## How to extract just the IN count of a Tableau set

tableau count number of records in a group

tableau count number of records with same value

tableau number of records by dimension

how to count values in tableau

sum of count in tableau

tableau total count

tableau row count

How can I extract the IN count portion of a Tableau set? I can see the IN/OUT counts when I drop the set into Text but can't figure out how to get at the IN value by itself.

Ultimately, I want to create a Pie Chart of three sets with just the IN counts as the measures.

I am using Tableau Public if that is a factor.

You have to be a little careful about specifying what you wish to count.

One way to think of a set is as a Boolean function that gives a value to each data record denoting whether that record is associated with the set.

Another way to think of a set is as a mathematical set whose members are a subset of the values for some discrete field. (Or Tuple of fields)

The difference between the two views is really just a mindset, whether you consider the set as a Boolean function whose domain is a data row in the data source, or whose domain is the field on which the set definition is based.

Say you are looking at Tableau’s Superstore data set where each data record is a line item for a product attached to an order.

If your set is based on the field Region, say its called [My Favorite Regions] and currently contains {"East", "Central"} do you want your count to be 2 (i.e. the number of regions in the set) ? Or do you want your count to be in the tens of thousands (i.e the number of line items on orders from the regions in the set)? Or something in between, maybe the number of distinct orders (i.e. order ids) within the selected regions...

If you want to count data rows that are associated with the set, you can simply filter by the set and calculate SUM([Number of Records[). If you want to count the regions in the set even though the level of detail of the data is at the order line item level,then you’ll have to use either a COUNTD to count the distinct regions, or some approach to specify what it is you want Tableau to count.

For example, put your set on the filter shelf, and show COUNTD(Region) which could be slow for very large data sets. To get the same effect without an explicit filter, you can define a LOD calculation such as:

{ COUNTD(if [My Favorite Regions] then [Region] end) }

Or you could use a table calc with the SIZE() function to do the calculation in the Tableau client instead of by the data source.

**How to Show Top 10 Lists in Tableau Tooltips,** 1. Re: Get the count from a set. Hi Pratik, If you drag the Set you created out onto your view, then drag Number of Records up to the Label section of the Marks card, you should be able to see how many are in and out of your set. This function is not available in the following cases: workbooks created before Tableau Desktop 8.2 that use Microsoft Excel or text file data sources, workbooks that use the legacy connection, and workbooks that use Microsoft Access data sources. Extract your data into an extract file to use this function. See Extract Your Data.

Not sure what your data looks like but you could set a certain condition when creating a set or split the IN/OUT into two different sets. Here's a link to sets in Tableau.

of Records measure onto the row or column shelf. You cannot refresh the extract. When connecting directly to an extract, Tableau treats that file as the true source, as opposed to a clone of underlying data. So, it's not possible to relate it back to your source data. The data model and relationships will be lost. The data model and relationships between the tables is stored in the .tds file and not in the .hyper file, so this information is lost when connecting directly to the .hyper file.

You can do this with an if statement

IF [set] = TRUE THEN 1 ELSE 0 END

Then I suppose you could sum this calculated field

The most common usage is when you have a lot of categories and want to create an 'Other' category based on the categories that aren't in a set, if the set is a "Top N Set"

To do this:

IF [set] = TRUE THEN [dimension] ELSE 'Others' END

How do you show only the top 10 values in tableau? Right click datasource --> extract --> Appen Data from file; Select the file to append the data from the extract. The file could be csv, excel, twb or tde extension. Therefore, it is possible to append an extract to the existing extract. Cons: Appending data to an extract is a manual effort and needs to be accomplished via Tableau desktop.

Below are some examples using the sample data set Superstore. CLICK TO EXPAND SOLUTION. Example 1: Using a Range of Values with Assuming you have the permission, you can download the extract from Tableau Server as a.tdsx file. You can then open an instance of Tableau Desktop and connect to the.tdsx as a data source. In Tableau Desktop, you would right-click on the data source and uncheck Use Extract.

Supports large data sets: You can create extracts that contain billions of rows of or supported by the original data, such as the ability to compute Count Distinct. a database view that contains just the data you need for your extract and then In Tableau Server or Tableau Online you can only aggregate the members of the set into In/Out categories. Show In/Out members in a set. In most cases, when you drag a set to the viz, Tableau displays the set using the In/Out mode. This mode separates the set into two categories: In - The members in the set. Out - The members that aren't part of

I'm just wondering, can anyone explain what's happening when tableau So if you have 1,000 rows and 20 columns it will count as 20,000 rows in My data set only has 1000 rows, currently waiting for the Extract to finish Create your chart at the grain you are counting, i.e. Products, Customers, etc. Category, Subcategory, Product. Now, we need to count the number of products within each subcategory. However, we cannot use the built-in COUNT () function because it counts at the grain of the data set, which is at the order line level.

##### Comments

- Excellent. I will review what I'm trying to 'really' do and rethink it through. This is very helpful to help me make sure I'm using sets with the right mentality.
- This answer made me really think through what I was after. I was able to use sets along with a filter to get what I wanted. Thank you.
- "[set] = TRUE" is redundant. You can just type "[set]"
