I am trying to build a dashboard that has a text table view with one dimension and three different measures. I am trying to figure out how to add a dashboard filter action with a toggle list of the three measures where you can select one and the table will adjust to show the top 25 of that particular measure. Is this possible?
You can use a parameter to do that - or at least to change the measure. I've got a sample workbook that shows how to do that here: | Tableau Public
If you already have the Top N set up, then this should be easy.
