The graphing +screen can be interactive or non-interactive. + +For the interactive graphing screen, the user can enter an +expression representing a function of a single variable $x$, a polar +function of $t$, or a set of parametric equations that are functions +of $t$. Various controls are provided to change the viewing window, +for shifting horizontally and vertically, and for zooming in or out. + +For the non-interactive graphing screen, the screen is populated +when the user clicks a link created by \cs{sgraphLink}. +\cs{sgraphLink} passes such information as the function, +domain, and range to the graphing routines of {\AcroFLeX}. + +In this version of {\AcroFLeX}, up to four functions can be graphed +and four sets of plotted points can be displayed, on one graphing +screen. + +The graph screen itself is actually a SWF file, named +\texttt{acroflex.swf}. This SWF file is part of the {\AcroFLeX} +distribution. This package uses the \pkg{rmannot} package, also +written by this author, to create rich media annotations, to embed +\texttt{acroflex.swf} in the PDF document, and to display the SWF through +the rich media annotation. + +\subsection{Background} + +Version 9 of Acrobat/Adobe Reader introduces the \textit{rich media +annotation} which plays FLV movies, and SWF animations, and MP3 files.\footnote{% +The rich media annotation is introduced in +\textsl{Adobe Supplement to the ISO 32000}, which documents +BaseLevel 1.7, ExtensionLevel 3, the Adobe's extensions to PDF~1.7.} +Acrobat/Adobe Reader also provides a scripting bridge between +JavaScript for Acrobat, and ActionScript, the scripting language of +Flash player. This bridge enables the PDF and the Flash widget, +embedded in the rich media annotation, to communicate. The scripting +bridge opens up wonderful opportunities for applications to the +education sector. The {\AcroFLeX} Graphing Bundle is one such +application of the new PDF-Flash connection to education. + +\textbf{{\AcroFLeX}} uses the commercial product Adobe FLEX +Builder~3 and FLEX~3 SDK to produce Flash widgets, and the AeB to +create PDF documents with appropriate JavaScript to communicate with +the Flash widget. FLEX Builder~3 is currently free for students and +educators, the FLEX 3 SDK is free to all. + +% This style file defines some basic controls for +% \textbf{{\AcroFLeX} Graphing} for controlling graphical SWF files +% for graphing. +% +% These commands are general {\LaTeX} commands, that require no special driver, so +% they can be used by, for example, pdftex; however, we use SWF files to produce +% the graphing screen with the built-in ActionScript to communicate with the PDF. +% For this, you will need Acrobat 9 Pro. In that case, you might as well use the +% Acrobat Distiller to produce your PDF, but it is not necessary. + +\subsection{What is \texorpdfstring{{\AcroFLeX}}{AcroFLeX}?} + +The word \textbf{\AcroFLeX} is meant to convey a merging of two computer technologies: +\begin{itemize} +\item \textbf{Acro}: connotes both \textbf{Adobe Acrobat} (\textbf{Adobe Reader}) +and \textbf{{Acro\negthinspace\TeX}} (as in the +\textbf{{Acro\negthinspace\TeX} eDucation Bundle} or, just \textbf{AeB}). +\item \textbf{F\kern-.1667em\lower.5ex\hbox{L}\kern-.3eme\kern-.125emX\@}: connotes + \textbf{Adobe FLEX 3}. FLEX 3 is used to create SWF files to interact with the user. + In the case of graphing, plotting information is passed from Acrobat, via JavaScript, + to the Flash widget. ActionScript takes the data, and plots the points provided, and + connects them with a smooth curve. +\end{itemize} + + +\section{Requirements} + +In this section we list the requirements for this package. + +\subsection{{\LaTeX} Package Requirements} + +The preamble of the demo file afgraph.tex lists: +\begin{Verbatim}[xleftmargin=\amtIndent,numbers=left] +\usepackage[% + driver=dvips, + web={nodirectory,pro,tight,usesf}, + eforms,exerquiz,dljslib={ImplMulti}, + graphicxsp={showembeds} +]{aeb_pro} +\usepackage{acroflex} +\end{Verbatim} +Let me comment on each of these lines. +\begin{itemize} + \item Line~(7): Of course, we use the \pkg{acroflex} package. The + \pkg{acroflex} package \textit{requires} the \pkg{rmannot} package. + The latter package is the one