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

The source property is used to set or return the source property. i.e. this property is used to set or return the item source. It accepts array type values and the default value is [].

Syntax:

  • It is used to set the source property.
    $('Selector').jqxHeatMap({ source : array});
  • It is used to return the source property.
    var source = $('Selector').jqxHeatMap('source');
