This means that you can * choose the license that best suits your project and use it accordingly. * * See <GPL Version 2> and <MIT License> contained within this distribution for further information. * * The author would appreciate an email letting him know of any substantial * use of jqPlot. You can reach the author at: chris at jqplot dot com * or see http://www.jqplot.com/info.php. This is, of course, not required. * * If you are feeling kind and generous, consider supporting the project by * making a donation at: http://www.jqplot.com/donate.php. * * sprintf functions contained in jqplot.sprintf.js by Ash Searle: * * version 2007.04.27 * author Ash Searle * http://hexmen.com/blog/2007/03/printf-sprintf/ * http://hexmen.com/js/sprintf.js * The author (Ash Searle) has placed this code in the public domain: * "This code is unrestricted: you are free to use it however you like." * * * 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 = $.jqplot('targetElemId', [dataArray, ...], {title:'My Plot', axes:{yaxis:{min:20, max:100}}}); * * For more inforrmation, see <jqPlot Usage>. * * About: Usage * * See <jqPlot Usage> * * About: Available Options * * See <jqPlot Options> for a list of options available thorugh the options object (not complete yet!) * * About: Options Usage * * See <Options Tutorial> * * About: Changes * * See <Change Log> * */ (function($) { // make sure undefined is undefined var undefined; $.fn.emptyForce = function() { for ( var i = 0, elem; (elem = $(this)[i]) != null; i++ ) { // Remove element nodes and prevent memory leaks if ( elem.nodeType === 1 ) { $.cleanData( elem.getElementsByTagName("*") ); } // Remove any remaining nodes if ($.jqplot.use_excanvas) { elem.outerHTML = ""; } else { while ( elem.firstChild ) { elem.removeChild( elem.firstChild ); } } elem = null; } return $(this); }; $.fn.removeChildForce = function(parent) { while ( parent.firstChild ) { this.removeChildForce( parent.firstChild ); parent.removeChild( parent.firstChild ); } }; $.fn.jqplot = function() { var datas = []; var options = []; // see how many data arrays we have for (var i=0, l=arguments.length; i<l; i++) { if ($.isArray(arguments[i])) { datas.push(arguments[i]); } else if ($.isPlainObject(arguments[i])) { options.push(arguments[i]); } } return this.each(function(index) { var tid, plot, $this = $(this), dl = datas.length, ol = options.length, data, opts; if (index < dl) { data = datas[index]; } else { data = dl ? datas[dl-1] : null; } if (index < ol) { opts = options[index]; } else { opts = ol ? options[ol-1] : null; } // does el have an id? // if not assign it one. tid = $this.attr('id'); if (tid === undefined) { tid = 'jqplot_target_' + $.jqplot.targetCounter++; $this.attr('id', tid); } plot = $.jqplot(tid, data, opts); $this.data('jqplot', plot); }); }; /** * Namespace: $.jqplot * jQuery function called by the user to create a plot. * * Parameters: * target - ID of target element to render the plot into. * data - an array of data series. * options - user defined options object.
