The Outer Limits

There is nothing wrong with your visualization. Do not attempt to adjust the picture. We control the horizontal. We control the vertical...

On the first viz shown below, we calculate the quadrants of the latitudes and longitudes in order to provide geographic 'slicing' filters. On the second viz shown below, we also created percentile calculations to provide additional filters based upon the individual latitudes and longitudes - essentially, this creates the effect of providing axis range sliders.

The only requirement here is that your latitudes and longitudes must A) exist as actual fields (as opposed to using Tableau's built-in geocoding) and B), must be aggregate, e.g. AVG(latitude or longitude). Thus, your level of detail will affect the construction of this example.

Hopefully I won't get in trouble for stealing the outer limits logo. I mean, geesh, it's almost fifty years old at this point.
