ECharts component for Vue.js.

🇨🇳 中文版

Built upon ECharts v4.1.0+ and depends on Vue.js v2.2.6+.


npm (Recommended)

$ npm install echarts vue-echarts


Include echarts and vue-echarts in your HTML file like this:

<script src=""></script>
<script src=""></script>


ES Modules with npm & Vue Loader (Recommended)

import Vue from 'vue'
import ECharts from 'vue-echarts' // refers to components/ECharts.vue in webpack

// import ECharts modules manually to reduce bundle size
import 'echarts/lib/chart/bar'
import 'echarts/lib/component/tooltip'

// If you want to use ECharts extensions, just import the extension package, and it will work
// Taking ECharts-GL as an example:
// You only need to install the package with `npm install --save echarts-gl` and import it as follows
import 'echarts-gl'

// register component to use
Vue.component('v-chart', ECharts)

⚠️ Heads up

Importing the source version

Vue-ECharts offers an untranspiled version for webpack by default. If you are using official Vue CLI to create your project, you may encounter the problem that the default configuration will exclude node_modules from files to be transpiled by Babel. You need to modify the configuration as follows:

For Vue CLI 3+, add vue-echarts and resize-detector into transpileDependencies in vue.config.js like this:

// vue.config.js
module.exports = {
  transpileDependencies: [

For Vue CLI 2 with the webpack template, modify build/webpack.base.conf.js like this:

        test: /\.js$/,
        loader: 'babel-loader',
-       include: [resolve('src'), resolve('test')]
+       include: [
+         resolve('src'),
+         resolve('test'),
+         resolve('node_modules/vue-echarts'),
+         resolve('node_modules/resize-detector')
+       ]

If you are using bare webpack config, just do similar modifications to make it work.

Using with Nuxt.js

When using Vue-ECharts on the server-side with Nuxt.js, it may not be properly transpiled because Nuxt.js prevents files under node_modules from being bundled into the server bundle with only a few exceptions by default. We need to whitelist vue-echarts manually.

For Nuxt.js v2, modify nuxt.config.js as follows:

module.exports = {
  build: {
    transpile: ['vue-echarts', 'resize-detector']

For Nuxt.js v1, modify nuxt.config.js as follows:

// Don't forget to
// npm i --save-dev webpack-node-externals
const nodeExternals = require('webpack-node-externals')

module.exports = {
  // ...
  build: {
    extend (config, { isServer }) {
      // ...
      if (isServer) {
        config.externals = [
            // default value for `whitelist` is
            // [/es6-promise|\.(?!(?:js|json)$).{1,5}$/i]
            whitelist: [/es6-promise|\.(?!(?:js|json)$).{1,5}$/i, /^vue-echarts/]


  paths: {
    'vue': 'path/to/vue',
    'echarts': 'path/to/echarts',
    'vue-echarts': 'path/to/vue-echarts'

require(['vue', 'vue-echarts'], function (Vue, ECharts) {
  // register component to use...
  Vue.component('v-chart', ECharts)

Global variable

Without any module system, the component is exposed as window.VueECharts.

// register component to use
Vue.component('v-chart', VueECharts)

Using the component

<v-chart :options="polar"/>

 * The default size is 600px×400px, for responsive charts
 * you may need to set percentage values as follows (also
 * don't forget to provide a size for the container).
.echarts {
  width: 100%;
  height: 100%;

import ECharts from 'vue-echarts'
import 'echarts/lib/chart/line'
import 'echarts/lib/component/polar'

export default {
  components: {
    'v-chart': ECharts
  data () {
    let data = []

    for (let i = 0; i <= 360; i++) {
        let t = i / 180 * Math.PI
        let r = Math.sin(2 * t) * Math.cos(2 * t)
        data.push([r, i])

    return {
      polar: {
        title: {
          text: '极坐标双数值轴'
        legend: {
          data: ['line']
        polar: {
          center: ['50%', '54%']
        tooltip: {
          trigger: 'axis',
          axisPointer: {
            type: 'cross'
        angleAxis: {
          type: 'value',
          startAngle: 0
        radiusAxis: {
          min: 0
        series: [
            coordinateSystem: 'polar',
            name: 'line',
            type: 'line',
            showSymbol: false,
            data: data
        animationDuration: 2000

Props (all reactive)

  • initOptions

    Used to initialize ECharts instance.

  • theme

    The theme used for current ECharts instance.

  • options

    Used to update data for ECharts instance. Modifying this prop will trigger ECharts' setOption method.

    If you mutate the data bound to options while retaining the object reference, setOption will be called with notMerge: false. Otherwise, if you bind a new object to options, setOption will be called with notMerge: true.

    For example, if we have the following template:

    <v-chart :options="data"/>

    Then: = newObject // setOption(this.options, true) = 'Trends' // setOption(this.options, false)
  • group

    This prop is automatically bound to the same prop of the ECharts instance.

  • autoresize (default: false)

    This prop indicates ECharts instance should be resized automatically whenever its root is resized.

  • manual-update (default: false)

    For critical performance scenarios (having a large dataset) we'd better bypass Vue's reactivity system for options prop. By specifying manual-update prop with true and not providing options prop, the dataset won't be watched anymore. After doing so, you need to retrieve the component instance with ref and manually call mergeOptions method to update the chart.


  • width [readonly]

    Used to retrieve the current width of the ECharts instance.

  • height [readonly]

    Used to retrieve the current height of the ECharts instance.

  • computedOptions [readonly]

    Used to retrieve the actual options calculated by ECharts after updating options.


  • mergeOptions (use setOption in ECharts under the hood)

    Provides a better method name to describe the actual behavior of setOption.

  • appendData

  • resize

  • dispatchAction

  • showLoading

  • hideLoading

  • convertToPixel

  • convertFromPixel

  • containPixel

  • getDataURL

  • getConnectedDataURL

  • clear

  • dispose
