The development of interactive statistical graphics in the 1980s switched graphics from a result-presenting device to an analytic tool. But what makes a statistical display interactive? Even within the statistical graphics community, usage and interpretation of the term "interactive statistical graphics" is multifarious. This paper tries to extract the basic principles of user interaction in statistical graphics. By separating data displays into four levels--frame, type, model, and sample population--it is possible to describe the different plot-data relationships. According to the graph levels that are affected by an interaction, a classification of user interactions is given.
