Show value of the same month in previous year
I would like to know how to display the value from the previous year from the same month (e.g., Jul 2018 compared to Jul 2018). More specifically, I would like to display the delta to the value from the same month in the previous year. I know about the advanced function "delta from last", but this does not solve my problem as I have month level data.
Is there a function to calculate this? How can I solve the problem?
