Overview of this book

gnuplot is the world's finest technical plotting software, used by scientists, engineers, and others for many years. It is in constant development and runs on practically every operating system, and can produce output in almost any format. The quality of its 3d plots is unmatched and its ability to be incorporated into computer programs and document preparation systems is excellent. gnuplot Cookbook ñ it will help you master gnuplot. Start using gnuplot immediately to solve your problems in data analysis and presentation. Quickly find a visual example of the graph you want to make and see a complete, working script for producing it. Learn how to use the new features in gnuplot 4.4. Find clearly explained, working examples of using gnuplot with LaTeX and with your own computer programming language. You will master all the ins and outs of gnuplot through gnuplot Cookbook. You will learn to plot basic 2d to complex 3d plots, annotate from simple labels to equations, integrate from simple scripts to full documents and computer progams. You will be taught to annotate graphs with equations and symbols that match the style of the rest of your text, thus creating a seamless, professional document. You will be guided to create a web page with an interactive graph, and add graphical output to your simulation or numerical analysis program. Start using all of gnuplot's simple to complex features to suit your needs, without studying its 200 page manual through this Cookbook.

Using gnuplot within LaTeX

In a previous recipe, we learned how to generate TikZ drawing commands from within gnuplot for inclusion in a LaTeX file. This recipe is, in a way, the reverse. We are going to learn how to generate gnuplot commands from within a LaTeX document.

The method introduced in this recipe is most useful when we want to enfold graphical elements into our typeset text rather than include them in floating figure environments. It also has the advantage of encompassing all the typesetting and drawing commands into a single file that is processed with one command, with no need to keep track of plot files and separate gnuplot scripts. This makes it simpler for your document source to become self-documenting and easily modifiable.

This is a flexible and powerful technique that allows us to combine plots generated by gnuplot with TikZ drawing commands. If we become proficient in TikZ, we will be able to arrange gnuplot graphs and PGF graphics in arbitrary ways on the page. As we...
