Populate Aggregate snap with Pipeline Parameter

So I’d like to use the value of a pipeline parameter as the field in the Aggregate snap. Can this be done, and if so, how?

    Specify the field name, including “$” in the pipeline parameters:

    Then use the “eval()” function in the Aggregate snap:

    This doesn’t set the result field name, but that can be done in a subsequent mapper if needed.

Hi  tlikarish 
I saw your pipeline, its perfect but I have one more requirement.
If I want to spit the date by quarterly can you please let me know where we need to change the pipeline for it.
For examp:
Input:

We just need the start_date and end_date by quarterly. 

 

THANKS IN ADVANCE.

    Yes @Gayathry , try this:

    $group.filter(x=>x.keys().length != 0).length > 0
