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
