DISLIN is a high-level library of subroutines and functions that display data graphically. It is intended to be a powerful and easy to use software package for programmers and scientists that does not require knowledge of hardware features. The software is available for the programming languages C Fortran 77 Fortran 90 Perl Python and Java. DISLIN can display graphic information directly on graphic terminals or store them in metafiles. The supported display types are VGA X Windows Windows API and Tektronix. The supported file formats are GKSLIN CGM HPGL PostScript PDF SVG WMF PNG and TIFF. The library contains the following features: - 9 software fonts where each font provides 6 alphabets. Hardware fonts for PostScript printers X11 fonts for X11 displays and TrueType fonts for Windows 9598NT displays and WMF files can also be used. The different aphabets contain Roman Greek Russian mathematical and special European characters. Plotting of mathematical formulas with TeX instructions. - Plotting of two- and three-dimensional axis systems. Axes can be linearly or logarithmically scaled and labeled with linear logarithmic date time map and user-defined formats. - Plotting of curves. Several curves can appear in one axis system and can be differentiated by colour line style and pattern. Multiple axis systems can be displayed on a page. - Plotting of legends. - Elementary plot routines for lines vectors and outlined or filled regions such as rectangles circles arcs ellipses and polygons. - Shielded regions can be defined. - Business graphics. - 3-D colour graphics. - 3-D graphics. - Elementary image routines. - Geographical projections and plotting of maps. - Contouring. - Graphical user interface (GUI) routines based on Motif and Windows API functions. - Manuals are available in HTML format and as printed books.
