<pre>step 1 : on html component

 <pre lang="CSS"><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>

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);

 marker values is
