We are trying to compare production totals by weekday and date for a selected week against the previous week. Here's an Excel example of what this view should look like. The user needs to be able to enter a start date and end date or use some type of WeekSelect parameter for the week comparison they want to view.
We have tried a number of things to get this to work in Tableau. I feel I'm pretty close, but something is not quite right as I am unable to total the rows and add the Difference columns.
Any help would be very much appreciated.
I've attached a twbx so you can see what we have done so far.
