%    \section{The Examples}
%    This \textsf{DTX} file contains the source files for the examples of the \pkg{bargraph-js} package.
%    It has the added advantage of enabling me to provide verbose comments without messing up
%    the source files.
%    \begin{macrocode}
%</package>
%<*basic1>
%    \end{macrocode}
%    \subsection{\texttt{bgjs-basic1.tex}}
%    This is a minimal example, it
%    illustrates the basic capability of the package: horizontal and vertical bars are shown.
%    \begin{macrocode}
\documentclass{article}
%    \end{macrocode}
%    Use of the \pkg{web} package is optional, my favorite package. If loaded, you can remove
%    |\hypersetup{pdfpagemode=UseNone}| below, as \pkg{web} does not show the bookmarks by default.
%    \begin{macrocode}
 % \usepackage{web}
%    \end{macrocode}
%    Input ``the package''
%    \begin{macrocode}
\usepackage{bargraph-js}
\hypersetup{pdfpagemode=UseNone} % don't need to see bookmarks
%    \end{macrocode}
%    When developing the document use |\previewOn\pmpvOn|, the latter command is new (to \pkg{eforms}). It provides
%    captions for the buttons. With this combination, outlines of form fields and captions for
%    push buttons are seen in \app{SumatraPDF}, for example.
%    \begin{macrocode}
 % \previewOn\pmpvOn
%    \end{macrocode}
%    For the \pkg{bargraph-js} package, I prefer to specify |\makePDasXon| (from \pkg{eforms}), this attempts to make
%    the dimensions of form fields correspond to the true dimensions, as \app{xelatex} does.
%    \begin{macrocode}
\makePDasXOn
%    \end{macrocode}
%    Below is ``sample'' document JavaScript to provide labeling to bars that do not have
%    a |\TU| key specified (tool tip). There is a default labeling system, this overwrites
%    that.
%    \begin{macrocode}
\begin{insDLJS}{lbl}{Labeling function}
%%   fld="<bgenv-name>@<bg-name>.<bar-name>"
%%   v=value of field
function customLabelsForBars(fld,v){
var pos=fld.indexOf(".");
var bargraph=fld.substring(0,pos);
var bar=fld.substring(pos+1);
  switch(bargraph) {
    case "vehiclesH@hBar":
      switch(bar) {
        case "auto":
          return "Automobiles: "+v;
        case "truck":
         return "Pickup trucks: "+v;
        case "suv":
          return "SUV types: "+v+", costing big \$\$s";
        case "van":
          return "Family vans: "+v
            +", these cost some serious \u20AC\u20ACs";
        default:
          return simpleBarLabels(fld,v);
      }
// other cases can be included
    default:
      return simpleBarLabels(fld,v);
  }
}
\end{insDLJS}
%    \end{macrocode}
%    The \DescribeMacro\barLabelsTU\cs{barLabelsTU} takes either a string argument or a JavaScript function name.
%    \cs{barLabelsTU} applies to all bars with a \cs{TU} key. The \cs{barLabelsTU} can be used within the body of
%    the document to change the method of assigning labels to bars. When the argument is a (JavaScript) string,
%    use the variables \texttt{@env@}, \texttt{@barname@}, \texttt{@bar@}, and \texttt{@v@}
%    to compose the string, as seen below. When a string is provided, \emph{the \cs{TU} key is ignored}.
%    \begin{macrocode}
 % \barLabelsTU{"Within the \\"@env@\\" environment, within the
 %   \\"@barname@\\" environment, the bar \\"@bar@\\"
 %   has a value of @v@"}
%    \end{macrocode}
%     When the argument is a JavaScript function, you can specify the built-in function
%     \texttt{customBarLabels}, or define your own. The function is expected to take two
%     arguments, fld and v, eg, \texttt{customBarLabels(fld,v)}. Such a function should return
%     a string.
%    \begin{macrocode}
\barLabelsTU{customBarLabels} % applies to all bars with a \TU key
%    \end{macrocode}
%    The \DescribeMacro\barLabelsNoTU\cs{barLabelsNoTU} takes a string or a function as its argument.
%    The command \cs{barLabelsNoTU} is specified in the preamble and cannot be changed in the body of the document.
%    This labeling system applies to all bars with no \cs{TU} key.
%    When the argument is a string, use \texttt{o.barname}, \texttt{o.bar}, and \texttt{o.value} to compose
%    the string. For example,
%    \begin{macrocode}
 % \barLabelsNoTU{"Vehicle Data: "+o.barname+": "
 %    + o.bar+", Value: "+o.value}
%    \end{macrocode}
%     When the argument is a JavaScript function, the referenced function must be written. In this demo,
%     \texttt{customLabelsForBars(fld,v)} is reference below; however, we choose the default, which
%     is |\barLabelsNoTU{""}| (or |barLabelsNoTU{}|). The results are the same; however, the difference
%     is that you can write your own handler.
%    \begin{macrocode}
\barLabelsNoTU{customLabelsForBars} % applies to all other bars

\textbf{Comments.} The bar graphs here are based on count data.
Input natural numbers into the text fields. If the width of a horizontal
bar or the height of a vertical bar goes outside the graphing area, the
bar graph is \emph{automatically re-scaled} so the widest one (for
horizontal) or highest one (for vertical) now fits. Try the
\textsf{Optimize} buttons as well.\medskip

\textbf{Instructions:} Stand at an intersection for one hour and count
the number of vehicles of each of the specified types passing you going
in one direction. Enter your results in the fields below.\medskip

In this example, we label the bar graph using text fields (using the

initially hidden, then made visible when data is entered into the
input fields.\par\medskip
