In our previous article, we had shown you the basic approach to calculate rank in Tableau. In this article, we will show you how to calculate Tableau Rank using the table calculation with an example.
For this Tableau rank calculation, we are going to use the Employee table present the SQL Server. I suggest you to refer Connecting to SQL Server and rank articles to understand the configurations. The following screenshot will show you the data inside the Tableau Table, and as you can see, it has 14 records:
Tableau Rank Calculation Advanced
In this example, we will show you the advanced approach to calculate the tableau rank. For this Tableau Rank calculation, we are going to Drag and Drop the Occupation, Last Name, and First Name from Dimensions Region to Rows Shelf. Next, drag the Yearly Income from Measures region to Text filed present in the Marks Shelf.
To assign the Tableau Ranks, we have to add the table calculation. To do so, click on the Down arrow beside the Yearly Income measure (change as need). Or right-click on it will open the context menu. From the list of available options, please select the Create option and then Calculated Field… option.
Once you click on the Calculated Field… option, a new window will be opened to write the calculation.
Tableau RANK Function
In this example, we will calculate the rank so, we are using the Tableau RANK function. The Rank function in Tableau accepts two arguments first, aggregated measure (or an expression) second, ranking order (ascending, or descending). Here the second argument is optional, and by default, it assigned as DESC (descending).
The Tableau Rank Function will assign the same rank to an identical value. For example, if we have 100, 200, 200, 400 then the function will return the ranks as 1, 2, 2, 4 in ascending order
TIP: Click on the arrow that we rounded to show or hide the existing function. You can search for the required function, and then check its syntax by selecting one.
Once you click on the OK button, it will assign the ranks for each record based on the Yearly Income values
Edit Tableau Rank Function
To edit the existing table calculation, please click on the down arrow beside the table calculation will open the context menu. Here you have to select the Edit Table Calculation option.
Once you click on the Edit Table Calculation option, a new window called Table Calculation will open. As you can see, ithas selected the Compute using option as Table (down) by default.
Let us change the Compute using option from Table (down) to Specified Dimensions (Occupation, Last name, and First Name). Note, we are selecting the Occupation dimension for the Restarting every option. It will allow to assign the ranking for each Occupation. Or we can say, Rank yearly income partitioned by Occupation.
Now you can see the result of this Tableau rank function. It is calculating the Rank for each Partition (here, it is Occupation)
Tableau RANK_DENSE Function
In this example, we are using the Tableau RANK_DENSE function. This Tableau rank function accepts two arguments first, aggregated measure (or an expression) second, ranking order (asc or desc). Here, the second argument is optional, and by default, it will assign DESC (descending).
The Tableau Rank_dense Function will assign the same rank to identical value, but it will not skip the next rank. For example, if we have 100, 200, 200, 400, then the function will return the ranks as 1, 2, 2, 3 in ascending order.
To change the existing table calculation, click on the down arrow beside the table calculation, and select the Edit.. option.
Let us change the function name from RANK to RANK_DENSE or write down your custom function and click OK.
As you can see the result, It is calculating the Dense Rank for each Partition (here, it is Occupation)
Tableau RANK_MODIFIED Function
In this example, we are using the Tableau RANK_MODIFIED rank function. This function accepts two arguments first, aggregated measure (or an expression) second, ranking order. Here, the second argument is optional, and by default, it will assign DESC (descending).
The Tableau Rank_Modified Function will assign the same rank to an identical value. The Highest value will rank as 1, and the following two equal amounts will rank as 3. For example, if we have 100, 200, 200, 400 then the function will return the ranks as 1, 3, 3, 4 in ascending order
It is calculating the Modified Rank for each Occupation
Tableau RANK_PERCENTILE Function
We are using the Tableau RANK_PERCENTILE function. This Tableau Percentile function accepts two arguments one, aggregated measure (or an expression) second, ranking order (ascending, or descending).
In Tableau PERCENTILE function, the second argument is optional, and by default, it is assigning the DESC (descending).
Now you can see the result of this Tableau Rank function. It is calculating the Percentile Rank for each Occupation
Tableau RANK_UNIQUE Function
In this example, we are using the Tableau RANK_UNIQUE rank function. This function accepts two arguments first, an expression second, ranking order (ascending, or descending). Here, the second argument is optional, and by default, it will assign DESC (descending).
The Tableau Rank_UNIQUE Function will assign the unique rank to an identical value. For example, if we have 100, 200, 200, 400 then the function will return the ranks as 1, 2, 3, 4 in ascending order
See the Tableau RANK_UNIQUE function result. It is assigning the Unique Rank for each item present in the Occupation.
