Hi all,
I am having problems getting a dual axis map to work. I have attached a workbook and I would like to overlay MAP 2 onto MAP 1. I have followed all of the instructional tutorials that I can find and I can't get the dual axis map to work. PLEASE HELP!
Thank you!
Anne
Hi Anne,
In the workbook there are two separate Tableau data sources with mapping data - the boundaries data and the grocers data. MAP 1 is using the boundaries data, MAP 2 is using the grocers data. However Tableau (as of v2021.1) has a long-standing requirement that all mapping data come from the *same* Tableau data source, and that's why you can't get a map.
With the relationships feature introduced in v2021.2 we can build a single Tableau data source that would work as desired and remove the need for data blending. Since all of the sources in this workbook are extracts I didn't do that (you'd be better off doing it on the native connections prior to extorting), here's an sketch of what the source would look like:
Also since the workbook is built using v2020.4 you could use the Map Layers feature to build the view.
