Using a Timer
If you want to update your chart at regular intervals, you can using the functions previously discussed with the JavaScript window.setInterval function:
var myPieChart = rdGetChartCanvasObject('pieChart');
window.setInterval(function () {
myPieChart.rdUpdateChartData();
}, 3000);
The numeric value (3000 in our example) is the interval, which is expressed in milliseconds.
A script like this would be included using an Include Script element.
