-\begin{abstract}
- Plotting of external data records is one of the standard problems of
- technical and industrial publications. One common approach is
- importing the data files into an external program, such as
- \verbI{gnuplot}, provided with axes of coordinates and further
- references, and finally exported to \LaTeX. By contrast, in this
- article we explain ways to get proper data plotting without using
- external applications.
-\end{abstract}
-
-\section{Introduction}
-
-The history and the meaning of \PS{} have been covered sufficiently in
-many articles. For the programming language \PS{} have a look at
-\cite{PostScript,ThinkPostScript}. The package \verbI{pst-plot}
-\cite{pst-plot} under consideration here is part of the \verbI{pstricks}
-project. It must be loaded into a \LaTeX{} document as usual with
-\CMD{usepackage\{pst-plot\}} or alternatively, for documents written in Plain\TeX,
-with \CMD{input pst-plot.tex}.
-
-\verbI{pst-plot} provides three plot macros for the representation of
-external data, with the following syntax:
-
-{\small\begin{verbatim}
-\listplot*[<parameter>]{<data macro>}
-\dataplot*[<parameter>]{<data macro>}
-\fileplot*[<parameter>]{<file name>}
-\end{verbatim}}
-
- The starred forms have the same meaning as with all macros of
- \verbI{pstricks}: to plot the data in a reversed mode. Thus, for a
- default black-on-white diagram one produces the negative with the
- starred command form, namely white-on-black. Additionally, a negative plot
- implies that \PS{} closes the path of the points from the last to
- the first one and fills all points inside this closed path with the
- actual fillcolor. For our purposes in this article there will be no
- real sense in this negative view; therefore, all of the following
- examples are plotted with the normal (unstarred) form only.
-
-For further information about the package \verbI{pstricks} have a look at the (more
-or less) official documentation \cite{pstricks}, or the extensive
-description in the ``standard \LaTeX'' book \cite{companion} or in
-\cite{girou:01:,girou:02:}. Altogether, however, these do not fully
-describe the substantial differences between these three plot macros.
-
-For all of the examples in this article, the complete \verbI{pspicture}
-environment is indicated, so that the examples may be directly copied.
-The Documentation of the \verbI{multido} macro used here can be found in the
-package itself \cite{multido}; macros not otherwise mentioned are
-described in the \verbI{pstricks} documentation \cite{pstricks}.
-
-The general \verbI{plotstyle} parameter is particularly important, and
-can take the values shown in table \ref{tab:options}.
-
-\begin{table}
-\caption{Possible options}\label{tab:options}
-\begin{tabularx}{1.0\linewidth}{r|X}
-style option& meaning\\
-\hline
-\verbI{plotstyle=dots} & plot $(x,y)$ as a dot\\
-\verbI{=line} & draw a line from a dot to the following one\\
-\verbI{=polygon} & nearly the same as \verbI{line}, but with a line from the last to the first dot\\
-\verbI{=curve} & interpolation between three dots, whereby the curve can go beyond the point of origin and/or termination point\\
-\verbI{=ecurve} & like \verbI{curve}, but ends at the first/last dot\\
-\verbI{=ccurve} & like \verbI{curve}, but closed\\
-\end{tabularx}
-\end{table}
-
-By default, the \verbI{line} option is selected.
-
-The following general commands are also useful in conjunction with the
-plot commands. They are also defined by the \verbI{pst-plot} package:
-
-{\small\begin{verbatim}
-\readdata{<data macro name>}{<file name>}
-\savedata{<data macro name>}{<file name>}
-\end{verbatim}}
-
- In the following examples only the \CMD{readdata} macro is used,
- but it would be straightforward to create examples with
- \CMD{savedata}.
-
-\section{Examples for \CMD{listplot}}
-
-The syntax of \CMD{listplot} is :
-
-{\small\begin{verbatim}
-\listplot{<data macro name>}
-\end{verbatim}}
-
- The data macro may contain any additional \AllTeX- or
- \PS-commands. The \AllTeX{} macros are expanded first before they
- are passed as a \textbf{list} of $x|y$ values to \PS. The data
- records can be defined inside the document like
-
-{\small\begin{verbatim}
-\newcommand{\dataA}{
- 1.00000000 1.00000000
- 0.56000000 0.31000000
- 0.85841600 0.17360000
- ...
-\end{verbatim}}
-
-\noindent or can be read from an external data file with the \CMD{readdata} macro:
-
-{\small\begin{verbatim} \readdata{\dataA}{/anyPath/data.dat}
-\end{verbatim}}
-
- The example in figure \ref{fig:listplot1} shows the Henon
- attractor, a typical graphic of a system with chaotic
- behavior\cite{voss:chaos}.
-
- Figure \ref{fig:listplot2} is nearly the same as
- figure~\ref{fig:listplot1}, with the addition of \PS{} code to
- get
- the "Draft" watermark. (Some familiarity with \PS{} is needed to
- fully understand its operation.) To save space, listing
- \ref{lst:listplot2} does not contain the data, which is nothing
- more than a sequence of pairs of floats, each value separated by a
- space, as shown above.

