1.vue项目中使用eCharts

  1. 安装echarts依赖 npm i echarts -S
  2. main.js中全局引入,并注册到原型上
import * as echarts from 'echarts'
Vue.prototype.$echarts = echarts
  1. 在组件中使用
<template>
  <div>
    <div
      id="main"
      style="width: 600px;height:400px;"
    ></div>
  </div>
</template>
<script>
export default {
  name: "App",
  methods: {
    drawChart() {
      // 基于准备好的dom,初始化echarts实例
      let myChart = this.$echarts.init(document.getElementById("main"));
      // 指定图表的配置项和数据
      let 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);
    }
  },
  mounted() {
    this.drawChart();
  }
};
</script>
