Let's build a dashboard that tells a story! 🚀

1️⃣ What is a Power BI Dashboard?

A dashboard is a single-page interactive report that provides insights at a glance. Unlike reports, dashboards:

• 🔹 Are designed for decision-makers.
• 🔹 Show key metrics and KPIs.
• 🔹 Combine multiple data sources into a single view.
• 🔹 Allow real-time interactivity for users.

A well-designed dashboard makes it easy to track trends, compare data, and make informed decisions.

2️⃣ Planning Your Dashboard: Key Considerations

📌 Before creating a dashboard, ask yourself:

• ✅ Who is the audience? (Executives, sales teams, finance managers, etc.)
• ✅ What story do I want to tell? (Sales trends, customer behavior, operational performance, etc.)
• ✅ What KPIs matter? (Revenue, growth rate, conversion rates, etc.)

Example Use Case:

Imagine we are building a Sales Performance Dashboard for a retail company.

Key KPIs to include:

📌 Total Sales 📌 Sales by Region 📌 Top 5 Products 📌 Sales Trend Over Time

3️⃣ Choosing the Right Visuals for Your Dashboard

Power BI offers many visuals, but choosing the right one improves clarity and impact.

🚀 Tip: Avoid using too many Pie Charts – they can be hard to read!

4️⃣ Step-by-Step: Building an Interactive Power BI Dashboard

🔹 Step 1: Import Your Data

• 1️⃣ Open Power BI and click Home > Get Data.
• 2️⃣ Choose your data source (Excel, SQL Server, or a CSV file).
• 3️⃣ Click Load to bring the data into Power BI.

🔹 Step 2: Create Key Measures Using DAX

Instead of using raw columns, create measures for better performance.

📌 Total Sales Calculation

DAX

TotalSales = SUM(Sales[Amount])

📌 Sales Growth Rate

DAX

SalesGrowth = DIVIDE(TotalSales - CALCULATE(TotalSales, SAMEPERIODLASTYEAR(Sales[OrderDate])), CALCULATE(TotalSales, SAMEPERIODLASTYEAR(Sales[OrderDate])))

📌 Top 5 Selling Products

DAX

Top5Products = TOPN(5, SUMMARIZE(Sales, Sales[Product], "Total Sales", SUM(Sales[Amount])), [Total Sales], DESC)

🚀 Tip: Use measures instead of calculated columns for faster performance!

🔹 Step 3: Add and Format Visuals

• 1️⃣ Click Insert > Visualizations and choose a Bar Chart for Sales by Region.
• 2️⃣ Drag Region to the Axis and Total Sales to the Values field.
• 3️⃣ Click Insert > Card Visual to display Total Sales as a KPI.
• 4️⃣ Use a Line Chart to show monthly sales trends over time.
• 5️⃣ Insert a Map Visual to display Sales by Country.

🚀 Tip: Keep your visuals aligned and consistent for a clean layout!

🔹 Step 4: Add Interactivity with Slicers & Filters

• 1️⃣ Click Insert > Slicer and choose Order Date for a time filter.
• 2️⃣ Add another slicer for Product Category so users can filter data.
• 3️⃣ Go to Format > Edit Interactions to control how slicers affect visuals.

📌 Dynamic Filtering Example

Want to show only data from the last 12 months? Use this DAX filter:

DAX

Last12Months = FILTER(Sales, Sales[OrderDate] >= TODAY() - 365)

🚀 Tip: Use slicers instead of filters in visuals for a better user experience!

🔹 Step 5: Enhance User Experience with Tooltips & Drill-through

✅ Enable Tooltips

• Go to Format > Tooltip and enable it.
• Add additional details (e.g., Profit, Discounts) for better insights.

✅ Drill-through to Detailed Reports

• Right-click on a visual and select Drill-through to show more details.

🚀 Tip: Use conditional formatting to highlight important data points!

🔹 Step 6: Publish and Share Your Dashboard

• 1️⃣ Click File > Publish to Power BI Service.
• 2️⃣ Choose a workspace and upload your report.
• 3️⃣ Click Share to distribute it to stakeholders.

🚀 Tip: Set up scheduled refreshes to keep data up to date!

5️⃣ Dashboard Design Best Practices

• ✅ Keep it simple – Avoid clutter, focus on key insights.
• ✅ Use consistent colors – Make visuals easy to read.
• ✅ Limit the number of visuals – Too many can confuse users.
• ✅ Optimize performance – Use measures instead of calculated columns.
• ✅ Add context – Use titles, tooltips, and labels for clarity.

🚀 Example: Ideal Dashboard Layout

• 📌 Top Section: KPIs (Total Sales, Growth, Profit)
• 📌 Middle Section: Key Trends (Sales by Region, Monthly Growth)
• 📌 Bottom Section: Drill-through visuals (Product Breakdown, Discounts, Profit Margins)
