To Theme Features

You can use the theming tool to create themes for layers from feature sources such as SDF, SHP, Oracle Spatial, or ArcSDE.

To create a theme for a feature layer

1. In Display Manager , select a feature layer. Click the Style icon in the toolstrip.
2. In the Style Editor, under Scale Ranges, select the scale range to theme.
3. In the Polygon Style, Point Style, or Line Style area, click New Theme.
4. To analyze features based on values that fall into various numerical ranges, do the following in the Theme dialog box:
   • For Property, select the property on which to base the theme.
   • For properties with numeric values, specify the Minimum Value and Maximum Value for the range.
   • For properties with numeric values, select a Distribution method.

     The first rule includes the Minimum Value and the last rule includes the Maximum Value. Styles are interpolated across the range.

     You can specify the number of rules 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.

   • If you are editing an existing theme, you can replace any existing rules by selecting Replace existing rules.
5. The default Style Range shows the styles that will be used for each rule. Your options depend on the type of geometry stored on this feature layer.
6. To add labels to features in the theme, do the following:
   • Select the Create Feature Labels check box.
   • Next to Label Ramp, click
   • Select Create A Label and specify the criteria for the labels.
7. To create legend labels for the theme, do the following:
   • Select the Create Legend Labels check box.
   • For Legend Text, enter the text to appear next to each rule in the legend.
   • For Label Format, specify how to display the legend label.
