+\section{Usage}
+The package |wheelchart| can be used by putting the following in the preamble.
+\begin{codeexample}[code only]
+\usepackage{wheelchart}
+\end{codeexample}
+The package |wheelchart| loads the package |tikz| and the \tikzname{} library |calc|.
+
+Many examples in this manual use colors which can be defined by giving |dvipsnames| as an option to |\documentclass|.
+\section{The main macro}
+\begin{command}{\wheelchart\opt{\oarg{options}}\marg{wheelchart data}}
+This command can be placed inside a |tikzpicture| environment. It draws a wheelchart with \meta{wheelchart data}. The \meta{wheelchart data} is a comma separated list. Each item in this list corresponds to one slice of the wheelchart and consists of data separated by a |/|. The precise syntax of the \meta{wheelchart data} will be explained below. The \meta{options} can be given with the keys described in Section \ref{Keys}.
+\begin{command}{\exampleforthismanual}
+To simplify the creation of examples in this manual, we define the \meta{wheelchart data} below.
+\begin{codeexample}[]
+\gdef\exampleforthismanual{%
+14/Apricot/Apricot/{A, B, C, E, K}/{north east lines}/0/0/Gray,
+40/LimeGreen/Lime/{B, C}/grid/0/15/Black,
+20/Melon/Melon/{A, C}//0.5/0/none,
+16/OliveGreen/Olive/{A, B, E, K}/dots/0/0/none,
+28/Peach/Peach/{A, B, C, E, K}/{fivepointed stars}/0/0/Lavender,
+32/Plum/Plum/{A, B, C, E, K}/bricks/0/{-15}/none,
+50/WildStrawberry/Strawberry/{B, C, E, K}//1/0/DarkOrchid%
+}
+\end{codeexample}%pattern crosshatch,checkerboard
+\end{command}
+The default wheelchart with these data is shown below.
+\begin{codeexample}[width=10cm]
+\begin{tikzpicture}
+\wheelchart{\exampleforthismanual}
+\end{tikzpicture}
+\end{codeexample}
+\end{command}
+\section{Additional macros}
+\begin{command}{\WCcount}
+This macro gives the current number of the slice in the \meta{wheelchart data}.
+\begin{codeexample}[width=10cm]
+\begin{tikzpicture}
+\wheelchart[
+ inner data=\WCcount
+]{\exampleforthismanual}
+\end{tikzpicture}
+\end{codeexample}
+\end{command}
+\begin{command}{\WCdataangle}
+This macro stores the sum of the value of the key |data angle shift| (taking into account the key |counterclockwise|) and the macro |\WCmidangle| modulo $360$.
+\end{command}
+\begin{command}{\WCmidangle}
+This macro gives the angle in degrees modulo $360$ of the middle of the current slice.
+\begin{codeexample}[width=10cm]
+\begin{tikzpicture}
+\wheelchart[
+ data angle shift=\WCvarG,
+ data style={
+ rotate=\WCdataangle,
+ draw=Magenta,
+ fill=GreenYellow,
+ anchor=west,
+ text=Gray
+ }
+]{\exampleforthismanual}
+\wheelchart[
+ data={},
+ inner data={%
+ \textbackslash WCmidangle%
+ },
+ inner data style={
+ rotate=\WCmidangle,
+ font=\ttfamily
+ },
+ slices style={fill=none}
+]{\exampleforthismanual}
+\end{tikzpicture}
+\end{codeexample}
+\end{command}
+\begin{command}{\WCperc}
+This macro displays |\WCpercentage| rounded up to the number of decimals determined by the key |perc precision| followed by a \unit{\percent} symbol.
+
+If the package |siunitx| is loaded then the following code is used. The package |siunitx| can be loaded before or after the package |wheelchart|.
+\begin{codeexample}[code only]
+\qty[round-mode=places,
+ round-precision=\pgfkeysvalueof{/wheelchart/perc precision}]{\WCpercentage}{\percent}
+\end{codeexample}
+If the package |siunitx| is not loaded then the following code is used.
+\begin{codeexample}[code only]
+\WCpercentagerounded\,\%
+\end{codeexample}
+\end{command}
+\begin{command}{\WCpercentage}
+This macro gives the percentage of the current slice where the total is computed with the values of the key |value|. Note that rounding errors can occur.
+\begin{codeexample}[]
+\begin{tikzpicture}
+\wheelchart[
+ data={\WCvarC\\\WCperc},
+ slices style={
+ /utils/exec=\pgfmathsetmacro{\WCcolornumber}{4*\WCpercentage},
+ \WCvarB!\WCcolornumber
+ }
+]{\exampleforthismanual}
+\end{tikzpicture}
+\end{codeexample}
+\end{command}
+\begin{command}{\WCpercentagerounded}
+This macro displays |\WCpercentage| rounded up to the number of decimals determined by the key |perc precision|.
+\end{command}
+\begin{command}{\WCtotalcount}
+This macro gives the total number of slices.
+\end{command}
+\begin{command}{\WCtotalnum}
+This macro gives the sum of all values of the key |value|.
+\begin{codeexample}[width=10cm]
+\begin{tikzpicture}
+\wheelchart[
+ data={\WCvarC: \WCvarA},
+ middle={%
+ \textbf{\huge Fruit}\\%
+ \WCtotalcount{} species\\%
+ \pgfmathprintnumber{\WCtotalnum}
+ pieces%
+ }
+]{\exampleforthismanual}
+\end{tikzpicture}
+\end{codeexample}
+\end{command}
+\begin{command}{\WCvarA}
+\end{command}
+\begin{command}{\WCvarB}
+\end{command}
+\begin{command}{\WCvarC}
+\end{command}
+\begin{command}{\WCvarD}

