Is the Visitor Map in Locations report of Piwik PRO Analytics adjustable?
Yes, it is. You can change the granularity of the data being displayed. For example, check only the specific continent (e.g. North America). On the right side of the map widget, there will be the key for the map placed. You can also check only the specific country (e.g. USA) and data for particular cities to appear. Every time you see the map please notice (left upper corner of the map) the number and percentage of visits from the given continent/country/region/city.
Please find out more about it in our article about Visitor Map.
