Conventions used

There are a number of text conventions used throughout this book.

Code in text: Indicates code words in text, database table names, folder names, filenames, file extensions, pathnames, dummy URLs, user input, and Twitter handles. Here is an example: “Write \draw [blue] circle (1cm); to get a blue circle.”

A block of code is set as follows:

\begin{tikzpicture}
  \draw (-0.5,0) to ["text"] (0.5,0);
\end{tikzpicture}

When we wish to draw your attention to a particular part of a code block, the relevant lines or items are set in bold:

\begin{axis}[axis lines=center]
  \addplot {x^3/5 - x};
\end{axis}

Any command-line input or output is written as follows:

$ texdoc tikz

Bold: Indicates a new term, an important word, or words that you see onscreen. For instance, words in menus or dialog boxes appear in bold. Here is an example: “On the right-hand side, we see the so-called Transpose of the matrix.”
