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.

This chapter is mostly concerned with ways to tell the different curves apart when multiple functions and/or datasets are plotted on a single graph. The three chief methods of accomplishing this are to plot the curves with different colors, different styles (thin, thick, dashed, dotted, and so on), or by using different types of symbols (or what gnuplot calls points). We saw examples of different line styles in the preceding chapters, and gnuplot will automatically render a series of curves in a succession of styles or colors in order to distinguish them. But now we will learn the details of how to take charge of our line styles, colors, and point styles. The printed version of this book will not let you see the full effect of manipulating color, but the electronically available versions of the graphs contain all the color and transparency information resulting from the recipes.

In addition to colors and styles, this chapter discusses setting the size of your plot, and introduces...
