cannot push markers on map although have latitude and longitude points ?

[ahmed elbarbary]

I using angular 7

 

google map already display without points pushed on it .

 

meaning all points not display on map although i have latitude and

 

longitude for more points 

 

but these points not exists on map . 

 

step 1 : on html component

<agm-map 

 
  [latitude]="lat"  
  [longitude]="lng"  
  [zoom]="zoom"  
  [disableDefaultUI]="false"  
  [zoomControl]="false">  
 
  <agm-marker  
      *ngFor="let m of markers;"  
      [latitude]="m.lat"  
      [longitude]="m.long"  
      >  
     
  </agm-marker>  
   
 
 
</agm-map>  

 step2 :service.ts

getLocationData(ids: Array<number>) {   

 
        let observableBatch = [];  
     
      ids.forEach((id) => {  
     
            observableBatch.push(  
                  this.http.get('http://192.168.7.45:9200/location/_doc/'+id)  
                          .map(res => res ));  
        });  
     
        return Observable.forkJoin(observableBatch);  
    }  

 

step3 :on component.ts

export class ManagelocationsComponent implements OnInit, AfterViewInit {
markers=[];


this.partDetailsService.getLocationData(locationArr).subscribe(res => {  
          res.forEach((item, index) => {  
       
            let dataLocation = res[index]['_source']['GPS1'];  
            var loc = dataLocation.split(',');  
            this.markers.push(  
              parseFloat(loc[0].trim()),  
              parseFloat(loc[1].trim())  
           })  
console.log("marker values is" + this.markers);  

Result points for latitude and longitude from browser console :

 

marker values is

5.2951916,100.28825170000005,30.788892,120.632503,13.658933,100.634069,10.328074,123.983185,31.332119,120.723465,31.9195204,120.1029251,18.588375,99.033632,31.301726,120.673733,31.306624,121.616856,14.3091,121.033,22.783944,113.798342,14.173507,121.129545,29.9211,103.797,10.328071,123.98318500000005,2.679124,101.978932,
