Agenda

Anscombe’s Quartet was constructed by statistician Francis Anscombe in 1973

How do I interpret this data?

Statistical Properties:• Mean• Variance• Correlation• Linear Regression

* Anscombe, F. J. (1973). "Graphs in Statistical Analysis". American Statistician

The same across all four datasets!

Value of Data Visualizations

* Anscombe, F. J. (1973). "Graphs in Statistical Analysis". American Statistician

Anscombe’s Quartet

• Graphs should be telling a story that people understand

• Choose the best way to convey the message of the story

Here’s an example of a real life situation explained by a visualization:

• Wordle.net was created by Jonathon Feinberg, which he now owns and operates for non-commercial purposes

• “a toy for generating ‘word clouds’ from text that you provide.”

RAVE Visualization created using Cognos

Overview of RAVE

What is RAVE?

• RAVE stands for Rapidly Adaptive Visualization Engine, which is an IBM technology that drives data visualizations using a JavaScript grammar based language called JSON

• JavaScript Object Notation• Simpler than XML• Better suited to data-interchange• Lightweight, less grammar

What is JSON?

Overview of RAVE

• The Visualization object became available with Cognos version 10.2 • New chart types• Updates to existing chart types• Improved animation and interactivity• Visualization customizer application• Charts can be added into solution without waiting for Cognos release

How do I use Visualizations?

• From a user’s perspective, RAVE Visualizations are seamlessly integrated into Cognos Reports (show comparisons)

From a developer’s perspective, using a Visualizations is simply picking another tool in the toolbox

Functionality is similar to standard chart object

Demo: Look at Visualization object in Report Studio

How do I install Visualizations?

Download new visualizations from AnalyticsZone.com

• New Library tab in the Admin panel (Cognos 10.2)

• New “Library Administrators” role

From Library tab, click “Import Visualizations…” and browse for the file

Now the new Visualization is available for the developer.

How do I update a Visualization?

Demo: Updating a visualization in the editor
