CanvasJS Charts render and update huge data-sets in a matter of milliseconds without any performance lag. API is simple and easy to use. Given example shows Line Chart with 50000 data-points. It also includes PHP source code that you can try running locally.

  • PHP Code
<?php

$limit = 50000;
$y = 100;
$dataPoints = array();
for($i = 0; $i < $limit; $i++){
	$y += rand(0, 10) - 5; 
	array_push($dataPoints, array("x" => $i, "y" => $y));
}

?>
<!DOCTYPE HTML>
<html>
<head> 
<script>
window.onload = function () {
	
var data = [{
		type: "line",                
		dataPoints: <?php echo json_encode($dataPoints, JSON_NUMERIC_CHECK); ?>
	}];
	
//Better to construct options first and then pass it as a parameter
var options = {
	zoomEnabled: true,
	animationEnabled: true,
	title: {
		text: "Try Zooming - Panning"
	},
	axisY: {
		lineThickness: 1
	},
	data: data  // random data
};

var chart = new CanvasJS.Chart("chartContainer", options);
var startTime = new Date();
chart.render();
var endTime = new Date();
document.getElementById("timeToRender").innerHTML = "Time to Render: " + (endTime - startTime) + "ms";

}
</script>
<style>
	#timeToRender {
		position:absolute; 
		top: 10px; 
		font-size: 20px; 
		font-weight: bold; 
		background-color: #d85757;
		padding: 0px 4px;
		color: #ffffff;
	}
</style>
</head>
<body>
<div id="chartContainer" style="height: 370px; width: 100%;"></div>
<span id="timeToRender"></span>
<script src="https://cdn.canvasjs.com/canvasjs.min.js"></script>

Chart Customizations

Setting markerSize to zero in line / area charts enhances the performance of the chart with huge data sets. Some of the commonly used customization options include markerType, zoomType, zoomEnabled, etc.
