How can I calculate a distinct count of a dimension in Tableau?

Question

I have Googled this and searched the Tableau forums but I'm coming up empty. How can I calculate a distinct count of City Names using Tableau?

Answer 1

Is it not:

1. Create Calculated Field Analysis->Create Calulatated Field

2. Name it and enter the below formula

   COUNTD([City Name])

3. Then pull that into your measures?

This should give you your total count. Or am I missing something in your question?

Answer 2

Another easy way to tackle this problem:

"we need two information as city name and city name (Count Distinct)"

1.To get city name Select [city name] and drag it to row shelf.

2.Again Drag city name into row shelf and Right click on city name in row shelf and Go into measures and select Count Distinct.
