> [!IMPORTANT]

> We encourage manually importing components and charts from ECharts for smaller bundle size. We've built an [import code generator](https://vue-echarts.dev/#codegen) 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 →](https://vue-echarts.dev/#codegen)



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



```js

import "echarts";

```



### CDN



Drop `` inside your HTML file and access the component via `window.VueECharts`.



<details>

<summary>Vue 3 <a href="https://stackblitz.com/edit/vue-echarts-vue-3-global?file=index.html">Demo →</a></summary>



<!-- vue3Scripts:start -->

```html

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



```



```js

const app = Vue.createApp(...)



// register globally (or you can do it locally)

app.component('v-chart', VueECharts)

```



Vue 2 Demo →



```html



```



```js

// register globally (or you can do it locally)

Vue.component("v-chart", VueECharts);

```



See more examples [here](https://github.com/ecomfe/vue-echarts/tree/main/src/demo).



### Props



- `init-options: object`



  Optional chart init configurations. See `echarts.init`'s `opts` parameter [here →](https://echarts.apache.org/en/api.html#echarts.init)



  Injection key: `INIT_OPTIONS_KEY`.



- `theme: string | object`



  Theme to be applied. See `echarts.init`'s `theme` parameter [here →](https://echarts.apache.org/en/api.html#echarts.init)



  Injection key: `THEME_KEY`.



- `option: object`



  ECharts' universal interface. Modifying this prop will trigger ECharts' `setOption` method. Read more [here →](https://echarts.apache.org/en/option.html)



  > 💡 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 →](https://echarts.apache.org/en/api.html#echartsInstance.setOption)



  Injection key: `UPDATE_OPTIONS_KEY`.



- `group: string`



  Group name to be used in chart [connection](https://echarts.apache.org/en/api.html#echarts.connect). See `echartsInstance.group` [here →](https://echarts.apache.org/en/api.html#echartsInstance.group)



- `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 →](https://echarts.apache.org/en/api.html#echartsInstance.showLoading)



  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.



```vue



  



```



> **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:

See supported events [here →](https://echarts.apache.org/en/api.html#events)



#### 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).



```vue



  



```



### 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



```js

import { THEME_KEY } from 'vue-echarts'

import { provide } from 'vue'



// composition API

provide(THEME_KEY, 'dark')



// options API

{

  provide: {

    [THEME_KEY]: 'dark'

  }

}

```



Vue 2



```js

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.

>

> ```js

> // in component options

> {

>   data () {

>     return {

>       theme: { value: 'dark' }

>     }

>   },

>   provide () {

>     return {

>       [THEME_KEY]: this.theme

>     }

>   }

> }

> ```

### Static Methods



Static methods can be accessed from [`echarts` itself](https://echarts.apache.org/en/api.html#echarts).



## CSP: `style-src` or `style-src-elem`



If you are applying a CSP to prevent inline `` 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](https://github.com/ecomfe/vue-echarts/releases/tag/v7.0.0-beta.0) and the migration shoud be straightforward.



## Local development



```sh

pnpm i

pnpm serve

```



Open `http://localhost:8080` to see the demo.
