Chart.js Time Scale Sample

The following chart is from a sample I found in the samples/timeScale folder of Chart.js Github repository. As far as I understand, the bundle version of Chart.js should include the moment.js as well. But I could not make the following code to work, without adding the moment.js from a CDN.

If you now how to make the bundled version to work, without using moment.min.js, please let me know to update the code.





Using our plugin, named Blazing Charts, I added the following shortcode to this post:

[BlazingChart charttype="chartjs" source="a Chart Snippet" options="bundle"]

The script saved as a Chart Snippet is as following:

<script src="//cdnjs.cloudflare.com/ajax/libs/moment.js/2.13.0/moment.min.js"></script>
<style>
    canvas {
        -moz-user-select: none;
        -webkit-user-select: none;
        -ms-user-select: none;
    }
</style>
<div style="width:75%;">
	<canvas id="canvas"></canvas>

		function randomScalingFactor() {
			return Math.round(Math.random() * 100 * (Math.random() > 0.5 ? -1 : 1));

		function randomColor(opacity) {