+\end{command}
+\begin{command}{\WCvarM}
+\end{command}
+\begin{command}{\WCvarN}
+\end{command}
+\begin{command}{\WCvarO}
+\end{command}
+\begin{command}{\WCvarP}

+\begin{command}{\WCvarV}
+\end{command}
+\begin{command}{\WCvarW}
+\end{command}
+\begin{command}{\WCvarX}
+\end{command}
+\begin{command}{\WCvarY}
+\end{command}
+\begin{command}{\WCvarZ}
+The \meta{wheelchart data} in the command |\wheelchart| is a comma separated list. Each item in this list corresponds to one slice of the wheelchart and consists of data separated by a |/|. These individual data are interpreted as |\WCvarA/\WCvarB/\WCvarC/...| and can be accessed within the \meta{options} of the command |\wheelchart| by the macros |\WCvarA| till |\WCvarZ| except within the keys |at|, |caption|, |caption left|, |caption left style|, |caption style|, |contour|, |counterclockwise|, |expand list|, |middle fill|, |name|, |start angle|, |start half|, |title|, |title left|, |title left style|, |title style|, |total angle| and |total count|. Thus up to 26 data can be given to each slice of the wheelchart.
+
+Initially, only |\WCvarA|, |\WCvarB| and |\WCvarC| are used for |value=\WCvarA|, |slices style=\WCvarB| and |data=\WCvarC|.

+\begin{key}{/wheelchart/at=\marg{point} (initially (0,0))}
+This key defines the center of the wheelchart.
+\end{key}
+\begin{key}{/wheelchart/caption=\marg{text}}
+This key contains the \meta{text} which will be placed below the wheelchart. The \meta{text} is placed in a node. The $x$ coordinate of this node is the $x$ coordinate of the center of the wheelchart, which is defined by the key |at|. In general, this is \emph{not} the same as the $x$ coordinate of the center of the |local bounding box| around the wheelchart. The $y$ coordinate of this node is |0.5| below the south of the |local bounding box| around the wheelchart. The style of this node is given as follows. First, the options |anchor=north,align=center| are given. Thereafter, the style of the key |caption style| is added.
+\end{key}
+\begin{key}{/wheelchart/caption left=\marg{text}}
+This key contains the \meta{text} which will be placed below left of the wheelchart. The \meta{text} is placed in a node. This node is placed |0.5| below the south west of the |local bounding box| around the wheelchart. The style of this node is given as follows. First, the options |anchor=north west,align=left| are given. Thereafter, the style of the key |caption left style| is added.
+\end{key}
+\begin{stylekey}{/wheelchart/caption left style=\marg{options} (initially \normalfont empty)}

+If this key is set then a contour with the style determined by this key will be drawn around the wheelchart.
+\end{stylekey}
+\begin{key}{/wheelchart/counterclockwise=\opt{\meta{boolean}} (default true, initially false)}
+If true, the wheelchart will be drawn counterclockwise instead of clockwise.
+\begin{codeexample}[width=10cm]

