vue项目开发如何引入echarts图表

npm install echarts -S

import echarts from 'echarts'

Vue.prototype.$echarts = echarts

<div id="bar" style="width: 300px; height: 300px;"></div>

getBar() {
  let myChart = this.$echarts.init(document.getElementById("bar"));
  // 配置参数
  let config = {
    title: { text: "柱状图" },
    tooltip: {},
    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],
      },
    ],
  };
  // 设置参数
  myChart.setOption(config);
},
