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 that string-type shows a graphical representation of data that uses color-coding to represent different values.

The setPaletteType() method is used to set the palette type. It takes string type values and does not return any value.

Syntax:

$('Selector').jqxHeatMap('setPaletteType','string');
