The \Lcs{psdots}, \Lcs{psline}, \Lcs{pspolygon}, \Lcs{pscurve}, \Lcs{psecurve} and \Lcs{psccurve} graphics objects let you plot data in a variety of ways. However, first you have to generate the data and enter it as coordinate pairs \CAny. The plotting macros in this section give you other ways to get and use the data. %(Section \ref{S-axes} tells you how to generate axes.) To parameter \Lkeyset{plotstyle=style} determines what kind of plot you get. Valid styles are \Lkeyval{dots}, \Lkeyval{line}, \Lkeyval{polygon}, \Lkeyval{curve}, \Lkeyval{ecurve}, \Lkeyval{ccurve}. E\,,g., if the \Lkeyword{plotstyle} is \Lkeyval{polygon}, then the macro becomes a variant of the \Lcs{pspolygon} object. You can use arrows with the plot styles that are open curves, but there is no optional argument for specifying the arrows. You have to use the \Lkeyword{arrows} parameter instead. No\XInfoDanger{~} PostScript error checking is provided for the data arguments. %Read Appendix %\ref{S-raw} before including PostScript code in the arguments. There are system-dependent limits on the amount of data \TeX{} and PostScript can handle. You are much less likely to exceed the PostScript limits when you use the \Lkeyval{line}, \Lkeyval{polygon} or \Lkeyval{dots} plot style, with \LKeyword{showpoints=false}, \LKeyset{linearc=0pt}, and no arrows. Note that the lists of data generated or used by the plot commands cannot contain units. The values of \Lcs{psxunit} and \Lcs{psyunit} are used as the unit. \section{Plotting data records} \begin{BDef} \Lcs{fileplot}\OptArgs\Largb{file}\\ \Lcs{psfileplot}\OptArgs\Largb{file}\\ \Lcs{dataplot}\OptArgs\Largb{\Lcs{\Larga{macro}}}\\ \Lcs{psdataplot}\OptArgs\Largb{\Lcs{\Larga{macro}}}\\ \Lcs{savedata}\Largb{\Lcs{\Larga{macro}}}\Largs{data}\\ \Lcs{readdata}\Largb{\Lcs{\Larga{macro}}}\Largb{file}\\ \Lcs{psreadColumnData}\Largb{colNo}\Largb{delimiter}\Largb{\Lcs{\Larga{macro}}}\Largb{filename}\\ \Lcs{listplot}\Largb{data}\\ \Lcs{pslistplot}\Largb{data} \end{BDef} The macros with a preceeding \verb|ps| are equivalent to those without. \Lcs{fileplot} is the simplest of the plotting functions to use. You just need a file that contains a list of coordinates (without units), such as generated by Mathematica or other mathematical packages. The data can be delimited by curly braces \verb|{ }|, parentheses \verb|( )|, commas, and/or white space. Bracketing all the data with square brackets \verb|[ ]| will significantly speed up the rate at which the data is read, but there are system-dependent limits on how much data \TeX{} can read like this in one chunk. (The \verb|[| \emph{must} go at the beginning of a line.) The file should not contain anything else (not even \Lcs{endinput}), except for comments marked with \verb|%|. \Lcs{fileplot} only recognizes the \Lkeyval{line}, \Lkeyval{polygon} and \Lkeyval{dots} plot styles, and it ignores the \Lkeyword{arrows}, \Lkeyword{linearc} and \Lkeyword{showpoints} parameters. The \Lcs{listplot} command, described below, can also plot data from file, without these restrictions and with faster \TeX{} processing. However, you are less likely to exceed PostScript's memory or operand stack limits with \Lcs{fileplot}. If you find that it takes \TeX{} a long time to process your \Lcs{fileplot} command, you may want to use the \Lcs{PSTtoEPS} command described on page \pageref{+PSTtoEPS}. This will also reduce \TeX's memory requirements. \Lcs{dataplot} is also for plotting