I have been using Gnuplot for more than twelve years, so I thought the
author could not tell me anything I did not know. I was completely
wrong. As it turned out, I did not know how to use color palettes
efficiently to visualize a structure in complex data.

Gnuplot became the tool of choice for many scientists and engineers.
It combines a powerful language, an intuitive and simple command
interface, publication quality graphics and the ability to quickly
generate many different plots for data exploration. It is free and
easily integrated with other programs (LaTeX, Octave, Maxima to name a
few). This book is a long awaited "Gnuplot bible" - a must for
anybody seriously working with numerical data. It is very well
written, the examples are carefully chosen and explained. It is
nicely typeset. The book is a pleasure to read or browse, which
becomes progressively rare for technical literature.

The book does not require a pre-existing knowledge of Gnuplot, and can
be used as a textbook for self-teaching or maybe as a part of a course
of data analysis and visualization. Nevertheless, it contains many
tips and tricks interesting not only for a novice, but also for a
seasoned user.

The book also contains a treatise on data graphing "in general", not
related specifically to Gnuplot. The principles discussed there are
sound, and could be of a general interest.

Gnuplot is a small program that I always find on unix systems I work with. Every now and then, I start it (mostly by accident) and then I'm unable to do anything with it. It has an interesting name, but... as someone who rarely needs to draw graphs, I never had the urge to study it at all.

When I saw Gnuplot in action, I got interested though. A whole book on this 'small' tool which I don't know anything about. So, I started reading and was amazed about the things you can do with gnuplot. It is an incredibly powerful tool for drawing graphs and analyzing data. The book didn't cause me to suddenly draw more graphs, but I do know which tool to use and how to use it when I *do* need to analyze data.

The book consists of four different parts. The first part is called Basics and covers exactly that. It explains how to draw simple graphs and how to work with data. The second part is called Polishing and takes the basics further and shows how to draw graphs that look good.

Part three probably surprised me much -- called Advanced Gnuplot. Chapter 8 discusses how to draw 3d graphs and chapter 9 discusses how to use color in the graphs. The examples the author uses are really impressive (and luckily, the book has some color pages to show the result). Chapter 12 reminds us that gnuplot is in the spirit of unix tools and shows how to script it and how to combine it with other applications. Part four, the last part, covers graphical analysis of data.

I was positively surprised about the book. It was well written, so well that even a person who only started gnuplot by accident could understand it. And, already very early in the book is demonstrates the usefulness of gnuplot in real life.

I'm excited about Gnuplot as a graphing tool and about "Gnuplot In Action" as a guidebook on how to effectively use Gnuplot to produce the graphs I need in the work I do.

For a couple of years I used and experienced the limitations of several plotting software products. The primary limitation of the products was their inability to handle very large data sets. I found Gnuplot via google, and it set me free, as far as plotting data sets of seemingly any size. My only beef with it was not with the Gnuplot product itself, but with its documentation. I found the Gnuplot docs and online help pages to be a little difficult to decipher. Then along came the book, "Gnuplot In Action". Problem solved.

This book is great.

It is thorough and covers all aspects of Gnuplot.
It is clearly written, well-organized, and easy to understand.
It will open up a world of graphing possibilities to the Gnuplot user...at least, that's what it did for me. It shed light on the little I understood about Gnuplot before reading the book, and introduced me to many additional Gnuplot capabilities I was unaware of.

Plain and simple: if you use Gnuplot and would like to understand it better, this book is for you. If you are looking for an excellent plotting tool -- one that is highly configurable and can easily handle millions of data points, then download Gnuplot and get this book. If you need to do graphical analysis and/or produce publication-quality graphs, Gnuplot is the tool for you and "Gnuplot in Action" is the book that can shed light on how to achieve those goals using Gnuplot software.

gnuplot is an extremely powerful graphing program available for most computer platforms. It can produce stunning plots (see the online gallery), but is not particularly easy to control. It's been around since the late 1980s, and doesn't feel very modern. Hence my interest in this book.

Based on a couple of weeks of use, I've found this book frustrating to use. In my opinion, it's not as well-written or easy to use as your typical O'Reilly book, for example.

* Not easy to use as a reference. I think this is because each time I look up how to do something, there's a little story and very specific example rather than a general definition and explanation.
* Goes on at length with narratives setting up the scenario that generated the plot data.
* Uses command abbreviations, whereas I think spelling them out would be more clear for a text.
* The conversational tone seems odd--the book may have benefited from more editing.

On the plus side, the book does have a good index (helpful for reference) and seems to cover all the major features of the software.

Overall, I would recommend this book if you're the type to learn more from a book than finding all the information online. It's one of the few books on gnuplot. It's just that it could be better with stronger editing.
