Unique Values

Unique Values provided by SuperGIS Desktop 3 can not only classify a single field but also multiple fields (3 fields at most). Consequently, readers can recognize the features more rapidly and the features will be more recognizable as well.

To set unique values, firstly choose "Symbology" tab in Layer Properties window and choose "Unique Values" in the "Show" drop-down list. You can set 3 fields for classification at most. After choosing the fields, you can click "Add All Values" or "Add Values" to add the value by clicking. Then, click "OK" to add the value. Also, you can enter the value at the bottom of "Add Values" window and click "Add" to add it. Therefore, the system will be able to classify the value when you add the new values.

Note: The button enables users to open Symbology Selector window and set settings like style, size, and outline width of all the symbols or the symbols you specify (symbols can be multiply selected through Ctrl key). However, users are not allowed to modify color of single symbol through function of the button. Users can utilize the drop-down menu of Color to modify color of all symbols or double-click on a certain symbol to set its color.
