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 colorMode property is used for setting or getting the rendering behavior of the sector of the specified jqxTreeMap. This property accepts three possible values that are illustrated below:

  • parent: This mode is used for a child sector inherits the color from its parent sector. Here color varies depending on the child’s value and the colorRange property.
  • autoColors: This mode is for automatic color generation depending on the baseColor, colorRange property, and the value.
  • rangeColors: For this mode, the user can set an array of color ranges. Here each color range is having properties such as min, max, and color.

Syntax:

  • For setting the colorMode property:

    $("#jqxTreeMap").jqxTreeMap({colorMode: 'autoColors'});  
  •  

  • For getting the colorMode property:

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