ECharts
小于 1 分钟
让你 VuePress 站点中的 Markdown 文件支持图表。
配置
在你的项目中安装 ECharts:
pnpm
pnpm add -D echartsyarn
yarn add -D echartsnpm
npm i -D echarts之后启用它:
import { defineUserConfig } from "vuepress";
import { hopeTheme } from "vuepress-theme-hope";
export default defineUserConfig({
theme: hopeTheme({
markdown: {
echarts: true,
},
}),
});格式
使用 JSON
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
}
```
:::使用脚本
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。
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-plugin-md-enhance/client";
defineEChartsConfig({
options: {
// 全局 ECharts 配置
},
setup: async () => {
// ECharts 设置
// 例如: await import("echarts-wordcloud")
},
});
export default defineClientConfig({
// ...
});文档
