The interactive graphics in SPSS can be accessed from the menu by choosing graphs:interactive. It enables the availability of a greater range of graphics than are present using older, non-interactive graph options. An example is given below in SPSS syntax for one such enhancement: clustered boxplots. Further editing of the graph may be performed by clicking on particular parts of the outputted graph.
A comprehensive list of examples illustrating the capabilities of interactive graphics in SPSS, with implementation details, is available in a downloadable pdf file at http://www.siue.edu/IUR/SPSS/SPSS%20Interactive%20Graphics%2010.0.pdf
