βœ… Power BI Basics: Part-5 – Calculated Columns vs Measures πŸ“Šβš–οΈ

πŸ“˜ 1️⃣ What is a Calculated Column?
A calculated column is created row by row in your table. It's stored like any other column and calculated when data is loaded.

Example:
Profit = Sales[Amount] - Sales[Cost]
Used when you need to group, sort, or filter using the new column.

βœ… Best when:
β€’ You need new data fields
β€’ Used in visuals that need row context
β€’ Required for slicers or categories

πŸ“˜ 2️⃣ What is a Measure?
A measure is calculated on the fly when used in a visual. It depends on the filters and context applied.

Example:
Total Profit = SUM(Sales[Profit])

βœ… Best when:
β€’ You want dynamic calculations
β€’ Data should change with filters
β€’ Ideal for KPIs, dashboards

πŸ“Œ Key Differences:
β€’ Columns = Static, stored per row
β€’ Measures = Dynamic, context-sensitive
β€’ Columns take more memory
β€’ Measures are faster and more efficient

πŸ’‘ Rule of Thumb:
Use calculated columns only if you must. Prefer measures for performance and flexibility.

🎯 Practice Task:
β€’ Create a calculated column for Profit Margin
β€’ Create a measure for Total Sales
β€’ Use both in a bar chart and see the difference

βœ… Power BI Basics: Part-6 – Core Visualizations πŸ“ŠπŸ“ˆ

πŸ“˜ 1️⃣ Bar Chart
β€’ Great for comparing categories
β€’ Example: Sales by Region
β†’ Drag Region to Axis, Sales to Values

πŸ“˜ 2️⃣ Column Chart
β€’ Vertical bars – ideal for trends or comparisons
β€’ Example: Revenue per Month

πŸ“˜ 3️⃣ Line Chart
β€’ Best for showing trends over time
β€’ Example: Daily website traffic
β†’ Drag Date to Axis, Visitors to Values

πŸ“˜ 4️⃣ Pie/Donut Chart
β€’ Shows parts of a whole
β€’ Example: Sales % by Product Category
β†’ Avoid using for more than 5–6 categories

β€’ Displays raw data in tabular format
β€’ Add multiple fields – good for detailed reports
β†’ Supports sorting and conditional formatting

πŸ“˜ 6️⃣ Card Visual
β€’ Displays a single number
β€’ Example: Total Revenue, Total Customers
β†’ Use for KPIs

πŸ“˜ 7️⃣ Multi-row Card
β€’ Like Card, but for multiple values
β€’ Example: Show Revenue, Profit, Units Sold together

πŸ‘‡ Use Case Examples

πŸ“˜ 1️⃣ Bar Chart – Category Comparison
Use Case: Compare product-wise sales
Example:
- Axis: Product Name
- Value: SUM(Sales)
➑️ β€œWhich product sells the most?”

πŸ“˜ 2️⃣ Column Chart – Monthly Revenue
Use Case: Show how revenue changes over months
Example:
- Axis: Month
- Value: SUM(Revenue)
➑️ β€œHow does revenue trend month to month?”

πŸ“˜ 3️⃣ Line Chart – Website Visitors Over Time
Use Case: Track performance trends
Example:
- Axis: Date
- Value: Daily Visitors
➑️ β€œIs traffic increasing or decreasing?”

πŸ“˜ 4️⃣ Pie/Donut Chart – Sales Contribution by Region
Use Case: Show sales share per region
Example:
- Legend: Region
- Values: SUM(Sales)
➑️ β€œWhich region contributes the most to total sales?”

πŸ“˜ 5️⃣ Table – Customer Order Details
Use Case: Show detailed transaction data
Example:
- Columns: Customer Name, Order ID, Order Date, Amount
➑️ β€œShow all orders placed by each customer.”

πŸ“˜ 6️⃣ Card Visual – Total KPIs
Use Case: Highlight one key metric
Example:
- Field: SUM(Profit)
➑️ β€œTotal Profit = β‚Ή8,40,000”

πŸ“˜ 7️⃣ Multi-row Card – Multiple KPIs
Use Case: Display several metrics side by side
Example:
- Fields: SUM(Sales), SUM(Profit), COUNT(Orders)
➑️ β€œQuick KPI view in one glance.”

🎯 Practice Task:
β€’ Use Bar Chart to show Sales by Category
β€’ Use Line Chart for Monthly Profit trend
β€’ Use Card to display Total Customers

πŸ’‘ Tip: Use visuals that answer real business questions, not just look pretty.
