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 height property is used for setting or getting the height of the specified jqxTreeMap. This property accepts numeric values.

Syntax:

  • For setting the height property:

    $('#jqxTreeMap').jqxTreeMap({height: 100});
  •  

  • For getting the height property:

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