I took a look at your Viz - try going to the filter shelf and including all 4 quarters in the "quarters filter" - I t had been set to Q1 only - you will need to have at least 2 quarters included - the one you want the result for and the previous one
Hope that works for you
Let me know
Instead of putting Quarter on filter shelf, I moved it to Page self. This way values of the previous quarter can be retained.
My only prob is for Qtr1 2016, previous value should be Qtr4 2015, so % of difference should be Qtr1 2016 - Qtr4 2015
How do i let tableau do it i have attached updated workbook..
Workbook_10.0_qtr_new.twbx 5.3 MB
See the attached
I had to use "Ship Date" to get any 2016 data but the principal remains the same - see the 2 red tabs - one is a table which shows all the Q/Q % change data - the other is the chart that you want - see how the filters are arranged - the "Quarters filter" use a Qrt-Yr format that you get by right clicking the simple quarter filter from your file
Let me know if this worked for you
