Laravel-5 independant functionality

I'm looking for a way to create an encapsulated functionality for retrieving and calculating chart data from the database.

Basically what I want is to be able to create an object in controllers and then pass that object to the view.

I do have an understanding on how to make helper classes/methods, but how should I go about adding requests to the database and such?

Mashing everything in a single class just seems wrong.
