Once you have installed it, use the Inspector to find out how COGNOS renders HTML, and some of the attributes it uses to uniquely identify elements. You’ll notice that rows of information get a UID, which you can use to create all sorts of custom charts and data through API’s like Google Charts.

Here’s an important one that I discovered – give it a shot in console.
