This study investigates whether pixel graphs more accurately represent percentage based data than pie graphs or bar graphs. Participants were asked to answer 24 questions each pertaining to a different graphical stimulus. Results suggest that pixel graphs are significantly better at representing large quantities of percentage based data than pie graphs.
