Evidence Notes.
8 Findings Published
Evidence
Primary referent: stacked line chart.
Evidence
Implied function: The icon must communicate Stacked Line Chart in a digital interface..
Evidence
Metaphor type: functional.
Evidence
The icon effectively represents a stacked line chart with strong perceptual clarity, scoring 0.79 in perceptual convergence, indicating good visual resilience to size, blur, and contrast changes.
Evidence
Semantic transparency and functional mapping are moderate, with semantic convergence at 0.59 and functional convergence at 0.63, reflecting some ambiguity in interpretation without contextual cues.
Evidence
Cultural convergence is the weakest axis at 0.56, showing limited widespread recognition and cultural saturation, which may cause confusion especially among users with varying familiarity or cultural backgrounds.
Evidence
The icon's neurocognitive convergence score of 0.56 suggests moderate ease of interpretation across different cognitive styles, but some users may require learned conventions to fully understand the symbol.
Evidence
Context independence is moderate (0.62), implying the icon can communicate its meaning reasonably well without external labels or placement cues, but risks remain if used alone in ambiguous contexts.
