React wrapper for ChartJs 2
Open for PR's and contributions!

Demo & Examples

Live demo: gor181.github.io/react-chartjs-2

To build the examples locally, run:

npm install
npm start

Then open localhost:8000 in a browser.

Installation via NPM

npm install react-chartjs-2 chart.js --save

Usage

Check example/src/components/* for usage.

import {Doughnut} from 'react-chartjs-2';

<Doughnut data={...} />

Properties

• data: PropTypes.object.isRequired,
• height: PropTypes.number,
• legend: PropTypes.object,
• onElementsClick: PropTypes.func,
• options: PropTypes.object,
• redraw: PropTypes.bool,
• width: PropTypes.number

Custom size

In order for Chart.js to obey the custom size you need to set maintainAspectRatio to false, example:

<Bar
	data={data}
	width={100}
	height={50}
	options={{
		maintainAspectRatio: false
	}}
/>

Chart instance

Chart instance can be accessed by placing a ref to the element as:

render() {
	componentDidMount() {
		console.log(this.refs.chart.chart_instance); // returns a Chart.js instance reference
	}
	return (
		<Doughnut ref='chart' data={data} />
	)
}

Events

onElementsClick (function)

A function to be called when mouse clicked on chart elememts, will return all element at that point as an array. Check

{
	onElementsClick: (elems) => {}
	// `elems` is an array of chartElements
}

Development (src, lib and the build process)

NOTE: The source code for the component is in src. A transpiled CommonJS version (generated with Babel) is available in lib for use with node.js, browserify and webpack. A UMD bundle is also built to dist, which can be included without the need for any build system.

To build, watch and serve the examples (which will also watch the component source), run npm start. If you just want to watch changes to src and rebuild lib, run npm run watch (this is useful if you are working with npm link).

Thanks
