echarts数据按横坐标补齐

echarts数据渲染时横坐标是动态的，查询出来的数据需要按横坐标填充，没有的就设置为0

let doctorMap= new Map();
let nurseMap= new Map();
 this.xAxisList=['00', '01', '02', '03', '04', '05', '06', '07', '08',
  '09', '10', '11', '12', '13', '14', '15', '16', '17', '18',
  '19', '20', '21', '22', '23'
]
//1.数组对象转map
 res.data.ret?.doctorList.forEach(item=>doctorMap.set(item.TIME_HOUR,item.count));
 res.data.ret?.nurseList.forEach(item=>nurseMap.set(item.TIME_HOUR,item.count));
 let doctorArray = []
 let nurseArray = []
 this.xAxisList.forEach(x_item=>{
     //判断map中是否存在某值
   if(doctorMap.has(x_item)){
     doctorArray.push(doctorMap.get(x_item))
   }else{
     doctorArray.push(0)
   }
   if(nurseMap.has(x_item)){
     nurseArray.push(nurseMap.get(x_item))
   }else{
     nurseArray.push(0)
   }
 })
 this.setChart(doctorArray, nurseArray)
