About a month and half ago, we held our annual dashboard contest. This time the theme is to visualize state to state migration in USA. You can find the contest data-set & details here.
We received 49 outstanding entries for this. Most of the entries are truly inspiring. They are loaded with powerful analysis, stunning visualizations, amazing display of Excel skill and design finesse. It took me almost 2 weeks to process the results and present them here.

Outside of a dog, a book is a man’s best friend. Inside of a dog it’s too dark to read. -Groucho Marx
We don’t have a dog (yet), but we have a lot of books. Anytime I am in a bookshop, I feel like a mosquito in fat-camp. So you can imagine me smacking my lips when I saw your suggestions for favorite Excel books recently. There were more than 50 different books recommended by our readers. Of course I cannot buy all the 50 in one go. That would make Jo (my wife) angry. So I bought one that most of you recommended.
It is a book about array formulas, advanced formulas and data analysis techniques. I am eagerly waiting for the delivery to devour it. Once I am done with it, I will post a review here.
What about you? What Excel book are you reading now? Please share in comments.Continue »

The original template had tasks and completion check mark. As you finish each task, you can see the progress bar moving.
Peppe added priorities to this. With his new version, progress is measured based on how much priority we assigned that particular task. Pretty neat eh?!?Continue »
