I want to use gnuplot to draw figure from data file, say eisenhoitschule.detly, I hardcoded the data file name in the command file, say eisenhoitschule.de, and run command gnuplot eisenhoitschule.de to plot data. However, I want to pass the data file name as a command argument, e.g. running command gnuplot eisenhoitschule.de eisenhoitschule.de to parse the command line arguments in gnuplot script file?

This tutorial is intended as a supplement to the information contained on the Physics' Department website: Plotting and Fitting Data and Plotting Data with Kaleidagraph. It shows how to perform the same functions described in those tutorials using gnuplot, a command-line-driven plotting program commonly available on Unix machines though available for other platforms as well. You may find it helpful to look at the other tutorials as well; this one is intended to follow them quite closely. The instructions and samples given correspond to version 3.
