npm Build Status Coverage NPM downloads License ECharts Ver React Ver

Install

$ 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 git@github.com:hustcc/echarts-for-react.git

$ npm install

$ npm start

Then 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.

Usage

Code of a simple demo code showed below. For more example can see: https://git.hust.cc/echarts-for-react/

import React from 'react';
import ReactECharts from 'echarts-for-react';  // or var ReactECharts = require('echarts-for-react');

<ReactECharts
  option={this.getOption()}
  notMerge={true}
  lazyUpdate={true}
  theme={"theme_name"}
  onChartReady={this.onChartReadyCallback}
  onEvents={EventsDict}
  opts={}
/>

Import ECharts.js modules manually to reduce bundle size

With Echarts.js v5:

import React from 'react';
// import the core library.
import ReactEChartsCore from 'echarts-for-react/lib/core';
// Import the echarts core module, which provides the necessary interfaces for using echarts.
import * as echarts from 'echarts/core';
// Import charts, all with Chart suffix
import {
  // LineChart,
  BarChart,
  // PieChart,
  // ScatterChart,
  // RadarChart,
  // MapChart,
  // TreeChart,
  // TreemapChart,
  // GraphChart,
  // GaugeChart,
  // FunnelChart,
  // ParallelChart,
  // SankeyChart,
  // BoxplotChart,
  // CandlestickChart,
  // EffectScatterChart,
  // LinesChart,
  // HeatmapChart,
  // PictorialBarChart,
  // ThemeRiverChart,
  // SunburstChart,
  // CustomChart,
} from 'echarts/charts';
// import components, all suffixed with Component
import {
  // GridSimpleComponent,
  GridComponent,
  // PolarComponent,
  // RadarComponent,
  // GeoComponent,
  // SingleAxisComponent,
  // ParallelComponent,
  // CalendarComponent,
  // GraphicComponent,
  // ToolboxComponent,
  TooltipComponent,
  // AxisPointerComponent,
  // BrushComponent,
  TitleComponent,
  // TimelineComponent,
  // MarkPointComponent,
  // MarkLineComponent,
  // MarkAreaComponent,
  // LegendComponent,
  // LegendScrollComponent,
  // LegendPlainComponent,
  // DataZoomComponent,
  // DataZoomInsideComponent,
  // DataZoomSliderComponent,
  // VisualMapComponent,
  // VisualMapContinuousComponent,
  // VisualMapPiecewiseComponent,
  // AriaComponent,
  // TransformComponent,
  // DatasetComponent,
} from 'echarts/components';
// Import renderer, note that introducing the CanvasRenderer or SVGRenderer is a required step
import {
  CanvasRenderer,
  // SVGRenderer,
} from 'echarts/renderers';

// Register the required components
echarts.use(
  [TitleComponent, TooltipComponent, GridComponent, BarChart, CanvasRenderer]
);

// The usage of ReactEChartsCore are same with above.
<ReactEChartsCore
  echarts={echarts}
  option={this.getOption()}
  notMerge={true}
  lazyUpdate={true}
  theme={"theme_name"}
  onChartReady={this.onChartReadyCallback}
  onEvents={EventsDict}
  opts={}
/>

With Echarts.js v3 or v4:

import React from 'react';
// import the core library.
import ReactEChartsCore from 'echarts-for-react/lib/core';

// then import echarts modules those you have used manually.
import echarts from 'echarts/lib/echarts';
// import 'echarts/lib/chart/line';
import 'echarts/lib/chart/bar';
// import 'echarts/lib/chart/pie';
// import 'echarts/lib/chart/scatter';
// import 'echarts/lib/chart/radar';

// import 'echarts/lib/chart/map';
// import 'echarts/lib/chart/treemap';
// import 'echarts/lib/chart/graph';
// import 'echarts/lib/chart/gauge';
// import 'echarts/lib/chart/funnel';
// import 'echarts/lib/chart/parallel';
// import 'echarts/lib/chart/sankey';
// import 'echarts/lib/chart/boxplot';
// import 'echarts/lib/chart/candlestick';
// import 'echarts/lib/chart/effectScatter';
// import 'echarts/lib/chart/lines';
// import 'echarts/lib/chart/heatmap';

// import 'echarts/lib/component/graphic';
// import 'echarts/lib/component/grid';
// import 'echarts/lib/component/legend';
import 'echarts/lib/component/tooltip';
// import 'echarts/lib/component/polar';
// import 'echarts/lib/component/geo';
// import 'echarts/lib/component/parallel';
// import 'echarts/lib/component/singleAxis';
// import 'echarts/lib/component/brush';

import 'echarts/lib/component/title';

// import 'echarts/lib/component/dataZoom';
// import 'echarts/lib/component/visualMap';

// import 'echarts/lib/component/markPoint';
// import 'echarts/lib/component/markLine';
// import 'echarts/lib/component/markArea';

// import 'echarts/lib/component/timeline';
// import 'echarts/lib/component/toolbox';

// import 'zrender/lib/vml/vml';

// The usage of ReactEChartsCore are same with above.
<ReactEChartsCore
  echarts={echarts}
  option={this.getOption()}
  notMerge={true}
  lazyUpdate={true}
  theme={"theme_name"}
  onChartReady={this.onChartReadyCallback}
  onEvents={EventsDict}
  opts={}

Component API & Echarts API

the Component only has one API named getEchartsInstance.

  • getEchartsInstance() : get the echarts instance object, then you can use any API 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:

  1. binding / unbinding event.
  2. dynamic charts with dynamic data.
  3. get the echarts dom / dataURL / base64, save the chart to png.
  4. release the charts.
