Tableau
Introduction to Data Visualization
The Power of Visuals: Why Tableau? Comparing Tableau vs. Excel vs. Power BI.
The Tableau Ecosystem: Understanding Tableau Desktop, Public, Server, and Online.
The Interface: Shelves, cards, the data pane, and the toolbar.
Connecting to Data: Importing Excel, CSV, and PDF files; Live vs. Extract connections.
Building Basic Visualizations
Dimensions vs. Measures: Understanding how Tableau categorizes data.
Discrete vs. Continuous: The “Blue vs. Green” pill concept.
Core Chart Types: * Bar Charts and Stacked Bars.
Line Charts and Area Charts.
Pie Charts and Heat Maps.
Sorting & Filtering: Basic filters, top-N filters, and manual sorting.
Advanced Data Manipulation
Groups & Sets: Categorizing data points for deeper analysis.
Hierarchies: Creating “Drill-down” features (e.g., Year > Quarter > Month).
Data Joining & Blending: Combining multiple data sources.
The Relationships Model: Understanding the “Noodle” (Logical vs. Physical layers).
Calculated Fields & Parameters
Basic Calculations: Arithmetic, string manipulation, and date functions.
Quick Table Calculations: Running totals, percent of total, and year-over-year growth.
Logic Statements: Using
IF,THEN,ELSE, andCASEfunctions.Parameters: Giving users control over inputs and “What-If” scenarios.
Level of Detail (LOD) Expressions
Introduction to LODs: Why they are the most powerful tool in Tableau.
FIXED LOD: Calculating values regardless of the view’s granularity.
INCLUDE & EXCLUDE: Fine-tuning calculations for specific visual contexts.
Mapping & Spatial Analysis
Geocoding: How Tableau recognizes cities, states, and zip codes.
Custom Maps: Adjusting background layers and map styles.
Symbol vs. Filled Maps: Choosing the right visual for geographic data.
Dual Axis Maps: Overlaying two different data types on one map.
Dashboarding & Storytelling
Dashboard Best Practices: Layout, white space, and “The F-Pattern” of reading.
Actions: Creating Interactivity (Filter Actions, Highlight Actions, URL Actions).
Device Designer: Making dashboards mobile-friendly.
Tableau Stories: Sequencing visualizations to lead an audience to a conclusion.