that creates the rich media annotation, + embeds the graphing Flash widget, acroflex.swf, and displays it. The + \pkg{rmannot} package is the only one listed in \texttt{acroflex.dtx} + as required, however, more packages are really required, as discussed + in the next items. + + \item Lines (1)--(6): The \pkg{aeb\_pro} package is \textit{strongly + recommended}. The {\AcroFLeX} Graphing Bundle uses the + \texttt{willClose} environment to assure the document will behave + properly when the user closes the document. + + The options use the so-called \textbf{AeB Control Central} that represent + a convenient way to input the other required packages (in optimal order) + needed by the \pkg{acroflex} package. + + If \texttt{aeb\_pro} is not used, then the individual + required packages must be input using the \cs{usepackage} + mechanism. + + We input the \texttt{aeb\_pro} package before the + \pkg{acroflex} package. + + We now comment on each of the options used in the \texttt{aeb\_pro} + package: + \begin{description} + \item[Line (2), the \texttt{driver} option:] This system uses \app{Acrobat + Distiller}, which distills a PostScript file. The driver values + this package uses are \texttt{dvips} and \texttt{dvipsone}. + Setting the driver is important because the dvi-to-ps application + (\texttt{dvips} and \texttt{dvipsone}) consumes the dvi file + produced by the {\TeX} compiler and writes a PostScript file that + Acrobat Distiller consumes. + + \item [Line (3), the \texttt{web} option:] The \texttt{web} package + is not really required. It is used to create a PDF page size + convenient to view on a computer monitor. This package has many + options and features for the document author to design a document + for screen---or for paper---viewing. + + The \pkg{web} package brings in the \pkg{hyperref} package, which is + a \textit{required package}. If \texttt{web} is not used, + \pkg{hyperref} needs to be input. + + \item [Line (4), the \texttt{eforms} option:] A \textit{required} + package. This package provides form field and link support for + the {\AcroFLeX} Graphing Bundle. The \texttt{eforms}, in turn, + inputs the \texttt{insdljs} package, which provides support for + document-level JavaScript. It is the document-level JavaScript + where much of the work is done: parsing input, calculating + graphing data, and sending this data off to the + \texttt{acroflex.swf} widget for display. + + \item [Line (4), the \texttt{exerquiz} option:] A \textit{required} + package. The \texttt{exerquiz} package has several function + parsing methods defined in its document-level JavaScript. + {\AcroFLeX} uses these parsing routines. One of these days, I'll + separate out the parsing routines from \texttt{exerquiz}, but not + now. + + \item [Line (4), the \texttt{dljslib} option:] An optional, \emph{but + recommended} package. We use this package for its + \texttt{ImplMulti} option. This option simplifies the problem of + entering functional expressions. Without the \texttt{ImplMulti}, + to enter $2x\sin^2(2x)$, the user must type explicit + multiplications, \verb!2*x*(sin(2*x))^2!, with the + \texttt{ImplMulti} option, the user needs only enter + \verb!2xsin^2(2x)!. + + \item [Line (5), the \texttt{graphicxsp} option:] The \texttt{graphicxsp} is a + \textit{required} package of \pkg{rmannot}, but we input it + earlier so we can set its options through the \textbf{AeB Control + Central} (part of AeB Pro). The \texttt{graphicxsp} package, part + of the AeB Pro Bundle, provides embedding of poster graphics for + a rich media annotation. A poster graphic is the appearance you + see when the annotation is not activated. + + \end{description} +\end{itemize} + +\subsection{PDF Creator Requirements} + +This package requires Acrobat Distiller 9.0 (or later) to convert +PostScript files to PDF. Because this package uses \pkg{rmannot} +to create rich media annotations, there is also a requirement that +the Distiller must be opened using the \texttt{-F} command line +flag. See the documentation of the \pkg{rmannot} package for more +details. + +\subsection{Installation} + +The installation of the \pkg{acroflex} package is +straightforward. Place \texttt{acroflex.zip} in the search path of +your {\TeX} system and unzip. Unzipping creates a folder named +\pkg{acroflex}. Refresh your filename database, if your system +requires it. + +Accompanying the distribution is a file named \texttt{acroflex.cfg}. +Open this file in your favorite text editor and you see the +following lines. +\begin{Verbatim} + % + % AcroFleX Graphing Bundle Configuration File + % D. P. Story, dpstory@acrotex.net + % + \pathToAcroFlex{C:/acrotex/aebpro/acroflex/swf} +\end{Verbatim} +Edit the argument of \cs{pathToAcroFlex} (defined in the +\pkg{acroflex} package) to the path of the folder that contains +the \texttt{acroflex.swf} Flash file. Save and close +\texttt{acroflex.cfg}. + +Of course, you need to install the latest versions of AeB (the +{\AcroTeX} eDucation Bundle), AeB Pro, \texttt{graphicxsp}, and +\pkg{rmannot}. Follow the package documentation closely for +installation, some of the packages require that certain JavaScript +file be installed. + + +\section{The \texorpdfstring{\AcroFLeX}{AcroFLeX} Graphing System} + +This package defines several document scripts, the two primary ones are +\texttt{Graph\_xy()} and \texttt{Graph\_xyt()}, the others support these two. +\texttt{Graph\_xy()} and \texttt{Graph\_xyt()} take the data passed to it, +parse it, create plot data, and send it off to the {\AcroFLeX} graphing +widget to graph the data by way of the infamous scripting bridge. Details of +these functions can be found in the documentation in the +\texttt{acroflex.dtx} file. + +In the {\AcroFLeX} graphing system there are three modes of +operation: interactive, populate, and silent. +\begin{itemize} +\item \textbf{Interactive:} This occurs when the user enters a +function through the UI. + +The following controls are \emph{required}: +\begin{Verbatim} + \funcInputField, \graphBtn, \numPoints + \domMin, \domMax, \rngMin, \rngMax, +\end{Verbatim} +If parametric or polar graphs are to be used, +then \cs{domMinP} and \cs{domMaxP} are also required. The other +controls are \emph{optional}: +\begin{Verbatim} + \graphClrBtn + \amtShift (\hShiftL, \hShiftR, \vShiftD, \vShiftU) + \zoomInOut, \savedelSelBtn, \functionSelect +\end{Verbatim} +The \cs{graphClrBtn} button is recommended, though not required. +All these commands will be discussed in detail in the pages that follow. + +\item \textbf{Populate:} The populate mode occurs when the graphing + parameters are passed to \texttt{Graph\_xy} (or \texttt{Graph\_xyt}) by + \cs{sgraphLink} (or some other command). All the essential information + is passed as arguments. The target graphing screen has all the required + controls, as listed above. The command initiating the graphing must set + the \texttt{graph\_props.populate} property to \texttt{true}. In this + case the graphing data populate the required fields and the graph will + be drawn. It is the document author's responsibility to only use + populate on graphing screens that have all the required control fields. + + Populate behaves exactly like interactive, but the graphing data is + passed to the graphing routines in pre-packaged form, prepared by the + document author; the user, however, can manipulate the curve once it + appears. + + The required controls are the same as the interactive mode. + +\item \textbf{Silent:} In the silent or \emph{non-interactive} mode, there + must be no controls other than \cs{graphClrBtn}. Basically, the + document author prepares some pre-packaged graphs to be displayed to + the user, without interaction. These may go along with a tutorial + discussion symmetry, periodicity, tangent lines, etc. + + If the document author wants the user to interact with the graph, the + required controls need to be supplied and the + \texttt{graph\_props.populate} property needs to be set to \texttt{true}. + That is, use the populate mode. + +\end{itemize} + +\subsection{Setting up the Graphing Screen} + +It should be a hard and fast rule that all content concerning a +graphing screen should occur on the same page as the rich media +annotation that displays the graphing screen. Should discussion +cross page boundaries, create another graphing screen for that page. +Never fear, the {\AcroFLeX} graphing widget is only embedded once, +so adding more screens does not bloat the size of the file. + +There are three commands to set up an {\AcroFLeX} graph screen: +\Com{dimScreenGraph}, \Com{graphName} and \Com{graphScreen}. The use of +the command \cs{dimScreenGraph} is not required, but recommended. +\takeMeasure{\string\graphScreen[\meta{rma\_options}]\{\meta{width}\}\{\meta{height}\}} +\begin{dCmd}[commandchars=!