vue-cli3整合echarts

闲话少絮，步入正题：
官网api文档直通https://www.echartsjs.com/zh/api.html#echarts

一.下载安装echarts

执行以下命令，安装echarts

npm install echarts -S

// 打印日志如下:
$ npm install echarts -S

二.在项目中的main.js中添加如下代码：

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

三.新建echarts-demo.vue：

<template>
  <div>
    <div id="echartsDemo" style="width: 500px;height: 500px;"></div>
    <div id="echartsBarDemo" style="width: 500px;height: 500px;"></div>
  </div>
</template>
<script>
export default {
  data () {
    return {
      content: ''
    }
  },
  mounted () {
    this.drawLine()
    this.drawBar()
  },
  methods: {
    drawLine () {
      let elementById = document.getElementById('echartsDemo')
      let echartsDemo = this.$echarts.init(elementById)
      let option = {
        title: {
          text: 'ECharts 示例'
        },
        tooltip: {},
        legend: {
          data: ['销量']
        },
        xAxis: {
          data: ['衬衫', '羊毛衫', '雪纺衫', '裤子', '高跟鞋', '袜子']
        },
        yAxis: {},
        series: [{
          name: '销量',
          type: 'bar',
          data: [5, 20, 36, 10, 10, 20]
        }]
      }
      echartsDemo.setOption(option)
    },
    drawBar () {
      let echartsBarDemo = this.$echarts.init(document.getElementById('echartsBarDemo'))
      echartsBarDemo.setOption({
        backgroundColor: '#2c343c',

        title: {
          text: 'Customized Pie',
          left: 'center',
          top: 20,
          textStyle: {
            color: '#ccc'
          }
        },
        tooltip: {
          trigger: 'item',
          formatter: '{a} 
{b} : {c} ({d}%)'
        },
        visualMap: {
          show: false,
          min: 80,
          max: 600,
          inRange: {
            colorLightness: [0, 1]
          }
        },
        series: [
          {
            name: '访问来源',
            type: 'pie',
            radius: '55%',
            center: ['50%', '50%'],
            data: [
              { value: 335, name: '直接访问' },
              { value: 310, name: '邮件营销' },
              { value: 274, name: '联盟广告' },
              { value: 235, name: '视频广告' },
              { value: 400, name: '搜索引擎' }
            ].sort(function (a, b) { return a.value - b.value }),
            roseType: 'radius',
            label: {
              normal: {
                textStyle: {
                  color: 'rgba(255, 255, 255, 0.3)'
                }
              }
            },
            labelLine: {
              normal: {
                lineStyle: {
                  color: 'rgba(255, 255, 255, 0.3)'
                },
                smooth: 0.2,
                length: 10,
                length2: 20
              }
            },
            itemStyle: {
              normal: {
                color: '#c23531',
                shadowBlur: 200,
                shadowColor: 'rgba(0, 0, 0, 0.5)'
              }
            },
            animationType: 'scale',
            animationEasing: 'elasticOut',
            animationDelay: function (idx) {
              return Math.random() * 200
            }
          }
        ]
      })
    }
  }
}
</script>
