A chart that fills in the numbers
Article Abstract:
Flexigraphs spreadsheet software from Tree Star Inc works in the reverse of traditional spreadsheets. Instead of starting with data that is translated into a graph, the user begins with the graph and manipulates it until it looks right. The program, meanwhile, generates numbers to fit the graph. Flexigraphs, $149 for the Apple Macintosh, includes Flexpie for the creation of pie charts; Flexibar for bar graphs; Flexispread, a small spreadsheet that acts as a link between Flexigraphs and other programs; and Flexiline for line graphs. There is also a new use for outline processors, a seldom-used utility on most word-processing programs. The program can create quizzes or practice drills to use as a study aid. The question is written as a main heading, the choices will be the secondary heading and the correct answer is the tertiary heading. Headings can be uncollapsed as needed.
