Google Map API v3 — set bounds and center

Yes, you can declare your new bounds object.

 var bounds = new google.maps.LatLngBounds();

Then for each marker, extend your bounds object:

bounds.extend(myLatLng);map.fitBounds(bounds);

API: google.maps.LatLngBounds

Got everything sorted - see the last few lines for code - (bounds.extend(myLatLng); map.fitBounds(bounds);)

function initialize() {  var myOptions = {    zoom: 10,    center: new google.maps.LatLng(0, 0),    mapTypeId: google.maps.MapTypeId.ROADMAP  }  var map = new google.maps.Map(    document.getElementById("map_canvas"),    myOptions);  setMarkers(map, beaches);}var beaches = [  ['Bondi Beach', -33.890542, 151.274856, 4],  ['Coogee Beach', -33.923036, 161.259052, 5],  ['Cronulla Beach', -36.028249, 153.157507, 3],  ['Manly Beach', -31.80010128657071, 151.38747820854187, 2],  ['Maroubra Beach', -33.950198, 151.159302, 1]];function setMarkers(map, locations) {  var image = new google.maps.MarkerImage('images/beachflag.png',    new google.maps.Size(20, 32),    new google.maps.Point(0,0),    new google.maps.Point(0, 32));  var shadow = new google.maps.MarkerImage('images/beachflag_shadow.png',    new google.maps.Size(37, 32),    new google.maps.Point(0,0),    new google.maps.Point(0, 32));  var shape = {    coord: [1, 1, 1, 20, 18, 20, 18 , 1],    type: 'poly'  };  var bounds = new google.maps.LatLngBounds();  for (var i = 0; i < locations.length; i++) {    var beach = locations[i];    var myLatLng = new google.maps.LatLng(beach[1], beach[2]);    var marker = new google.maps.Marker({      position: myLatLng,      map: map,      shadow: shadow,      icon: image,      shape: shape,      title: beach[0],      zIndex: beach[3]    });    bounds.extend(myLatLng);  }  map.fitBounds(bounds);}

My suggestion for google maps api v3 would be(don't think it can be done more effeciently):

gmap : {    fitBounds: function(bounds, mapId)    {        //incoming: bounds - bounds object/array; mapid - map id if it was initialized in global variable before "var maps = [];"        if (bounds==null) return false;        maps[mapId].fitBounds(bounds);    }}

In the result u will fit all points in bounds in your map window.

Example works perfectly and u freely can check it here www.zemelapis.lt
