Evaluation of The Impact of Visual Decoration on The Memorable Effect in Big Data Visualization - The Example of Bar Chart

Abstract: In recent years, data visualization has been applied to various scenes, and the memory of data visualization has received widespread attention. Some researchers have studied this. However, the effect of visual decoration is polarized in the research community. Some researchers believe that visual decoration can improve memory effect, while others believe that visual decoration can interfere with memory. This paper takes the bar chart as an example to further evaluate the memory effect of visual decoration in visualization, and puts forward four assumptions: ① the visualization using visual decoration has better memory; ② The position of visual decoration will affect the memory effect; ③ The colour of visual decoration will affect the memory effect; ④ The visual position will affect the memory effect under the same visual decoration. The results show that assumptions 1, 2, 3 and 4 are valid, which proves that visual decoration can improve the memory of visualization, and the location, colour and type of visual decoration will affect the memory of visualization.
