I have the code snippet shown below in my application . What I am trying to accomplish is this: anytime a checkbox is clicked, the bar chart should be updated. In my error console I'm getting: "Error: TypeError: values is undefined Source file:hit.js Line: 11017. I tried assigning the JSON directly in the function (var json = ...) and it works as it should but I can't get it to work by loading the JSON from the file. What am I doing wrong? <pre><code> $(':checkbox').click(function () { init(); function init() { var request = new XMLHttpRequest( ); request.open("GET", "GetGenes.php", false); request.send(null); var json = request.response; console.log(request.response); var barChart = new $jit.BarChart({ //id of the visualization container injectInto: 'infovis', //whether to add animations animate: true, //horizontal or vertical barcharts orientation: 'horizontal', //bars separation barsOffset: 0.5, //visualization offset Margin: { top: 5, left: 5, right: 5, bottom: 5 }, //labels offset position labelOffset:5, //bars style type:'stacked', //whether to show the aggregation of the values showAggregates:true, //whether to show the labels for the bars showLabels:true, //label styles Label: { type: 'HTML', //Native or HTML size: 9, family: 'Arial', color: 'black' }, //tooltip options Tips: { enable: true, onShow: function(tip, elem) { tip.innerHTML = "" + elem.name + ": " + elem.value; } } }); barChart.loadJSON(json); } }) </code></pre> genes.php contains: <pre><code>echo "{'label': ['label 1', 'label 2', 'label 3', 'label 4'],'values': [{'label': 'date A','values': [20, 40, 15, 5]}, {'label': 'date B','values': [30, 10, 45, 10]}, {'label': 'date E','values': [38, 20, 35, 17]}, {'label': 'date F','values': [58, 10, 35, 32]}, {'label''date D','values': [55, 60, 34, 38]}, {'label': 'date C','values': [26, 40, 25, 40]}]};"; </code></pre>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
