Google지도 V3 가운데 다중 마커 및 자동 확대/축소 문제

Question

모든 마커를 중앙에두고지도를 자동 확대하여 내지도에 모두 맞게하는 방법을 알아야합니다. 나는 그것을 해결하기 위해 며칠간 머리를 부러 뜨리고있다. 제발 도와주세요.

내 코드

<script type="text/javascript"> 
    var map; 
    var address = new Array(); 
    //we can also create following array with a for loop 
    address[0] = '798 9th Ave, New York, NY'; 
    address[1] = '42 E 29th St, New York, NY'; 
    address[2] = '56 W 25th St, New York, NY'; 
    address[3] = '26 W 21th St, New York, NY'; 

    function initialize() { 
    geocoder = new google.maps.Geocoder(); 
    var latlng = new google.maps.LatLng(-34.397, 150.644); 
    var myOptions = {zoom: 15, center: latlng, mapTypeId: google.maps.MapTypeId.ROADMAP} 
    map = new google.maps.Map(document.getElementById("map_canvas"), myOptions);  

    for (var i=0; i<=address.length; i++) {  
     geocoder.geocode({'address': address[i]}, function(results, status) { 
      map.setCenter(results[0].geometry.location); 
      var marker = new google.maps.Marker({map: map, position: results[0].geometry.location});  
     }); 
    } 
    } 
</script>
