Google Maps API: Calculate Center/Zoom of Polyline

I have an overlay that is dynamically generated from user data, so I need to know how to find the center of that overlay.

Currently, I am just using the first coordinate

Answer 1

Based on @tux21b,

      var bounds = new google.maps.LatLngBounds();
      polyline.getPath().forEach(function(e){//can't do polyline.getPath()[i] because it's a MVCArray
          bounds.extend(e);
      })         
      _map.fitBounds(bounds);
