Alexander's and Johannes' graphics library

Last updated: February 11, 2005

Description

We have developed a graphics library and Graphical User Interface for scientific applications written in C and utilizing the X-windows interface. It is usefull for anyone wanting to steer simulations written in C on Unix (or Linux) computers. Please read the more detailed description of the library at http://www.physics.ndsu.nodak.edu/wagner/Documentation or download the same information as a pdf file.

Download:

We make this software available as free software under the GNU public license. To install the library in your home directory download graph.tar.gz and execute
tar xzvf graph.tar.gz
cd c/newgraph
make install
You can find a documentation here.

Useful programs:

The following are useful programs which use my graphics library. You are welcome to download them:

Makefile	A small general makefile that will compile a program that needs the graphics library. If your program is called prog.c you can generate the executable prog by calling make prog.
Contour.c	A program that takes data-files as input and diplays density fields and contour plots of the data. The resulting graphics can be printed into an encapsulates PostScript file. Also requires ReadData.h, ReadData.c.
Contour_mpg.c	A program that makes a movie out of a set of data-files. Needs the mjpegtools package installed on your computer. Also requires ReadData.h, ReadData.c.

Updates:

21 October 2005:

11 February 2005:

New version (number 0.9.3). Also added the section on useful programs.

22 October 2003:

New version (number 0.9.2). Small changes. DefineGraphNxR() and related routines now take a NULL pointer as last argument when the request feature is not required.

18 September 2003:

New version (number 0.9.1) allows the user to set color ramps with DefineColorRamp() and implements user defined comments through the function SetComment(); For details check the examples in myprog.c.

19 August 2003:

New version (number 0.9) will update variables even if they are changed by the program and not the GUI. Several bugs fixed.

Feature requests/known bugs:

Better control over the comments which appear when the "comment on" feature is used. (done 0.9.1)

FAQ

These program all appear to require Linux. Can I run them on my Windows computer?
Yes! But you need some additional free software available at http://www.cygwin.com/xfree/. In particular you need to install the Xserver and the development packages.