+]{\exampleforthismanual}
+\end{tikzpicture}
+\end{codeexample}
+\end{key}
+\begin{key}{/wheelchart/data=\marg{text} (initially \textbackslash WCvarC)}
+This key contains the \meta{text} which will be placed at the outside of each slice of the wheelchart. This can be suppressed by using |data={}|. The \meta{text} is placed in a node. The style of this node is given as follows. First, the anchor is set following Table \ref{tableanchorofthekeydatainthecasethatlinesextequaltozero} and Table \ref{tableanchorofthekeydatainthecasethatlinesextstrictlylargerthanzero}. Then the option |align=left| is added. Thereafter, the style of the key |data style| is added.
+\end{key}
+\begin{key}{/wheelchart/data angle shift=\marg{angle} (initially 0)}
+The contents of the key |data| is placed at the angle |\WCdataangle|, which is the sum of the value of the key |data angle shift| in degrees (taking into account the key |counterclockwise|) and the macro |\WCmidangle| modulo $360$.
+\end{key}
+\begin{key}{/wheelchart/data sep=\marg{value} (initially 0.2)}
+If |lines=0|, this key defines the distance between the wheelchart and the contents of the key |data|. If $\text{|lines|}>0$, this key defines the distance between the end of the lines and the contents of the key |data|.
+\end{key}
+\begin{stylekey}{/wheelchart/data style=\marg{options} (initially \normalfont empty)}
+This key accepts a list of keys which will be applied to the node where the contents of the key |data| is placed.
+\end{stylekey}
+\begin{key}{/wheelchart/expand list=\mchoice{false,once,true} (initially once)}
+\begin{description}
+\item[\texttt{false}] In this case, the \meta{wheelchart data} of the command |\wheelchart| will not be expanded.
+\item[\texttt{once}] In this case, the \meta{wheelchart data} of the command |\wheelchart| will be expanded once.
+\item[\texttt{true}] In this case, the \meta{wheelchart data} of the command |\wheelchart| will be fully expanded.
+\end{description}
+The following example illustrates the difference between the possible values of the key |expand list|.
+\begin{codeexample}[width=10cm,preamble={\usepackage{listofitems}}]
+\readlist*\WCcolors{
+ Dandelion,CarnationPink,
+ SpringGreen,ProcessBlue
+}
+\begin{tikzpicture}
+\def\WClistA{a,A}
+\def\WClistB{b,B}
+\def\WCdata{\WClistA,\WClistB}
+\foreach\expandlist [count=\n] in
+ {false,once,true}{
+\wheelchart[
+ at={({3.5*\n},0)},
+ data=\WCvarA,
+ expand list=\expandlist,
+ radius={0}{1},
+ slices style={\WCcolors[\WCcount]},
+ title={expand list=\\\expandlist},
+ title style={font=\ttfamily},
+ value=1
+]{\WCdata}
+}
+\end{tikzpicture}

+\begin{key}{/wheelchart/start half=\marg{angle} (default 90)}
+If this key is set then the middle of the first slice of the wheelchart is positioned at \meta{angle} in degrees.
+\end{key}
+\begin{key}{/wheelchart/title=\marg{text}}
+This key contains the \meta{text} which will be placed above the wheelchart. The \meta{text} is placed in a node. The $x$ coordinate of this node is the $x$ coordinate of the center of the wheelchart, which is defined by the key |at|. In general, this is \emph{not} the same as the $x$ coordinate of the center of the |local bounding box| around the wheelchart. The $y$ coordinate of this node is |0.5| above the north of the |local bounding box| around the wheelchart. The style of this node is given as follows. First, the options |anchor=south,align=center| are given. Thereafter, the style of the key |title style| is added.
+\end{key}
+\begin{key}{/wheelchart/title left=\marg{text}}
+This key contains the \meta{text} which will be placed above left of the wheelchart. The \meta{text} is placed in a node. This node is placed |0.5| above the north west of the |local bounding box| around the wheelchart. The style of this node is given as follows. First, the options |anchor=south west,align=left| are given. Thereafter, the style of the key |title left style| is added.
+\end{key}
+\begin{stylekey}{/wheelchart/title left style=\marg{options} (initially \normalfont empty)}
+This key accepts a list of keys which will be applied to the node where the contents of the key |title left| is placed.
+\end{stylekey}
+\begin{stylekey}{/wheelchart/title style=\marg{options} (initially \normalfont empty)}
+This key accepts a list of keys which will be applied to the node where the contents of the key |title| is placed.
+\end{stylekey}
+\begin{key}{/wheelchart/total angle=\marg{angle} (initially 360)}
+This key defines the total \meta{angle} in degrees of the wheelchart.
+\end{key}
+\begin{key}{/wheelchart/total count=\marg{number}}
+If this key is set then the number of slices of the wheelchart is determined by \meta{number}.

+This key defines the \meta{value} which corresponds to the size of each slice of the wheelchart.
+\end{key}
+\begin{key}{/wheelchart/wheel data=\marg{text}}
+This key contains the \meta{text} which will be placed on top of each slice of the wheelchart. The \meta{text} is placed in a node. The style of this node is given as follows. First, the option |align=left| is given. Thereafter, the style of the key |wheel data style| is added.
+\end{key}
+\begin{key}{/wheelchart/wheel data pos=\marg{value} (initially 0.66)}
+The radius of the polar coordinate at which the contents of the key |wheel data| is placed is given by the convex combination $\text{|wheel data pos|}\cdot\text{|outer radius|}+(1-\text{|wheel data pos|})\cdot\text{|inner radius|}$.
