dislin_test
Tests for the dislin plotting package

dislin_test, C++ programs which test the DISLIN scientific plotting package.

The graphics output from DISLIN can go to into a standard graphics file, or an interactive X Window screen, or into a generic DISLIN graphics metafile, for later processsing. The standard graphics file formats that DISLIN recognizes include:

• CGM, a Computer Graphics Metafile;
• GKSL, a GKSLIN metafile.
• PS, a PostScript file;
• EPS, an Encapsulated PostScript file;
• PDF, a PDF file;
• HPGL, a Hewlett-Packard Graphics Language file;
• WMF, a Microsoft Windows Metafile;
• SVG, a Scalable Vector Graphics file;
• GIF, a Graphics Interchange File;
• TIFF, a Tagged Image File Format file;
• PNG, a Portable Network Graphics file;
• PPM, a Portable Pixel Map file;
• BMP, a Microsoft Bit Map file;
• an IMAGE file;
• Tektronix, X Window, and VGA display format;
• a DISLIN MET file, the DISLIN "metafile" format, which can be converted later to any of the other formats;

When creating a graphics output file, please note that DISLIN will not overwrite an existing graphics file. Instead, it will store the new information in a file with the right extension, but a different "first name" than you specified. For example, if you run the first example, it will create the file "dislin_ex01.png". If you rerun the first example, the output will go into a file which DISLIN arbitrarily names "dislin_1.png". To override this behavior, you must call the filmod routine passing in the string "DELETE" first.

To use DISLIN, you must access the correct include file, DISLIN library file, and associated X libraries. The shell scripts that run the examples have been set up to take care of these steps at compile and load time. If you plan to use DISLIN, you will need to pay attention to the installation instructions so that you set up your environment correctly!

DISLIN Levels

DISLIN is a plotting library, designed so that you can be generating data and creating plots at the same time. This necessarily means that you use the program by making many subroutine calls, to define the plot type, the plot size, the axis length, and so on. The examples below are one way to familiarize yourself with this procedure, and the manual has extensive explanations of how to make the plot you want.

If might be helpful, though, to note one feature of DISLIN, (which it shares with related plotting libraries such as the old DISSPLA library). The plotting library starts out at "level 0". Calling an initialization routine moves you to "level 1", at which point graphs can be defined. Defining a graph moves you to level 2, at which point you can also define features associated with the graph, such as axes. When you read the manual, you will see that some plotting routines are only allowed to be called when the plotting library has reached a specific level.

Languages:

DISLIN examples are available in a C version and a C++ version and a FORTRAN90 version.

Related Programs and Data:

GNUPLOT, C++ programs which illustrate how a program can write data and command files so that gnuplot can create plots of the program results.

GRAPHICS_EXAMPLES, C++ programs which illustrate how various kinds of data can be displayed and analyzed graphically.

MET, a data directory of examples of MET files, a graphics file format used by the DISLIN plotting package of Helmut Michels.
