1. 安装

npm install echarts --save

 

package.json中有此项，代表安装成功

2. 引入全部组件

如果你项目里需要用到各种各样的图表，建议使用本条。

• main.js 中引入

 // 引入echarts
import echarts from 'echarts'
Vue.prototype.$echarts = echarts

• 使用 

export default {
  name: 'hello',
  data () {
    return {
      msg: 'Welcome to Your Vue.js App'
    }
  },
  mounted(){
    this.drawLine();
  },
  methods: {
    drawLine(){
        // 基于准备好的dom，初始化echarts实例
        let myChart = this.$echarts.init(document.getElementById('myChart'))
        // 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: 'demo',
                data: [5, 20, 36, 10, 10, 20]
            }]
        });
    }
  }
}

3. 按需引入（项目中少量图表的情况下，采用此条）

// 引入基本模板
let echarts = require("echarts/lib/echarts");
// 引入柱状图组件
require("echarts/lib/chart/bar");
// 引入提示框和title组件
require("echarts/lib/component/tooltip");
require("echarts/lib/component/title");
// 不引入这个会报错 xAxis "0" not found
require("echarts/lib/component/grid");

4. 封装成组件(echarts.vue)

<template>
  <div>
    <div :style="{ height: height, width: width }" :id="id"></div>
  </div>
</template>
<script>
// 引入基本模板
let echarts = require("echarts/lib/echarts");
// 引入柱状图组件
require("echarts/lib/chart/bar");
// 引入提示框和title组件
require("echarts/lib/component/tooltip");
require("echarts/lib/component/title");
// 不引入这个会报错 xAxis "0" not found
require("echarts/lib/component/grid");
// import 'echarts/lib/component/grid';
export default {
  name: "echarts",
  props: {
    height: {
      type: String,
      default: "500px",
    },
    width: {
      type: String,
      default: "500px",
    },
    id: {
      type: String,
      default: "demo",
    },
  },
  data() {
    return {};
  },
  mounted() {
    this.drawLine();
  },
  methods: {
    drawLine() {
      // 基于准备好的dom，初始化echarts实例
      console.log(this.id);
      let myChart = echarts.init(document.getElementById(this.id));
      // 绘制图表
      myChart.setOption({
        title: { text: "在Vue中使用echarts" },
        tooltip: {},
        xAxis: {
            type: 'category',
            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>

效果图如上（第二条） 

5. 使用此组件 

<template>
   <div class="main-con">
     <echarts
     :width="width"
     :height="height"
     :id="id"></echarts>
   </div>
</template>
<script>
import echarts from './echarts.vue'
export default {
  name: 'chartShow',
  data(){
    return{
      width: '100%',
      height: '500px',
      id: 'chartShow'
    }
  },
  components:{
    echarts
  }
}
</script>
<style lang="scss" scoped>
.main-con{
  width: 100%;
  height: 100%;
  padding: 20px;
}
</style>

 无论是按需引入，还是全局引入，都建议采用封装组件的方式，纵享丝滑，方便的一批~
