| Visualizing Operations on Temporal Data (1989) | |||||||||||||
Abstract | |||||||||||||
| this paper, we focus on the interaction component of the visualization task by formalizing the operations that can occur in the interactive display of temporal data. Our formalization is based on the notion of the time line. Formally, a time line is defined as a tuple ! E; e 0 ; e n ; M ? where E is non-empty set of events, beginning with event e 0 2 E and ending with event e n 2 E, and M is a measure function M : E ! R | |||||||||||||
