代码与实例

过程

首先下载echarts
 

cnpm install echarts -S
//或者是
cnpm install echarts --save

下载好后：

在main.js中导入：

import echarts from 'echarts'
Vue.prototype.$axios=Axios

在vue中实例下：

<template>
  <div>
    <div>
      <div id="main" style="width: 500px; height:500px"></div>
    </div>
  </div>
</template>

script如下：

<script>
export default {

  mounted(){
    this.drawLine();
  },
  methods: {
    handleSubmit(){
        ...
        ...
        ...
    },

    //开始画图了
    drawLine(){

      // 基于准备好的dom，初始化echarts实例
      //var myChart = this.$echarts.init(document.getElementById('main'));
      let myChart = this.$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);

    }
  }
}
</script>

程序运行截图如下：

 

 

代码与实例

结构如下：

源码如下：

main.js

// The Vue build version to load with the `import` command
// (runtime-only or standalone) has been set in webpack.base.conf with an alias.
import Vue from 'vue'
import Axios from 'axios'
import echarts from 'echarts'
import TestEChart from './TestEChart'

Vue.config.productionTip = false
Vue.prototype.$axios=Axios
Vue.prototype.$echarts = echarts

/* eslint-disable no-new */
new Vue({
  el: '#app',
  components: { TestEChart },
  template: '<TestEChart/>',
})

TestEChart.vue

<template>
  <div>
    <div>
      <div id="main" style="width: 500px; height:500px"></div>
    </div>
    <div>
      <button @click="handleSubmit">获取</button>
    </div>
  </div>
</template>

<script>
export default {

  mounted(){
    this.drawLine();
  },
  methods: {
    handleSubmit(){
       this.$axios({
         type: 'get',
         url: '/gra/list'
       }).then(res => {

         console.log(res)
       }).catch(err=>{

         alert(err)
       })
    },

    //开始画图了
    drawLine(){

      // 基于准备好的dom，初始化echarts实例
      //var myChart = this.$echarts.init(document.getElementById('main'));
      let myChart = this.$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);

    }
  }
}
</script>

<style>
