准备工作

安装echarts

 npm install echarts -S

全局引用

首先在main.js中引入echarts，将其绑定到vue原型上：

 import echarts from 'echarts'
 
 Vue.prototype.$echarts = echarts;

然后我们就可以在任何一个组件中使用echarts了！
接下来我们以封装一个echarts组件为例：

<template>
  <div>
    <div ref="chart"></div>
  </div>
</template>
<script>
  export default{
    data () {
      return {};
    },
    methods: {
      initCharts () {
        let myChart = this.$echarts.init(this.$refs.chart);
        // 绘制图表
        myChart.setOption({
            title: { text: '在Vue中使用echarts' },
            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]
            }]
        });
      }
    },
    mounted () {
      this.initCharts();
    }
  }
</script>

局部引用

局部引用代码会更加简洁，只在单个组件内使用即可：

 <template>
  <div>
    <div ref="chart"></div>
  </div>
</template>
<script>
  const echarts = require('echarts');
  export default{
    data () {
      return {};
    },
    methods: {
      initCharts () {
        let myChart = echarts.init(this.$refs.chart);
        // 绘制图表
        myChart.setOption({
            title: { text: '在Vue中使用echarts' },
            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]
            }]
        });
      }
    },
    mounted () {
      this.initCharts();
    }
  }
</script>
