\newcommand{\pkgName}{\texttt{harveyballs}\xspace}

\begin{abstract}
This document exemplifies the \pkgName package for \LaTeXe in a nutshell. Harvey balls can be used in arbitrary contexts such as to present survey results in a visual manner or express parameter values of certain characteristics. They provide a visual means to easily compare these values best facilitated by the sophisticated pattern recognition techniques of build in visual human cognition by mother nature.
\end{abstract}

\section{Package Dependencies}

The \pkgName package requires the \texttt{tikz} package.


\section{Examples and Options}

\subsection{In text}

This is a normal text with Harvey Balls included.
Here is a value commonly indicating a property is not fulfilled \harveyBallNone.
For partially fulfilled properties you could use a Harvey Ball filled by a quarter, e.g.\,\harveyBallQuarter.
If it is half fulfilled, you could use \harveyBallHalf.
Almost fulfilled properties could be illustrated with \harveyBallThreeQuarter.
Finally, if a certain property is fullfilled entirely you should use \harveyBallFull.

\subsection{In table}
Harvey Balls can also be integrated in tables (cf.\,Table \ref{tab:ExampleForATableIncludingHarveyBalls}).


\begin{table}[h]
	\centering
		\begin{tabular}{lccc}
\hline
									&amp; Approach 1 &amp; Approach 2 &amp; Approach 3\\
\hline
			Property 1	&amp; \harveyBallNone &amp; \harveyBallQuarter &amp; \harveyBallHalf \\
			Property 2	&amp; \harveyBallHalf &amp; \harveyBallThreeQuarter &amp; \harveyBallFull \\
			Property 3	&amp; \harveyBallFull &amp; \harveyBallThreeQuarter &amp; \harveyBallQuarter\\
\hline			
		\end{tabular}
	\caption{Example for a table including Harvey Balls}
	\label{tab:ExampleForATableIncludingHarveyBalls}
\end{table}

\subsection{Custom size}

There are two variables available to the user to override the size of the Harvey Balls globally.
\begin{itemize}
\item \verb|\harveyBallsSize|, i.e. the size of the Harvey Balls and
\item \verb|\harveyBallsLineWidth|, i.e. the line width used to draw the Harvey Balls.
\end{itemize}
Threse values can be changed using the following commands:
\begin{itemize}
\item \verb|\def\harveyBallsSize{0.85ex}|
\item \verb|\def\harveyBallsLineWidth{0.2pt}|
\end{itemize}
Whereas 0.85ex and 0.2pt would be parameters, i.e. your custom sizes. Note that these are also the default values.
\verb|\def\harveyBallsLineWidth{1pt}| and \verb|\def\harveyBallsSize{3ex}| produces:\\
\def\harveyBallsLineWidth{1pt}\def\harveyBallsSize{3ex}
\harveyBallNone, \harveyBallNone, \harveyBallQuarter,  \harveyBallHalf, \harveyBallThreeQuarter, \harveyBallFull. \\ 

%reset to defaults
%\def\harveyBallsSize{0.85ex}
%\def\harveyBallsLineWidth{0.2pt}


You can also use custom sized using an optional parameter for each Harvey Ball\\

\begin{tabular}{lc}
\hline
Command &amp; {Produced Harvey Ball}\\
\hline
\verb|\harveyBallNone[14pt]| &amp; \harveyBallNone[14pt] \\
\verb|\harveyBallQuarter[14pt]|&amp; \harveyBallQuarter[14pt]\\
\verb|\harveyBallHalf[14pt]|&amp; \harveyBallHalf[14pt]\\
\verb|\harveyBallThreeQuarter[14pt]|&amp; \harveyBallThreeQuarter[14pt]\\
\verb|\harveyBallFull[14pt]|&amp; \harveyBallFull[14pt]\\
\hline
\end{tabular}
	\caption{Example for custom-sized Harvey Balls}
\end{table}

\subsection{Custom Colors}
The colors of the Havey Balls can be overridden utilizing the user variables
\begin{itemize}
\item  \verb|\harveyBallsColor|, i.e. the fill color of the Harvey Ball and
\item  \verb|\harveyBallsLineColor|, i.e. the border color of the Harvey Ball.
\end{itemize}
For instance with \verb|\def\harveyBallsColor{red}| and \verb|\def\harveyBallsLineColor{blue}| you Harvey Balls will apear like this:\\
\def\harveyBallsColor{red}
\def\harveyBallsLineColor{blue}
\harveyBallNone, \harveyBallQuarter,  \harveyBallHalf, \harveyBallThreeQuarter, \harveyBallFull. \\ 

\def\harveyBallsColor{blue}
