jQWidgets is a JavaScript framework for making web-based applications for PC and mobile devices. It is a very powerful, optimized, platform-independent, and widely supported framework. The jqxBulletChart represents a jQuery bullet chart widget that features two measures, a primary one and a comparative one, and displays them in the context of a number of differently styled qualitative ranges.
The change event is triggered when the value is changed.
Syntax:
$('selector').on('change', function () { });
