Tabeau 2019.2 Release Features
With the latest release of Tableau, the 2019.2 version, there are several awesome new features that the Tessellation team got to try out. Here’s what our team had to say about them!
Vector Mapping (Shaun Davis & John Emery)
I have to choose one? Then I choose Vector Mapping. It’s not a term that resonates outside of the spatial world, but is huge. Vector mapping allows labels, roads and other features to draw faster and in a way that matches our mapping experiences on other platforms. Prior to 2019.2 the mapping environment was basically a set of images that were stitched together and had geographic coordinates associated with them. I’ve embedded a view showing the performance improvements.
Before – Tile
After – Vector
Some of the big changes are how labels redraw at multiple locations along the streets and the absence of adjacent map tiles which are pixelated and draw slowly. The performance improvements are super evident, since I waited until most of the map tiles loaded in the before image, resulting in more time going from a high view to street view. Overall, these mapping improvements match those you expect to see with Google Maps or your chosen mapping platform.
Parameter Actions (Aidan)
I love creating visualizations that users can interact with and explore, so I’m most excited about parameter actions! This opens huge new possibilities for dashboard functionality and I can’t wait to play with them more.
Replace Worksheet in a Dashboard (Alicia)
Ok, you may not think the replace worksheet in a dashboard feature can compete for the thrills and excitement of the new map and parameter action features. BUT I’d like to show you how useful this feature can be.
Here I am swapping out a state map for a hex map and vice versa using the swap/replace worksheet feature in Tableau v2019.2.
And here I am using the old method of dragging the worksheet onto the dashboard and removing the original worksheet. Notice how I have to take additional steps to get the formatting right again.
It’s a hassle. First, I have to remove the legends that automatically came in with the worksheet. Second, I need to reformat the worksheet. My accent borders on the dashboard were created by having a dark background for the container. So now I have to change the background color of the worksheet from none to white and also change the padding of the worksheet.
Basically, I could swap out the worksheets five times in the same amount of time it takes me to reformat everything using the old method of dragging a worksheet in. So thank you Tableau for the replace worksheets feature!
