Overlay %change on bar graph??? :(

Hey everyone, I am trying to figure out how to overlay a %change line over top of my bar graph. I am showing data over the 4 quarters for a year and I want to have a line that shows how much (%) each quarter has changed (+/-) from the previous but can not figure out how to do this automatically without having to draw my own lines and percentages in . Any sugestions?
Thanks
