Client dashboards are rarely ever “done” and evolve over time from one version to the next. When dashboard functionality or information changes, the descriptive contents of the dashboard have to be manually updated. Also, Tableau dashboards often link to other dashboards, and when they are moved between Tableau sites or Tableau Servers, the links need to be changed. (More…)
As a sales professional, I have the opportunity to connect and speak with a variety of different people in various business sectors – from solopreneurs to large corporations and government agencies. And while they all have different needs, there are a lot of common reasons as to why and when they get BI tools. Or don’t. Here are my anecdotal top 7 reasons why people don’t get BI tools, and tips on when (and how) they should: (More…)
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?
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…)
