For a couple days I have been trying to come up with a solution to my problem but I cannot seem to find the answer. Maybe one of you can help.
I want to see the month over month sales . I give an example let's take two months data December 2016 and January 2017 if i use the percentage difference in tableau i get the result based on total sales in December and January but practically i don't have total sales in January so i want to compare only one January 1-5 to the December 1-5.
What are your suggestions and ideas for how to handle this?
