Tableau 10 : Vol 6 : Level of Detail Expressions

Learn about Level of Detail (LOD) Expressions with Tableau 10. The video shows examples of using LOD Expressions with Tableau 10. Tableau LOD expressions are a method used to compute aggregations that are not at the level of detail of the visualization. There are three types of LOD expressions: 

  • Fixed
  • Include
  • Exclude

Fixed: Calculates the aggregation at the level of detail specified in the calculated field regardless of any dimensions in the view. 

Include: Calculates the aggregation at the level of detail specified by the dimensions in the view and the dimensions included in the calculated field. This can result in the calculation of the aggregation at a lower level of detail than the view. 

Exclude: Calculates aggregation at the level of detail specified by the dimensions in the view, excluding any listed in the calculated field. This can potentially result in the calculation of the aggregation at a higher level of detail than in the view.
