Creating Selection Sets from a Theme

Maptitude allows you to create several selection sets in a single step by converting a color or pattern theme to a group of selection sets. You may want to convert a theme to selection sets for any number of reasons, for example:

  • You want to set different label styles for sales districts where revenue declined
  • You want to classify clients by type (active, prospect, etc.) and display each group separately in a dataview

When you convert a theme to a group of selection sets, a selection set is created for each class in the theme. The color and style settings for each class are automatically copied to the selection set, and the original theme is removed. Note that in most cases the map will look exactly the same. However, you can now modify the display settings, labeling, and other attributes of each class independently.
