Hey all, I am using the following Javascript. But, it causing the chart to
BREAK badly on each update.
What have I done wrong?
<script type="text/javascript">
google.load('visualization', '1.1', { 'packages':
['annotationchart'] });
google.setOnLoadCallback(drawChart);
setInterval(drawChart, 10000);
function drawChart() {
var jsonData = $.ajax({
url: "/data/aceResponse.txt",
dataType: "json",
async: false,
cache: false
}).responseText;
var interval = $.ajax({
url: "/data/IntervalRequest.txt",
dataType: "text",
async: false,
cache: false
}).responseText;
$("#interval").text(interval);
var data = new google.visualization.DataTable(jsonData);
var chart = new
google.visualization.AnnotationChart(document.getElementById('chart_div'));
chart.draw(data, {
is3D: true,
colors: ['red'],
displayZoomButtons: false,
displayRangeSelector: false,
dateFormat: 'HH:mm:ss'
});
}
