谷歌地图fitBounds无法正常工作

我正在使用带有angularjs指令的谷歌地图创建旅行视图。除了可以将谷歌地图拟合到经度集合外，其他所有方法都可以正常工作。我一直尝试使用fitbounds方法，但是失败了。

谢谢，

以下是我的代码工作。

指示：

 <div class="trip-google-map" trip-map="" mapid="2" latitude="22.998673" longitude="72.514346"></div>

指令代码：

app.directive('tripMap', function ($compile) {
    return {
        controller: function ($scope, $location, mapService) {
            this.registerMap = function (myMap) {
                mapService.setTripMap(myMap);

            };
        },
        link: function (scope, elem, attrs, ctrl) {

                map;
            latitude = attrs.latitude;
            longitude = attrs.longitude;

                }, 100);
            });
        }

    };
});

控制器代码：

app.controller('tripdetailController', ['$scope', '$rootScope', '$timeout', 'mapService', 'ngDialog', function ($scope, $rootScope, $timeout, mapService, ngDialog) {
        $scope.tripPathPolylines = [];
        var trips = [];
        var insertTripLatlng = function (trip) {
            var isExists = false;
            for (var v in trips) {
                if (trips[v].hash == trip.hash) {
                    isExists = true
                    break;
                }
            }
            if (isExists == false) {
                trips.push(trip);
            }
        }
        function settrip() {
            var marker;
            var tripmap = mapService.getTripMap();
            var bounds = new google.maps.LatLngBounds();
            for (var j = 0; j < trips.length; j++) {
                var ltlng = new google.maps.LatLng(trips[j].lat, trips[j].lng);
                bounds.extend(ltlng);

                marker = new google.maps.Marker({
                    position: ltlng,
                    map: tripmap
                });

            }
            tripmap.fitBounds(bounds);
        }
        $scope.InitializeTripdetailController = function () {
            var tripData = $scope.$parent.ngDialogData;
            for (var p = 0; p < tripData.messages.length; p++) {
                insertTripLatlng({ lat: tripData.messages[p].trackPoint.pos.lat, lng: tripData.messages[p].trackPoint.pos.lng, hash: tripData.messages[p].trackPoint.pos.lat + "-" + tripData.messages[p].trackPoint.pos.lng })
            }
            settrip();
        }
    }]);

FitBounds代码：

 var tripmap = mapService.getTripMap();
 var bounds = new google.maps.LatLngBounds();
 for (var j = 0; j < trips.length; j++) {
     var ltlng = new google.maps.LatLng(trips[j].lat, trips[j].lng);
     bounds.extend(ltlng);
     marker = new google.maps.Marker({position: ltlng,map: tripmap});
  }
  tripmap.fitBounds(bounds);

该地图如下所示：

应该在fitbounds之后为：

更新：css for map：

更新：映射被加载到ngDialog弹出窗口中。

 .trip-google-map {
     width: 100%;
     height: 450px;
  }
