Solved
Hi
As far as I know, the application events can be bound to a service to complete actions like playing a sequence. One of the ways to alter the gauge visibility is by defining a javascript function on Home.js and call it in the application event.
$scope.GaugeVisibility = function()
{
$scope.view.wdg['3DGauge-1']['visible'] = true;
}
Hope this helps!