()]{\wd\webtempboxi+2\fboxsep+2\fboxrule} +\dimScreenGraph{!meta(width)}{!meta(height)} +\graphName{!meta(unique_name)} +\graphScreen[!meta(rma_options)]{!meta(width)}{!meta(height)} +\end{dCmd} + +\CmdDescription We describe each of these three, and their parameters. +\begin{itemize} + \item \cs{dimScreenGraph}: This command is a convenient way of setting the dimensions + of the graphing screen. You specify the width of the screen using the \meta{width} + parameter and the height of the screen using the \meta{height} parameter. These values + are passed through a \cs{setlength}, so simple calculations on the dimension can be performed + on the parameters. (The \texttt{calc} package is used by the web package.) This command then + defines macros \Com{hScreenGraph} and \Com{vScreenGraph} to hold these two dimensions, respectively. + \cs{hScreenGraph} and \cs{vScreenGraph} can be used in \cs{graphScreen}, or in setting up + \texttt{minipage}s based on these lengths, for example. + + \item[] If the aspect ratio of all your graphing screens is going to be the same, then + it suffices to use \cs{dimScreenGraph} only once in the document. + + \item \cs{graphName}: Use this command to define a unique name for this graphing screen. Each + screen must have a different name. This command defines the text macro \Com{afgraphName}, which + expands to the given name. + + \item \cs{graphScreen}: This is the main command of this package, + it's the one that creates a rich media annotation and associates + it with the {\AcroFLeX} Graphing widget. It has three parameters: + %\begin{aebQuote} + \begin{description}\def\NH{\hspace{-\labelsep}} + \item \NH\meta{rma\_options} is optional and just passes to the underlying + command \Com{rmAnnot} (defined in the \pkg{rmannot} + package) that actually creates the rich media annotation. + The most ``important'' key-value pair, for this package, + is the \texttt{poster} key, through this key, a poster can + be associated with the annotation. + \item \NH\meta{width} is the width of the graph screen, if \cs{dimScreenGraph} was used, + just use \cs{hScreenGraph} as this value. + \item\NH\meta{height} is height the screen of the graph screen, if \cs{dimScreenGraph} was used, + just use \cs{vScreenGraph} as this value. + \end{description} +% \end{aebQuote} +\end{itemize} +The \cs{graphScreen} can be resized using \cs{resizebox} or +\cs{scalebox} (from the \texttt{graphicx} package) to obtain a +larger or smaller graph screen with the same aspect ratio. + + +The following is an example of the usage of each of these three commands. Note that the +height is three-fourths that of the width. + +\takeMeasure{\string\graphScreen[poster=aflogo]\{\string\hScreenGraph\}\{\string\vScreenGraph\}} +\begin{dCmd*}{\wd\webtempboxi+2\fboxsep+2\fboxrule} +\dimScreenGraph{186bp}{186bp*3/4} +\graphName{graph1} +\graphScreen[poster=aflogo]{\hScreenGraph}{\vScreenGraph} +\end{dCmd*} + +\paragraph*{Graphing Screen in a Floating Window.} The graphing +window can appear in a floating window as well. The +\Com{iconFloatGraphScreen} command is used to create such a screen. + +\takeMeasure{\string\iconFloatGraphScreen[\meta{key\_values}]\{\meta{width}\}\{\meta{height}\}} +\begin{dCmd}[commandchars=!()]{\wd\webtempboxi+2\fboxsep+2\fboxrule} +\iconFloatGraphScreen[!meta(key_values)]{!meta(width)}{!meta(height)} +\end{dCmd} +\PD The command has three parameters. The first optional one is passed as the +first optional parameter of the underlying \cs{graphScreen} command. The +\cs{graphScreen} command uses \Com{hScreenGraph} and \Com{vScreenGraph}, +defined through the \cs{dimScreenGraph} command, to set the dimensions of the +graph screen. The graph screen is then resized using \Com{resizebox} from the +\texttt{graphicx} package. The other two parameters, \meta{width} and +\meta{height}, are simply passed to \cs{resizebox}. See the documentation on +\cs{resizebox} for details on these parameters. + +For example,\takeMeasure{\string\iconFloatGraphScreen[poster=aflogo]\{40bp\}\{!