Key Spotfire concept: map chart layers
As you've just seen, Spotfire's standard map is always available as a background Map Layer, and you've seen how it can be divided into sub layers of detail. The map chart has four other types of layers to extend the range of spatial visualizations you can create.
The Marker Layer and Feature Layer are derived from datasets, and one marker or feature layer can be designated as the map chart's interactive layer. You can also change the interactive layer designation dynamically in the chart. Because they are linked to data, the markers on interactive marker layers and the features on interactive feature layers behave like other interactive elements in Spotfire and respond to marking and filtering.
