Once you create your theme, it is likely that you will want to change something about it, such as change ranges, what they look like, their text, and their sort order. You can make these changes and more in the Modify Thematic Map dialog box. To open this dialog:
- In the Layers or Explorer window double-click on the thematic layer to open the Modify Thematic Map dialog box.
- In the Legend Designer window, activate the thematic map's legend with a single click and choose Modify Theme from the Content group on the LEGEND tab. (A double-click opens the Legend Frame Properties dialog box.)
You can also make changes from the THEME tab, which has commands that directly update the most commonly used theme settings and styles. For details, see THEME tab.
Changing the Current Theme Template
A quick way to change a number of theme settings at once is to change the template of the current theme. To merge a template into your current map:
- Open the Modify Thematic Map dialog box by double-clicking on the theme in the Layers or Explorer window.
- Click Merge in the Templates group.
The Merge a Template into the Current Theme dialog box displays with a list of the same type templates as your theme (all range of values templates, for example.)
The Merge feature is only available after creating a thematic map.
- Choose the new template.
- Click OK to return to the Modify Thematic Map dialog box.
- Click OK to display the map with the new thematic template.
The settings in this template will be applied to your theme.
Setting the Zoom Range for a Thematic Layer
To set the zoom range within which the thematic layer displays on the map, in the Layers or Explorer window right-click on the thematic layer and select Layer Properties to open the Layer Properties dialog box.
Changing the Thematic Range in the Legend Designer Window
If you created a legend for your map and it includes the thematic range (the Legend Designer window includes a frame showing the thematic range), then double-clicking on the thematic frame lets you make changes to it. In the Legend Frame Properties dialog box you can change what displays in the legend. Making changes to the legend does not change the map.
