设置缩放和居中以在单击群集时显示群集内的所有标记和群集

Question

我正在使用地址绘制Gmap3中地图内的标记而不是纬度和经度。如何在地图视图中使用所有标记和群集初始加载地图时，如何设置 最大缩放级别并设置中心 。此外，在单击群集时，我需要缩放并 仅显示 特定群集内的标记和子群集。我的地址数组如下所示

         var map = $(this).gmap3("get");
         var latitude = marker.position.k;
         var longitude = marker.position.A;

            map.setCenter( new google.maps.LatLng(latitude,longitude));


      //  alert("Here is the default click event");
      }
    },

            map.setCenter(cluster.main.getPosition());
            map.setZoom(map.getZoom() + 1);
        }
      },
      0: {
