Create a representation

Create a new representation for an existing domain.

When you display a map with such a domain, the newly created representation is selectable in the display options dialog box of the map.

This dialog box appears when creating a new representation:

by opening the File menu of the Main window and choosing the Create Representation command,
by opening the Create item in the Operation-tree, and double-clicking the New Representation item,
by double-clicking the New Representation item in the Operation-list,
when in the Catalog, you right-click a class, group or value domain, and choose the Create Representation item from the context-sensitive menu,
when in a Display Options dialog box of a map with a class, group or value domain, you click the create representation button. The domain of the map, i.e. the domain for which this representation should be created, is already filled out.
when in the Domain Properties sheet of a class, group or value domain, on the Domain tab, you click the create representation button. The domain for which this representation should be created, is already filled out.

Dialog box options:

Representation name:	Type a new name for the representation.
Description:	Type a description for the representation. The description is visible on the status bar of the Main window when moving the mouse pointer over the representation in the Catalog.
Domain:	Select an existing domain for which you want to create this representation. For more information, see below.
Use percentages:	When you chose the system domain Value, select this checkbox when you want to create a representation gradual which shows values as percentages. Clear this checkbox when you want to create a representation value which shows values as values.

Representation types:

A representation class will be created when you select a class or group domain.
In the Representation Class editor you can assign colors to the classes.
A representation value will be created when you select:
- a user-defined value domain,
- the system domain Value while you clear the Use Percentages checkbox, or
- one of the other system value domains for instance system domain Image.
In the Representation Value/Gradual editor you can assign colors to specific values by inserting and editing limits, etc.
A representation gradual will be created when you select the system domain Value while you select the Use Percentages checkbox.
In the Representation Value/Gradual editor you can assign colors to percentage values by inserting and editing limits, etc.

Tips:

The easiest way to create a representation for a map with a certain domain is to open the Display Options dialog box of that map and then click the create button next to the Representation list box.
Default representations for non-system domains:

A new representation class will automatically become the default representation for the selected class or group domain. The representation is linked to the selected domain.
A new representation value will only become the default representation if you selected a user-defined value domain. The representation is linked to the selected domain.

You can view and/or change the default representation of class and group domains and of user-defined value domains in the Properties of the domain.

System domains are not editable and they therefore have a fixed default representation.

For system domains Value and Distance, the default representation is representation gradual Pseudo.
For all other system value domains, the default representation is representation gradual Gray.
