Graphical Data

The display of data in graphical form - and I use the term in its strictly mathematical, rather than computer, sense - is the most common form of presenting data visually. Instant Graph Plotter is a program that does just that, but it is much more than its title suggests.

Once the basic data is entered, guided by on-screen prompts, the graph is drawn on the hi-res screen, either on its own, or in conjunction with other graphs held by the computer. Space doesn't permit mentioning the many control functions in full, but some of the main features are: addition, deletion or change of individual points, superimposition of grids, axis markers and lines and calculation of the area under the curve.

The graph can be instantaneously redrawn in logarithmic form, or with data convertedto a power, root, reciprocal, or other multiplication factor.

If all this seems a little daunting, the package is amply supported by a 27-page manual, and half an hour spent with this, and using the excellent on-screen prompts, will make its use simplicity itself. Apart from its educational value, Instant Graph Plotter is useful in displaying graphic data, and would be handy for sales conferences, science fairs and exhibitions.

Written in Basic, it is readily accessible for modification, although as it stands, there is little memory left to spare on a 32K machine. Users with particular problems are invited to contact the suppliers, R&P International, for help.
