Compound graphs are needed to plot data files with multiple columns. In this post we use an example data file with columns. An x value (column #1),…

Introduction to Gnuplot (Part II)

This post is in continuation of the post Introduction to Gnuplot. Generally people want to plot data from a data file. This example uses a data file containing first 10 steps of Fibonacci series. So, on X-axis we have sequence numbers (n) and on Y-axis we have Fibonacci number that appear on that sequence number (e.g. Fibonacci number…
