setup Xfield for birth

Great plugin! Really helps a lot understanding what users are doing in a community.

I´m wondering from which Xfield the plugin get´s the data for “Buddypress Birth Chart”.
My Xfield is named “birth”, but nothing is being displayed – how can I setup this?

It would be cool adding some other fields (gender, etc.). Maybe by adding them by dropdown from available Xfields.
