摘　　要：Various attempts at exploiting infonnation visualization for sports have recently been reported in the literature,although it is still challenging to analyze continuous ball matches.In this paper,we propose a novel visual analytics system,called TideGrapher,to track the transition of tactile situations in a rugby match.Wth a particular focus on the side position of the ball,we designed a dedicated spatial substrate based on the spatio-temporal trajectory of the ball and provided a set of basic interactions.Quantitative analysis was strengthened by adding a new index,called initiative,to commonly used possession(ball occupation)and territory(dominance of territory).The feasibility of the proposed visual analytics system was proven empirically through application to datasets from real amateur and professional matches.
