<html xmlns="http://www.w3.org/1999/xhtml">     <head>       <script type="text/javascript" src="http://www.google.com/jsapi"></script>       <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4/jquery.min.js"></script>       <script type="text/javascript" src="http://fancybox.net/js/fancybox-1.3.4/jquery.fancybox-1.3.4.js"></script>       <link rel="stylesheet" href="http://fancybox.net/js/fancybox-1.3.4/jquery.fancybox-1.3.4.css" type="text/css" media="screen" />        <script type="text/javascript">           google.load('visualization', '1', {packages: ['columnchart']});       </script>         <script>        function drawvisualization() {          var data = google.visualization.arraytodatatable([           ['year', 'sales', 'expenses'],           ['2004',  1000,      400],          ]);          var options = {           title: 'company performance',           haxis: {title: 'year', titletextstyle: {color: 'red'}}         };         // create , draw visualization.         new google.visualization.columnchart(document.getelementbyid('data')).draw(data, options);       }         $(document).ready(function() {         $("a#inline").fancybox({           'hideoncontentclick': true,           oncomplete: drawvisualization         });       });        </script>     </head>       <body>       <a id="inline" href="#data">show chart</a>       <div style="display:none"><div style='height:400px;width:600px' id="data"></div></div>     </body>   </html>

it's ugly...read on @ own risk !
seriously, it's not particularly elegant solution, might work (based on specific requirements, @ moment of writing not clear me).

you use custom data-* attribute (let's call data-chart-data) in each <a> element want display chart , store there serialized data.
(for illustration used simple scheme: separating table rows | , separating cell-data ,).)

<a href="#data" class="chartlink"          data-chart-data='"year","sales","expenses"|"2004",1000,400'>     show chart </a>

then, on js part, need pass chart-data parameter drawvisualization() function.

accessing chart-data (using html5): aelem.dataset.chartdata
accessing chart-data (no html5): aelem.getattribute("data-chart-data")

unfortunately, need custom function convert chart-data string representation js array. here sample function expects values of type integer (anything not enclosed in ") , string (anything enclosed in "):

function strtoarr(str) {     var arr = [];     var rows = str.split("|");     (var = 0; < rows.length; i++) {         var row = [];         var regex = new regexp("^\"(.*)\"$");         var values = rows[i].split(",");         (var j = 0; j < values.length; j++) {             var value = values[j].trim();             row.push(regex.test(value)                      ? regexp.$1                      : parseint(value, 10));         }         arr.push(row);     }     return arr; }

of course, should modify function cover needs.
in similar fashion, serialize "options" , pass them parameter drawvisualization() too.

see, also, short demo.
