jQWidgets jqxTreeMap theme Property

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 theme property is used for setting or getting the theme of the specified jqxTreeMap.

Syntax:

For setting the theme property:

$('#jqxTreeMap').jqxTreeMap({ theme: "energyblue" });

For getting the theme property:

var showLegend = $('#jqxTreeMap').jqxTreeMap('theme');