-Naturally, \verbI{[... data ...]} is replaced by all
-the $x|y$-values; they're omitted here only to save space.
-
-As an alternative to direct modification of the data set passed to
-\CMD{listplot}, one can redefine the macro \verbI{defScalePoints} from
-\verbI{pst-plot}. For example, to change the $x|y$ values and then
-rotate the whole plotted graphic (don't ask why!), the redefinition is
-as shown in listing \ref{lst:listplot3}.

-
-Thus, the advantage of \CMD{listplot} is that one can easily modify the
-data values without any external program. Here is one more example---suppose
-you have the following data records:
-
-{\small\begin{verbatim}
-1050, 0.368
-1100, 0.371
-1200, 0.471
-1250, 0.428
-1300, 0.391
-1350, 0.456
-1400, 0.499
-1500, 1.712
-1550, 0.475
-1600, 0.497
-\end{verbatim}}
-
-\noindent which perhaps came automatically from a technical device. The
-unit of the x-values is micrometer but it makes more sense to use
-millimeter for the plot. A redefinition of \verbI{ScalePoints} makes it
-very easy to plot the data with this change of scale:
-
-\begin{lstlisting}[caption={Rescale all x values},label={lst:lstplot}]
- \makeatletter
-\pst@def{ScalePoints}<%
- /y ED /x ED

-\section{Examples for \CMD{dataplot}}
-
-\CMD{dataplot} has the same syntax as \CMD{listplot}, so the first
-question is, what is the difference between the two? \CMD{listplot}
-builds a list of all the data and then multiplies all values with the
-length unit. This takes some time, so you may prefer a so-called
-``quick plot'', where the data can be passed more quickly to \PS,
-depending on the plotstyle and especially the option \verbI{showpoints}.
-Table \ref{tab:quickplot} shows whether this is possible. A quick plot
-is not possible with \CMD{listplot}, whereas \CMD{dataplot} uses it
-whenever possible. When it is not possible, \CMD{dataplot} simply calls
-\CMD{listplot}.
-
-
-\def\hI{\hangindent=3em}
-\begin{table}[htb]
-\caption{Possible options for a ''quick plot``}\label{tab:quickplot}
-\begin{tabularx}{\columnwidth}{lX|l}
-plotstyle & options & macro\\\hline
-\verbI{line} & all, except & quick plot\\
- & \verbI{linearc}, \verbI{showpoints}, \verbI{arrows}, & \CMD{listplot}\\
-\verbI{polygon} & all, except & quick plot\\
- & \verbI{linearc}, \verbI{showpoints} & \CMD{listplot}\\
-\verbI{dots} & all & quick plot\\
-\verbI{bezier} & all, except & quick plot\\
- &\verbI{arrows}, \verbI{showpoints} & \CMD{listplot}\\
-\hI\verbI{cbezier} & all, except& \CMD{listplot}\\
- &\verbI{showpoints} & quick plot\\
-\verbI{curve} & all & \CMD{listplot}\\
-\verbI{ecurve} & all & \CMD{listplot}\\
-\verbI{ccurve} & all & \CMD{listplot}
-\end{tabularx}
-\end{table}
-
-
-\CMD{dataplot} needs to be passed a macro holding the data. The data is
-typically saved in an external file, which can be read by (for instance)
-the \CMD{readdata} macro, as follows:
-
-{\small\begin{verbatim}
-\readdata{<object name>}{<data file>}
-\end{verbatim}}
-
-\noindent For example:
-
-{\small\begin{verbatim}
-\readdata{\feigenbaum}{feigenbaum.data}
-\end{verbatim}}
-
-The amount of data is limited only by \TeX's memory. The above example
-can be plotted with:
-
-{\small\begin{verbatim}
-\dataplot{\feigenbaum}
-\end{verbatim}}
-
- Overlays with different data files are also possible. For example,
- figure~\ref{fig:dataplot} shows the use of two different data files
- which are plotted using one coordinate system. It shows the sorting
- time for ``Bubble-Sort'' and ``Select-Sort{}'' as a function of the
- number of the elements.
-

