Spreadsheets, charting and graphing programs


Spreadsheets are intended primarily for manipulating and correlating sets of
figures. Most, however, also include the facility to produce charts and graphs
summarising numerical data. These range from simple bar and pie charts to
quite sophisticated three dimensional colour graphs. Examples of popular
products include Microsoft Excel (Macintosh/Windows), Lotus 123
(DOS/Windows/Macintosh) and Quatro Pro (DOS)(see Byte march 1992 at p222 for a
comparative review). Programs designed for charting and graphing programs
usually offer more sophisticated results then are available from most
spreadsheets. Examples include: CA-Cricket Graph (Macintosh/Windows),
Deltagraph Professional (Macintosh) and GraphMaster (Macintosh).

Slide Shows


Programs such as Harvard Graphics (DOS/Windows)prepare static images (like the
programs mentioned above) but allow them to be displayed in sequence as a
'slide show' on a computer screen or overhead projection.


Interactive Graphics


'Interactive graphics' refers to graphics which allow the user to manipulate
them interactively, examples of which include HyperCard (Macintosh), ToolBook
(Windows) and Spinnaker Plus (Macintosh/Windows).
