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 baseColor property is used for setting or getting the base color for the specified jqxTreeMap. This property is used when the value of the colorMode property is set to “autoColors”.

Syntax:

  • For setting the baseColor property:

    $("#jqxTreeMap").jqxTreeMap({baseColor: '#000000'});  
  •  

  • For getting the baseColor property:

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