#### Overview of this book

LaTeX is a high-quality typesetting software and is very popular, especially among scientists. Its programming language gives you full control over every aspect of your documents, no matter how complex they are. LaTeX's huge amount of customizable templates and supporting packages cover most aspects of writing with embedded typographic expertise. With this book you will learn to leverage the capabilities of the latest document classes and explore the functionalities of the newest packages. The book starts with examples of common document types. It provides you with samples for tuning text design, using fonts, embedding images, and creating legible tables. Common document parts such as the bibliography, glossary, and index are covered, with LaTeX's modern approach.You will learn how to create excellent graphics directly within LaTeX, including diagrams and plots quickly and easily. Finally, you will discover how to use the new engines XeTeX and LuaTeX for advanced programming and calculating with LaTeX. The example-driven approach of this book is sure to increase your productivity.

# Plotting in three dimensions

Functions with two arguments can be visualized in three-dimensional plots. Getting this on paper or into a PDF is a bit more challenging. We need a projection, a view point or angle, and a depth, which means that some parts will be hidden and others in the front.

At the end of the previous recipe, we plotted the function f(x) = sin(x). Now, when we add a dimension, we will plot f(x,y) = sin(x)*sin(y).

## How to do it...

Like in the previous recipe, we will use the pgfplots package. Follow these steps:

1. Start with a document class. Like in the previous recipe, we use the standalone class. But it's fine if you choose the article class instead.
\documentclass[border=10pt]{standalone}
2. Load the pgfplots package:
\usepackage{pgfplots}
3. Start the document, and open a tikzpicture environment:
\begin{document}
\begin{tikzpicture}
4. Begin an axis environment with options:
    \begin{axis} [
title = {$f(x,y) = \sin(x)\sin(y)$},
xtick = {0,90,...,360},
ytick = {90...
