Analyzing Data with Power View (Level 100) Jen Stirrup Come learn about the best ways to present data to your Business Intelligence data consumers, and see how to apply these principles in Power View, Microsoft's data visualization tool. Using demos, we will investigate Power View based on current cognitive research around data visualization principles from such experts as Stephen Few, Edware Tufte, and others. We will then examine how data can be analyzed with Power View and look at where Power View is supplemented by other parts of the Microsoft Business Intelligence stack.

3. Data Visualisation and Power View
We have the tools. All we’ve got to
do is imagine what could be.
We can reinvent the present;
we can transform the world around us.

7. Data Visualisation and Power View
Power View does not contain 3D functionality – why?
People can overestimate the vertical dimension (Wansink, 2003)
3D space makes it too difficult to compare
• Values
• Volumes
• Areas
Distorts

8. Pie Charts and Power View

We find it difficult to read angles
We find it difficult to judge areas
We can’t easily read over 5 slices very well
Each part must be mutually exclusive

9. Pie Charts – the Verdict!
You can compare combinations of adjacent wedges
The parts should make a sensible whole
You’re just expecting the image to answer one ‘business
question’ only
You do not need trendlines
