+\section{Introduction}
+
+The \textbf{{\AcroFLeX}} Graphing Bundle is used to create a
+\emph{graphing screen} that can be incorporated into a PDF document
+and viewed within \app{Adobe Acrobat Reader}, version 9.0 or later. 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. Once the user has entered a
+required data into the required fields, the user press this button
+and the graph appears in the graph screen. The parameters are the
+same as for \cs{funcInputField}, the descriptions are the same.
+
+\takeMeasure{\string\numPoints[\meta{key\_values}]\{\meta{width}\}\{\meta{height}\}}
+\begin{dCmd}[commandchars=!()]{\wd\webtempboxi+2\fboxsep+2\fboxrule}
+\numPoints[!meta(key_values)]{!meta(width)}{!meta(height)}
+\end{dCmd}
+\CmdDescription This text field displays the number of points to be
+plotted. It is editable, the user can change this value. 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. The parameters are the same as for
+\cs{funcInputField}, the descriptions are the same.
+
+\paragraph*{Setting the default values.} Whereas it is possible to
+set the default values of the fields just described, a more
+convenient method is used.
+
+\takeMeasure{\string\defaultDomRng%
+\{\meta{x\_min}\}\{\meta{x\_max}\}\{\meta{y\_min}\}\{\meta{y\_max}\}}
+\begin{dCmd}[commandchars=!()]{\wd\webtempboxi+2\fboxsep+2\fboxrule}
+\defaultFunction{!meta(!upshape(function|points))}
+\defaultNumPoints{!meta(postive_integer)}
+\defaultDomRng{!meta(x_min)}{!meta(x_max)}{!meta(y_min)}{!meta(y_max)}
+\defaultDomP{!meta(t_min)}{!meta(t_max)}
+\end{dCmd}
+
+\noindent These can be executed, along with \cs{graphName}, just before the
+\cs{graphScreen} command. The values of their parameters will then populate
+the corresponding fields as default values.
+
+The following are the default values of all the required fields, as
+defined by the \pkg{acroflex} package. Note that all of these are
+parsed (with the exception of the number of points) using
+\texttt{exerquiz}'s parsing routines; consequently, a value such as
+\texttt{2*PI} is perfectly legal.
+
+\takeMeasure{\string\defaultDomRng\darg{-2}\darg{2}\darg{0}\darg{4}}
+\begin{dCmd*}{\wd\webtempboxi+2\fboxsep+2\fboxrule}
+\defaultFunction{x^2}
+\defaultNumPoints{40}
+\defaultDomRng{-2}{2}{0}{4}
+\defaultDomP{0}{2*PI}
+\end{dCmd*}
+
+\subsubsection{Optional Controls}
+
+There are several other optional controls that may be useful in manipulating
+a graph.
+
+\takeMeasure{\string\graphClrBtn[\meta{key\_values}]\{\meta{width}\}\{\meta{height}\}}
+\begin{dCmd}[commandchars=!()]{\wd\webtempboxi+2\fboxsep+2\fboxrule}
+\graphClrBtn[!meta(key_values)]{!meta(width)}{!meta(height)}
+\end{dCmd}
+On clicking this button, the current graphing screen is cleared of
+all graphs and plotted points. Shift-clicking this button
+deactivates the graphing screen, and the annotation's poster
+appears.
+
+\paragraph*{Multiple Plots.} By using the \Com{functionSelect} combo
+box, the user can graph multiple curves.
+
+\takeMeasure{\string\functionSelect[\meta{key\_values}]\{\meta{width}\}\{\meta{height}\}}
+\begin{dCmd}[commandchars=!()]{\wd\webtempboxi+2\fboxsep+2\fboxrule}
+\savedelSelBtn[!meta(key_values)]{!meta(width)}{!meta(height)}
+\functionSelect[!meta(key_values)]{!meta(width)}{!meta(height)}
+\end{dCmd}
+The \cs{functionSelect} combo box serves several purposes. It consists of
+eight items that appear as \texttt{Curve\,1}, \texttt{Curve\,2},
+\texttt{Curve\,3}, \texttt{Curve\,4}, \texttt{Plot\,1}, \texttt{Plot\,2},
+\texttt{Plot\,3}, \texttt{Plot\,4}. 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}. There are four curves possible,
+and four sets of plotted points. The different curves and plots are color
+coded.
