-- When you execute a dashboard with dashboard variables, it automaticaly executes with the default values, even before you have entered the wanted values in the dashboard variables and pressed the 'apply' button.

* If we uncheck the button "Evaluate data during initialization" (by default checked) in a DataSource Request, the query is not executed immediatly anymore when you open a dashboad, only when you press 'apply' it is executed and it is only launched once you filled in the dashboard variables and pressed the 'apply' button.
