A bash script to plot multiple files in old version of gnuplot
For gnuplot version older than 4.4, ‘plot for’ is not an option to plot multiple files. In order to make it work and easier, I wrote a BASH script to generate the gnuplot input for multiple file plotting. You are lucky too find this if you are still using old version of gnuplot. No need to use it for the lastest version.
