Reply To: Dynamic Chart Using Data From JSON File

[Vishwas R]

Sandonet,

You seem to be passing wrong parameters to getJSON. Replacing
$.getJSON("test.json" + (dataPoints.length + 1) + (dataPoints[dataPoints.length - 1].y) + function(data)
with
$.getJSON("test.json", function(data) { in updateChart function should work fine. Please find the working code below.

function updateChart() {
	$.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.render();
		setTimeout(function(){updateChart()}, 1000);
	});
}
