i'm trying to hide/show markerClusterer when user clicks some buttons:

Here is what i'm trying to do:

    map = new google.maps.Map(document.getElementById(mappa),mapOptions);

    var marker_tmp = [];

    var markers_tmp = [];

    $.each(json,function(index,value){

        var latLng = new google.maps.LatLng(value.lat,value.lng);

        var marker = new google.maps.Marker({'position': latLng});

        if((value.candidato in markers_tmp)==false){

            markers_tmp[value.name]=[];

        }

        markers_tmp[value.name].push(marker);

    });

    for(var name in markers_tmp){

        markers[name]= new MarkerClusterer(map,markers_tmp[name]);

    }

I create multiple markerClusterer each one is associated to a particular name.

So i have some buttons associated to these particular name and i need to hide/show the marker clusterer associated with that button.

/*This is the function associated to a button when it is clicked*/

function hide_show_cluster(name,visible){

    var tmp_cluster = markers[name];

    //call a function of markerClusterer (tmp_cluster) to hide/show it

}

I've done lots of tests but no one satisfy my request.
Can someone help me? Thanks!
