I want to compare the percent of sales for each state using the range of dates with slider. For example, I want to be able to get the percentage difference in the sales for Nov-2011 to Feb-2012 compared to Nov-2010 to Feb-2011. (annual difference)
Helps are appreciated.
Do you want an arbitrary time range or specific? Because if you want an arbitrary time range, you're going to need a solution like this one here: http://community.tableau.com/thread/117545. If you have a specific time range, then you will end up with something more like this one: http://community.tableau.com/thread/112972
