这篇文章主要介绍了vue+echarts怎么实现3D柱形图的相关知识，内容详细易懂，操作简单快捷，具有一定借鉴价值，相信大家阅读完这篇vue+echarts怎么实现3D柱形图文章都会有所收获，下面我们一起来看看吧。

效果如下：

1、安装echarts

npm install echarts --save

2、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"));
