Rails 3 Impressionist indexing by day
===

I am using the Ruby gem Impressionist. It gives you the ability to look at a count of page hits from a specific date to today date. I'm trying to get the hits from the past 7 days but spit out the number for each day.

    @widget.impressionist_count(:start_date=>"2011-01-01")  #specify start date only, end date = now

How would I do that? I want 7 days ago but for each day to give me the exact count for that day.
