Operating on saved X–Y data objects

You can derive new X–Y data by operating on previously saved X–Y data objects. This section discusses how to operate on X–Y data and presents each of the possible operations you can perform.

You can also operate on history data during the save procedure. For more information, see Saving an X–Y data object.
