    Vishwas, i try this but not work, i’m sorry my js knowledge is not good, so can you give the example base on my code ? 

    <!DOCTYPE HTML>
<html>
<head>
<meta charset="utf-8"/>
<script type="text/javascript">
window.onload = function() {
	var dataPoints = [];
	var chart;
	$.getJSON("test.json", function(data) {  
		$.each(data, function(key, value){
			dataPoints.push({x: parseInt(value)[0], y: parseInt(value[1]), z: parseInt(value[2])});
		});
		chart = new CanvasJS.Chart("chartContainer",{
			title:{
				text:"Live Chart with dataPoints from External JSON"
			},
			data: [{
				type: "line",
				dataPoints : dataPoints,
			}]
		});
		chart.render();
		updateChart();
	});
	function updateChart() {
	$.getJSON("test.json" + (dataPoints.length + 1) + (dataPoints[dataPoints.length - 1].y) + function(data) {
		$.each(data, function(key, value) {
			dataPoints.push({
			x: parseInt(value[0]),
			y: parseInt(value[1]),
			z: parseInt(value[2])
			});
		});
		chart.render();
		setTimeout(function(){updateChart()}, 1000);
	});
	}
}
</script>
