我最近切换到Google Maps API V3.我正在编写一个简单的例子来绘制数组中的标记,但是我不知道如何相对于标记自动居中和缩放.

我搜索了网络的高低,包括谷歌自己的文档,但没有找到一个明确的答案.我知道我可以简单地采用坐标的平均值,但是如何相应地设置缩放？

function setMarkers(map, locations) {

  var image = new google.maps.MarkerImage('images/beachflag.png',

      new google.maps.Point(0,0),
      new google.maps.Point(0, 32));
    var shadow = new …
