Switchable Dimensions with Datetime

Hello Everyone, 

I am trying to use Switchable Dimensions on a line chart with a datetime table. The objective is to switch from yearly, monthly, and quarterly timeframes using switchable dimensions. In Sisense's documentation, they give an example that I have tried with no luck. Has anyone tried this before and it working? 

prism.registerSwitchDimension({ 
      widget: widget, 
      dimensions: [ 
         { 
           panel: 'categories', 
           dims: [ 
                { "index":0, 
                "dim":"[dimDate.Date (Calendar)]", 
                "datatype": "datetime", 
                "title":"Weeks", 
                "level": "weeks" 
                }, 
                { "index":0, 
                "dim":"[dimStrategy.strategy]", 
                "datatype": "text", 
                "title":"strategy" 
                } 
             ] 
           } 
      ] 
  });
