A simple graph-style panel, the Visit Time Allocations panel allows you to track the average visit time for a given custom region. Because they track one region at a time, simply layering multiple Visit Time Allocation panels, with each one set to a different region, gives you a handy view that tracks and compares all of your regions at once. The Multiple Time-Period and Multiple-Retailer View examples in our Common Example Views documentation page both show how to layer multiple, identical insight panels, each set to measure different sets of data.
