataset={{borderWidth: 10}} />

You can pass this option to individual series as well.

Global Options

To set options for all of your charts, use:

Chartkick.options = {
  colors: ["#b00", "#666"]
}

Multiple Series

You can pass a few options with a series:

  • name
  • data
  • color
  • dataset - Chart.js only
  • points - Chart.js only
  • curve - Chart.js only

Download Charts

Chart.js only

Give users the ability to download charts. It all happens in the browser - no server-side code needed.

<LineChart download={true} />

Set the filename

<LineChart download="boom" />

Note: Safari will open the image in a new window instead of downloading.

Set the background color

<LineChart download={{background: "#fff"}} />

Installation

Chart.js

Run

npm install react-chartkick chart.js

And add

import { LineChart, PieChart } from 'react-chartkick'
import 'chartkick/chart.js'

Google Charts

Run

npm install react-chartkick

And add

import Chartkick, { LineChart, PieChart } from 'react-chartkick'

And include on the page

<script src="https://www.gstatic.com/charts/loader.js"></script>

To specify a language or Google Maps API key, use:

Chartkick.configure({language: "de", mapsApiKey: "..."})

Highcharts

Run

npm install react-chartkick highcharts

And add

import { LineChart, PieChart } from 'react-chartkick'
import 'chartkick/highcharts'

No Package Manager

Include the charting library and the Chartkick library

<script src="https://unpkg.com/chart.js@4.2.0/dist/chart.umd.js"></script>
<script src="https://unpkg.com/chartjs-adapter-date-fns@3.0.0/dist/chartjs-adapter-date-fns.bundle.js"></script>
<script src="https://unpkg.com/chartkick@5.0.0"></script>
<script src="https://unpkg.com/react-chartkick@0.5.3"></script>

Charts are prefixed with ReactChartkick, like ReactChartkick.LineChart.

Multiple Libraries

If more than one charting library is loaded, choose between them with:

<LineChart adapter="google" />

Options are google, highcharts, and chartjs

Upgrading

0.5.0

For the no package manager install, Chartkick.js is no longer bundled, allowing you to update them independently. Include it manually before React Chartkick.

<script src="https://unpkg.com/chartkick@4.0.2"></script>
