  The body of the plotSet tag is executed in the scope of plotter. The body can contain nested "style" tags, one plotSetBar tag, and one "region" tag.

  One must specify number of plots to be plotted:"nplots" or "plots" attribute.

  Required attribute is "plots" that is  is a list of IManagedObjects to be plotted.  Each Each object from the list is plotted in a separate plotter region. 

  There are other optional plotSet attributes, with default values, e.g.:

        height = "600" 400 or 200*nX (pixels)
        width  = " 600 " or 300*nY (pixels)
        format = "png"
        var statusVar = "status" (object that keeps name of the variable that keeps PlotSetStatus object with the current status of the loop: index, region plots, ....)
        url = "" (The page to link the browser to)
        id = "" (The id for the browsing when multiple browsers are present in a page)
        allowDownload  = "true"
        createImageMap = "false"
        maxPlots = "9" (maximum number of plots per page)
        layout = "" (plot layout, must be in the form of nX x nY)

       Default layout:
        n Plots     nX x nY
          n<2         1x1
          n=2         1x2
      3<=n<5        2x2
      5<=n<7        2x3
      7<=n<10       3x3

 PlotSetStatus object has the following properties:

nplots, maxplots, plotsinpage, index, offset, offsetvariable, plots

plotSet can also contain the plotSetBar tag with the following attributes:

        url - required (The page to link the navigation bar to)

        var = "href" (name of the variable that keeps PlotSetBarStatus object with the current status of the bar hrefs: first, previous, last, ....)

PlotSetBarStatus object has the following properties that are filled with hrefs:

defaultBar, first, previous, next, last, pages

Examples:

1. Very simple example - just plot using defaults

...

<!--
    plot a set of IManagedObjects with a single
    regionplotter-level style
-->
<plotSet plots="${dataArray}">
    <style>
        .......
    </style>
</plotSet>

...

<!--
    plot a set of IManagedObjects with a different
    region-level styles
-->
<plotSet plots="${dataArray}" varstatusVar="status">   <region>
    <c:choose>
        <c:when test="${status.index%2 == 0}">
            <style>
                .......
            </style>
        </c:when>
        <c:otherwise>
            <style>
                .......
            </style>
        </c:otherwise>
    </c:choose>   <plot var="${dataAray[status.index]}"/>   </region>
</plotSet>

4. Plot data with two overlays, each uses different style

<!--
    plot a set of IManagedObjects with overlays and
    individual data styles
-->
<plotSet plots="${dataArray}" varstatusVar="status">
    <style>
        .......
    </style>
   <region>
    <plot var="${dataArray1[status.index]}">
        <style>
            .......
        </style>
    </plot>
    <plot var="${dataArray2[status.index]}">
        <style>
            .......
        </style>
    </plot></plot>region>
</plotSet>

5. Make regions clickable with unique href-s and styles

<!--
    plot a set of IManagedObjects with overlays.
    Make regions clickable and with unique styles.
    *** Seems that we need to set "href" by-hand, since tag
     *** itself knows only IManagedObjects, not paths to them
-->
<plotSet plots="${dataArray}" createImageMap="true" varstatusVar="status"> 
   <region title = "Region ${status.index}" href = .... >
       <plot var="${dataArray1[status.index]}">
           <style>
               .......
           </style>
       </plot>
       <plot var="${dataArray2[status.index]}">
           <style>
               .......
           </style>
       </plot>    </region>
</plotSet>
