Comparison between two different specific periods

[Mnn12]

Hi everyone!

I  was wondering if is possible compare two specific period of time. For example, choose 3 days of April 2017 and 15 days of January 2015. The graphic compare: Sales by country.

Thank you very much.

In my opinion you will have to consider the first period as static measure of sales for the defined period (eg. Sales_01Jan15_15Jan15). 

Then you can compare it with your second period of sales that would be filtered by date selected. here it would be interactive with date slicer.  

Don't know the purpose but carefull when comparing tow period of time that are not comparable as it might drive in wrong conclusions.
