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 colorRanges property is used for setting or getting the color ranges for the specified jqxTreeMap. 

Syntax:

• For setting the colorRanges property:

  $('#jqxTreeMap').jqxTreeMap({ colorRanges: [
     { color: '#000000', min: 5,  max: 125  }
  ]
  });

 

• For getting the colorRanges property:

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