Introduction to gnuplot

GNUPLOT is a nice free software which displays various mathematical functions and numerical data. There are many Web ites and documents those explain how to make a plot of functions, so here I describe how to make a figure of numerical data such as experimental data or results of numerical calculations.

Basic Use - from start to the end

Use for a Numerical Calculation - Plots of Calculated Results

Use for Experimental Data - Plots of Experimental Data

Plot Functions and the Least-Squares fitting to experimental data
