Re: [Gnuplot-info] command line arguments to gnuplot scripts

[SB <ste...@gm...>]

Hello Philipp,

I had a similar problem and used a slightly different way than Bernard suggested. 
It is not as elegant but there are advanced possibilities.

I wrote a script that first creates a gnuplot-script-file (plotfile.gnu)
and then calles gnuplot to open it. 
The gnuplot-script-file will look exactly like the one you asked for,
with one extra line (save "diagramm.gnu") at the end. 

The script for your problem could look similar to the following one:


#!/bin/sh
#Step 1: create file
echo set title $1 > plotfile.gnu
echo plot $1.data using (\$16 * 8):20 with linespoints notitle
>>plotfile.gnu
echo pause -1 >>plotfile.gnu
echo save \"diagramm.gnu\"
#Step 2: call gnuplot
gnuplot plotfile.gnu


When you see the plot, gnuplot is in interactive mode and you can
therefore zoom in and out, turn on/off logscale and so on.
If you liked the plot, rename the file "diagramm,gnu" and you have it
saved with the last settings for zoom and so on.

By the way, you can also teach KDE/Gnome/... to open your .data-files by
click with a script like this. You need to modify the script that it
accepts the complete filename. Then set the file associations of
KDE/Gnome/... to open .data-files with this script. 
Then you just click on your .data file in the file-browser and have it
displayed directly. 

I hope, this can be useful for you,

Schöne Grüße,

Stephan
