将对象类型转换为数组并进行key的转换

   getChartData() {

      const { schoolId } = this.chartParams

      this.getEquCountAndType({ schoolId }).then(res => {

        console.log(res)        // {"DV86-LA":7,"55X":1,"DV75-LA":1}

        this.chartData = Object.entries(res).map(([name, value]) => ({

          name,

          value,

        }))

        console.log(this.chartData)       // [{name: "DV86-LA"value: 7}, {name: "DV75-LA"value: 1}, {name: "DV75-LA"value: 1}]

      })

    },