lists of data generated by other programs, but you first have to retrieve the data with one of the following commands: \Larg{data} or the data in \Larg{file} should conform to the rules described above for the data in \Lcs{fileplot} (with \Lcs{savedata}, the data must be delimited by \verb|[ ]|, and with \Lcs{readdata}, bracketing the data with \verb|[ ]| speeds things up). You can concatenate and reuse lists, as in \begin{lstlisting}[style=syntax] \readdata{\foo}{data/foo.data} \readdata{\bar}{data/bar.data} \dataplot{\foo\bar} \dataplot[origin={0,1}]{\bar} \end{lstlisting} The \Lcs{readdata} and \Lcs{dataplot} combination is faster than \Lcs{fileplot} if you reuse the data. \Lcs{fileplot} uses less of \TeX's memory than \Lcs{readdata} and \Lcs{dataplot} if you are also use \Lcs{PSTtoEPS}. Here is a plot of $\int\sin(x)\mathrm{d}x$. The data was generated by Mathematica, with \begin{lstlisting} Table[{x,N[SinIntegral[x]]},{x,0,20}] \end{lstlisting} and then copied to this document. \begin{LTXexample}[pos=t] \pspicture(4,3) \psset{xunit=.2cm,yunit=1.5cm} \savedata{\mydata}[ {{0, 0}, {1., 0.946083}, {2., 1.60541}, {3., 1.84865}, {4., 1.7582}, {5., 1.54993}, {6., 1.42469}, {7., 1.4546}, {8., 1.57419}, {9., 1.66504}, {10., 1.65835}, {11., 1.57831}, {12., 1.50497}, {13., 1.49936}, {14., 1.55621}, {15., 1.61819}, {16., 1.6313}, {17., 1.59014}, {18., 1.53661}, {19., 1.51863}, {20., 1.54824}}] \dataplot[plotstyle=curve,showpoints,dotstyle=triangle]{\mydata} \psline{<->}(0,2)(0,0)(22,0) \endpspicture \end{LTXexample} \Lcs{listplot} is yet another way of plotting lists of data. This time, should be a list of data (coordinate pairs), delimited only by white space. \Larg{list} is first expanded by \TeX{} and then by PostScript. This means that \Larg{list} might be a PostScript program that leaves on the stack a list of data, but you can also include data that has been retrieved with \Lcs{readdata} and \Lcs{dataplot}. However, when using the \Lkeyval{line}, \Lkeyval{polygon} or \Lkeyval{dots} plotstyles with \LKeyset{showpoints=false}, \LKeyset{linearc=0pt} and no arrows, \Lcs{dataplot} is much less likely than \Lcs{listplot} to exceed PostScript's memory or stack limits. In the preceding example, these restrictions were not satisfied, and so the example is equivalent to when \Lcs{listplot} is used: \begin{lstlisting}[style=syntax] ... \listplot[plotstyle=curve,showpoints=true,dotstyle=triangle]{\mydata} ... \end{lstlisting} \section{Plotting mathematical functions} \begin{BDef} \Lcs{psplot}\OptArgs\Largb{$x_!\min@$}\Largb{$x_!\max@$}\Largb{function}\\ \Lcs{parametricplot}\OptArgs\Largb{$t_!\min@$}\Largb{$t_!\max@$}\Largb{x(t) y(t)} \end{BDef} \Lcs{psplot} can be used to plot a function $f(x)$, if you know a little PostScript. \Larg{function} should be the PostScript or algebraic code for calculating $f(x)$. Note that you must use $x$ as the dependent variable. \begin{lstlisting} \psplot[plotpoints=200]{0}{720}{x sin} \end{lstlisting} plots $\sin(x)$ from 0 to 720 degrees, by calculating $\sin(x)$ roughly every 3.6 degrees and then connecting the points with \Lcs{psline}. Here are plots of $\sin(x)\cos((x/2)^2)$ and $\sin^2(x)$: \begin{LTXexample}[pos=t] \pspicture(0,-1)(4,1) \psset{xunit=1.2pt} \psplot[linecolor=gray,linewidth=1.5pt,plotstyle=curve]{0}{90}{x sin dup mul} \psplot[plotpoints=100]{0}{90}{x sin x 2 div 2 exp cos mul} \psline{<->}(0,-1)(0,1) \psline{->}(100,0) \endpspicture \end{LTXexample} \Lcs{parametricplot} is