Echarts

Echarts官网https://echarts.apache.org/zh/index.html
1.安装依赖：echarts
2.导入echarts
import echarts from 'echarts'
我这样导入出错了，后来直接require
3.为ECharts准备一个具备大小（宽高）的Dom
<div id="main" style="width: 750px; height: 400px"></div>
4. 基于准备好的dom，初始化echarts实例
这里我也直接let
let myChart = echarts.init(document.getElementById('main')); // var myChart = echarts.init(document.getElementById('main'))
5.指定图表的配置项和数据

var option = {
            title: {
                text: 'ECharts 入门示例'
            },
            tooltip: {},
            legend: {
                data:['销量']
            },
            xAxis: {
                data: ["衬衫","羊毛衫","雪纺衫","裤子","高跟鞋","袜子"]
            },
            yAxis: {},
            series: [{
                name: '销量',
                type: 'bar',
                data: [5, 20, 36, 10, 10, 20]
            }]
        };

    // 使用刚指定的配置项和数据显示图表。
    myChart.setOption(option);

init错误
vue写echarts 报错 Cannot read property ‘init‘ of undefined“

直接 let echarts = require('echarts');导入echarts，终于解决了，呜呜呜~
