Curve-plotting Graphics

Curve-plotting has many applications. For example, an oscilloscope is a curve-plotting device which allows the user to view time-varying voltages. This article presents a program which allows the Timex/Sinclair computers to be used as curve-plotting devices. The common representations of curves possible with this program include the following: Cartesian, Cartesian Parametric, polar, and polar parametric. An example of a polar plot would be the radiation pattern of an antenna. The program requires the 8K ROM and makes use of pixel graphics.
