Can someone supply a brief example of proper syntax for defining and accessing aggregates on a datasource? I am unable to access any aggregates results (function keeps returning UNDEFINED). I must be missing something trivial. Modified fiddle sample I am experimenting with:

Hello Andrew,
The aggregates method returns a object which as keys has the field name and as value the another object that contains the value for every aggregate. I.e you should retrieve the sum aggregate for stock field as follow:
dataSource.aggregates().stock.sum
Another thing you should notice is that when you call any method that applies some sort of transformations of the data you should handle change event of the DataSource. This event will be triggered when the data manipulation is finished and you can be sure that the data you access is the latest.
For more details please see the updated version of the fiddle from your post:
