I have a data set which shows the target points that a sales representative has gained across 4 key products by month for 2013. What I have done so far is to put this data into a table and sorted it by the row grand total to provide a kind of make shift league table.
Sales Rep Product A Product B Product C Product D Grand Total (Sorted)
Person A 10 20 30 10
Person B 11 15 22 10
Person C 10 10 10 10
What I would like to do is to provide an indicator on the sales representatives rank movement from the previous month.
For example if the user selects February as a month to review, currently they get a league table as mentioned, what I would like to do is to have an arrow shape indicate how each sales representative has moved since the previous month, in this instance January.
How do I do this in Tableau?
Any help is much appreciated!
