Vue-ECharts
Vue.js (v2/v3) component for Apache ECharts™ (v5).
[!IMPORTANT] We have released an import code generator that can generate precise import code by pasting the
optioncode.
💡 Heads up 💡 
If you are migrating from vue-echarts ≤ 5, you should read the Migration to v6 section before you update to v6.

Installation & Usage
npm & ESM
npm i echarts vue-echarts
To make vue-echarts work for Vue 2 (<2.7.0), you need to have @vue/composition-api installed (@vue/runtime-core for TypeScript support):
npm i @vue/composition-api
npm i @vue/runtime-core # for TypeScript support
If you are using NuxtJS on top of Vue 2, you'll 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.

[!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
optioncode and we'll generate the precise import code for you.
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 Demo →
<script src="https://cdn.jsdelivr.net/npm/vue@3.4.23"></script>
<script src="https://cdn.jsdelivr.net/npm/echarts@5.4.3"></script>
<script src="https://cdn.jsdelivr.net/npm/vue-echarts@6.7.3"></script>
const app = Vue.createApp(...)
// register globally (or you can do it locally)
app.component('v-chart', VueECharts)
Vue 2 Demo →

Props
-
init-options: objectOptional chart init configurations. See
echarts.init'soptsparameter here →Injection key:
INIT_OPTIONS_KEY. -
theme: string | objectTheme to be applied. See
echarts.init'sthemeparameter here →Injection key:
THEME_KEY. -
option: objectECharts' universal interface. Modifying this prop will trigger ECharts'
setOptionmethod. Read more here →💡 When
update-optionsis not specified,notMerge: falsewill be specified by default when thesetOptionmethod is called if theoptionobject is modified directly and the reference remains unchanged; otherwise, if a new reference is bound tooption,notMerge: truewill be specified. -
update-options: objectOptions for updating chart option. See
echartsInstance.setOption'soptsparameter here →Injection key:
UPDATE_OPTIONS_KEY. -
group: stringGroup name to be used in chart connection. See
echartsInstance.grouphere → -
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: objectConfiguration item of loading animation. See
echartsInstance.showLoading'soptsparameter 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
optionprop. By specifyingmanual-updateprop withtrueand not providingoptionprop, the dataset won't be watched any more. After doing so, you need to retrieve the component instance withrefand manually callsetOptionmethod 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
.onceevent 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:clickzr:mousedownzr:mouseupzr:mousewheelzr:dblclickzr: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 files from dist/csp directory and include dist/csp/style.css into your app manually.
Migration to v6
💡 Please make sure to read the migration guide for ECharts 5 as well.
The following breaking changes are introduced in vue-echarts@6:
Vue 2 support
- If you are using version prior to
vue@2.7.0,@vue/composition-apiis required to be installed to use Vue-ECharts with Vue 2 (and also@vue/runtime-corefor TypeScript support).
Props
optionsis renamed tooptionto align with ECharts itself.- Updating
optionwill respectupdate-optionsconfigs instead of checking reference change. watch-shallowis removed. Usemanual-updatefor performance critical scenarios.
Methods
mergeOptionsis renamed tosetOptionto align with ECharts itself.showLoadingandhideLoadingis removed. Use theloadingandloading-optionsprops instead.appendDatais removed. (Due to ECharts 5's breaking change.)- All static methods are removed from
vue-echarts. Use those methods fromechartsdirectly.
Computed getters
- Computed getters (
width,height,isDisposedandcomputedOptions) are removed. Use thegetWidth,getHeight,isDisposedandgetOptionmethods instead.
Styles
- Now the root element of the component have
100%×100%size by default, instead of600×400.
