Rails ActiveRecord group_by & sum db results for use with Lazy HighChartsI am completely new to RoR/Ruby and i am using Lazy High Charts gem to generate some purdy charts based on some database information. I have tried the answers that were provided in a previous question but i am still a bit confused as to how to do this.. I need to sum amount_used, and billed_amount and group by month/year (e.g; Aug/2012) The end result will be something similar to a dual axis chart
