[!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.
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
.

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

Props
-
init-options: object
Optional chart init configurations. See
echarts.init
'sopts
parameter here →Injection key:
INIT_OPTIONS_KEY
. -
theme: string | object
Theme to be applied. See
echarts.init
'stheme
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 thesetOption
method is called if theoption
object is modified directly and the reference remains unchanged; otherwise, if a new reference is bound tooption
,notMerge: true
will be specified. -
update-options: object
Options for updating chart option. See
echartsInstance.setOption
'sopts
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
'sopts
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 specifyingmanual-update
prop withtrue
and not providingoption
prop, the dataset won't be watched any more. After doing so, you need to retrieve the component instance withref
and manually callsetOption
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
→ -

-

-
zr:mouseup
-
zr:mousewheel
-

-

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 } } }

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.