for a parametric plot of $(x(t),y(t))$. \Larg{function} is the PostScript code or algebraic expression for calculating the pair $x(t)$ $y(t)$. For example, \begin{LTXexample}[wide,width=4cm] \pspicture(3,3) \parametricplot[plotstyle=dots,plotpoints=13]% {-6}{6}{1.2 t exp 1.2 t neg exp} \endpspicture \end{LTXexample} plots 13 points from the hyperbola $xy=1$, starting with $(1.2^{-6},1.2^6)$ and ending with $(1.2^6,1.2^{-6})$. Here is a parametric plot of $(\sin(t),\sin(2t))$: \begin{LTXexample}[wide,width=4cm] \pspicture(-2,-1)(2,1) \psset{xunit=1.7cm} \parametricplot[linewidth=1.2pt,plotstyle=ccurve]% {0}{360}{t sin t 2 mul sin} \psline{<->}(0,-1.2)(0,1.2) \psline{<->}(-1.2,0)(1.2,0) \endpspicture \end{LTXexample} The number of points that the \Lcs{psplot} and \Lcs{parametricplot} commands calculate is set by the \LKeyset{plotpoints=} parameter. Using "curve" or its variants instead of "line" and increasing the value of \Lkeyword{plotpoints} are two ways to get a smoother curve. Both ways increase the imaging time. Which is better depends on the complexity of the computation. (Note that all PostScript lines are ultimately rendered as a series (perhaps short) line segments.) Mathematica generally uses "lineto" to connect the points in its plots. The default minimum number of plot points for Mathematica is 25, but unlike \Lcs{psplot} and \Lcs{parametricplot}, Mathematica increases the sampling frequency on sections of the curve with greater fluctuation. \part{New commands} %-------------------------------------------------------------------------------------- \section[Extended syntax]{Extended syntax for \nxLcs{psplot}, \nxLcs{psparametricplot}, and \nxLcs{psaxes}} There is now a new optional argument for \Lcs{psplot} and \Lcs{psparametricplot} to pass additional \PS commands into the code. This makes the use of \Lcs{pstVerb} in most cases superfluous. \begin{BDef} \Lcs{psplot}\OptArgs\Largb{x0}\Largb{x1}\OptArg{PS commands}\Largb{function}\\ \Lcs{psparametricplot}\OptArgs\Largb{t0}\Largb{t1}\OptArg{PS commands}\Largb{x(t) y(t)}\\ \Lcs{psaxes}\OptArgs\OptArg*{\Largb{arrows}}\coord0\coord1\coord2\OptArg{Xlabel,Xangle}\OptArg{Ylabel,Yangle} \end{BDef} The macro \Lcs{psaxes} has now four optional arguments, one for the setting, one for the arrows, one for the x-label and one for the y-label. If you want only a y-label, then leave the x one empty. A missing y-label is possible. The following examples show how it can be used. \begin{lstlisting} \begin{pspicture}(-1,-0.5)(12,5) \psaxes[Dx=100,dx=1,Dy=0.00075,dy=1]{->}(0,0)(12,5)?\ON?[$x$,-90][$y$,180]?\OFF? \psplot[linecolor=red, plotstyle=curve,linewidth=2pt,plotpoints=200]{0}{11}% ?\ON?[ /const1 3.3 10 8 neg exp mul def ?\OFF? ?\ON?/s 10 def ?\OFF? ?\ON?/const2 6.04 10 6 neg exp mul def ] % optional PS commands?\OFF? { const1 x 100 mul dup mul mul Euler const2 neg x 100 mul dup mul mul exp mul 2000 mul} \end{pspicture} \end{lstlisting} \begin{pspicture}(-1,-0.5)(12,5) \psaxes[Dx=100,dx=1,Dy=0.00075,dy=1]{->}(0,0)(12,5)[$x$,-90][$y$,180] \psplot[linecolor=red, plotstyle=curve,linewidth=2pt,plotpoints=200]{0}{11}% [ /const1 3.3 10 8 neg exp mul def /s 10 def /const2 6.04 10 6 neg exp mul def ] % optional PS commands { const1 x 100 mul dup mul mul Euler const2 neg x 100 mul dup mul mul exp mul 2000 mul} \end{pspicture} %-------------------------------------------------------------------------------------- \clearpage \section{New Macro \nxLcs{psBoxplot}} %-------------------------------------------------------------------------------------- A \Index{box-and-whisker plot} (often called simply a \Index{box plot}) is a histogram-like method of displaying data, invented by John.