本文实例为大家分享了vue+echarts实现3D柱形图的具体代码，供大家参考，具体内容如下
1、安装echarts
npm install echarts --save2、引入echarts
import echarts from "echarts";
//修改原型链,可在全局使用
Vue.prototype.$echarts = echarts;3、创建图表 首先需要在 HTML 中创建图表的容器
<div id="echarts_park"></div>
//图表的容器必须指定宽高
#echarts_park {
width: 400px;
height: 200px;
}4、渲染图表
mounted() {
this.drawPark();
},
methods: {
drawPark() {
//初始化echarts
let myChart = this.$echarts.init(document.getElementById("echarts_park"));
let num= [
"12",
"12",
