Google Maps API v3: Can I setZoom after fitBounds?

Question

I have a set of points I want to plot on an embedded Google Map (API v3). I\'d like the bounds to accommodate all points unless the zoom level is too low (i.e., zoomed out

I've found a solution that does the check before calling fitBounds so you don't zoom in and suddenly zoom out

var bounds = new google.maps.LatLngBounds();

// extend bounds with each point

var minLatSpan = 0.001;
if (bounds.toSpan().lat() > minLatSpan) {
    gmap.fitBounds(bounds); 
} else {
    gmap.setCenter(bounds.getCenter());
    gmap.setZoom(16);
}

You'll have to play around with the minLatSpan variable a bit to get it where you want. It will vary based on both zoom-level and the dimensions of the map canvas.

You could also use longitude instead of latitude
