Select File - Save to save the presently displayed plot to a graph file. The default file name is the base name of the first project displayed with the extension .sgrx. The first time you save a plot, a browse window appears which allows you to name the graph file. To save a graph file under another name, use the File - Save As command. To open a graph file, use the File - New Graph or File - Add to Graph command. Note that the graph file only contains information on what is plotted but does not include the project files with the analysis results. When you open the graph file, the referenced projects must be present in the same relative path.
