Defining override conditions for representations

In addition to the basic rule for the calculated representation, you can also define overrides for the representation rule. This allows you to create conditions in which the symbol size or other properties change depending on values in a specified field.

注意:

Only fields with a Double data type can be used as override fields.

步骤:

1. Right-click the layer for which you want to define the calculated representations and click Properties.

   The Layer Properties dialog box appears.

2. Click the Calculated Representations tab.

3. Click the ellipsis (...) in the Explicit Override Fields field.

   The Representation Rule dialog box appears.

4. Click the Display field overrides button .
5. Click the arrow next to the field you want to use to override the current representation rule.
   注意:

   Only fields of double data type are going to appear in the drop-down list.

6. Click OK.
