EZplot: a computer program which allows easy use of a line plotter

Abstract

This technical report describes the use of a computer program (called EZPLOT) which has been written to allow easy use of a computer-driven line plotter. This program has been designed to provide a simple set of commands which have adequate facility to plot a wide range of needs, specifically those associated with the ecological studies of the US/IBP Island Ecosystems Research Program. In general, the EZPLOT commands allow the description of the physical layout of the intended plot and provide several ways of entering data points and lines. Since this procedure, including the labeling with text information, is all done by the computer and plotter, it is possible to plot data at intermediate stages or modify plots to more effectively display the information without excessive redrafting charges. The technical descriptions of the EZPLOT commands are given with examples of their use. The format of this technical report deviates from the other numbers in this series as it has been designed primarily to serve as a user's guide.