+
+When the \cs{savedelSelBtn} is also present, the user can click on
+it and save the function definition under that curve or plot. These
+expressions will only be saved during the current viewing session in
+\app{Acrobat Reader}, but if the user is on Acrobat, the PDF can be saved
+and the values added to the combo list will be saved as well.
+
+The parameters are the same as for
+\cs{funcInputField}, the descriptions are the same.
+
+\paragraph*{Horizontal and Vertical Shifting.} There are several
+controls that shift the graphing window vertically or horizontally.
+
+\takeMeasure{\string\amtShift[\meta{key\_values}]\{\meta{width}\}\{\meta{height}\}}
+\begin{dCmd}[commandchars=!()]{\wd\webtempboxi+2\fboxsep+2\fboxrule}
+\amtShift[!meta(key_values)]{!meta(width)}{!meta(height)}
+\hShiftL{!meta(text)}
+\hShiftR{!meta(text)}
+\vShiftU{!meta(text)}
+\vShiftD{!meta(text)}
+\end{dCmd}
+The \cs{amtShift} is a text field, its value is a positive number
+that will be used to shift the graphing window horizontally or
+vertically. The user can change this value. The parameters are the
+same as for \cs{funcInputField}, the descriptions are the same.
+
+The other four commands are implemented as links, then clicked, the
+graphing window moves the amount specified in \cs{amtShift} field
+left (\cs{hShiftL}), right (\cs{hShiftR}), up (\cs{vShiftU}) or down
+(\cs{vShiftD}). The argument \meta{text} is the text to be used
+to identify the link.
+
+\paragraph*{Zoom, zoom, zoom.}
+
+The user can be allowed to optionally zoom the graph out or in by providing the
+control \Com{zoomInOut}.
+
+\takeMeasure{\string\zoomInOut[\meta{key\_values}]\{\meta{width}\}\{\meta{height}\}}
+\begin{dCmd}[commandchars=!()]{\wd\webtempboxi+2\fboxsep+2\fboxrule}
+\zoomInOut[!meta(key_values)]{!meta(width)}{!meta(height)}
+\end{dCmd}
+Click the \cs{zoomInOut} button zooms out by an amount shown in the
+\cs{amtShift} field; shift-clicking will zoom in by the amount shown
+in the \cs{amtShift} field. The parameters are the same as for
+\cs{funcInputField}, the descriptions are the same.
+
+\paragraph*{Setting the default values.} As with the required controls, the optional ones
+can be given default values through convenience macros.
+
+
+\takeMeasure{\string\defaultShiftAmt\darg{\meta{positive\_number}}}
+\begin{dCmd}[commandchars=!()]{\wd\webtempboxi+2\fboxsep+2\fboxrule}
+\defaultShiftAmt{!meta(positive_number)}
+\defaultShiftAmt{1}
+\end{dCmd}
+The \cs{defaultShiftAmt} is used to set the default value of the \cs{amtShift} field; the default
+value is \cs{defaultShiftAmt\darg{1}}.
+
+The \cs{functionSelect} lists four curves and four plots. The text can be changed by
+through the following text macros. Each command is followed by its default definition.
+\takeMeasure{\string\afCurve\darg{\meta{name\_for\_curve}}}
+\begin{dCmd}[commandchars=!()]{\wd\webtempboxi+2\fboxsep+2\fboxrule}
+\afCurve{!meta(name_for_curve)}
+\afCurve{Curve}
+\afPoint{!meta(name_for_point)}
+\afPoint{Point}
+\afUnused{!meta(unused)}
+\afUnused{--unused}
+\end{dCmd}
+The definitions values of \cs{afCurve} and \cs{afPoint} are the
+target of several search using regular expressions. If the values of
+\cs{afCurve} and \cs{afPoint} are too complex, the regular
+expression search may fail. Try to keep these definitions to ASCII
+characters.
+
+\subsection{Populate and Silent Linking}
+
+The previous section details the interactive mode, where the
+\cs{graphScreen} is present with all its required controls, and
+possibly some optional controls. 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}. Use \cs{defineGraphJS} to create a
+custom link action or form field action to graph pre-packaged
+functions.
+
+\takeMeasure{\string\defineGraphJS\darg{\meta{graph\_key\_vals}}\darg{\meta{func{\upshape|}points}}\darg{\meta{command}}}%
+\begin{dCmd}[commandchars=!()]{\wd\webtempboxi+2\fboxsep+2\fboxrule}
+\defineGraphJS{!meta(graph_key_vals)}{!meta(func(!upshape|)points)}{!meta(command)}
+\end{dCmd}
+
+\CmdDescription \cs{defineGraphJS} defines a new command
+\cs{\meta{command}} what will expand to \texttt{Graph\_xy()} or
+\texttt{Graph\_xyt()} fully populated by its arguments. This command
+can be used to create new actions that involve multiple calls to the
+{\AcroFLeX} graphing routines.
