\begin{abstract}
This package allows you to easily visualize shares of total amounts in the form of a bar. So basically you can convert a number like $0.735$ to \progressbar{0.735} using the command \lstinline+\progressbar{0.735}+.

Of course also a lot of customizations are possible (like this: \progressbar[emptycolor=yellow,filledcolor=red,linecolor=blue,subdivisions=4,roundnessr=0.5,tickscolor=green,tickswidth=1,ticksheight=1]{0.735}).
\end{abstract}

\noindent\progressbar[width=\textwidth,heighta=3cm,filledcolor=red,emptycolor=green,borderwidth=5pt,tickswidth=2.5pt,roundnessr=0.5,subdivisions=20]{0.55}
\begin{lstlisting}[basicstyle=\ttfamily\normalsize\mdseries]
\progressbar[width=textwidth, heighta=3cm, filledcolor=red, emptycolor=green, borderwidth=5pt, tickswidth=2.5pt, roundnessr=0.5, subdivisions=20]{0.55}
\end{lstlisting}

\section{Installation}
Make sure the file \texttt{progressbar.sty} is placed somewhere, where \LaTeX can find it. Usually that means, you simply download the package \texttt{progressbar} with the \LaTeX-package-manager of your choice.

\subsection{Dependencies}
You also have to ensure that all packages needed by \texttt{progressbar} are present (some package-managers do this for you).
The dependencies are:
\begin{itemize}
	\item calc
	\item kvsetkeys
	\item kvoptions
	\item tikz
\end{itemize}
\section{How to use \texttt{progressbar}}
\DescribeMacro{\usepackage\{progressbar\}}
\DescribeMacro{\usepackage[]\{progressbar\}}
Like any other package, to use \texttt{progressbar}, you have to load it first. You do this with
\begin{lstlisting}
\usepackage{progressbar}
\end{lstlisting}
or
\begin{lstlisting}
\usepackage[<options>]{progressbar}
\end{lstlisting}
(You can find an explanation of all options in the section \ref{options}.)

Once you have loaded \texttt{progressbar}, you can use two different commands, described in the following.
\subsection{\texttt{\textbackslash{}progressbar}}\label{commandprogressbar}
\DescribeMacro{\progressbar\{\}}
\DescribeMacro{\progressbar[]\{\}}
The command
\begin{lstlisting}
\progressbar{<number>}
\end{lstlisting}
will draw you a progressbar with the share \texttt{<number>}. For example \lstinline+\progressbar{0.666}+ gives you this \progressbar{0.666}. You would want to use only numbers in the interval $[0,1]$, although other numbers are also possible (but will look just the same as \lstinline+\progressbar{0}+ or \lstinline+\progressbar{1}+).

If you want one specific progressbar to look different than the others, use
\begin{lstlisting}
\progressbar[<options>]{<number>}
\end{lstlisting}
instead. This command is just the same as \lstinline+\progressbar{<number>}+ but allows you to manipulate the appearance of the current progressbar. So \lstinline+\progressbar[width=5cm,heightr=1,filledcolor=red,emptycolor=blue!30]{0.75}+ would look like this: \progressbar[width=5cm,heightr=1,filledcolor=red,emptycolor=blue!30]{0.75}. In this case the options are only changed locally. (You can find an explanation of all options in the section \ref{options}.)

\subsection{\texttt{\textbackslash{}progressbarchange}}
\DescribeMacro{\progressbarchange\{\}}
In principle, the command \lstinline+\progressbar{<number>}+ uses the options specified with \lstinline+\usepackage[<options>]{progressbar}+ or the default options (if an option was not specified). As described in the previous section (\ref{commandprogressbar}), you can override these options with \lstinline+\progressbar[<options>]{<number>}+. However, if you want to change the settings for \emph{all} following progressbar, you can use the command
\begin{lstlisting}
\progressbarchange{<options>}
\end{lstlisting}

