🤠 Join our community! https://www.skool.com/learn-power-app... ⬅️ Are you ready to tackle advanced data shaping and charting in Power Apps? In this deep-dive session, we’ll take normalized data and transform it into robust, visual reports—without ever compromising the integrity of your underlying data. Watch as we:

Create Complex Joins & Denormalized Collections
Learn how to preserve your original data structure while building powerful “join” tables in memory, perfect for on-the-fly analytics.

Calculate Averages, Medians, and Mode Ranges
Explore multi-step formulas to compute critical statistics, including a creative way to handle ‘mode’ as a scoring range.

Transform Data for Dynamic Visuals
See how to reshape rows and columns “sideways” to feed line charts, bar charts, and pie charts that compare subjects, students, and more.

Build Interactive Dashboards
Step by step, we’ll assemble line graphs for test histories, bar charts for comprehensive test stats, and a pie chart to compare median scores among different students.

Understand the Power of Collections & ForAll
Discover how to leverage collections, advanced Patch logic, and iterative loops (ForAll) to produce flexible, memory-based data structures—perfect for custom reporting.

If you’re looking to move beyond simple Power Apps forms and want to impress stakeholders with slick, real-time analytics, this walkthrough is for you. By the end, you’ll understand how to manipulate and visualize even the trickiest datasets with ease.
