Exemplar figure, described by caption below — This figure shows the percentage of takeaways mentioning primary or secondary features in single and multi-line charts when captions vary in two perspectives: the captioned feature and the semantic level. In the upper-left quadrant, the green bars are higher than the yellow bars, indicating statistical level captions highlight primary features in single-line charts more effectively. In the other three quadrants, especially the lower two quadrants, the yellow bars are higher than the green bars. This result shows that perceptual level captions increase the memorability of medium or low salience features, such as primary and secondary features in multi-line charts.
