Use this dialog box to create a theme for a feature source layer, based on a range of conditions. The title of the dialog box changes, depending on the type of geometry in the feature you are theming.
A theme is a collection of rules. Each rule specifies a style and feature label for the features that meet the specified condition. You can add a legend label to provide a description of a rule’s condition.
Create Thematic Rules Based On A Property
- Property

Select the property on which to base the theme.

- Number of Rules
-
Specify the number of ranges to create if Distribution Method is Equal, Quantile, or Jenks (Natural Breaks). Properties containing strings use an Individual Values distribution that does not allow the number of rules to be edited. Adjust the number of rules to control the coarseness of the theme. For more information about distribution methods, see About Theming Features.
- Replace Existing Rules

Specify whether new ranges replace existing rules (ranges) or are added before or after existing rules.

If you theme a layer on a property that contained area information and you used the label text Area:, the label formats might look like the following examples:
<Label Text> <Min> to <Max>
Area: 100 to 200
<Label Text> <Min> - <Max>
Area: 100 - 200
<Min> <= <Label Text> <<Max>
100 <= Area < 200
