Hello, I spent a lot of time debugging numerical codes. Very often, it is useful to plot a certain quantity instead of staring on numbers. To help with this, I wrote some small user defined commands to create a plot with gnuplot during the debugging session. Perhaps, you want to include it in your distribution, I attach you the file. (I know, DDD has this functionality, but perhaps CLI or Emacs users might be interested in this.) Best regards, Florian
