vue-echarts + vue3 立体柱形图

如图：

需要结合vue-echarts、echarts完成。vue-echarts官网
我这里遇到一个问题，npm vue-echarts一直失败.解决方法：npm指定下载版本号，我是下载的：

npm i vue-echarts@^6.0.0-rc.4

main.js：

import { createApp } from 'vue'
import App from './App.vue'

import ECharts from 'vue-echarts';
import { graphic } from 'echarts/index';

const app = createApp(App)
app.provide('graphic', graphic);
app.component('VChart', ECharts);
app.mount('#app')

vue文件：

    <div>
        <v-chart class="chart" :option="option" />
