Jquery 如何使用gMap将带有多个标记的地图居中？

我正在使用jQuery的gMap插件。在我的地图上有几个记号笔。如何基于标记的范围将地图居中？然后，如果可能的话，稍微缩小以在最外面的标记和地图边缘之间留一个边距

谢谢

//Zoom and center the map to fit the markers  
//This logic could be conbined with the marker creation.  
//Just keeping it separate for code clarity.  
var bounds = new google.maps.LatLngBounds();  
for (index in markers) {  
    var data = markers[index];  
    bounds.extend(new google.maps.LatLng(data.lat, data.lng));  
}  
map.fitBounds(bounds);
