More Metrics on a Graph

Through discovery interviews, I learned that brand managers often needed to track 3–5 metrics simultaneously to understand campaign performance and make optimization decisions. For example, comparing ROAS, spend, and organic sales together revealed insights that weren’t visible in a two-metric view. I explored multiple interaction patterns for adding and removing metrics, balancing flexibility with clarity. Key challenges included preventing visual clutter, ensuring graphs remained readable, and aligning with existing design system constraints. My role included: - User Research – uncovering real-world use cases for multi-metric analysis. - Interaction Design – designing flows for selecting, customizing, and toggling between metrics. - Data Visualization – simplifying how multiple lines could be displayed without overwhelming users. - Prototyping & Testing – validating usability with brand managers and refining designs to improve readability. - Cross-functional Collaboration – working with engineers to ensure performance and scalability when rendering multiple data streams.
