This post will be relatively short. There were a few announcements at Tableau Conference-ish over the first couple days that are a huge deal for Tableau Desktop developers. These new feature announcements are certainly not exhaustive but are in my opinion, the highest impact.
Big map changes
Unlimited map layers
This means you aren’t limited to a single analysis that depends on size and/or color of map marks. This really opens up the number of options developers have in creating impactful and insightful maps.
This new feature might raise the question; how can you have multiple layers and a good user experience due to Tableau’s standard interactivity on worksheet?
You can now disable selections on maps
No more inadvertent highlighting and unwanted interactivity. Turn off selections in maps in order to provide a better user experience. This will greatly improve mobile UX due to the tapping and scrolling nature of mobile devices. This will avoid some common frustrations associated with the maps UX.
With multiple layers, you’ll want to be able to control which one appears on the top. Tableau will be providing an easy way to drag and reorder map layers so that the desired layer order can be achieved.
Not map related, but probably the biggest news for beginner and intermediate developers: Tableau Desktop will write your LoDs
You read that right! If you’ve had trouble building level of detail calculations, Tableau is going to help out with that. You’ll be able to select dimensions and measures by holding control, right click, and click on “Create Level of Detail Calculation”. For more complex LOD calculations, this won’t be too big of a deal. But for people struggling to build these calculations, this functionality might bridge the gap between knowing about LODs and understanding LODs.
