Google maps API V3 method fitBounds

Question

I have this code that renders a map   function initialize         var myOptions           center  new google maps LatLng 45 4555729  9 169236         zoom  13        mapTypeId  google maps MapTypeId ROADMAP   panControl  true  mapTypeControl  false  panControlOptions                position  google maps ControlPosition RIGHT CENTER            zoomControl  true  zoomControlOptions        style  google maps ZoomControlStyle LARGE      position  google maps ControlPosition RIGHT CENTER    scaleControl  false  streetViewControl  false  streetViewControlOptions        position  google maps ControlPosition RIGHT CENTER                              var map   new google maps Map document getElementById  mapCanvas            myOptions      var Item 1   new google maps LatLng 45 5983128  8 9172776    var myPlace   new google maps LatLng 45 4555729  9 169236    var marker   new google maps Marker       position  Item 1       map  map     var marker   new google maps Marker       position  myPlace       map  map     var bounds   new google maps LatLngBounds myPlace  Item 1   map fitBounds bounds            Even if the two points are separated from 25 km I get this result     While I would like to render a higher level zoom   Like this    I use the method fitBounds        var bounds   new google maps LatLngBounds myPlace  Item 1       map fitBounds bounds     Thanks for your support

var map   new google maps Map document getElementById  map                     mapTypeId  google maps MapTypeId ROADMAP                  var bounds   new google maps LatLngBounds     for  i   0  i  lt  locations length  i             marker   new google maps Marker               position  new google maps LatLng locations i  1   locations i  2                map  map             bounds extend marker position     map fitBounds bounds

This happens because LatLngBounds   does not take two arbitrary points as parameters  but SW and NE points  use the  extend   method on an empty bounds object  var bounds   new google maps LatLngBounds    bounds extend myPlace   bounds extend Item 1   map fitBounds bounds     Demo at http   jsfiddle net gaby 22qte

I have the same problem that you describe although I m building up my LatLngBounds as proposed by above  The problem is that things are async and calling map fitBounds   at the wrong time may leave you with a result like in the Q  The best way I found is to place the call in an idle handler like this   google maps event addListenerOnce map   idle   function         map fitBounds markerBounds

LatLngBounds must be defined with points in  south-west  north-east  order  Your points are not in that order   The general fix  especially if you don t know the points will definitely be in that order  is to extend an empty bounds   var bounds   new google maps LatLngBounds    bounds extend myPlace   bounds extend Item 1   map fitBounds bounds     The API will sort out the bounds
