Hope you can help with a small issue I'm struggling with. I've attached my workbook.
I have a map and I would like to control what shows using a parameter (for each year of sales).
I have all of my sales data in one column and I also have another column for Year in the table.
The parameter is a year selector, and when I select a year on the parameter, I would like that year's data to show on the map.
I can get this working if I have a separate column for each year's data, but this is difficult to build and not very efficient.
Any help would be greatly appreciated.
(Please bear in mind I'm on Tableau Public, so any help you give will need to be uploaded to Public).
Just convert Year_Marr to discrete, add it to the sheet as a filter and show it as a quick filter. You can make that a "Single Value (Slider)" and it will look like the parameter you currently have.
