According to the GeoAnalytics documentation there is support for UK Postcodes as geo data in the default qlik sense maps. I have a file containing postcodes that I've tried loading through both the script editor and the data manager, it doesn't recognise the field as a geo field. If i go to edit the field data type to geo data I only see a limited list (Counrty, City, ISO code...), no option for postcode. Any ideas?
