This is the first in a series of challenges for those that believe they have mastered the more complicated aspects of Tableau. The series will call on your understanding of the intricacies of how Tableau functionality works.

For example, did you know that you can perform merchandising affinity analysis using dynamic sets? Did you know that forecasting in Tableau uses the exponential smoothing technique, and do you know how that affects the results of the forecast? Did you know that when using non-additive computations or LOD expressions that reference a secondary data source you may need to have the linking field from the primary data source in the view?

If these questions are news to you, then you may be interested in trying out our Tableau Master Challenge series. We will explore some new facet of advanced Tableau functionality with each post. Even if you can’t solve the challenge, we will walk you through the solution and the logic of how and why the solution works. (More…)

Have you embarked on a journey to create the most insightful dashboard of all time just to realize you have disparate data? Data Integratiion
Whether you are a new analyst entering the work force or a seasoned business intelligence specialist, chances are you have or will encounter the need to combine data from different sources to properly answer your business questions. The reality is visualization software offers limited capabilities in data blending.

As a follow-up to a prior blog post on the Top 7 Data Visualization Best Practices, I wanted to go into a bit more detail about “visual features”. In the prior blog, we discussed “intuitive” data visualizations and how that stems from your brain pre-attentively processing visuals. While it’s not technically accurate, many people think of pre-attentive processing as subconsciously understanding a visual. However you describe it, it is fast! On the order of 40-50 milliseconds for the average person. To put that in perspective, a single flap of a hummingbird’s wings is about 20 milliseconds. Alternatively, the human brain perceives anything around 30 milliseconds as “continuous”, which is how “motion pictures” work. So 40 milliseconds would be around the speed of a single frame in a movie. (More…)

Do you want to create the ultimate, useful, intuitive data visual? Whether you are new to data visualization, familiar with it, or an expert, there is a lot to know besides how to use your favourite data visualization tool. There are best practices relating to the presentation of data in visual form that supersede the mechanics of tools like Tableau, QlikView, PowerBI, etc.

If you properly use visual features, you can “hack” your end-users’ brains without them even knowing it. Within the scientific world is a discipline known as cognitive psychology. It deals with the mental processes such as attention, perception, creativity, thinking, etc. One of the processes in that list is incredibly important to data visualization… perception. Perception is the process by which the human brain takes in external stimuli from its environment. More specific to our discussion, perception is the process by which the brain “sees” information in a dashboard. (More…)

This year’s Gartner Magic Quadrant*, which shows the relative position of each challenger in the business intelligence and analytics space, again positions Tableau as a leader in an increasingly competitive market. For the fourth year in a row, Tableau is a leader and positioned highest in ability to execute.
