Graphical Summery of Patient Status

In medicine, large amounts of information are generated and have to be processed mostly by humans. Graphical representations help to make this myriad of information graspable and are
a crucial part in the workflow of healthcare personnel. These representations range from Fever Curves of the nineteenth century and EEG Time-Series Plots of patient status by Edward R. Tufte and Seth M. Powsner [Powsner and Tufte, 1994] makes use of concepts like smal l multiples, focus+context, or the integration of textual and graphical information. It manages to display information on a single page that normally fills up entire file folders and would require serious effort to summarize it.

E.J. Marey's Train Schedule

A very remarkable representation of time-oriented information was created by Etienne-Jules Marey in the 1880s. It shows the train schedule for the track Paris to Lyon graphically. Basically, a 2D diagram is used placing the individual train stops according to their distance in a list on the vertical axis and time on the horizontal axis. Thus, horizontal lines are used to identify the individual stops and a vertical raster is used for timing information. The individual trains are represented by diagonal lines running from top left to bottom right (Paris - Lyon) and bottom left to top right (Lyon - Paris) respectively. The slope of the line gives information about the speed of the train – the steeper the line, the faster the respective train is travelling. Moreover, horizontal sections of the trains’ lines indicate if the train stops at the respective station at all and how long the train stops. On top of that, the density of the lines provides information about the frequency of trains over time. This leads to a clear and powerful representation showing complex information at a glance while allowing for in-depth analysis of the data. Similar representations have also been used for the Japanese Shinkansen train and in Java (Soeraba ja-Djokjakarta train line) where the track’s terrain profile is additionally shown.

Gantt Chart

Especially the field of project management deals with planning activities, people, and resources. Lots of applications exist that support project management on computers. The best known technique for that matter are Gantt Charts. Mainly work tasks with their temporal parameters’ location and duration as well as milestones are depicted. The tasks are displayed as a list in the left part of the diagram and related tasks can be grouped to form a hierarchy. For displaying the extent of tasks in time, horizontal bars (Timelines) are used, that are drawn at the respective lines of the task list. This leads to an easily comprehensible representation of information in the past, present, and future. Hierarchically grouped tasks can be expanded and collapsed interactively to ensure the overview of larger plans.