So basically
\begin{lstlisting}
\progressbar{0.3}\\
\progressbar[roundnessr=0.5,ticksheight=1,tickswidth=1.5pt]{0.4}\\
\progressbar[roundnessr=0.5,ticksheight=1,tickswidth=1.5pt]{0.5}\\
\progressbar[roundnessr=0.5,ticksheight=1,tickswidth=1.5pt]{0.6}
\end{lstlisting}
gives you the same as
\begin{lstlisting}
\progressbar{0.3}\\
\progressbarchange{roundnessr=0.5,ticksheight=1,tickswidth=1.5pt}
\progressbar{0.4}\\
\progressbar{0.5}\\
\progressbar{0.6}
\end{lstlisting}

However, keep in mind that in the second case the options are changed globally. Therefore, all following progressbars will keep the changed design (as long as you don't call \lstinline+\progressbarchange{<options>}+ with other options again). (You can find an explanation of all options in the section \ref{options}.)

\section{Options}\label{options}
\subsection{Global and local options}
You can set global options when you load the \texttt{progressbar} with \lstinline+\usepackage[options]{progressbar}+ and with the command \lstinline+\progressbarchange{<options>}+. These options affect all following calls of the commands \lstinline+\progressbar{<number>}+ and \lstinline+\progressbar[<options>]{<number>}+.

However, you can override global options with local options specified with \lstinline+\progressbar[<options>]{<number>}+.

\subsection{Options, their defaults and how to change them}
All listed options can be used globally and locally.

You will notice that some of the options are available with the prefix \texttt{r} (standing for relative) aswell as with the prefix \texttt{a} (standing for absolute). I would recommend you to always use those options with the prefix \texttt{r}, as using absolute values might not interact too well with the rest of your documents settings. But as long as you know what you are doing, it's up to you.

\DescribeMacro{heightr} default=\texttt{1}\\
	The progressbars height as a fraction of the textheight\footnote{I used the capital letter ``I'' as a reference for the textheight}.
\begin{lstlisting}
\progressbar[heightr=1]{0.1}A progressbar that has the same height as the text\\
\progressbar[heightr=0.5]{0.9}A progressbar that has half the height
\end{lstlisting}
	\progressbar[heightr=1]{0.1} A progressbar that has the same height as the text\\
	\progressbar[heightr=0.5]{0.9} A progressbar that has half the height

\DescribeMacro{heighta} default=\texttt{unused}\\
	With this option you can define the progressbars height absolutely.
\begin{lstlisting}
\progressbar[heighta=2cm]{0.3} A progressbar that has the height 2~cm\\
\progressbar[heighta=10pt]{0.7} A progressbar that has the height 10~pt\\
\progressbar[heighta=\heightof{a} + 0.8pt]{0.42} A progressbar whose upper border starts at the same height as the letter "a"
\end{lstlisting}
	\progressbar[heighta=2cm]{0.3} A progressbar that has the height 2~cm\\
	\progressbar[heighta=10pt]{0.7} A progressbar that has the height 10~pt\\
	\progressbar[heighta=\heightof{a} + 0.8pt]{0.42} A progressbar whose upper border starts at the same height as the letter "a"\footnote{The \texttt{\textbackslash{}heightof} command and the possibility of adding is provided by the package \texttt{calc}}

\DescribeMacro{roundnessr} default=\texttt{0.15}\\
	\texttt{progressbar} allows rounded corners. With this option you can set them as a fraction of the progressbars height. You would not want to use numbers higher than $0.5$.
\begin{lstlisting}
\progressbar[roundnessr=0.25]{0.8} More rounder corners than the default\\
\progressbar[roundnessr=0.5]{0.5} In fact no more corners -- complete roundness
\end{lstlisting}
	\progressbar[roundnessr=0.25]{0.8} More rounder corners than the default\\
	\progressbar[roundnessr=0.5]{0.5} In fact no more corners -- complete roundness

