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：

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

<script setup>

    // 会canvas的应该都能看得懂，shape是从custom传入的
    const { xAxisPoint } = shape;
    // console.log(shape)
    const c0 = [shape.x + 17, shape.y];
    const c1 = [shape.x - 15, shape.y];
    const c2 = [xAxisPoint[0] - 15, xAxisPoint[1]];
    const c3 = [xAxisPoint[0] + 17, xAxisPoint[1]];

      .lineTo(c2[0], c2[1])
