javascript - 中心値を無視するGoogleマップV3

Question

いくつかのマーカーを付けた Google マップを作成しました。ただし、マーカーの 1 つは他のマーカーとは異なります。このマーカーをマップの中央に配置したいと思います。地図を作成しているとき、地図の中心をこのマーカーと同じ場所に設定していますが、無視されているようです。これが私のコードです：

var map; // Global declaration of the map
        var iw = new google.maps.InfoWindow(); // Global declaration of the infowindow
        var lat_longs = new Array();
        var markers = new Array();
        var markerCluster;
        function initialize() {

            centerlat = '53.1957381200000';
            centerlong = '-2.8940324870000';

            if(centerlat=='FALSE' && centerlong=='FALSE') {
                var myLatlng = new google.maps.LatLng(51.4734,-0.137329);
            } else {
                var myLatlng = new google.maps.LatLng(53.1957381200000,-2.8940324870000);
            }
            var myOptions = {
                //zoom: 13,
                center: myLatlng,
                mapTypeId: google.maps.MapTypeId.ROADMAP
            }
            map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);



            var myLatlng = new google.maps.LatLng(52.6274684, -1.1290035);

            var markerOptions = {
                map: map,
                position: myLatlng,
                title: "Head Office"        
            };
            marker_0 = createMarker(markerOptions);

            marker_0.set("content", '<h4>Head Office</h4><p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Quisque quis urna nibh, sed venenatis felis. In hac habitasse platea dictumst.

Quisque vestibulum facilisis risus, in suscipit nisl hendrerit et.</p><p><a href="#contact_form" class="btn btn-primary contact-office" data-office_id="13">Contact This Office</a></p>');

            google.maps.event.addListener(marker_0, "click", function(event) {
                iw.setContent(this.get("content"));
                iw.open(map, this);

            });



            var myLatlng = new google.maps.LatLng(51.489827, -0.196938);

            var markerOptions = {
                map: map,
                position: myLatlng,
                title: "London"     
            };
            marker_1 = createMarker(markerOptions);

            marker_1.set("content", '<h4>London</h4><p>Our London office is based at the Earls Court Exhibition centre. Our central location allows us to offer our award winning services to all venues across the capital.</p><p><a href="#contact_form" class="btn btn-primary contact-office" data-office_id="12">Contact This Office</a></p>');

            google.maps.event.addListener(marker_1, "click", function(event) {
                iw.setContent(this.get("content"));
                iw.open(map, this);

            });



        /* IF the user has performed a search then add a marker showing the center of the search */
        if(centerlat!=='FALSE' && centerlong!=='FALSE') 
        {
            var myLatlng = new google.maps.LatLng(centerlat, centerlong);

            var markerOptions = {
                map: map,
                position: myLatlng,
                title: "Your Location",
                icon : "http://www.google.com/intl/en_us/mapfiles/ms/micons/blue-dot.png"
            };
            marker_you = createMarker(markerOptions);

            marker_you.set("content", '<h4>Your Location</h4><p>This is the approximate location of your search</p>');

            google.maps.event.addListener(marker_you, "click", function(event) {
                iw.setContent(this.get("content"));
                iw.open(map, this);

            });
        }


        var clusterOptions = {
            gridSize: 60,
            minimumClusterSize: 5
        };
        markerCluster = new MarkerClusterer(map, markers, clusterOptions);

        fitMapToBounds();


        }


    function createMarker(markerOptions) {
        var marker = new google.maps.Marker(markerOptions);
        markers.push(marker);
        lat_longs.push(marker.getPosition());
        return marker;
    }

    function fitMapToBounds() {
        var bounds = new google.maps.LatLngBounds();
        if (lat_longs.length>0) {
            for (var i=0; i<lat_longs.length; i++) {bounds.extend(lat_longs[i]);}
            map.fitBounds(bounds);
        }
    }

    window.onload = initialize;
