The simplest, and the best React wrapper for Apache ECharts.
$ npm install --save echarts-for-react
# `echarts` is the peerDependence of `echarts-for-react`, you can install echarts with your own version.
$ npm install --save echarts
Then use it.
import ReactECharts from 'echarts-for-react';
// render echarts option.
<ReactECharts option={this.getOption()} />You can run website.
$ git clone [email protected]:hustcc/echarts-for-react.git
$ npm install
$ npm startThen open http://127.0.0.1:8081/ in your browser. or see https://git.hust.cc/echarts-for-react/ which is deploy on gh-pages.
Code of a simple demo code showed below. For more example can see: https://git.hust.cc/echarts-for-react/

// next.config.js
const withTM = require("next-transpile-modules")(["echarts", "zrender"]);
module.exports = withTM({})option(required, object)
the echarts option config, can see https://echarts.apache.org/option.html#title.

});
...
// render the echarts use option `theme`
<ReactECharts
option={this.getOption()}
style={{height: '300px', width: '100%'}}
className='echarts-for-echarts'
theme='my_theme' />onChartReady(optional, function)
when the chart is ready, will callback the function with the echarts object as it's paramter.
loadingOption(optional, object)
the echarts loading option config, can see https://echarts.apache.org/api.html#echartsInstance.showLoading.
showLoading(optional, bool, default: false)
bool, when the chart is rendering, show the loading mask.
onEvents(optional, array(string=>function) )
binding the echarts event, will callback with the echarts event object, and the echart object as it's paramters. e.g:
const onEvents = {
'click': this.onChartClick,
'legendselectchanged': this.onChartLegendselectchanged
}
...
<ReactECharts
option={this.getOption()}
style={{ height: '300px', width: '100%' }}
onEvents={onEvents}
/>for more event key name, see: https://echarts.apache.org/api.html#events
opts(optional, object)
the opts of echarts. object, will be used when initial echarts instance by echarts.init. Document here.
<ReactECharts
option={this.getOption()}
style={{ height: '300px' }}
opts={{renderer: 'svg'}} // use svg to render the chart.
/>autoResize(optional, boolean)
decide whether to trigger this.resize when window resize. default is true.
the Component only has one API named getEchartsInstance.
getEchartsInstance(): get the echarts instance object, then you can use anyAPI of echarts.
for example:
// render the echarts component below with rel
<ReactECharts
ref={(e) => { this.echartRef = e; }}
option={this.getOption()}
/>
// then get the `ReactECharts` use this.echarts_react
const echartInstance = this.echartRef.getEchartsInstance();
// then you can use any API of echarts.
const base64 = echartInstance.getDataURL();About API of echarts, can see https://echarts.apache.org/api.html#echartsInstance.
You can use the API to do:
binding / unbindingevent.dynamic chartswith dynamic data.- get the echarts dom / dataURL / base64, save the chart to png.
releasethe charts.
Use the props opts of component with renderer = 'svg'. For example:
<ReactECharts
option={this.getOption()}
style={{height: '300px'}}
opts={{renderer: 'svg'}} // use svg to render the chart.
/>Install and import echarts-gl module when you want to create a GL instance
npm install --save echarts-glimport 'echarts-gl'
