Last Updated : 25 Nov, 2021

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. jqxGauge represents a jQuery gauge widget, it is an indicator within a range of values. We can use Gauges to show a value in a range of values in the data region, there are 2 types of gauges: RadialGauge and LinearGauge. In RadialGauge, value is represented radially in a circular manner from some values.

The valueChanged event is triggered when the gauge’s value is changed.

Syntax:

$('#jqxGauge').bind('valueChanged', function (e) {
    // Code 
});
