Setting a Geographical Field

To set a field as a geographical field (for use with Map Charts), follow the steps below:

1. Right-click the field in the tree, and select 'Set Geographic' from the context menu. This places a “star” icon next to the field name, and opens the geographical level editor.

 

The map that you select for a geo­graphic field applies to all other geographi­cal fields.

2. In the level editor, select the desired region from the 'Map' menu: Asia, Canada, Europe, Mexico, U.S., or World.

3. From the 'Layer' menu, select the geographical layer that corresponds to the data in the selected field.

This specifies the layer of the geographical database against which field values should be matched (e.g., city names should be matched against the city layer, etc.). The options available in the 'Layer' menu depend on the previously selected 'Map' option.

4. From the 'Mapping' menu, select the desired map database.

The Chart Editor attempts to resolve values in the selected geo­graphic field against the corresponding layer in the map database. If all data values are successfully matched, a green check mark is displayed. If some data values cannot be matched, a red question mark is displayed.

5. To resolve any unmatched names, click the red question mark. This opens the 'Geographical Mapping' dialog box. See Resolving Geographical Data for further instructions.

6. Click the 'Apply' button.

To modify the settings for an existing geographical field, right click the field, and select 'Edit Geographic' from the context menu. This opens the geographical level editor described above.

 

To remove the geographical status of a field, right click the field, and select 'Clear Geographic' from the context menu.
