I have simple 4 fields in my data, Year number, Week number, Weekend date and Sales measure.
I would like to visualize previous week sales verses last year sales for same week.
Example.
If I am currently into week 30 of year 2017. Then I would like to compare 2017-week 29 verses 2016-week29. and then show the variance of the two values. It should automatically update every week to show the previous week.
Please advice.
