Vue中使用Echarts的两种方式

【1】方法1：require引入js文件，注意路径问题

let echarts=require('../../../static/js/echarts4.0.4.min.js');

【2】echart代码

 drawScatterChart: function() {
            let scatterChart = echarts.init(document.querySelector('.results53-echart'));
            let textStyle2 = {
                color: '#888',
                fontStyle: 'normal',
                fontWeight: 'normal',
                fontFamily: 'sans-serif',
                fontSize: 14,
            };
            let textStyle = {
                color: 'white',
                fontStyle: 'normal',
                fontWeight: 'normal',
                fontFamily: 'sans-serif',
                fontSize: 14,
            };
            let scatterChart_option = {

【3】实现效果

【4】方法2：npm install echarts -S 安装echarts
 

(1)npm install echarts -S 安装

(2)在main.js里面添加，将echarts设置为全局变量
   import echarts from 'echarts'
   Vue.prototype.$echarts = echarts

(3)vue中使用echarts
   let scatterChart = this.$echarts.init(document.querySelector('.res-echart')); 

这两种方式都可达到目的
