Filtering a single axis on a dual axis map

Software:

Tableau Desktop 9.2

Description:

When creating a dual axis map with one layer being a filled map, and the other being pie charts to identify

specific locations; being able to filter only data from a specific axis as opposed to both.

Filled Map data = regions based on U.S. county lines (needs to stay intact regardless of filter application)

Pie Chart data = program locations broken down by individual characteristics (types of training offered at each

location)

Issue:

When filtering pie chart data, non-applicable counties/regions are filtered out leaving "holes" in the map.

Solution:

Leaving the filled map (background) as a static image so to speak and having pie charts change as dictated by

filters.
