Abstract

The efficiency of a graph visualizing multivariate data is not only subjectively evaluated by human visual perception but also objectively estimated by visual features of graph. For a designed graph, it is necessary to improve visual features to enable human to extract better information from data. Integrating retinal variables into graph is an approach to increasing visual features of graph. In this study, the constituents of graph are grouped into classes of marks by qualitative and quantitative characteristics. The retinal variables are studied and structured to integrate into the classes of marks. A process of five steps is proposed to increase visual features by integrating retinal variables into graph. The process is illustrated with two case studies, increasing visual features of bus space-time map with qualitative mark classes and increasing visual features of the graph representing the data of hand-foot-mouth epidemic in Binhduong with qualitative and quantitative mark classes.
