gmap2 and clustering

I made a simple map, and loaded all my points from a xml file, genera开发者_Python百科ted by a php file with data from a mysql database.

I works just fine, but now I want to cluster all my point, because some of them are really close, and it looks like a mess.

I've checked this out, but can't seem to get it working. http://googlemapsapi.martinpearman.co.uk/readarticle.php?article_id=2

I hope you guys help me. Thanks.

You call:

var cluster=new ClusterMarker(map, {markers:markersArray } );

before you populate markersArray.

The call GDownloadUrl() is asychronous, so that means that:

var cluster = new ClusterMarker(map, { markers: markersArray });

cluster.fitMapToMarkers();

is being called before you do your stuff in the callback for GDownloadUrl(...). You can fix this by putting the code above inside the GDownloadUrl(...) callback.
