They're comparable to Totals and Reference Lines.ĮXCLUDE can't be used in row-level expressions (where there are no dimensions to omit). They can modify a view-level calculation or other LODs. Now you can see how the average sum of sales per state varies across categories and segments.ĮXCLUDE level of detail expressions declare dimensions to omit from the view level of detail.ĮXCLUDE is useful for 'percent of total' or 'difference from overall average' scenarios. When Segment is added to the Columns shelf and the calculation is moved to Label, the LOD expression results update. The resulting visualization averages the sum of sales by state across categories. The calculation is placed on the Rows shelf and is aggregated as an average. This INCLUDE level of detail expression calculates sum of sales on a per-state basis: With the LOD on the Rows shelf, aggregated as AVG, and on the Columns shelf, the view shows the average customer sales amount per region: Name the calculation, Sales Per Customer.In the Calculation editor that opens, do the following:.Select Analysis > Create Calculated Field.You can use an LOD expression to do this. Instead of the sum of all sales per region, perhaps you want to also see the average sales per customer for each region. From the Data pane, under Measures, drag Sales to the Rows Shelf.Ī bar chart showing the sum of sales for each region appears.From the Data pane, under Dimensions, drag Region to the Columns Shelf. Open Tableau Desktop and connect to the Sample-Superstore saved data source.How to create LOD expressionsįollow along with the steps to learn how to create and use an LOD expression in Tableau. This article explains the types of LOD expressions you can use in Tableau, when to use them, and how to format them. They can be performed at a more granular level (INCLUDE), a less granular level (EXCLUDE), or an entirely independent level (FIXED). However, LOD expressions let you control the granularity you want to compute. Level of Detail expressions (also known as LOD expressions) allow you to compute values at the data source level and the visualization level.