- \rput[r](9990,-20){elements}
- \rput[l](4500,800){Bubble-Sort}
- \rput[l](7500,200){Select-Sort}
-\end{pspicture}
-\end{lstlisting}
-
-In summary, the advantage of \CMD{dataplot} is the possibility of a
-''quick plot``, and the advantage of \CMD{listplot} is that it is easy
-to manipulate the data values before they are plotted.
-
-
-\section{Examples for \CMD{fileplot}}
-
-\CMD{fileplot} can be used whenever $(x|y)$ data that is saved in a file
-is to be plotted. The values must be given as pure numerical values in
-pairs, one pair on each line, and may have spaces, commas, parentheses,
-and braces as punctuation, as follows:
-
-\begin{verbatim}
-x y
-x,y
-(x,y)
-{x,y}
-\end{verbatim}
-
-The tab character (\CMD{t} or \acro{ASCII} \CMD{009}) is often used as a
-separator, but tab is \emph{not} valid here. Tabs may be converted to
-spaces in many ways, for example with the standard Unix utility
-\texttt{tr}:
-
-{\small\begin{verbatim}
-tr '\t' ' ' <inFile >outFile
-\end{verbatim}}
-
-The data files may also contain \% characters, but no other characters
-are allowed.
-
-Our first example for \CMD{fileplot} is shown in
-figure~\ref{fig:fileplot1}, which is an \acro{UV/VIS} absorber spectrum
-$A=\lg \frac{I_{0}}{I}$ as a function of the wavelength. The second
-example (figure~\ref{fig:fileplot2}) shows the evolution of a population
-as a function of the spawn factor (Feigenbaum diagram
-\cite{voss:chaos}). The source code for these images is shown in
-listings~\ref{lst:fileplot1} and~\ref{lst:fileplot2}.

-As you may see in listing \ref{lst:fileplot}, \CMD{fileplot} does little
-of its own. It first calls \CMD{readdata} to read the data, and then,
-depending on the kind of data and specified options, \CMD{fileplot} uses
-\CMD{dataplot} for a quick plot if possible. Otherwise, it falls back
-to \CMD{listplot}.

-\CMD{fileplot} has the advantage of being easy to use, but the
-disadvantage of needing a lot of memory: \TeX{} has to read the all the
-data values before it can process anything. As a rule of thumb, when
-there are more than 1000 data entries \TeX{}'s main menory must be
-increased. Furthermore, the running time may be enormous, especially on
-slow machines.
-
-To prevent such problems, one can use the \CMD{PSTtoEPS} macro to create
-an \texttt{eps} file. For more information, see the documentation of
-\verbI{pstricks} \cite{pstricks}.
