    How to calc % change from calculated expressions?

      Hello - relatively new to QV.  I'm trying to figure out how to calculate a growth metric (% growth from prior year for example) for selected fields within qv.  I created a couple simple charts (attached) from an excel data source, where the data from excel is organized as follows (example has three years of data through 2010):

       

      CountryYear Units Revenue Region
      US2008     1,000.00            1,000.00 N AMERICA
      Canada2008         200.00                180.00 N AMERICA
      UK2008         300.00                180.00 EUROPE
      Spain2008         350.00                262.50 EUROPE
      Italy2008         275.00                206.25 EUROPE

       

       

      How can I calculate year over year % changes in units and revenues for selected fields?  Within the attached, if you filter on "N America", you would see revenues of 1180, 1330 & 1406.9 for 2008-2010 respectively.  I would like to calc and show the growth metrics of 12.7% (2008 - 1180 to 2009 - 1330) and 5.8% (2009 - 1330 to 1406.9) for 2009 and 2010.
