If you try and publish your updated workbook or flow to a prior version of Tableau Server, where those features don't exist, the workbook or flow becomes incompatible Release versions often include a range of new features and updates. In previous releases, version numbers didn't follow the same sequence. A maintenance upgrade ensures that the product includes security and bug fixes.Īs of 2022.3, the version numbers for Tableau Desktop and Tableau Server, and Tableau Prep Builder follow the same sequence. Version number formatĪ release upgrade is when Tableau offers new features and updates the look and feel of the product. See Finding and Resolving Compatibility Issues for more information. For example, if we select 10 tiles, we can then scroll through the unique grade values and see which tile they fall into.This article describes the different version number formats and how to find your version number. This will evenly distribute all the records into the number of tiles you have selected. The ‘Tile Distribution’ section allows you to pick how many tiles you will create. By clicking on the icon will change the icon to AZ and ensure the data is sorted in an ascending order (lowest to highest). ZA demonstrates the field will be sorted in a descending order (highest to lowest). The ZA icon demonstrates how that field will be ordered. By clicking on the dropdown arrow next to Grade in the ‘Order By’ section will allow you to pick any field in your data set. The example above shows this Tile field will be based on Grade as that was the field where the ellipsis menu was used to select the Tile functionality. Let’s move to the right hand side of the calculation editor as before we set up the tiles, we need to understand what each tile will be based on. The default is that the field will create 1 tile and therefore the output is 1. The values that will be contained by the field are shown underneath the name of the field. In the top left corner, you can rename the new data field that will be created from ‘Calculation1’ to something more representative of the output of the field.

You may wish to look at the top students by their grades or alternatively only look at those students that are struggling. Alternatively, if the average spending variance is similar between all the customer tiles there is less reliance on a single subset of our customers.Ĭreating tiles can allow you to filter the data to a smaller subset to focus your analysis. Why is this beneficial? Well looking at the variance in average spending values would allow us to understand if we are reliant on the top spending tile if their average sales value is so much greater than all other tiles. Taking all of the airlines customers’ spending and allocating those customers into 10 tiles would provide 10 average spending values. Looking at the average spend for our fake airline Prep Air’s customers would just provide one number. Why would I want to tile my data set?ĭata sets are increasingly becoming larger so dividing up the data set into smaller chunks can help make analysis easier and faster to process computationally. I’m yet to find a useful reason to take the latter approach so this How To post will focus on creating tiles based on numerical fields. When selecting the measure, the data is sorted by the chosen value in either an ascending or descending order.Ī categorical field can be used in Prep to align the records into tiles but this is then done by alphabetical order. Therefore, we are allocating categorical values like customers, students or employees to tiles based on a measure about them. As covered before, a data sets granularity is based on the categorical data. The allocation of the records in each tile is often based on a measure within the data set. For example, if you want to divide 100 records of data into 5 tiles, each tile will contain 20 records. What is a Tile?Ī tile is a division of the data set based on the number of records in the data set. Like many useful functions when preparing data, the Prep developers have simplified the process of creating Tiles so anyone can easily do this. In Prep Builder 2021.4 the ability to split a data set into equally divided sections called tiles became possible through a couple of clicks. One of the most under appreciated aspects of Tableau Prep is the ability to analyse data whilst you reshape or clean your data.
