概述
主题支持在文章中嵌入 ECharts 图表。
该功能由 vuepress-plugin-md-enhance 提供支持。
配置
主题默认不启用该功能。
你需要在你的项目中安装 ECharts 库。
pnpm
pnpm add echartsnpm
npm install echartsyarn
yarn add echarts然后在 .vuepress/config.ts 配置文件中，启用该功能：
.vuepress/config.ts
export default defineUserConfig({
theme: plumeTheme({
plugins: {
markdownEnhance: {
echarts: true,
},
}
})
})注

语法
JSON 配置
如果你可以很轻松的生成数据，你可以直接通过一个 JSON 代码块来提供 Echarts 配置:
::: echarts 标题
```json
{
// 此处为 ECharts 图表配置
}
```
:::JavaScript 配置
如果你需要通过脚本来获取数据，你可以使用 js 和 javascript 的代码块。
我们将通过 myChart 变量暴露 Echarts 实例，并且你应该将 Echart 配置赋值给 option 变量。 同时，你也可以赋值 width 和 height 来设置图表大小。
::: echarts Title
```js
const option = {
// 此处为 ECharts 图表配置
}
```
:::提示
你可以使用顶级 await 和 fetch 来从网络请求中获取数据。
相关配置，详见 ECharts 文档
高级
你可以在 客户端配置文件 中导入并使用 defineEchartsConfig 来自定义 Echarts:
import { defineClientConfig } from 'vuepress/client'
import { defineEchartsConfig } from 'vuepress-theme-plume/client'
defineEchartsConfig({
options: {
// 全局 Echarts 配置
},
setup: async () => {
// Echarts 设置
// 例如: await import("echarts-wordcloud")
},
})
export default defineClientConfig({
// ...
