vue中使用echarts制作圆环图的实例代码

<div id="main"></div><script type="text/ecmascript-6"> export default {  //从父组件中接收到的数据  props:{   chartT:{    type:Object,    required:true   }  },  data () {   return {    charts: '',    totalIncome:'',    opinionData: [     {value: Math.abs(this.chartT.imp_rate)},//取绝对值     {value: 100}    ]   }  },  methods: {   drawPie (id) {    this.charts = this.$echarts.init(document.getElementById(id));    this.charts.setOption({     tooltip: {      trigger: 'item',      formatter: '{a}<br/>{b}:{c} ({d}%)'     },     legend: {      orient: 'vertical',      x: 'left',      data: this.opinion     },     color:['#2872ef','#d6d6d6','#fc6e51'],     series: [      {       name: '访问来源',       type: 'pie',       radius: ['90%', '65%'],       avoidLabelOverlap: false,       label: {        normal: {         show: false,         position: 'center'        },        emphasis: {         show: true,         testStyle: {          fontSize: '30',          fontWeight: 'bold'         }        }       },       //根据数值判断颜色//       itemStyle:{//        normal:{//         color:function(params){//          console.log(params)//          console.log(params.dataIndex)//          console.log(params.data.value)//          console.log(params.value)//          if(params.value > 0){//           return "#2872ef";//          }else if(params.value[0] < 0 ){//           return "#fc6e51";//          }//          return "#d6d6d6";//         }//        }//       },       labelLine: {        normal: {         show: false        }       },       data: this.opinionData      }     ]    })   }  },  mounted () {   this.$nextTick(function () {    this.drawPie('main')   })  }, }</script>