\}} +\begin{dCmd*}{\wd\webtempboxi+2\fboxsep+2\fboxrule} +\iconFloatGraphScreen[poster=aflogo]{40bp}{!} +\end{dCmd*} +\noindent The first parameter is used to define a poster of the icon, the +second parameter is \texttt{40bp} which means to resize the graphic +to a width of \texttt{40bp}, the third parameter of exclamation +point (!) signals \cs{resizebox} to maintain the aspect ratio of the +graphic. + +The \cs{iconFloatGraphScreen} command is implemented by creating a +rich media annotation for the {\AcroFLeX} Graphing widget, with a +form field button on top of it that is transparent. Pressing on the +icon is actually pressing on the button. The button action activates +the graphing screen if it is not activated, and deactivates it if it +is activated. The graphing screen might be the target of graphing +data sent to it by the \cs{sgraphLink} command, see +\hyperref[sgraphlink]{Section~\ref*{sgraphlink}}, +page~\pageref*{sgraphlink}, or through the graphing screen controls, +these are explained next. + +\subsection{Graphing Screen Controls} + +The controls described in this section are used for interactive and +populate modes. + +\subsubsection{Required Controls} + +For interactive or populate mode, in addition to \cs{graphScreen}, +several controls are required so the user can manipulate the graph. + +\takeMeasure{\string\funcInputField[\meta{key\_values}]\{\meta{width}\}\{\meta{height}\}} +\begin{dCmd}[commandchars=!()]{\wd\webtempboxi+2\fboxsep+2\fboxrule} +\funcInputField[!meta(key_values)]{!meta(width)}{!meta(height)} +\end{dCmd} +\CmdDescription The field created by +\cs{funcInputField}\footnote{The command was originally misnamed +\cs{fileInputField} and is still recognized by the {\AcroFLeX} +package; however, document authors should use the command +\cs{funcInputField}.} is used to enter a function or a set of points +to be graphed. The function is parsed by the \texttt{exerquiz} +routines, so the same syntax that is used for \texttt{exerquiz} +quizzes and short quizzes is used. The \meta{key\_values} are +passed to the underlining text field and can be used to change the +appearance of the field, see the \texttt{eformman.pdf} for more +information. The \meta{width} and \meta{height} are the +width and height, respectively, of the text field. + +\takeMeasure{\string\graphBtn[\meta{key\_values}]\{\meta{width}\}\{\meta{height}\}} +\begin{dCmd}[commandchars=!()]{\wd\webtempboxi+2\fboxsep+2\fboxrule} +\graphBtn[!meta(key_values)]{!meta(width)}{!meta(height)} +\end{dCmd} +\CmdDescription The graph button.

The +parameters are the same as for \cs{funcInputField}, the descriptions +are the same. + + +\takeMeasure{\string\domMin[\meta{key\_values}]\{\meta{width}\}\{\meta{height}\}} +\begin{dCmd}[commandchars=!()]{\wd\webtempboxi+2\fboxsep+2\fboxrule} +\domMin[!meta(key_values)]{!meta(width)}{!meta(height)} +\domMax[!meta(key_values)]{!meta(width)}{!meta(height)} +\rngMin[!meta(key_values)]{!meta(width)}{!meta(height)} +\rngMax[!meta(key_values)]{!meta(width)}{!meta(height)} +\end{dCmd} +\CmdDescription The graphing window is set by these four text +fields. When the curve is graphed, only the rectangular window, +\begin{quote} +$[\,\cs{domMin}, \cs{domMax}\,] \times [\,\cs{rngMin}, +\cs{rngMax}\,]$ +\end{quote} +is displayed.\footnote {By this notation, I mean the +intervals determined by the values of these intervals.} The +parameters are the same as for \cs{funcInputField}, the descriptions +are the same. + +If parametric and polar graphing is required of the user, +\cs{domMinP} and \cs{domMaxP} are required as well. + +\takeMeasure{\string\domMinP[\meta{key\_values}]\{\meta{width}\}\{\meta{height}\}} +\begin{dCmd}[commandchars=!()]{\wd\webtempboxi+2\fboxsep+2\fboxrule} +\domMinP[!meta(key_values)]{!meta(width)}{!meta(height)} +\domMaxP[!meta(key_values)]{!meta(width)}{!meta(height)} +\end{dCmd} +\CmdDescription The interval $[\,\cs{domMinP}, \cs{domMaxP}\,]$ is +the interval over which a set of parametric equations is traced; in +the case of polar functions, this interval is used for the domain of +the polar function.

