如何在vue-cli中引用使用echarts插件

下载 cnpm install echarts -S

在mian.js文件中引入

const ECharts =require('echarts')

Vue.prototype.$echarts = ECharts;

 

在chart.vue文件中使用

<template>
  <div>
      <div ref="chart" style=" 300px; height: 300px"></div>
  </div>
</template>

<script>

export default {
  mounted() {
    this.drawLine();
  },
  methods: {
    drawLine() {
      let mychart = this.$echarts.init(this.$refs.chart);
      mychart.setOption({
        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],
          },
        ],
      });
    },
  },
};
</script>

<style>
</style>
