In version 2021.4, map layers were updated to allow each map layer to use a separate data source. This removes the need to create relationships or joins between your spatial files prior to using them in map layers.
Creating a Three Layer Map
In this video, I cover a brief history of making multiple layer maps in Tableau. I then step through how to use map layers in version 2021.4 to create a three-layer map with polygons, lines and points and also how to use the different map layer options such as:
- Disable Selection and
- Add to Zoom Extent
Video Tutorial
The video also covers some basic map formatting, such as changing the background map and map layers shown in the view.
