How to use 'There is ... for you'?

I am not sure how to use this expression: "There is ... for you."

I understand that it is used in reference to something negative, but can it be used to describe something positive such as:

There was Andy for you, so cheerful and confident.

Please enlighten me on the use of this expression. Thanks in advance.

It's fine to use the expression both positively and negatively.

Thank you, Rover.
