    <p>I've got a problem with the visualization of data with google's charts api after an ajax call.</p> <p>First I made an ajax call and fetched a json object. After that I want to extract some data out of the json and draw a gauge chart. Getting the json and extracting the data works fine, but when I try to load the chart, the body gets removed and I get a blank/white screen. Does anyone knows what I am doing wrong? I also tried to hard code values for the chart instead of taking the json values (but kept the ajax call before loading the chart), but it didn't work neither.</p> <pre><code>function loadStats(){ var http = getRequestObject(); var city = "berlin"; http.open("GET", "getTwitterSentiments.php?city="+city, true); http.onreadystatechange=function() { getStatistic(http) }; http.send(null); } function getStatistic(request) { if ((request.readyState == 4) &amp;&amp; (request.status == 200)) { var data = request.responseText; var JSONStats = eval("(" + data + ")"); loadGauge(JSONStats.sentiment_index); } function loadGauge(sentiment){ google.load('visualization', '1', {packages:['gauge']}); google.setOnLoadCallback(drawGauge); function drawGauge() { var data = google.visualization.arrayToDataTable([ ['Label', 'Value'], ['Test', sentiment] ]); var options = { width: 100, height: 100, redFrom: 0, redTo: 45, yellowFrom: 45, yellowTo: 55, greenFrom: 55, greenTo: 100, minorTicks: 10 }; var chart = new google.visualization.Gauge(document.getElementById('testgchart')); chart.draw(data, options); } } </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.