\,Tukey. The box-and-whisker plot is a box with ends at the quartiles $Q_1$ and $Q_3$ and has a statistical median M as a horizontal line in the box. The "`whiskers"* are lines to the farthest points that are not outliers (i.e., that are within 3/2 times the interquartile range of $Q_1$ and $Q_3$). Then, for every point more than 3/2 times the interquartile range from the end of a box, is a dot. The only special optional arguments, beside all other which are valid for drawing lines and filling areas, are \Lkeyword{IQLfactor}, \Lkeyword{barwidth}, and \Lkeyword{arrowlength}, where the latter is a factor which is multiplied with the barwidth for the line ends. The \Lkeyword{IQLfactor}, preset to 1.5, defines the area for the outliners. The outliners are plotted as a dot and take the settings for such a dot into account, eg. \Lkeyword{dotstyle}, \Lkeyword{dotsize}, \Lkeyword{dotscale}, and \Lkeyword{fillcolor}. The default is the black dot. %\begin{LTXexample}[pos=t,preset=\centering] \begin{pspicture}(-1,-1)(12,14) \psset{yunit=0.1,fillstyle=solid} \savedata{\data}[100 90 120 115 120 110 100 110 100 90 100 100 120 120 120] \rput(1,0){\psBoxplot[fillcolor=red!30]{\data}} \rput(1,105){2001} \savedata{\data}[90 120 115 116 115 110 90 130 120 120 120 85 100 130 130] \rput(3,0){\psBoxplot[arrowlength=0.5,fillcolor=blue!30]{\data}} \rput(3,107){2008} \savedata{\data}[35 70 90 60 100 60 60 80 80 60 50 55 90 70 70] \rput(5,0){\psBoxplot[barwidth=40pt,arrowlength=1.2,fillcolor=red!30]{\data}} \rput(5,65){2001} \savedata{\data}[60 65 60 75 75 60 50 90 95 60 65 45 45 60 90] \rput(7,0){\psBoxplot[barwidth=40pt,fillcolor=blue!30]{\data}} \rput(7,65){2008} \savedata{\data}[20 20 25 20 15 20 20 25 30 20 20 20 30 30 30] \rput(9,0){\psBoxplot[fillcolor=red!30]{\data}} \rput(9,22){2001} \savedata{\data}[20 30 20 35 35 20 20 60 50 20 35 15 30 20 40] \rput(11,0){\psBoxplot[fillcolor=blue!30,linestyle=dashed]{\data}} \rput(11,25){2008} \psaxes[dy=1cm,Dy=10](0,0)(12,130) \end{pspicture} %\end{LTXexample} \begin{lstlisting} \begin{pspicture}(-1,-1)(12,14) \psset{yunit=0.1,fillstyle=solid} \savedata{\data}[100 90 120 115 120 110 100 110 100 90 100 100 120 120 120] \rput(1,0){?\ON?\psBoxplot?\OFF?[fillcolor=red!30]{\data}} \rput(1,105){2001} \savedata{\data}[90 120 115 116 115 110 90 130 120 120 120 85 100 130 130] \rput(3,0){?\ON?\psBoxplot?\OFF?[arrowlength=0.5,fillcolor=blue!30]{\data}} \rput(3,107){2008} \savedata{\data}[35 70 90 60 100 60 60 80 80 60 50 55 90 70 70] \rput(5,0){?\ON?\psBoxplot?\OFF?[barwidth=40pt,arrowlength=1.2,fillcolor=red!30]{\data}} \rput(5,65){2001} \savedata{\data}[60 65 60 75 75 60 50 90 95 60 65 45 45 60 90] \rput(7,0){?\ON?\psBoxplot?\OFF?[barwidth=40pt,fillcolor=blue!30]{\data}} \rput(7,65){2008} \savedata{\data}[20 20 25 20 15 20 20 25 30 20 20 20 30 30 30] \rput(9,0){?\ON?\psBoxplot?\OFF?[fillcolor=red!30]{\data}} \rput(9,22){2001} \savedata{\data}[20 30 20 35 35 20 20 60 50 20 35 15 30 20 40] \rput(11,0){?\ON?\psBoxplot?\OFF?[fillcolor=blue!30,linestyle=dashed]{\data}} \rput(11,25){2008} \psaxes[dy=1cm,Dy=10](0,0)(12,130) \end{pspicture} \end{lstlisting} The next example uses an external file for the data, which must first be read by the macro \Lcs{readdata}.

