If you are migrating from vue-echarts ≤ 5, you should read the Migration to v6 section before you update to v6.

npm install echarts vue-echarts

To make vue-echarts work for Vue 2 (<2.7.0), you need to have @vue/composition-api installed:

npm i @vue/composition-api

If you are using NuxtJS on top of Vue 2, you'll also need @nuxtjs/composition-api:

npm i @nuxtjs/composition-api

And then add '@nuxtjs/composition-api/module' in the buildModules option in your nuxt.config.js.

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";

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

<script src="https://cdn.jsdelivr.net/npm/[email protected]"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]"></script>

const app = Vue.createApp(...)

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

<script src="https://cdn.jsdelivr.net/npm/[email protected]"></script>

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

See more examples here.

• 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.

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:

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

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

// options API
{
  provide: {
    [THEME_KEY]: 'dark'
  }
}

import { THEME_KEY } from 'vue-echarts'

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

Static methods can be accessed from echarts itself.

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 →

• Mouse events
  • click →
  • dblclick →

• ZRender events
  • zr:click
  • zr:mousedown
  • zr:mouseup
  • zr:mousewheel
  • zr:dblclick
  • zr:contextmenu

If you are applying a CSP to prevent inline <style> injection, you need to use files from dist/csp directory and include dist/csp/style.css into your app manually.

💡 Please make sure to read the migration guide for ECharts 5 as well.

The following breaking changes are introduced in vue-echarts@6:

• If you are using version prior to [email protected], @vue/composition-api is required to be installed to use Vue-ECharts with Vue 2.

• options is renamed to option to align with ECharts itself.
• Updating option will respect update-options configs instead of checking reference change.
• watch-shallow is removed. Use manual-update for performance critical scenarios.

• mergeOptions is renamed to setOption to align with ECharts itself.
• showLoading and hideLoading is removed. Use the loading and loading-options props instead.
• appendData is removed. (Due to ECharts 5's breaking change.)
• All static methods are removed from vue-echarts. Use those methods from echarts directly.

• Computed getters (width, height, isDisposed and computedOptions) are removed. Use the getWidth, getHeight, isDisposed and getOption methods instead.

• Now the root element of the component have 100%×100% size by default, instead of 600×400.
