Method,: { 
echartsData (Row) { 
  the this . $ NextTick (() => {
      the this . HTTP $ 
          .get ( ` /bus/asset-flaw/chart/${row.assetId}?listType= {$ the this .listType} `) 
          .then (RES => {
             the this .tabData2 = res.data.content.assetStatistics
 // data line graph of 
     the this .lineData (Row)
     // reloaded echarts 
            the this .line ()
 // adaptive window 
            the this .inits () 
          }) 
          . the catch (error => {
            the console.log (Error.message) 
          }) 
    }) 
}, 
  Line () { 
      the this . $ echarts.init ( the this . $ refs.main) .setOption ( the this .option3) 
    }, 
 INITs () { 
      the let Self = the this  / / because this function will change the arrow pointing, pointing to windows. Therefore, this first stored 
      window.onresize = function () { 
        Self. $ Echarts.init (Self. $ Refs.main) .resize () 
      } 
    }, 
// a line graph assignment 
    Linedata (Row) {
       this .option3.title = .text the this .textContent + 'trends' + '-' +  row.startUrl
      the let Asset =this.tabData2.map(x => x.needAttentionCount)
      let findNewCount = this.tabData2.map(x => x.findNewCount)
      let findRecurringCount = this.tabData2.map(x => x.findRecurringCount)
      let findOpenCount = this.tabData2.map(x => x.findOpenCount)
      this.option3.series[0].data = asset
      this.option3.series[0].name = 'A'
      this.option3.series[1].data = findNewCount
      this.option3.series[1].name = 'B'
      this.option3.series[2].data = findRecurringCount
      this.option3.series[2].name = 'C'
      this.option3.series[3].data = findOpenCount
      this.option3.series[3].name = 'D'
      let historyTime = this.tabData2.map(x => x.historyTime)
      // 时间
      this.option3.xAxis.data = historyTime
      this.option3.legend.data = ['A','B','C','D']
    },
}   

2, so that a percentage of the pie chart is not displayed as 0

  0 // hide percentage of 
    lineHide (opt) { 
      opt.data.forEach (Item => {

          item.value = null 
        } 
      }) 
    },
