*
* About: Introduction
*
* jqPlot requires jQuery (1.4+ required for certain features). jQuery 1.4.2 is included in the distribution.
* To use jqPlot include jQuery, the jqPlot jQuery plugin, the jqPlot css file and optionally
* the excanvas script for IE support in your web page:
*
* > <!--[if lt IE 9]><script language="javascript" type="text/javascript" src="excanvas.js"></script><![endif]-->
* > <script language="javascript" type="text/javascript" src="jquery-1.4.4.min.js"></script>
* > <script language="javascript" type="text/javascript" src="jquery.jqplot.min.js"></script>
* > <link rel="stylesheet" type="text/css" href="jquery.jqplot.css" />
*
* jqPlot can be customized by overriding the defaults of any of the objects which make
* up the plot. The general usage of jqplot is:
*
* > chart = $.jqplot('targetElemId', [dataArray,...], {optionsObject});
*
* The options available to jqplot are detailed in <jqPlot Options> in the jqPlotOptions.txt file.
*
* An actual call to $.jqplot() may look like the
* examples below:
*
* > chart = $.jqplot('chartdiv', [[[1, 2],[3,5.12],[5,13.1],[7,33.6],[9,85.9],[11,219.9]]]);
*
* or
*
* > dataArray = [34,12,43,55,77];
* > chart = $.jqplot('targetElemId', [dataArray, ...], {title:'My Plot', axes:{yaxis:{min:20, max:100}}});
*

* Properties:
