Hey All,
I have the code below that someone already helped me write from here.
It's not refreshing/updating the table on the webpage like it should. I
have validated that the data DOES update. Meaning it is a new and updated
DataTable object that is being passed to the DRAW method, but the chart on
the screen.
But, it never updates. It stays the same as the first load. And sometimes
it even crashes or shows an empty chart. My datasource can take 10 to 20
seconds to load sometime as this is a test rig, but I don't know why the
chart is plain crashing.
What have I done wrong?
<script type="text/javascript" src="//www.google.com/jsapi"></script>

<script type="text/javascript">
google.load('visualization', '1.1', { 'packages':
['annotationchart'] });
google.setOnLoadCallback(drawChart);
function drawChart() {
var chart = new
google.visualization.AnnotationChart(document.getElementById('chart_div'));
function updateChart() {
var jsonData = $.ajax({
url: "/ria/aceResponse.aspx?format=json",
dataType: "json",
async: false,
cache: false
}).responseText;
var interval = $.ajax({
url: "/ria/aceResponse.aspx?format=headerinterval",
dataType: "text",
async: false,
cache: false
}).responseText;
$("#interval").text(interval);
var data = new google.visualization.DataTable(jsonData);
chart.draw(data, {
is3D: true,
colors: ['red'],
displayZoomButtons: false,
displayRangeSelector: false,
dateFormat: 'HH:mm:ss'
});
}
updateChart();
setInterval(updateChart, 60000);
}
</script>
