Tableau Tutorials

Tableau is where data analysis becomes communication. These tutorials cover the skills analysts use daily: calculated fields that encode business logic, LOD expressions that fix granularity without breaking the view, and dashboard layouts that guide a reader from question to answer without clutter. Every example is built around a real analyst workflow, not a toy dataset.

What you will learn

  • Create calculated fields and parameters that respond to user input
  • Use FIXED, INCLUDE and EXCLUDE LOD expressions to control granularity
  • Build dashboards with containers, filters and interactive actions
  • Choose the right chart type for comparison, trend and distribution
  • Optimize extract performance and avoid slow-running workbooks