When this combo box is present, the user +is able to graph multiple curves and plots. Changing the combo box to +\texttt{Curve\,2}, for example, and pressing the \cs{graphBtn} button, the +function will be graphed on \texttt{Curve\,2}.

Curves are generated purely through +the user interface, that is, the user enters data into the various +form fields, clicks the \cs{graphBtn}, and \textsl{voil\`{a}}, the +graph is drawn! + +In this section, the populate mode is discussed as well as silent mode. + +\subsection{Graphing with \texorpdfstring{\protect\cs{sgraphLink}}{\CMD{sgraphLink}}}\label{sgraphlink} + +The document author can prepare function/points to be graphed, along +with all the essential data needed to view the graph. For populate, +the graphing data populate the required text field, and is available +for the user then to manipulate. The population of an interactive +graphing screen is done though a special link, the \cs{sgraphLink}. +(The ``s'' in \cs{sgraphLink} stands for ``silent,'' but that was +before I made the design decision to have a populate mode.) + +The syntax for \cs{sgraphLink} is +\takeMeasure{\string\sgraphLink[\meta{appr}]\darg{\meta{graph\_key\_vals}}% +\darg{\meta{func{\upshape|}points}}\darg{\meta{text}}} +\begin{dCmd}[commandchars=!()]{\wd\webtempboxi+2\fboxsep+2\fboxrule} +\sgraphLink[!meta(appr)]{!meta(graph_key_vals)}{!meta(func(!upshape|)points)}{!meta(text)} +\end{dCmd} +\PD The command takes four parameters, the first is the usual +optional parameter that can be used to change the appearance of the +link. The others we present in detail. +\begin{description} + \item [\texttt{[\meta{appr}]}:] Key-value pairs that are used to change the appearance of the link. + \item [\meta{graph\_key\_vals}:] Key-value pairs, some of which are used on the {\LaTeX} side, + some on the PDF side, while others on SWF side. + \begin{description} + \item\texttt{graph=\meta{value}}: The value of this key determines which + \emph{chart series} (FLEX terminology) the data will appear + on. The values of this key are: + \begin{description} + \item [\texttt{c1}, \texttt{c2}, \texttt{c3}, and \texttt{c4}:] + Use one of these values to graph a function, a polar function, + or a set of parametric functions. Up to four curves can be displayed + on the graphing screen at once. These values are displayed using + the \texttt{LinearSeries} (FLEX terminology). + \item [\texttt{a1}, \texttt{a2}, \texttt{a3}, and \texttt{a4}:] + Same as above, but the region between the horizontal axis, and + the graph is shaded in. These values are displayed using + the \texttt{AreaSeries} (FLEX terminology). + \item [\texttt{p1}, \texttt{p2}, \texttt{p3}, and \texttt{p4}:] + Use one of these values to plot points. These values are displayed using + the \texttt{PlotSeries} (FLEX terminology). + \end{description} + Thus, \texttt{graph=c2} tells the graphing + routines of {\AcroFLeX} and the {\AcroFLeX} Graphing widget + to display this data on series \texttt{c2}. + + If two curves or plots have the same value for + \texttt{graph}, then the one graphed last will + overwrite the earlier one. If you want both curves + or plots to appear on the graph together, give them + different \texttt{graph} values. + + When this key is not given a value, the default is + \texttt{c1}. + + \item [\texttt{type=\meta{\upshape{cart|para|polar}}}:] This key declares the type of curve, + possible values are \texttt{cart}, \texttt{para}, and + \texttt{polar}. This key is used mostly internally, and is + normally not used. There is one situation that it is used. When + defining a polar function, use \texttt{type=polar}. Thus, to + define a polar function, type something like this: + +\begin{Verbatim}[xleftmargin=\amtIndent,fontsize=\footnotesize] +\sgraphLink{type=polar,xInterval={[-1.5,1.5]},yInterval={[-1,2]}, + tInterval={[0,2*PI]},points=40,populate} + {1+sin(t)}{$r = 1 + \sin(\theta)$ } +\end{Verbatim} + + Note the explicit use of \texttt{type=polar}; the + parsing can identify a function of $x$ and a set of + parametric equations that are function of $t$, but help + is needed for polar. + + \item [\texttt{populate=\meta{\upshape{true|false}}}:] Possible + values are \texttt{true} or \texttt{false}, typing + \texttt{populate} is the same as \texttt{populate=true}. This + switch signals the graphing routines on the PDF side to populate + the required fields with the graphing data. The default is + \texttt{populate=false}, do not populate, use silent mode. + + \textbf{Populate versus Silent Modes:} The \texttt{populate} key + is how populate mode is distinguished from silent mode: + \texttt{populate=true} is populate mode, while \texttt{populate=false} + (or the populate parameter not listed) is silent mode. In + populate mode, the target graphing screen must have all required + control fields; in silent mode, the only control should be the + \cs{graphClrBtn} button. + + \item [\texttt{connectwith=\meta{\upshape{curve|segment}}}:] The key + determines the method used to connect consecutive points on the + graph, possible values are \texttt{curve} and \texttt{segment}. + This value is passed to the {\AcroFLeX} graphing widget. For + function of $x$, the default is \texttt{curve}; otherwise, the + default is \texttt{segment}. This value is ignored when the + \texttt{graph} property signals plotting + (\texttt{p1}--\texttt{p4}). + + \item [\texttt{points=\meta{num}}:] The number of points to generate for + plotting the current function. When the \texttt{graph} + property signals plotting (\texttt{p1}--\texttt{p4}), the + \texttt{points} property is ignored. If the graph property + signals graphing (\texttt{c1}--\texttt{c4}; + \texttt{a1}--\texttt{a4}), and argument \texttt{\#3} is a + set of rectangular points, the \texttt{points} property must + either not be present, or set to zero (\texttt{points=0}). + + \item [\texttt{xInterval=\darg{[a,b]}}:] (Required) An interval on the $x$-axis, the + interval must be in the form \verb!{[a,b]}!, for example, + \texttt{xInterval=\darg{[0,1]}}. For functions of $x$, this interval + represents the domain over which the function is graphed. It + also represents the left and right boundaries of the graphing + window. + + \textbf{Important:} The \texttt{xkeyval} package + parses these parameters. Because the interval notation + contains a comma (,), the whole interval must be enclosed in + braces so the parsing will be correct, as illustrated above. + + \item [\texttt{yInterval=\darg{[a,b]}}:] (Required) An interval on the $y$-axis, the + interval must be in the form \verb!{[a,b]}!, for + example, \verb!yInterval={[0,1]}!. It represents + the upper and lower boundaries of the graphing window. + + As with \texttt{xInterval}, the interval needs to be + enclosed in braces. + + \item [\texttt{tInterval=\darg{[a,b]}}:] When plotting a set of parametric equations, or + a polar function, this interval is required as a parameter. The + interval is of the form \verb!{[a,b]}!, including the braces, + and represents the domain of the parameter. The + \texttt{tInterval} must not be included otherwise, that is, for + graphing a function of $x$. Some early {\LaTeX} parsing tests + whether the value of \texttt{tInterval} is empty (the default) + or not. If nonempty, we assume the graphing is parametric or + polar. For point plotting, \texttt{tInterval} must not be + included in the parameter list. + + \item [\texttt{xPlot=\darg{[a,b]}}:] The parameter \texttt{xInterval} determines + the left and right boundaries of the graphing window; it also + determines the interval over which the function is to be plotted. + The \texttt{xPlot} separates these two functionalities; the value + of \texttt{xPlot} is an interval \verb![a,b]!, over which the + function will be plotted. Thus, \verb!xInterval={[-2,2]}! specifies + the scaling