If you want to draw the same data multiple times in different ways to create the effect of complex line styles, you can specify multiple styles for a single style set. For details, see "Creating Complex Line Styles with Polylines" on page 161.  For step-by-step instructions on specifying display ranges, choose Help Contents, click the Index tab, and look up "display ranges." Specifying Map Layer Styles You can specify different display styles, such as new symbols for a point layer or font style for a text layer, for each layer in your map. Use the Styles area of the Styles tab in the Map Layer Properties dialog box to specify how a layer is displayed. When themes are disabled, the Styles list contains only one display style (a symbol for point layers, text font for text layers, line style for polyline layers, or fill style for polygon layers), as shown in the following illustration. The settings you specify for this particular style determine how all features on the layer are drawn. However, on polyline layers, you can add additional display styles if you want to overlap display styles to create the effect of complex line styles. For more information, see "Creating Complex Line Styles with Polylines" on page 161. This button is enabled for text and point layers only. When themes are enabled, there is a separate entry in the Styles list for each theme category. You specify settings for each theme category separately. For more information, see "Creating Themes" on page 163. Specifying Size Units for Text and Point Layers Online Help Index size units for text and point layers With text and point layers, you can specify whether to use screen units (inches or centimeters) or mapping coordinate system units to express the width and height of features in the map. To specify size units, you click the Size Units button in the Styles tab of the Map Layer Properties dialog box. For step-by-step instructions, choose 158 | Chapter 9 Working with Map Layers
