Setting Style Properties for Layers

Creating Themes
You can create themes that allow users to quickly see and understand data on
your map. For example, a typical theme for a point layer could display retail
store locations with a different symbol for each type of store. A polygon layer
theme could display each land use classification with a different color or
shading.
Note
You cannot apply themes to text or buffer layers.
Use the Theme area in the Styles tab in the Map Layer Properties dialog box
to create or change a display theme for the features on the current map layer.

Before you can create a theme, you need to link the layer to a database. For
more information, see “Specifying Data Source Properties for Layers” on
page 153.
For step-by-step instructions, choose Help
Contents, click the Index tab,
and look up “themes, creating.”
Specifying Layer Feature Labeling and
Overposting
Use the Labels And Overposting area in the Styles tab of the Map Layer Prop-
erties dialog box to specify the font, size, color, and map display range of
automatic labeling for this style set, and to control how features overlap on
a layer.

Overposting occurs when feature labels overlap or cover other map features.
To minimize overposting, the default setting prevents a label from being
drawn at a specific zoom level if it will obscure other labels or features on the
map. However, the program will display the label when you zoom in far
enough to allow sufficient space to display it. The source of the map feature
label is the name field of the data source for the layer. Note that you cannot
create labels for buffer layers. For step-by-step instructions, choose
Help
Contents, click the Index tab, and look up “labels for features.”
