Adding a marker layer
Markers display positional coordinates on a map in Spotfire Business Author. The markers are customizable shapes that are placed on the map based on the position coordinates (latitudes and longitudes) or based on the geographic information provided in your data that represent zip codes, cities, counties, regions or countries.
Prerequisites
The data must contain geographical or positional information. If the data contains no geographic coordinates (latitude and longitude), Spotfire Business Author can place markers automatically in the center of supported administrative areas.
Procedure
Marker layer example
This map chart shows Sweden with a nearly-transparent feature layer, showing county boundary lines, and a marker layer with the following properties.
- Title is set to Sweden county capitals.
- Appearance is set to opaque.
- Data is set to Sweden county capitals, with marking.
- Geographical location is set to Coordinate-based.
- Shape is set to Shape by column values, and the column set to cities larger than 200,000. (Three cities, Stockholm, Malmö, and Göteborg meet this condition (TRUE), so their shapes are filled circles, and all other county capitals are filled squares.)
- Legend is set to display, with Marking, Color by, Shape by, and Size by available.
- Color is set to Color scheme with two colors, Color by set to Sum(Population 2015) so smaller cities and towns appear in blue, and the larger cities appear in red.
- Size is set to Size by Sum(Population 2015) with marker size slightly enlarged. (Stockholm's marker is significantly larger but the smallest markers are still clearly visible.)
- Drawing order is not set because the map has no overlapping markers.
- Jittering is not set because the map has no overlapping markers.
- Line connection is not set.
- Labels is set to display the names of all county capitals.

- Adding a rule to a color scheme
Rules function as exceptions to the rest of the color scheme. You can use them in all kinds of visualizations. The collection of available rules is different for categorical columns and continuous columns. You can add multiple color rules. - Showing directions using marker rotation in a map chart
Some marker shapes, for example arrows, indicate directions. If you, in a map chart marker layer, rotate such markers, you can visualize directions of motions. What you need is a column that contains values that can be interpreted as degrees. - Connecting map markers with lines
Use lines to connect markers on a map to show the movement of people or items from one specified location to another.
