Last Updated : 15 Nov, 2021

jQWidgets is a JavaScript framework for making web-based applications for PC and mobile devices. It is a very powerful and optimized framework, platform-independent, and widely supported. 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 LinearGauge, value is represented linearly in a vertical manner from some values.

The val() method is used to set the value to the jqxLinearGauge element. It does not return any value and takes the object containing the values as the parameter.

Syntax:

$('Selector').jqxLinearGauge('val', object);
