Matthew Burton Jan 21, 2014 10:40 AM (in response to Jonathan Drummey)I used the directions from Jonathan's link (http://kb.tableausoftware.com/articles/knowledgebase/rollingcalculation) and just selected "moving calculation" instead of "moving average" to get the sum of the last 4 quarters relative to each quarter's data point (bar). The only remaining issue was the first 4 bars of the graph didn't have previous bars to sum up to 4 quarters/365 of data....so I hid the last year (2011 for example) and then we have the moving sum of last 365 for each quarter for 2012 and 2013.
Thanks for the response! ...I am new to tableau, but this forum is incredibly helpful.
