2.2.6-18 Plotting Stored Data

Automated plotting of computer-stored data should be provided at user request, with provision for subsequent editing by a user.

Additional Information:
In many applications, data intended for graphic display will already be stored in the computer. In such cases, a user might specify the graphic format required (e.g., a line graph, or, for three-dimensional data, an XYZ plot), and edit elements in the resulting display output, without actually having to re-enter the data. When users do have to enter data for graphic display, they might choose form filling or tabular entry for efficiency in the initial input of data and then invoke graphic capabilities for subsequent data editing. In either case, it is important that previously entered data should be accessible for graphic processing.
