title: Percentage scattergram to depict changes in large amounts of data over time.
abstract: Graphical representation of changes in epidemiologic or clinical parameters over time is difficult when a large amount of data is involved. The traditional methods either cannot incorporate all necessary information (bar graphs, pie charts, tables) or are unable to depict information on more than a limited number of individuals (scattergrams). We have designed an effective way of visual presentation of the changes a variable demonstrates over time. The percentage scattergram provides accurate and complete depiction of any number of data points, allowing comprehensive and rapid analysis.