As seen for the blue line for $x=0$ we get $y(0)=(0+3)\cdot 0.5=1.5$. Changes with \Lcs{pstScalePoints} are always global to all following \Lcs{listplot} macros.

When using the \Lkeyword{comma} or \Lkeyword{trigLabels} option, the macros \Lcs{pshlabel} and \Lcs{psvlabel} shouldn't be redefined, because the package does it itself internally in these cases.

It is \emph{always} the last pair in a sequence of allowed coordinates for the \Lcs{psaxes} macro. The other ones are ignored; they are not valid for the polar coordinate system. However, if the angle is set to 0 it is changed to 360 degrees for a full circle. \begin{LTXexample}[pos=r] \begin{pspicture}(-1,-1)(5.75,5.75) \psaxes[axesstyle=polar, subticks=2](5,90) \psline[linewidth=2pt]{->}(5;15) \psline[linewidth=2pt]{->}(2;40) \psline{->}(2;10)(4;85) \end{pspicture} \end{LTXexample} All valid optional arguments for the axes are also possible for the polar style, if they make sense \ldots\ :-) Important are the \Lkeyword{Dy} option, it defines the angle interval and \Lkeyword{subticks}, for the intermediate circles and lines. The number can be different for the circles (\Lkeyword{ysubticks}) and the lines (\Lkeyword{xsubticks}). \begin{LTXexample}[pos=r] \begin{pspicture}(-3,-1)(4.5,4.5) \psaxes[axesstyle=polar, subticklinestyle=dashed, subticks=2,Dy=20](4,140) \psline[linewidth=2pt]{->}(4;15) \psline[linewidth=2pt]{->}(2;40) \psline{->}(2;10)(3;85) \end{pspicture} \end{LTXexample} \begin{lstlisting} \begin{pspicture}(-3.5,-3.5)(3.5,3.5) \psaxes[axesstyle=polar](3,0) \psplot[polarplot,algebraic,linecolor=blue,linewidth=2pt, plotpoints=2000]{0}{TwoPi 4 mul}{2*(sin(x)-x)/(cos(x)+x)} \end{pspicture} % \begin{pspicture}(-3.5,-3.5)(3.5,3.5) \psaxes[axesstyle=polar,subticklinestyle=dashed,subticks=2, xlabelFontSize=\scriptstyle](3,360) \psplot[polarplot,algebraic,linecolor=red,linewidth=2pt, plotpoints=2000]{0}{TwoPi}{6*sin(x)*cos(x)} \end{pspicture} \end{lstlisting} %\begin{LTXexample}[pos=b] \begin{pspicture}(-3.5,-3.5)(3.5,3.5) \psaxes[axesstyle=polar](3,0) \psplot[polarplot,algebraic,linecolor=blue,linewidth=2pt, plotpoints=2000]{0}{TwoPi 4 mul}{2*(sin(x)-x)/(cos(x)+x)} \end{pspicture} % \begin{pspicture}(-3.5,-3.5)(3.5,3.5) \psaxes[axesstyle=polar,subticklinestyle=dashed,subticks=2, ylabelFontSize=\scriptstyle](3,360) \psplot[polarplot,algebraic,linecolor=red,linewidth=2pt, plotpoints=2000]{0}{TwoPi}{6*sin(x)*cos(x)} \end{pspicture} %\end{LTXexample} %-------------------------------------------------------------------------------------- \subsection{Option \nxLkeyword{xyAxes}, \nxLkeyword{xAxis} and \nxLkeyword{yAxis}}\label{xyAxes} %-------------------------------------------------------------------------------------- Syntax: \begin{lstlisting}[style=syntax] xyAxes=true|false xAxis=true|false yAxis=true|false \end{lstlisting} Sometimes there is only a need for one axis with ticks. In this case you can set one of the preceding options to false. The \Lkeyword{xyAxes} only makes sense when you want to set both x and y to true with only one command, back to the default, because with \Lkeyword{xyAxes}=\false you get nothing with the \Lcs{psaxes} macro. \begin{LTXexample} \begin{pspicture}(5,1) \psaxes[yAxis=false,linecolor=blue]{->}(0,0.5)(5,0.5) \end{pspicture} \begin{pspicture}(1,5) \psaxes[xAxis=false,linecolor=red]{->}(0.5,0)(0.5,5) \end{pspicture} \begin{pspicture}(1,5) \psaxes[xAxis=false,linecolor=red, ylabelPos=right]{->}(0.5,0)(0.5,5) \end{pspicture}\\[0.5cm] \begin{pspicture}(5,1) \psaxes[yAxis=false,linecolor=blue, xlabelPos=top]{->}(0,0.5)(5,0.5) \end{pspicture} \end{LTXexample} As seen in the example, a single y axis gets the labels on the left side.

