Hi,

I an trying to create a piechart but only the label shows but the chart is 
not displayed. Here is the link.

Here is the code-
<script type="text/javascript">
        google.load('visualization', '1.0', {'packages':['controls']});
        $(document).ready(function (){
            // Set a callback to run when the Google Visualization API is 
loaded.
            //alert("loaded");
            google.setOnLoadCallback(visualizebase);
            
            var vcffilename='vcf1';
            function visualizebase() {
                var jsonDataResult = $.ajax({
                        url:"getvcfvisualizeData.php",
                        data:{vcffilename:vcffilename,
                            visualtype:'base'},
                        dataType: "text",
                        async: false,
                        success: (
                        function(data) {
                            
                            //alert(data);
                            alert("loaded");
                            var tData = 
google.visualization.arrayToDataTable(eval(data));
                            // Create a dashboard.
                            var dashboard = new 
google.visualization.Dashboard(document.getElementById('dashboard_div'));
                            // Define a category picker for the 'Go Name'

                            //dashboard.bind(platformPicker, 
table).bind(platformPicker, altPicker).bind(altPicker, table);
                            dashboard.bind([platformPicker,altPicker], 
[logChart,table]).bind(platformPicker, altPicker);
                            
                            dashboard.draw(tData);
                            
                        })
                });
            }
           
        });
    </script>

Please help.
I also needed help with grouping the 3,4 columns together to get the counts 
and show in some kind of chart


Thanks
