Charts are saved and restored as two items:

DATA
FORMAT

When you save a chart and when you load it you have the choice of saving either the data or the format or both. You can make use of this to save yourself time and your computer storage space as shown on the opposite page.

You can also save a "picture" of your chart as a set of computer drawing instructions. This is called a Graphics Data Format (GDF) file. You cannot edit GDF files but you can display or print them or pass them to other programs to display or print.

You can print a GDF chart by using the PR command from the directory panel. (There is more on GDF in Appendix D, How to become the local expert)

Figure 84. Charts are either saved in two parts or as a GDF file
