Drawing a pie chart

Pie charts are popular for showing proportions. A pie chart's main characteristic is that all items usually sum up to 100 percent. They are displayed as segments of a disc.

As an example, we will use a pie chart to display the relative amount of questions about different TeX distributions.

How to do it...

We will use the pgf-pie package, which builds on TikZ and is specialized for generating pie charts. Follow these steps:

1. Start with a document class:

   \documentclass{article}
   

2. Load the pgf-pie package:

   \usepackage{pgf-pie}
   

3. Begin the document:

   \begin{document}
   

4. Begin a TikZ picture, which will be the container of the pie chart:

   \begin{tikzpicture}
   

5. Draw a pie chart using this command:

    \pie [rotate = 180]
       {62/\TeX\ Live and Mac\TeX,
        32/MiK\TeX\ and Pro\TeX t, 6/Other \TeX}
   
   

6. End the TikZ picture and the entire document:

   \end{tikzpicture}
   \end{document}
   

7. Compile and take a look at the result:

   

How it works...

The \pie command is the only user command in the pgf-pie package. The...
