Introduction (Storytelling + Executive Reporting)
Imagine being a data analyst at a retail chain in Nagpur. Your CEO walks into the office and asks:
“Which products drove revenue during the festive season, and which regions underperformed?”
Raw numbers are overwhelming. Excel pivot tables and Power BI dashboards help, but Tableau excels in storytelling. It transforms complex data into interactive visual reports that engage executives and stakeholders, making insights easier to grasp.
At curiositytech.in, learners practice Tableau through real-world projects, analyzing sales, marketing campaigns, and customer trends, gaining the confidence to create reports that tell a story.
Step 1: Setting Up Tableau
- Install Tableau Desktop (trial version or licensed)
- Open Tableau and connect to data sources:
- Excel files
- CSV files
- SQL databases
- Google Sheets
- Excel files
- Preview data and check for consistency
Example: Connect a retail sales Excel dataset containing Product, Region, Sales, and Order Date.
Step 2: Creating Worksheets
- Drag and drop fields to Rows and Columns
- Use Measures for numeric values (e.g., Revenue, Quantity)
- Use Dimensions for categories (e.g., Product, Region)
- Apply filters to focus on relevant data
- Customize colors, labels, and tooltips to improve clarity
Step 3: Using Calculated Fields
Calculated fields allow dynamic metrics for reporting:
- Profit Margin:
[Profit] / [Revenue]
- High Sales Indicator:
IF [Revenue] > 50000 THEN “High” ELSE “Low” END
- Weekday Extraction:
DATENAME(‘weekday’, [Order Date])
Step 4: Building Dashboards
Scenario: Nagpur retail chain wants an executive dashboard:
- Create multiple worksheets:
- Bar chart for revenue by product
- Line chart for weekly revenue trend
- Map showing revenue by region
- KPI cards for total sales and top products
- Bar chart for revenue by product
- Combine worksheets into a dashboard
- Add filters and interactive elements
- Adjust layout for executive readability
