                    var tabuser = JSON.parse(localStorage.getItem("myid"));

                    for(i = 0; i < tabuser.length; i++){
                        console.log(tabuser[i].id);
                        displayfilter
                            .user(token,tabuser[i].id)
                            .then(function(data){

                                console.log(data);
                                $scope.numtickets = data;


                            })
                    }

Create a json array:

$scope.numtickets = [];

Keep pushing the value of the keycount:

$scope.numtickets.push(data);

Display the array on the view:

<div ng-repeat="numticket in numtickets">
   {{numticket.count}}
</div>

This is a really good start but it only display the value 'count' of the last array and not every array. I think i have to push the value of 'count' in a new array and then retrieve them easily. Because your method give me several different tab which contain the key 'count' if you see what i mean.

Try using: $scope.numtickets.push(angular.copy(data))

it copy only the last value so it's the same result as before :(

Try this:

.then(function(){       var tabuser = JSON.parse(localStorage.getItem("myid"));          $q.all($scope.tabuser.map(function(obj) {           return displayfilter.user(token,obj.id)         })).then(function(data){             console.log(data);             $scope.numtickets = data;         });   });

i manage it, what i did is just to declare '$scope.numtickets = [];' outside the loop
