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. The jqxTreeMap is used for showing the hierarchical data set of nested rectangles. Here each and every branch of the tree is represented as a rectangle, which is then tiled with smaller rectangles that represent sub-branches. Here the rectangle of the leaf node has an area proportional to a specified dimension on the data.

The colorRange property is used for setting or getting the range in which the base colors can vary for the specified jqxTreeMap. The value of this property ranges from 0 to 255. 

Syntax:

  • For setting the colorRange property:

    $("#jqxTreeMap").jqxTreeMap({colorRange: 125});
  •  

  • For getting the colorRange property:

    var colorRange = $('#jqxTreeMap').jqxTreeMap('colorRange');
