Chapter 1PrefaceAbstractGLE (Graphics Layout Engine) is a graphics scripting language designed for creating publication qualitygraphs, plots, diagrams, figures and slides. GLE supports various graph types (function plots, histograms,bar graphs, scatter plots, contour lines, color maps, surface plots, ...) through a simple but flexible set ofgraphing commands. More complex output can be created by relying on GLE’s scripting language, whichis full featured with subroutines, variables, and logic control. GLE relies on L A TEX for text output andsupports mathematical formulea in graphs and figures. GLE’s output formats include EPS, PS, PDF,JPEG, and PNG. GLE is licenced under the BSD license. QGLE, the GLE user interface, is licencedunder the GPL license.Trademark AcknowledgementsThe following trademarks are used in this manual.Windows Microsoft Corporation.TEX Donald E.
