In this self-directed project, I developed an interactive Power BI dashboard by closely following a tutorial from The Developer on YouTube. The project aimed to deepen my expertise in DAX (Data Analysis Expressions), enabling me to create dynamic measures and perform data transformations for more advanced analysis. I also used this project to familiarize myself with Power BI’s UI customization features, applying principles from my UI/UX background to enhance the interface.
Following the tutorial closely, I recreated the visuals, calculations, and layout, adjusting the interface language to be more user-friendly for better readability. This approach allowed me to refine my DAX skills while also exploring how design practices can be implemented within Power BI.
Research & Setup
Analyzed the tutorial’s approach to DAX and dynamic measures, configured Power BI, and connected the sample dataset to begin analysis.
Design & Implementation
Followed the tutorial meticulously, replicating charts, dynamic measures, and design elements while personalizing the UI text. Focused on mastering DAX for enhanced data manipulation and learning how Power BI supports UI principles to improve user experience.
Review & Deployment
Tested the dashboard for functionality, ensuring DAX-driven features and UI adjustments worked cohesively. Conducted a final review to optimize visual consistency and usability.
In the completed dashboard, I successfully visualized key metrics and actionable insights derived from the sample data. Key features include:
Interactive Charts
Created interactive charts, including bar and line graphs, to represent data trends and comparisons effectively.
DAX-Driven Calculations
Applied DAX to develop dynamic measures that transformed and adapted data in real time, enhancing the depth of analysis and enabling more responsive insights.
UI Customization
Leveraged my UI/UX experience to adapt labels and interface elements for a more intuitive user experience.
Visual Consistency
Maintained a cohesive design with a customized theme, balancing readability with a polished look that aligns with best practices in data visualization.
