Procedure
Feature layer example
This map chart visualization shows Sweden, using two data tables: Sweden Counties and Sweden county capitals. The data includes added census information from 2015, and it has a calculated column indicating cities with populations over 200,000. The map chart visualization includes a feature layer with the following properties.
- Title is set to Sweden Counties (Län)
- Appearance is set to semi-transparent (displaying the OpenStreetMap cycling map TMS layer beneath it).
- Data is set to the data table Sweden county capitals - Swedish Counties (Län).
- Geographic location is set to Feature by County (län).
- The Legend check box is cleared.
- Color is set to the following values.
- Color by: Larger than 200000 (an added calculated column).
- Color scheme: two colors.
- Color items: True (over 200,000) and False (under 200,000), with color selections customized to blue and red.
The result is that the counties with cities over 200,000 (Stockholm, Västra Götaland, and Skåne) are the first color, while all other counties are the second color.
