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. The jqxHeatMap represents a jQuery widget which shows a graphical representation of data that uses color coding to represent different values..

The destroy() method is used to destroy the jqxHeatMap. It does not accept any parameter and does not return any value.

$('Selector').jqxHeatMap('destroy');
