This is an updated version of an article I originally posted in German (change language with the little flags in the upper right). After posting a lot of charts and chart snippets lately, I thought I could share some ideas (and code :)) with whoever is interested in Gnuplot. When I made the initial design/architecture of my (future) trading system framework, I added a charting component to my wishlist. Not because I needed it for the actual trading, but for debugging the signal generation part (and of course enhance my signal posts on this blog with some visuals).
Almost instantly Gnuplot came to my mind, a scientific plotting utility with scripting capabilities. The best part: it is free and open source software, free as in free speech AND free beer! :) And of course, to conclude the teaser with shameless name-dropping: picking up a code snipped John Bollinger posted more than 11 years ago! So I spend a couple of evenings with Gnuplot, googling and playing around...