+
+\PD There are three required parameters.
+\begin{description}
+ \item [\meta{graph\_key\_vals}:] The same key-value pairs as
+ described for \cs{sgraphLink}.
+ \item [\meta{func{\upshape|}points}:] An expression representing a
+ function of $x$, a polar function of $t$, a set of parametric
+ equations, or a set of points.
+ \item [\meta{command}:] A command that this JavaScript code will
+ be saved under.
+\end{description}
+
+An example of usage can be found in \texttt{afgraph.tex}, we
+present another example here, also included in \texttt{afgraph.tex}, that
+might suggest the value of this command. We construct a link that
+graphs a function and plots discrete points.
+
+\begin{Verbatim}[fontsize=\footnotesize,xleftmargin=\amtIndent]
+\def\DomX{[0,2PI]}\def\DomY{[-1,1]}
+\defineGraphJS{graph=c1,wait,xInterval={\DomX},yInterval={\DomY},
+ points=40}{sin(x)}{\mySineCurve}
+\defineGraphJS{graph=p1,wait,xInterval={\DomX},yInterval={\DomY}}
+ {(0,sin(0));(PI/2,sin(PI/2));(PI,sin(PI));(3PI/2,sin(3PI/2));
+ (2PI,sin(2PI))}{\mySinePoints}
+\setLinkText[\A{\JS{%
+ \clearGraphJS\r
+ \mySineCurve\r
+ \mySinePoints
+}}]{Consider the sine function and indicated points}%
+\end{Verbatim}
+Note the use of the \texttt{wait} key in both the definitions to give the graphing screen
+time to be activated and ready to receive data. Observe also the list of points is given
+in symbolic form, we let JavaScript calculate the values for us.
+
+The command \Com{clearGraphJS} is used to clear the graphing screen before new curves are written
+to the screen. \cs{clearGraphJS} expands to the document JavaScript function that clears
+the graphing screen.
+
+\section{Customizations}
+
+There are a number of English phrases that appear as tooltips or as
+messages in alert dialog boxes, as a result, the acroflex package has
+a language option.
+\takeMeasure{\string\usepackage[lang=english|german]\darg{acroflex}}%
+\begin{dCmd}[commandchars=!()]{\wd\webtempboxi+2\fboxsep+2\fboxrule}
+\usepackage[lang=english|german]{acroflex}
+\end{dCmd}
+Specifying \texttt{english} as the value of \texttt{lang} inputs the
+file \texttt{afcustom\_us.def}, which normally does nothing; the
+definitions made in this file are the hard-wired defaults of the
+package. 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. For example, to address
+my formerly favorite friend, J\"{u}rgen, we can write,
+\begin{Verbatim}[xleftmargin=\amtIndent]
+\ttgraphBtn{J\"{u}rgen, press to graph the function}
+\end{Verbatim}
+For the alert box messages, use JavaScript unicode notation, for example
+\begin{Verbatim}[xleftmargin=\amtIndent]
+\flJSStr{\af@badNumberMsg}{%
+ J\u00FCrgen, the value input does not appear to be a number,
+ please enter a number, or an expression that evaluates to a
+ number. \dps}
+\end{Verbatim}
+This latter example does not require the \texttt{unicode} option.
+
+
+\newtopic Note that \cs{flJSStr} is a new command (defined in \pkg{insdljs}) that enables you
+to enter unicode, for example, \cs{u00FC} is the u-umlaut (\verb!\"{u}! or
+\"{u}). Also, within the argument string, you can use \cs{r} (carriage
+return) and \t (tab) to format your lines as needed. Double backslash
+\verb!\\! is converted into single backslash \verb!\!, so for example,
+\verb!\\AcroTeX! appears in the dialog box as \cs{AcroTeX}. The string
+argument is immediately expanded, so a command like \cs{dps} (in the above
+definition) gets expanded at definition time. Use \cs{protect} to delay the
+expansion until the tex compiler finally expands the JS command string
+(useful here, if \cs{dps} gets redefined).
+
+
+
+\bigskip\noindent
+That's all for now, I simply must get back to my retirement. \dps