\DescribeMacro{roundnessa} default=\texttt{unused}\\
	You can also define the corners radius as absolute values.
\begin{lstlisting}
\progressbar[roundnessa=2pt]{0} Rounded corners radius 2~pt\\
\progressbar[roundnessa=0cm]{1} No rounded corners
\end{lstlisting}
	\progressbar[roundnessa=2pt]{0} Rounded corners radius 2~pt\\
	\progressbar[roundnessa=0cm]{1} No rounded corners

\DescribeMacro{width} default=\texttt{6em}\\
	The width of the progressbar.
\begin{lstlisting}
\progressbar[width=5cm]{0.123} Width: 5~cm\\
\progressbar[width=20em]{0.785} Width: 20~em
\end{lstlisting}
	\progressbar[width=5cm]{0.123} Width: 5~cm\\
	\progressbar[width=20em]{0.785} Width: 20~em

\DescribeMacro{borderwidth} default=\texttt{0.8pt}\\
	The linewidth of the progressbars border.
\begin{lstlisting}
\progressbar[borderwidth=2pt]{0.6} Borderwidth: 2~pt\\
\progressbar[borderwidth=0.025em]{0.3} Borderwidth: 0.025~em
\end{lstlisting}
	\progressbar[borderwidth=2pt]{0.6} Borderwidth: 2~pt\\
	\progressbar[borderwidth=0.025em]{0.3} Borderwidth: 0.025~em

\DescribeMacro{subdivisions} default=\texttt{10}\\
	As you may have noticed, (by default) the progressbar also has ticks. Those ticks splits the progressbar in multiple subdivisions. You can define the number of subdivisions with \texttt{subdivisions=<number>}. Therefore the number of ticks is $\texttt{<number>}-1$.
\begin{lstlisting}
\progressbar[subdivisions=3]{0.666667} 3 subdivisions and 2 ticks\\
\progressbar[subdivisions=15]{0.466667} 15 subdivisions and 14 ticks
\end{lstlisting}
	\progressbar[subdivisions=3]{0.666667} 3 subdivisions and 2 ticks\\
	\progressbar[subdivisions=15]{0.466667} 15 subdivisions and 14 ticks

\DescribeMacro{tickswidth} default=\texttt{0.4pt}\\
	The linewidth of the ticks.
\begin{lstlisting}
\progressbar[tickswidth=1mm]{0.55} Tickswidth: 1~mm\\
\progressbar[tickswidth=0.1pt]{0.4} Tickswidth: 0.1~pt
\end{lstlisting}
	\progressbar[tickswidth=1mm]{0.55} Tickswidth: 1~mm\\
	\progressbar[tickswidth=0.1pt]{0.4} Tickswidth: 0.1~pt

\DescribeMacro{ticksheight} default=\texttt{0.33}\\
	The height of the ticks as a fraction of the total progressbars height.
\begin{lstlisting}
\progressbar[ticksheight=0.1]{0.22} Ticksheight: 10 ~\% of the total height\\
\progressbar[ticksheight=1]{0.88} Ticks are end-to-end
\end{lstlisting}
	\progressbar[ticksheight=0.1]{0.22} Ticksheight: 10 ~\% of the total height\\
	\progressbar[ticksheight=1]{0.88} Ticks are end-to-end

\DescribeMacro{linecolor} default=\texttt{black}

\DescribeMacro{tickscolor} default=\texttt{black}

\DescribeMacro{emptycolor} default=\texttt{black!10}

\DescribeMacro{filledcolor} default=\texttt{black!60}\\
These options should be self-explaining. Just use \texttt{xcolor}-color-definitions (use color names or the syntax \lstinline+<color-name>!<number between 0 and 100>+) for brighter colors).
\begin{lstlisting}
\progressbar[linecolor=blue,tickscolor=orange,emptycolor=yellow,filledcolor=red]{0.6}
\end{lstlisting}
	\progressbar[linecolor=blue,tickscolor=orange,emptycolor=yellow,filledcolor=red]{0.6}
