You might also just get the counts from the database directly:
results = User.find(:all,
:select => 'DATE(created_at) as create_date, COUNT(*) as
user_count',
:conditions => { :created_at => start_date..end_date },
:group => 'DATE(created_at)').
map{|u| [Date.parse(u.create_date), u.user_count.to_i]}
data = date_range.map {|d| [d.strftime("%d %b"),
(results.assoc(d) || [nil,0])[1]] }
Or better yet, use User.count instead of .find .
But the OP wanted counts by day, not a single total.
