Alexiades - UTK Gnuplot on the fly The easiest way to use Gnuplot on Unix is via scripts.

Put these files in the directory with your code (better: in a dir on your unix PATH, mine is ~/.S/ ):
      gplot   gpgp   gnuplot.sh,   gnuplot_template

The shell script gplot produces a gnuplot-script out of the datafile (and calls gpgp).
The shell script gpgp creates the plot (as .ps or .png) and displays the plot.
They must be executable: chmod   +x   gplot   gpgp

Here is how to use them:

1. To plot a (multicolumn) file, say "dat", at the unix prompt type:
   gplot dat   (it prompts you for columns, defaults: 1 , 2).
   This creates a gnuplot-script file dat.gp .
2. You can edit the dat.gp file to customize it for this plot
   (set title, xrange, yrange, other files to plot, etc).
3. Then do: gpgp dat.gp
   which gnuplots it producing "dat.ps", and displays the plot with gv.
