[!IMPORTANT] We encourage manually importing components and charts from ECharts for smaller bundle size. We've built an import code generator to help you with that. You can just paste in your option code and we'll generate the precise import code for you.

Try it →

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

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

Vue 3 Demo →
<script src="https://cdn.jsdelivr.net/npm/vue@3.4.33"></script>
<script src="https://cdn.jsdelivr.net/npm/echarts@5.5.1"></script>
<script src="https://cdn.jsdelivr.net/npm/vue-echarts@7.0.3"></script>
const app = Vue.createApp(...)

// register globally (or you can do it locally)
app.component('v-chart', VueECharts)
Vue 2 Demo →
<script src="https://cdn.jsdelivr.net/npm/vue@2.7.16"></script>
<script src="https://cdn.jsdelivr.net/npm/echarts@5.5.1"></script>
<script src="https://cdn.jsdelivr.net/npm/vue-echarts@7.0.3"></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 →

    💡 When update-options is not specified, notMerge: false will be specified by default when the setOption method is called if the option object is modified directly and the reference remains unchanged; otherwise, if a new reference is bound to option, notMerge: true will be specified.

  • 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 | { throttle?: number, onResize?: () => void } (default: false)

    Whether the chart should be resized automatically whenever its root is resized. Use the options object to specify a custom throttle delay (in milliseconds) and/or an extra resize callback function.

  • 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.

Events

You can bind events with Vue's v-on directive.

<template>
  <v-chart :option="option" @highlight="handleHighlight" />
</template>

Note

Only the .once event modifier is supported as other modifiers are tightly coupled with the DOM event system.

Vue-ECharts support the following events:

  • highlight
  • downplay
  • selectchanged
  • legendselectchanged
  • legendselected
  • legendunselected
  • legendselectall
  • legendinverseselect
  • legendscroll
  • datazoom
  • datarangeselected
  • timelinechanged
  • timelineplaychanged
  • restore
  • dataviewchanged
  • magictypechanged
  • geoselectchanged
  • geoselected
  • geounselected
  • axisareaselected
  • brush
  • brushEnd
  • brushselected
  • globalcursortaken
  • rendered
  • finished
  • Mouse events
  • ZRender events
    • zr:click
    • zr:mousedown
    • zr:mouseup
    • zr:mousewheel
    • zr:dblclick
    • zr:contextmenu

See supported events here →

Native DOM Events

As Vue-ECharts binds events to the ECharts instance by default, there is some caveat when using native DOM events. You need to prefix the event name with native: to bind native DOM events (or you can use the .native modifier in Vue 2, which is dropped in Vue 3).

<template>
  <v-chart @native:click="handleClick" />
</template>

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

// composition API
provide(THEME_KEY, 'dark')

// options API
{
  provide: {
    [THEME_KEY]: 'dark'
  }
}
Vue 2
import { THEME_KEY } from 'vue-echarts'

// in component options
{
  provide: {
    [THEME_KEY]: 'dark'
  }
}

Note

You need to provide an object for Vue 2 if you want to change it dynamically.

// in component options
{
  data () {
    return {
      theme: { value: 'dark' }
    }
  },
  provide () {
    return {
      [THEME_KEY]: this.theme
    }
  }
}

Methods

  • setOption
  • getWidth
  • getHeight
  • getDom
  • getOption
  • resize
  • dispatchAction
  • convertToPixel
  • convertFromPixel
  • containPixel
  • showLoading
  • hideLoading
  • getDataURL
  • getConnectedDataURL
  • clear
  • dispose

Static Methods

Static methods can be accessed from echarts itself.

CSP: style-src or style-src-elem

If you are applying a CSP to prevent inline <style> injection, you need to use vue-echarts/csp instead of vue-echarts and include vue-echarts/csp/style.css manually.

Migration to v7

Read the breaking changes document in the release log and the migration shoud be straightforward.
