Uses Apache ECharts component for Vue.js

Vue-ECharts

Vue.js component for Apache ECharts.

Uses Apache ECharts 5 and works for both Vue.js 2/3.

Installation & Usage

npm & ESM

$ npm install echarts vue-echarts

To make vue-echarts work for Vue 2, you need to have @vue/composition-api installed:

npm i -D @vue/composition-api
Vue 3
import { createApp } from 'vue'
import ECharts from 'vue-echarts'
import { use } from "echarts/core"

// import ECharts modules manually to reduce bundle size
import {
  CanvasRenderer
} from 'echarts/renderers'
import {
  BarChart
} from 'echarts/charts'
import {
  GridComponent,
  TooltipComponent
} from 'echarts/components'

use([
  CanvasRenderer,
  BarChart,
  GridComponent,
  TooltipComponent
])

const app = createApp(...)

// register globally (or you can do it locally)
app.component('v-chart', ECharts)

app.mount(...)
Vue 2
import Vue from 'vue'
import ECharts from 'vue-echarts'
import { use } from 'echarts/core'

// import ECharts modules manually to reduce bundle size
import {
  CanvasRenderer
} from 'echarts/renderers'
import {
  BarChart
} from 'echarts/charts'
import {
  GridComponent,
  TooltipComponent
} from 'echarts/components'

use([
  CanvasRenderer,
  BarChart,
  GridComponent,
  TooltipComponent
]);

// register globally (or you can do it locally)
Vue.component('v-chart', ECharts)

new Vue(...)

We encourage manually importing components and charts from ECharts for smaller bundle size. See all supported renderers/charts/components here →

But if you really want to import the whole ECharts bundle without having to import modules manually, just add this in your code:

import "echarts";

CDN & Global variable

Drop <script> inside your HTML file and access the component via window.VueECharts.

Vue 3

<script src="https://cdn.jsdelivr.net/npm/vue@3.1.1"></script>
<script src="https://cdn.jsdelivr.net/npm/echarts@5.1.2"></script>
<script src="https://cdn.jsdelivr.net/npm/vue-echarts@6.0.0-rc.6"></script>


```js
const app = Vue.createApp(...)

// register globally (or you can do it locally)
app.component('v-chart', VueECharts)

Vue 2

<script src="https://cdn.jsdelivr.net/npm/vue@2.6.12"></script>
<script src="https://cdn.jsdelivr.net/npm/@vue/composition-api@1.0.0-rc.3"></script>
<script src="https://cdn.jsdelivr.net/npm/echarts@5.1.2"></script>

// register globally (or you can do it locally)
Vue.component("v-chart", VueECharts);

Props

  • init-options: object

    Optional chart init configurations. See echarts.init's opts parameter here →

    Injection key: INIT_OPTIONS_KEY.

  • theme: string | object

    Theme to be applied. See echarts.init's theme parameter here →

    Injection key: THEME_KEY.

  • option: object

    ECharts' universal interface. Modifying this prop will trigger ECharts' setOption method. Read more here →

  • update-options: object

    Options for updating chart option. See echartsInstance.setOption's opts parameter here →

    Injection key: UPDATE_OPTIONS_KEY.

  • group: string

    Group name to be used in chart connection. See echartsInstance.group here →

  • autoresize: boolean (default: false)

    Whether the chart should be resized automatically whenever its root is resized.

  • loading: boolean (default: false)

    Whether the chart is in loading state.

  • loading-options: object

    Configuration item of loading animation. See echartsInstance.showLoading's opts parameter here →

    Injection key: LOADING_OPTIONS_KEY.

  • manual-update: boolean (default: false)

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

Provide / Inject

Vue-ECharts provides provide/inject API for theme, init-options, update-options and loading-options to help configuring contextual options. eg. for init-options you can use the provide API like this:

Vue 3

import { INIT_OPTIONS_KEY } from 'vue-echarts'
import { provide } from 'vue'

// composition API
provide(INIT_OPTIONS_KEY, ...)

// options API
{
  provide: {
    [INIT_OPTIONS_KEY]: { ... }
  }
}

Vue 2

import { INIT_OPTIONS_KEY } from 'vue-echarts'

// in component options
{
  provide: {
    [INIT_OPTIONS_KEY]: { ... }
  }
}
