I often spend hours—days, sometimes—formatting a dashboard to death. The end result is mostly something I am proud of, but when I look back at some of the hoops I have jumped through, I question whether they were worth it. If something took two hours to implement and only made a tiny improvement to my dashboard, was it worth it?
In fact, is it worth changing any of the default formats in Tableau? Quite often, the answer is no. Tableau’s defaults are perfectly functional. (I covered this in more detail in my previous blog post "Are Our Defaults at Fault?")
In this post, I want to explore how you can choose which design changes you should implement.
Here at Tableau, we ran an internal viz design competition using US road fatality data. My entry is the viz above.
Being the competitive type, I went all out to put in every design trick I could think of. I identified 30 conscious design decisions to alter the unformatted Tableau dashboard. I scored them based on the impact on the end result and the difficulty in implementing (based on time or complexity).
Below is the result of that scoring process. You can see four quadrants. Each mark is a design/format choice. (You can click each link to go see an explanation on my blog, Gravy Anecdote.)
My scoring is very subjective. I’d love your thoughts. Would you have scored them differently? What design choices do you make, and how would you score them?
How can you apply this kind of model to your own work?
Without a doubt you should do the low difficulty/high impact type of change. After that, as with all things, it depends (discussed in detail on my Huffington Post column). It depends...
For reference, here’s the full list of posts and features:
There are endless different design choices you can make to enhance and improve your visualizations, only a few of which I’ve covered here. I hope I've helped you think about how can you apply this kind of model to your own work.
