Question
You try to create a map via the Geo Wizard by selecting a subnational "mappable area," but when the map editor opens, no image appears.
Answer
Did you follow this procedure?
- Browse the catalog for subnational data.
- Pick an indicator.
- In the Geography Wizard, pick Geo Type "Mappable Areas."
- Press the "New Map" button in the lower-right to create a map.
- The map editor opens, but no image appears.
To mitigate the problem, do this:
- Open the map editor's Options menu.
- Switch to the Legend option group.
- In the Range Detail frame, change Segments to "1."
- Press the "Apply" button.
- Once the map appears, count the number of regions. If at least two, you can change the Segments value again.
- See if there is a more granular template available, under Options » Series » Map » Area.
The default number of range segments (i.e., buckets into which the data values are partitioned) is three. A map with N areas can be colored with no more than N different colors. If the Mappable Areas template you picked has fewer than three areas, this bug occurs; some of our European metro area maps qualify -- for countries that contain only one or two component areas at a given NUTS level.