of the x-axis; while \verb!xPlot={[0,1]}! defines + the interval to plot the given function. If \texttt{xPlot} is not + specified, then \texttt{xInterval} will be used. + + \item [\texttt{noquotes=\meta{\upshape{true|false}}}:] When argument \texttt{\#3} is parsed, it + is, by default, placed in double quotes, for example, + \verb!"x^2"!; however, there are some situations where the + double quotes should not be used. (See the \texttt{afgraph.tex} + file for one such example.) Possible values for + \texttt{noquotes} are \texttt{true} and \texttt{false}. + Including \texttt{noquotes} in the option list is equivalent to + \texttt{noquotes=true}. The default is \texttt{noquotes=false}. + + \item [\texttt{wait=\meta{\upshape{true|false}}}:] Including + \texttt{wait} in the option list is equivalent to + \texttt{wait=true}. The default is \texttt{wait=false}. When + using \cs{defineGraphJS} to create a Java\-Script action that will + execute multiple calls to \texttt{Graph\_xy} or + \texttt{Graph\_xyt}, list \texttt{wait} in the option list. This + will cause a slight delay that allows the graphing screen to + become activated, (if not already activated) before the graphing + data is created and sent to the {\AcroFLeX} graphing widget. See + the example below in + \hyperref[defineGraphJS]{Section~\ref*{defineGraphJS}}, + page~\pageref*{defineGraphJS}. + \end{description} + \item [\meta{func{\upshape|}points}:] This argument can be a function or a set of points. + \begin{description} + \item [\meta{func}:] A function can be three types: (1) a function of $x$; (2) + a function of $t$; and a pair of function of $t$. If there is a + single function of $t$, case (2), that is interpreted as a polar + function, and graphed accordingly. The pair of functions must be + functions of $t$ and separated by a semi-colon (;); these are + then interpreted as a set of parametric equations. For example, + \verb!x^2! would be graphed as a parabola; \verb!1+sin(t)! would + be graphed as a Cardioid in the polar coordinate system; and + \verb!cos(t);sin(t)! would be graphed as a circle. + + \item [\meta{points}:] Points can be input as a semi-colon-delimited list of + rectangular coordinates. For example, \verb!(1,2);(2,3);(5,6)!. + Points can be plotted discretely, or plotted and connected with + either a smooth curve, or line segments. + \end{description} + \item [\meta{text}:] The text that the link is attached to, when + this text is clicked, the defined action of populating the graph + occurs. +\end{description} + +\subsection{Graphing with \texorpdfstring{\protect\cs{defineGraphJS}}{\CMD{defineGraphJS}}}\label{defineGraphJS} + +The \cs{defineGraphJS} command expands to either +\texttt{Graph\_xy()} or \texttt{Graph\_xyt()}, and is essentially +the code used by \cs{sgraphLink}.

As an English speaker, you can edit this file, and improve +the phrasing, if you wish. Specifying \texttt{german} as the value +of \texttt{lang} inputs the file \texttt{afcustom\_de.def}; you can, +of course, edit this file to get a preferred phrasing. If not lang +key-value pair is specified, the \textsf{acroflex} package inputs +the file \texttt{afcustom.def} (found in the examples folder). This +file is intended for local use. Place it in the folder where the +source file resides, modify it as desired to get custom messages. +The file \texttt{afcustom.def} contains some instructions and guidelines for editing. + +\redpoint If the file \texttt{afcustom.def} is placed on the latex search +path, it will be found and input for each source file; if +\texttt{afcustom.def} is in the source file folder, it is this +version that is found first and input. +Should the phrases entered in \texttt{afcustom.def} require special +accents, use the \texttt{unicode} option of \pkg{web} (which just +passes the \texttt{unicode} option on to \pkg{hyperref}), and enter any +special characters using {\LaTeX} notation.
