I have a view called Map Items showing a list of map markers in a chart.
Info: I have 3 Accounts in my drupal installation called person1, person2, and admin.
I've set the contextual filter to Author uid: User ID from Logged in user. and its working perfectly, but what I want some additional setting that when there is no logged in user I could set person1's map item to show. Right now when there is no logged in user the view shows the map item of admin user and not person1.
How am I going to accomplish this?
