If you have created a thematic map, it will be listed as a separate layer in the Layers or Explorer window.
If a theme layer uses a range of values, then the ranges display under the theme layer name. Each range item includes a display check box, a color or pattern swatch, and text describing the range (such as "0 - 25"). To turn off the display for a range, clear its display check box. To make multiple selections in the list, press Ctrl+Click or select a range by pressing Shift+Click.
Note: A Grid thematic layer is a read-only layer and cannot be edited.
To modify the attributes of a thematic Map:
- Double-click the thematic layer in the Explorer window.
- In the Modify Thematic Layer dialog box, change the thematic settings, style, or map legends.
Note: The availability of certain dialog boxes depends on the type of thematic map you are altering.
- Click OK to redraw the map with your changes.
