Abstract

PLT is a computer graphics program aimed at easing the task of preparing two-dimensional line graphs, bar charts and other diagrams for scientific publications and presentations. PLT offers several advantages over large statistical packages with incorporated graphics capabilities: it is fully interactive, very fast and quite simple to use. It provides great flexibility in the development of publication-quality illustrations with mixed line and bar graphs, multiple figures, regression analysis, and more. PLT allows complete control over the graph's shape, axes, ticmarks, line and symbol types, bar shadings and font styles. PLT possesses many of the attributes which make microcomputer graphics popular: extensive on-screen drawing and lettering capabilities, interaction through the keyboard, mouse or digitizing tablet, progressive development of illustrations, on-line help, etc. PLT is a FORTRAN-77 program. At this point, it is designed to run on VAX computers under the VMS operating system with graphic terminals and printers compatible with standard TEKTRONIX-4014 technology (such as VT/240-compatible devices). PLT can also be used on microcomputers connected to a VAX through VT/240-emulator software. PLT can also be used to complete illustrations prepared with TEKTRONIX-4014 protocol by other software such as SAS or MINITAB.
