Welcome to Tableau! Tableau has a wealth of learning materials available online, as Prashant recommended. If you really want to use a book, these two are good:
- The Tableau manual at http://www.tableausoftware.com/support/help is a decent manual and you can learn a lot by reading it. It has some how-to, though it is more of a reference manual.
- Tableau Your Data! by Daniel Murray and the team at Interworks is less comprehensive than the Tableau manual but goes a deeper into how's and why's, more info at Tableau Your Data! | We wrote the book on Tableau. (Disclaimer: I contributed a case study for the book).
This forum thread also has a lot of good pointers on learning Tableau: How did you really learn Tableau?
Finally, be sure to set your expectations appropriately. Even though visualizations built in QV and Tableau could look very similar, QV and Tableau have extremely different approaches to working with data. There are definitely things that take a few seconds in QV that will be more work in Tableau, and vice versa. I'd suggest that you don't immediately try to duplicate QV apps because that will likely lead to immediate frustrations, rather take some time to learn how Tableau approaches data.
