Two-dimensional scatter point sets are stored in 2D scatter point files. The file includes the scatter point locations and requires that functional information be defined in a separate data set file. However, multiple scatter point sets can be stored in a single file. An XY coordinate pair defines each point in a scatter point set. The format allows time variant data sets to be associated with scattered data points as well as to organize data sets by allowing the user to assign an ID to the scattered data set.
Scatter files are opened through File | Open and are saved from File | Save Scatter from the Scatter module. When scatter point files are saved, a super file is saved. The super file saves and references the scatter and data set files.
