\begin{abstract}
  \texttt{pgf-pie} is a LaTeX package for drawing pie chart. As stated
  by its name, it is based on a very popular graphic package
  \texttt{PGF/TikZ}. This document presents the usage of
  \texttt{pgf-pie} and collects some pie charts as examples.
  \texttt{pgf-pie} can be downloaded from
  \href{http://code.google.com/p/pgf-pie/}{http://code.google.com/p/pgf-pie/}.

\section{The Essentials}

\subsection{First Pie}
\demo[0.6]{first-pie}

\subsection{Polar area diagram}
The polar area diagram is similar to a usual pie chart, except sectors
are equal angles and differ rather in how far each sector extends from
the center of the circle.

\demo[0.6]{polar}

\subsection{Position, Rotation, Size}

The center of chart can be set by \texttt{pos}, default is
\texttt{\{0,0\}}. The chart can be rotated by setting \texttt{rotate}
(in degrees). The size of chart can be set by \texttt{radius}, default
is 3.

\demo{radius}

\subsection{Explode}
\demo{explode}

\subsection{Text Label}

\subsubsection{Text inside pie}
\demo[0.6]{before-after-number}

\subsubsection{Text outside pie}
The value of \texttt{text} can be \texttt{label}(default),
\texttt{pin} or \texttt{legend}.

\demo[0.6]{text}

\demo[0.6]{legend}

\subsection{Sum}
The value of \texttt{sum} indicats the sum of all data in the chart,
it is 100 by default. It can be calculated automatically when
\texttt{auto} is set.

\demo{sum}

\subsection{Color}
The color can be specified by \texttt{color}, the default color wheel
is shown in figure \ref{fig:color-wheel}.

\demo{color}


\begin{figure}
  \centering
  \input{demo/colorwheel}
  \caption{Default color wheel}
  \label{fig:color-wheel}
\end{figure}


\subsection{Style}
\subsubsection{shadow}
\demo[0.6]{shadow}