%------------------------------------------------------------------------------------ By default the macro \Lcs{readdata} reads every data record, which could be annoying when you have some text lines at top of your data files or when there are more than 10000 records to read. \LPack{pst-plot} defines two additional keys \Lkeyword{ignoreLines} and \Lkeyword{nStep}, which allows you to ignore preceeding lines, e.\,g. \Lkeyword{ignoreLines}=2, or to read only a selected part of the data records, e.\,g. \Lkeyword{nStep}=10, only every 10\textsuperscript{th} record is saved. \begin{lstlisting} \readdata[ignoreLines=2]{\dataA}{data/stressrawdata.data} \readdata[nStep=10]{\dataA}{data/stressrawdata.data} \end{lstlisting} The default value for \Lkeyword{ignoreLines} is $0$ and for \Lkeyword{nStep} is $1$. the following data file has two text lines which shall be ignored by the \Lcs{readdata} macro: \begin{LTXexample}[width=4cm]

options for \nxLcs{listplot}} %-------------------------------------------------------------------------------------- By default the plot macros \Lcs{dataplot}, \Lcs{fileplot} and \Lcs{listplot} plot every data record. There are noew additional keys \Lkeyword{nStep}, \Lkeyword{nStart}, \Lkeyword{nEnd}, and \Lkeyword{xStep}, \Lkeyword{xStart}, \Lkeyword{xEnd}, which allows to plot only a selected part of the data records, e.\,g. \Lkeyword{nStep}=10. These "`n"' options mark the number of the record to be plotted ($0,1,2,...$) and the "`x"' ones the x-values of the data records. The new options are only available for the \Lcs{listplot} macro, which is not a real limitation, because all data records can be read from a file with the \Lcs{readdata} macro (see example files or~\cite{dtk02.2:jackson.voss:plot-funktionen}): \begin{lstlisting}[style=syntax] \readdata[nStep=10]{\data}{data/data1.data} \end{lstlisting} \xLcs{readdata} The use \Lkeyword{nStep} and \Lkeyword{xStep} options only make real sense when also using the option \Lkeyset{plotstyle=dots}. Otherwise the coordinates are connected by a line as usual. Also the \Lkeyword{xStep} option needs increasing x values. Note that \Lkeyword{nStep} can be used for \Lcs{readdata} and for \Lcs{listplot}. If used in both macros then the effect is multiplied, e.g. \Lcs{readdata} with \Lkeyword{nStep}=5 and \Lcs{listplot} with \Lkeyword{nStep}=10 means, that only every 50\textsuperscript{th} data record is read and plotted. When both, \verb|x/yStart/End| are defined then the values are also compared with both values. %-------------------------------------------------------------------------------------- \subsection{Options \nxLkeyword{nStep}, \nxLkeyword{xStep}, and \nxLkeyword{yStep}}\label{nxstep} %-------------------------------------------------------------------------------------- The datafile \verb|data.data| contains $1000$ data records.
