The image below was created with replot, which is a tool I wrote for my thesis. It converts output from an integration of a PDE into a time evolution diagram. It can accept complex-valued input, producing colour output to indicate phase.
Originally I wrote a command-line only version, which outputs PostScript.Download source code(18k)
I then upgraded this to enable X11 viewing of the results before printing, and I've recently tweaked it to get it working on more platforms (Linux 2.2, IRIX 6.5, HP-UX 11, Solaris 2.6 & 2.7, AIX 4.3.2). Download source code (20k) Download test file (250k)
Still, if this tool is of use to you, feel free to download it and use it. The code is freely redistributable provided that my copyright notice remains intact in the code. No warranties, of course.
This tool was also used to produce the image on the yellow t-shirt displayed here (and in close-up here)
