Human-Computer Interaction
Summary
People often look at line charts quickly, and the titles can change what patterns they notice in the data. The authors studied how the number of words and the message in chart titles changed what viewers thought the pattern was. They found both factors really do shape how people identify trends in the charts. This means the way titles are written is important for clear data stories.
What this means in practice

Abstract
Visual data communication in digital media is increasingly characterized by short attention spans and snapshot-based viewing, often employing line charts to convey trends and patterns. Among all visual elements, titles are crucial ones that can shape how viewers interpret visual information and form chart takeaways. In this study, we examine how title characteristics, particularly title word count and intended message, influence people's pattern identification in single-class line charts. Participants viewed 50 line charts collected from online news media and identified the pattern they perceived. Our results demonstrate that both title word count and intended message significantly influence viewers' pattern identification. Our findings highlight the importance of title design in shaping chart takeaways and effective visualization communication.
