The
JavaScript Initialization Code on this plugin is:
console.log("map zoom: "+this.map.getZoom());
//hide the default UI elements
this.map.setOptions({"disableDefaultUI":true});
this.map.setOptions({"zoomControl":false});
//show the scale control
this.map.setOptions({"scaleControl":true});
It will run once on page load, after the google maps object has been created but before the data is loaded into the map.
