\title{Drawing Pie Chart by using \texttt{pgf-pie}}

\begin{abstract}
\texttt{pgf-pie} is a LaTeX package for drawing pie chart (and
variant charts). 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{https://github.com/pgf-tikz/pgf-pie}{https://github.com/pgf-tikz/pgf-pie}.
\end{abstract}
\tableofcontents
\section{Usage}
\subsection{First Pie}
\lstinline|\pie| is the only coomand that provided by
\texttt{pgf-pie}. The argument is a list of number and text
combination in the formate of \texttt{number/text}, i.e. \texttt{10/A,
20/B, 30/C, 40/D}. The result is shown in figure \ref{fig:first-pie}.
\begin{figure}
\centering
\demo[0.6]{first-pie}
\caption{The first pie.}
\label{fig:first-pie}
\end{figure}
\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{Color}
The color can be specified by \texttt{color}, the default color wheel
is shown in figure \ref{fig:color-wheel}.
\begin{figure}
\centering
\input{demo/colorwheel}
\caption{Default color wheel}
\label{fig:color-wheel}
\end{figure}
\demo{color}
\subsection{Explode}
\demo{explode}
\subsection{Angle of slices}
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. Then the angle of slices are determined by
number value and \texttt{sum}.
\demo{sum}
\subsection{Text}
\subsubsection{Number}
Two parameters can be used to decorate number: \texttt{before number}
and \texttt{after number}. Both are empty by default, but if
\texttt{sum=100}, \texttt{after number} will be set to \%
automatically if user doesn't set it.
\demo[0.6]{before-after-number}
The number also can be hide by \texttt{hide number}:
\demo[0.6]{hide-number}
\paragraph{Scale font}
The size of font in size pie can be scaled according to how big the
part is automatically.
\demo[0.6]{scalefont}
\subsubsection{Label text}
The value of \texttt{text} can be \texttt{label}(default),
\texttt{pin}, \texttt{inside} or \texttt{legend}.
\demo[0.6]{text}
\demo[0.5]{text-inside}
\demo[0.6]{legend}
\subsection{More about style}
\subsubsection{shadow}
\demo[0.6]{shadow}
\section{Variant Charts}
\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{Square}
\demo[0.6]{square}
Note: \texttt{explode} has no affects in sqaure chart.
\subsection{Clouds}
\demo[0.6]{cloud}
\section{Examples}
% \subsection{Population of the world}
% \example{population}
