ia.Thematic Class

Extends ia.EventDispatcher
Defined in: ia\thematics\Thematic.js:1
Module: ia

The ia.Thematic class is used to classify data. The Theme contains two classifiers for classifying both numeric and non-numeric data.

The data is an associative array with the following format:

["eh11"]{id:"eh11", name:"polwarth", value:2345, associate1:25}
["eh12"]{id:"eh12", name:"morningside", value:4347, associate1:45}
["eh13"]{id:"eh13", name:"merchiston", value:2496, associate1:25}
